Abstract:
Many of Canada's conifer seed orchards are entering their productive phase. In most, if not all seed orchards, insect pest management will be required in order to meet the seed production targets. Canadian seed orchard managers will soon need to know the basic requirements and what information is available to implement an insect pest management program. In this review, a synthesis is provided of the major components of an integrated pest management program for cone and seed insects. A list of the insect pests of conifer cones and seeds in Canada as well as features of their life cycles and population dynamics that could influence pest management strategies is presented. Current and future needs for insect damage appraisal and insect monitoring techniques are discussed. Finally, the various strategies and tactics to control insects are reviewed. Key words: conifer seed orchards, cone insects, seed insects, pest management strategies, integrated pest management

Abstract:
Abstract Stored-product entomologists have a variety of new monitoring, decision-making, biological, chemical, and physical pest management tools available to them. Two types of stored-product insect populations are of interest: insects of immediate economic importance infesting commodities, and insects that live in food residues in equipment and facilities. The sampling and control methods change as grain and grain products move from field to consumer. There are also some changes in the major insect pest species to take into consideration. In this review, we list the primary insect pests at each point of the marketing system, and indicate which sampling methods and control strategies are most appropriate. Economic thresholds for insect infestation levels developed for raw commodity storage, processing plants, and retail business allow sampling-based pest management to be done before insect infestations cause economic injury. Taking enough samples to have a representative sample (20-30 samples) will generally provide enough information to classify a population as above or below an economic threshold.

Abstract:
AbstractThe use of insecticides in flowering oilseed rape (Brassica napus L.) against pest insects such as the brassica pod midge (Dasineura brassicae W.) often conflicts with the protection of pollinating and beneficial insects. Dasineura brassicae is a major pest insect in European oilseed rape production. However, a comprehensive and sustainable pest control strategy within the framework of integrated pest management (IPM) does not exist, and little research on the insect has been published during the past two decades. This paper reviews the existing knowledge about D. brassicae along its life cycle and is intended to form the basis for further research activities on pod-damaging pest insects in oilseed rape. Important knowledge gaps are identified, regarding the significance of natural enemies, diapause induction, and predictions on damage potential, based on initial pest insect population. The short lifespan of the adults is particularly challenging in praxis. The implementation of IPM for D. brassicae is discussed on the basis of the four IPM steps (set an economic threshold, establish pest monitoring, preventive measures, and direct control measures) and remaining hurdles, as well as potential solutions for a better IPM, are identified. For D. brassicae, there is no science-based economic threshold and no applicable monitoring methods for farmers, which hinders a field-specific damage forecast and the precise timing of insecticide applications. Research into improved monitoring (e.g. selective attractants, real-time monitoring using remote-sensing technologies) appears to be a promising step towards an integrated pest management of D. brassicae.

Abstract:
Methods for crop protection based on semiochemicals show advantages over methods based on conventional insecticides. Applications of semiochemicals for insect pest management have, however, been limited. Some recent studies carried out in an interdisciplinary research program by five research groups in Sweden are presented. In spite of the chemodiversity in nature, it is striking that many simple and common compounds are important as chemical signals. This paper focuses on some examples of such simple signals, which are now used for monitoring and suppression of pest insects.

Abstract:
Studying the presence and movement of insects is important in biological research for practical purposes regarding control of pests and environmental monitoring. Detection of insects by conventional trapping (e.g. the Rothamsted Insect Survey) and tracking technologies (e.g. the Rothamsted Radar Entomology Unit) have been effective for monitoring and forecasting pest migration but often require significant investment in capital costs and/or staff time. Insect detection using imaging of natural fluorescence (without additional fluorescent dyes) has been considered less, and much of the work on natural fluorescence in the animal world has been on marine organisms. Work on terrestrial arthropods has been more limited and restricted primarily to non-insect arthropods. Very early work on the distribution of fluorescent pigments in butterflies was demonstrated using long wave mercury vapour lamps followed by more work in the 1950s on butterflies, arthropods; including beetles, spiders and millipedes, cockroaches and eggs of Orthoptera. These studies often involved qualitative approaches; dissecting the animals and investigating internal organs and fluids for fluorescence as well as whole body studies. More recent studies have included quantitative work on butterflies and pest insects plus fluorescence studies in damselflies, moths, millipedes, bees and spiders. Fluorescence in juvenile stages is a property used for detection of flies and beetles in food stuffs. The vast majority of insects, however, have not been investigated for fluorescence and even in those taxa that have been studied, e.g. butterflies, the dataset is incomplete. The easiest way to observe fluorescence is to illuminate a subject with a known waveband of light in otherwise darkness and view or record an image via a filter that blocks the wavelength of the illuminating light. Any light viewed or captured at a different wavelength to the illumination, must have been produced by fluorescence. In contrast, some living organisms themselves can produce light or luminescence by internal chemical means. This work aimed to look at the potential of using natural fluorescence to detect and identify insects, particularly pests.

Abstract:
Insects are a common problem in stored produce. The author describes the extent of the problem and approaches to countering it. Stored products of agricultural and animal origin, whether edible or non-edible, are favourite food for insect pests. Durable agricultural produce comprising dry raw and processed commodities and perishables (fresh produce) are vulnerable to insect pests at various stages from production till end-use. Similarly, different animal products and museum objects are infested mainly by dermestids. Insect pests proliferate due to favourable storage conditions, temperature and humidity and availability of food in abundance. In addition to their presence in food commodities, insects occur in storages (warehouses, silos) and processing facilities (flour mills, feed mills). Insect infestation is also a serious issue in processed products and packed commodities. The extent of loss in stored products due to insects varies between countries depending on favourable climatic conditions, and pest control measures adopted. In stored food commodities, insect infestation causes loss in quantity, changes in nutritional quality, altered chemical composition, off-odours, changes in end-use products, dissemination of toxigenic microorganisms and associated health implications. The insects contribute to contaminants such as silk threads, body fragments, hastisetae, excreta and chemical secretions. Insect activity in stored products increases the moisture content favouring the growth of moulds that produce mycotoxins (e.g., aflatoxin in stored peanuts). Hide beetle, Dermestes maculatus infesting silkworm cocoons has been reported to act as a carrier of microsporidian parasite Nosema bombycis that causes pebrine disease in silkworms. In dried fish, insect infestation leads to higher bacterial count and uric acid levels. Insects cause damage in hides and skins affecting their subsequent use for making leather products. The trend in stored product insect pest management is skewing in favour of pest prevention, monitoring, housekeeping and finally control. Hermetic storage system can be supplemented with CO2 or phosphine application to achieve quicker results. Pest detection and monitoring has gained significance as an important tool in insect pest management. Pheromone traps originally intended for detection of infestations have been advanced as a mating disruption device ensuing pest suppression in storage premises and processing facilities; pheromones also have to undergo registration protocols similar to conventional insecticides in some countries. Control measures involve reduced chemical pesticide use and more non-chemical inputs such as heat, cold/freezing and desiccants. Furthermore, there is an expanding organic market where physical and biological agents play a key role. The management options for insect control depend on the necessity or severity of pest incidence. Generally, nonchemical treatments, except heat, require more treatment time or investment in expensive equipment or fail to achieve 100% insect mortality. Despite insect resistance, environmental issues and residue problems, chemical control is inevitable and continues to be the most effective and rapid control method. There are limited options with respect to alternative fumigants and the alternatives have constraints as regards environmental and health concerns, cost, and other logistics. For fumigation of fresh agricultural produce, new formulations of ethyl formate and phosphine are commercially applied replacing methyl bromide. Resistance management is now another component of stored product pest management. In recent times, fumigation techniques have improved taking into consideration possible insect resistance. Insect control deploying nanoparticles, alone or as carriers for other control agents, is an emerging area with promising results. As there is no single compound with all the desired qualities, a necessity has arisen to adopt multiple approaches. Cocktail applications or combination treatments (IGRs plus organophosphorus insecticides, diatomaceous earth plus contact insecticides, nanoparticles plus insecticides/pathogens/phytocompounds and conventional fumigants plus CO2; vacuum plus fumigant) have been proved to be more effective. The future of store product insect pest management is deployment of multiple approaches and/or combination treatments to achieve the goal quickly and effectively.

Abstract:
Insect Monitoring includes collecting information about insect activity with the help of using traps and lures. Many different types of traps are used and they can be divided into the following types - Light traps, Sticky Traps and Pheromone Traps. After trapping the insect, the next step involves monitoring tools to monitor the further behavior of insects. Monitoring includes checking of crop fields for early detection of pests and identification of pests. Identification helps in finding which are the best naturally occurring control agents and assessing the efficiency of pest control actions that already have been taken. The main purpose of this paper is to design the insect monitoring system is to assess insect activity and gain population estimates so we can deploy a solution that will be most effective at protecting our crops. This system involves the use of traps and lures to get information on insect activity. Traps are strategically placed throughout the crop and include natural semi-chemical attractants to draw insects into the traps.

The international importance of the potato crop needs no stressing and its protection from insect pests is correspondingly important. This article reviews the wide variety of control methods currently in use. In present circumstances integrated pest control methods are desirable on environmental grounds, but in practice the careful monitoring required makes this difficult for the individual grower.

Abstract:
Invasive species are alien to the ecosystem under consideration and cause economic or environmental damage or harm to human health. Two alien insects that fit this description are the brown marmorated stink bug, Halyomorpha halys and the spotted lanternfly, Lycorma delicatula. Both invaders are polyphagous pests that feed on a myriad of plant species and inflict severe crop losses. As sustainable control methods depend on the accurate monitoring of species’ invasion and involve the use of natural enemies, we addressed these two facets by exploring novel monitoring techniques and deciphering host-parasitoid interactions for improved integrated pest management. Thus, we adopted ‘BugMap’, a citizen science initiative that enables students, farmers and everyday citizens to report sightings of H. halys from Italy, with emphasis on Trentino-Alto Adige. Aside from fostering citizen participation in scientific endeavors and the enhanced literacy that ensues, BugMap helped uncover the invasion dynamics of H. halys and forecast its potential distribution in Trentino, all while coordinating technical monitoring and informing management strategies. The most promising agent currently under study for the classical biological control of H. halys is the Asian egg parasitoid Trissolcus japonicus. To assess the wasp’s potential non-target impacts, we investigated its foraging behavior in response to chemical traces ‘footprints’ deposited by its main host H. halys and by a suboptimal predatory species, the spined soldier bug, Podisus maculiventris. Wasps exhibited a ‘motivated searching’ when in contact with footprints originating from both species. However, T. japonicus arrestment was significantly stronger in response to H. halys footprints, compared with P. maculiventris, implying the presence of underlying chemical cues that shape its natural preferences. A series of GC-MS chemical analyses revealed that n-tridecane and (E)-2-decenal were more abundant in H. halys footprints and are probably the key components utilized by the wasp for short range host location. The function of the aforementioned compounds was studied, n-tridecane acted as an arrestant, prolonging T. japonicus residence time, whereas (E)-2-decenal fulfilled its presumed defensive role and repelled the wasp. These results shed new light on the chemical ecology of T. japonicus and help expand the understanding of parasitoid foraging and its implications for classical biological control. Moving to the other invader L. delicatula, an egg parasitoid Anastatus orientalis was reported attacking it at high rates in its native range in Eastern Asia and may play a key role in reducing its populations there. A series of bioassays revealed that wasps responded to footprints deposited by L. delicatula gravid females by initiating a strong searching behavior. Moreover, A. orientalis preferred to oviposit in egg masses with intact oothecae, suggesting that the host’s egg covering functions as a trigger for A. orientalis probing and oviposition. Thus, A. orientalis not only overcomes, but also reverses an important line of host structural defense for its own fitness gains. This dissertation discusses the benefits of combining citizen science with traditional monitoring, and the usefulness of decoding host-parasitoid interactions to design more efficacious management strategies of invasive insect pests.

Timely enactment of insect pest management and incursion mitigation protocols requires development of time-sensitive monitoring approaches. Numerous passive monitoring methods exist (e.g., insect traps), which offer an efficient solution to monitoring for pests across large geographic regions. However, given the number of different monitoring tools, from specific (e.g., pheromone lures) to general (e.g., sticky cards), there is a need to develop protocols for deploying methods to effectively and efficiently monitor for a multitude of potential pests. The non-random movement of the Hessian fly, Mayetiola destructor (Say) (Diptera: Cecidomyiidae), toward several visual, chemical, and tactile cues, makes it a suitable study organism to examine new sensor technologies and deployment strategies that can be tailored for monitoring specific pests. Therefore, the objective was to understand Hessian fly behavior toward new sensor technologies (i.e., light emitting diodes (LEDs) and laser displays) to develop monitoring and deployment strategies. A series of laboratory experiments and trials were conducted to understand how the Hessian fly reacts to the technologies and how environmental factors may affect the insect’s response. Hessian fly pupae distribution within commercial wheat fields was also analyzed to determine deployment of monitoring strategies. Laboratory experiments demonstrated Hessian fly attraction to green spectrum (502 and 525 nm) light (LEDs), that response increased with light intensity (16 W/m2), and that they responded in the presence of wheat odor and the Hessian fly female sex-pheromone, but, response was reduced under ambient light. These laboratory experiments can be used to build a more targeted approach for Hessian fly monitoring by utilizing the appropriate light wavelength and intensity with pheromone and wheat odor to attract both sexes, and mitigating exposure to ambient light. Together this information suggested that light could be used with natural cues to increase attraction. Therefore, a light source (green laser display) was applied to a wheat microcosm, which resulted in greater oviposition in wheat covered by the laser display. Examination of Hessian fly pupal distribution within commercial wheat fields showed that proportion of wheat within a 1 km buffer of the field affected distribution between fields. This helps to inform deployment of monitoring strategies as it identified fields with a lower proportion of wheat within a 1 km buffer to be at higher risk Hessian fly infestation, and therefore monitoring efforts should be focused on those fields. Together this work demonstrates Hessian fly behavior toward new sensor technologies, how those technologies interact with environmental cues, and how environmental composition affects pupal distribution. Collectively this information will enable cheaper, more accurate and more efficient monitoring of this destructive pest.

Abstract:
False codling moth (FCM), Thaumatotibia leucotreta (Meyrick) (Lepidoptera: Tortricidae) is considered the most important indigenous pest of citrus in southern Africa. It is recognized by several markets as a phytosanitary organism and the efficient control of this pest is now more important than ever. The pheromone communication between the male and female moths has been exploited in order to control FCM through the sterile insect technique (SIT). The sterilized males used for all SIT programmes across South Africa come from a colony that originates from wild material collected from the Citrusdal area of the Western Cape Province. The aim of this study was to determine if any differences in attractiveness of females to males exist between different geographical populations of FCM and if so what impact this would have on the male’s ability to locate females from other populations via the volatile sex pheromone released by the female. Laboratory trials with Y-tube olfactometers and flight tunnels tested the attraction of male moths to virgin females, but did not yield any consistent results. Field experiments were conducted with sterile male Citrusdal moths released and recaptured in yellow delta traps in two separate trials. For one trial, the traps were baited with live virgin females from five different geographical populations including Addo, Nelspruit, Marble Hall, Citrusdal and the Old colony, which is a mixture of several populations. For the other trial traps were baited with various synthetic pheromone blends including three regional blends which included South Africa, Ivory Coast and Malawi and three commercial blends including Pherolure, Isomate and Checkmate. For the virgin female trial the Citrusdal males showed a significant preference for females from their own population. There was also a significant difference in the recaptures from the different synthetic pheromones. The South African blend was the most attractive of all the regional and commercial blends. A cross-mating trial was also conducted under laboratory conditions in petri dishes with five different FCM populations including Citrusdal, Addo, Marble Hall, Nelspruit and Old (mixed origin). Females produced more eggs when mated with males from the same population for the Addo, Marble Hall, Nelspruit and Old (mixed origin) populations. The only case in which this was statistically significant was for the Marble Hall population. All the crosses produced viable eggs and the origin of the male or female did not influence egg hatch. The results from this study may lead to improvements in both the control and monitoring of FCM populations. The control methods include mating disruption, attract-and-kill and SIT. Tailoring these methods for a specific growing area with a pheromone blend originating from the area or releasing sterile moths from a colony that originates from the area may optimize the available monitoring and control options.

Abstract:
The Queensland fruit fly, Bactrocera tryoni (Froggatt) (Diptera: Tephritidae), a major pest of horticulture in eastern Australia, is a relatively poor coloniser of new habitat. This thesis examines behavioural properties that might limit the ability of B. tryoni to establish new populations. As the potential for B. tryoni to establish an outbreak population may be most directly limited by mechanisms associated with dispersal and mating behaviour, these two factors were the focus of this research project. The relevance of dispersal and mating behaviour for control of outbreak populations was assessed. Dispersal (i) Dispersal patterns of males and females are not different. Dispersal of post-teneral male B. tryoni from a point within an orchard near Richmond, New South Wales, was monitored following temporally replicated releases. Application of sterile insect technique (SIT) requires knowledge of dispersal from a release point so that effective release rates can be determined. In addition, dispersal following introduction to new habitat can lead to low or negative population growth and an Allee effect. In Spring and Autumn, 2001 � 2003, three different strains of B. tryoni were released: (1) wild flies reared from infested fruit collected in the Sydney Basin; (2) a laboratory-reared strain with a colour mutation (white marks); and (3) sterile flies obtained by gamma-irradiation of a mass-reared strain. Dispersal was monitored using a grid of traps baited with the male attractant, cuelure. During the majority of releases, flies were massmarked using a self-marking technique and fluorescent pigment powder to enable identification of recaptured flies. A preliminary study found that fluorescent pigment marks had no effect on adult survival and marks did not fade significantly in the laboratory over a period of five weeks after eclosion. As cuelure repels inseminated sexually mature female B. tryoni, unbaited, coloured flat sticky traps, and black and yellow sticky sphere traps baited with a food lure (protein autolysate solution) were used to supplement traps baited with cuelure. The effectiveness of these two sticky trap types was assessed, and recaptures used to compare patterns of dispersal from a release point by male and female B. tryoni. Fluorescent yellow (chartreuse), green, and clear unbaited flat sticky traps were relatively ineffective for monitoring dispersal of sterile male and female B. tryoni, recapturing only 0.1% of released sterile flies. Monitoring dispersal with sticky ball traps baited with protein autolysate solution was more successful, with yellow spheres and black spheres recapturing 1.7% and 1.5%, respectively. Trap colour had no effect on recaptures on flat sticky traps or sticky spheres. Equal recapture rates on yellow and black sticky sphere traps suggests that the odour of yeast autolysate solution was more important than colour for attraction of post-teneral flies to traps. Using the results of recaptures on odoriferous black and yellow sticky sphere traps within one week of release, regression equations of male and female recaptures per trap were found to be similar (Figure 4-3). This is the first study to clearly indicate that post-teneral dispersal patterns of male and female B. tryoni released from a point do not differ, enabling the use of existing models to predict density of both sexes of B. tryoni following post-teneral dispersal. (ii) Males disperse further in Spring than in Autumn, but this is not temperature-related. Analysis of replicated recaptures in traps baited with cuelure revealed that dispersal of male B. tryoni in an orchard near Richmond, New South Wales, was higher in Spring than in Autumn (Figure 5-6). As the maximum daily temperature was significantly higher in Spring than in Autumn this result was unexpected, since earlier studies have found that B. tryoni disperse at the onset of cool weather in search of sheltered over-wintering sites. Dispersal of post-teneral B. tryoni may have been affected by habitat suitability; it was found that seasonal trends in dispersal could have been influenced by local habitat variables. Low mean dispersal distances in Autumn may be explained by the presence of fruiting hosts in the orchard, or the availability of resources required by over-wintering flies. There was no significant correlation between temperature and mean dispersal distance, suggesting that higher rates of dispersal cannot be explained by temperature-related increases in activity. Recapture rate per trap was significantly negatively correlated with increasing daily maximum and average temperature. This may have consequences for detection of B. tryoni outbreaks in quarantine areas due to reduced cuelure trap efficiency. (iii) Maturity and source variation affect dispersal and response to cuelure. This research indicated that most male and female B. tryoni do not disperse far from a release point, suggesting that an invading propagule would not spread far in the first generation. However, there is considerable variation in flight capability among individuals. Comparison of wild, laboratory-reared white marks, and gamma-irradiated sterile male B. tryoni indicated that mean dispersal distance and redistribution patterns were not significantly affected by fly origin. Despite no difference in dispersal distance from the release point, recaptures of wild and sterile males per Lynfield trap baited with cuelure were highest within one week after release, whereas recaptures of white marks males per trap increased in the second week. This result may offer evidence to support the hypothesis that sterile male B. tryoni respond to cuelure at an earlier age. Rearing conditions used to produce large quantities of males for sterilisation by gamma-irradiation may select for earlier sexual maturity. Mating Behaviour (i) Density and sex ratio do not affect mating, except at low densities. Demographic stochasticity in the form of sex ratio fluctuations at low population density can lead to an observed Allee effect. The effect of local group density and sex ratio on mating behaviour and male mating success of a laboratory-adapted strain of B. tryoni was examined in laboratory cages. In the laboratory-adapted strain of B. tryoni used in this study, a group of one female and one male was sufficient for a good chance of mating success. The proportion of females mated and male mating success was not significantly affected by density or sex ratio, although variability in male mating success was higher at low density. This could indicate that mating success of B. tryoni can be reduced when local group density is low owing to decreased frequency in encounters between males and females. (ii) Mass-reared males exhibit aberrant mating behaviour, but this does not reduce mating success. Strong artificial selection in mass-rearing facilities may lead to decreased competitiveness of sterile males released in SIT programs as a result of alteration or loss of ecological and behavioural traits required in the field. The effects of domestication and irradiation on the mating behaviour of males of B. tryoni were investigated by caging wild, mass-reared and sterile (mass-reared and gammairradiated) males with wild females. Mating behaviour of mass-reared males was different from that of wild males, but behaviour of wild and sterile males was similar. Mass-reared males were found to engage in mounting of other males much more frequently than wild and sterile males, and began calling significantly earlier before darkness. Male calling did not appear to be associated with female choice of mating partners, although this does not exclude the possibility that calling is a cue used by females to discriminate between mating partners. Conditions used to domesticate and rear large quantities of B. tryoni for SIT may select for an alternative male mating strategy, with mass-reared males calling earlier and exercising less discrimination between potential mating partners. Despite differences in behaviour of wild, mass-reared and sterile males, frequency of successful copulations and mating success were similar. (iii) Pheromone-calling by males was increased in larger aggregations but this did not result in significantly more female visits. Finally, large laboratory cages with artificial leks were used to investigate the importance in B. tryoni of male group size for female visitation at lek sites and initiation of male pheromone-calling. Calling propensity of male B. tryoni was increased by the presence of conspecific males. Females visited the largest lek more frequently than single males, but there was no correlation between lek size and female visitation. Female B. tryoni had a limited capacity to perceive a difference between the number of calling males; female visitation at leks was only weakly associated with male calling, suggesting that lek size and the number of pheromone-calling males may not be the only factor important in locating mates in B. tryoni. The weak, but positive correlation between male calling and female visitation may indicate that passive attraction maintains lek-mating in B. tryoni. Further studies are essential on mating behaviour of B. tryoni, including identification of male mating aggregations in the field, measurement of habitat variables associated with male aggregations, the influence of density on wild B. tryoni mating success, and the role of pheromone-calling, in order to optimise use of SIT for control of this pest.

The European House Borer (EHB) is a timber pest which attacks dead timber. This pest can cause large scale damage to wooden structures and has already spread throughout many parts of the world. The larvae usually remains undetected for many years while it busily inflicts irrevocable and substantial harm to the timber. Since the pest was first discovered in Western Australia in 2004 the Government has endeavoured to extinguish its existence. In this research, an electronic sensor has been developed in order to detect the presence of EHB larvae in timber. Only an accurate detection can allow for selective treatment, which is required in order to eliminate the pest. In the past no reliable detection methods were available. However, with the developed acoustic sensing device, non-destructive and reliable detection of EHB is now possible. The developed handheld device is capable of analysing the acoustic emissions from a timber structure which allows for determining whether or not EHB is present in its vicinity. Depending on the level of the infestation, the detection can take as little as a few seconds. The tests, which have been carried out on infested timber beams in a secured laboratory, show a reliable detection of the larvae over a distance of several metres. The research discusses the challenges encountered throughout the development of the acoustic sensor and the limitations of the technology. Also presented are other potential applications for the device and areas which require further research in order to improve the efficiency of the sensor.

Abstract:
The Eurasian spruce bark beetle Dendroctonus micans is a major pest of spruce which is expanding its range in France, Turkey, England and Wales. Its monospecific predator Rhizophagus grandis has followed naturally the bark beetle into most areas and, since the 1960s, has also been mass-produced and successfully released within newly infested locations.

In this scope, the development of an effective trapping method would be very useful to assess the bark-beetle presence at previously uninfested sites, or predator establishment after release or natural spread. We demonstrated the efficiency of oxygenated monoterpenes-baited kairomone traps to monitor R. grandis in various epidemiological conditions, including areas localized behind or at the limit of the pest’s distribution, or in areas where artificial releases were performed. Because the predator is strictly species-specific, another exciting possibility offered by the kairomone trapping is the indirect monitoring of the pest itself in areas of unknown status (e.g. areas under colonization, or considered as at risk at medium- term).

R. grandis is also considered as one of the most valuable natural enemies to strike aggressive North-American Dendroctonus species. In this respect, R. grandis has been recently applied in a neo-classical biological program against the red turpentine beetle D. valens, which invaded China from North America in the late 1990’s. In laboratory tests conducted on pine logs in the laboratory, or on living pine trees in the field, we demonstrated that R. grandis adults can successfully enter and reproduce into D. valens galleries.

In Europe, R. grandis is the only species regularly found in the brood systems of D. micans, where adults and larvae attack the gregarious larvae of their prey. In such enclosed systems, R. grandis’ functional response is therefore influenced by various interrelated components, such as the prey density, the predator density, or the prey distribution. Measuring the predator’s success in terms of larval survival and growth rates, we demonstrated the time spent by R. grandis larvae to wound and kill their prey to be the main factor limiting their development. This factor may be considerably influenced by the proportions of diseased, wounded or molting prey rise in the brood system, for instance as a result of an increase in prey density, or due to the presence of conspecific adults (which wound their prey but do not consume them entirely). Furthermore, our tests suggest that no cannibalism or noticeable intraspecific competition occurred between R. grandis larvae, whereas some lighter mode of competition probably took place.

R. grandis also exhibits a reproductive numerical response to prey density, which mainly relies on the perception of chemical stimuli and inhibitors released in the bark beetle brood system. In the current study, we developed a non-destructive approach to follow the dynamics of volatile compound production, using sequential sample collection on SPME fibers. Our tests demonstrated that the larval activity of D. micans or D. valens strongly influences the release of some oxygenated monoterpenes. However, our attempts to correlate the relative quantities of some identified chemicals to offspring production were less successful as it concerns the identification of potential oviposition stimuli and inhibitors.

The problematic rose by the progression of D. micans, as well as detailed results of each of the described above studies are discussed in the two published papers and the three manuscripts forming this thesis. Bringing all these studies together, several perspectives are also presented in the general discussion.

Ravageur des épicéas, Dendroctonus micans est toujours en voie d’extension en France, en Turquie, en Angleterre et au Pays de Galles. Dans la plupart de ces zones, le dendroctone est accompagné de manière naturelle par son prédateur monospécifique, Rhizophagus grandis. Depuis les années 1960, le prédateur a également fait l’objet d’une production de masse et de programmes de lâchers dans les zones d’arrivée récente du scolyte.

Dans le cadre de la lutte biologique contre D. micans, les gestionnaires forestiers doivent donc estimer au plus tôt la présence du ravageur dans des zones jusque là indemnes, mais également vérifier l’établissement du prédateur par progression naturelle ou résultant d’introductions délibérées. Dans la présente étude, nous avons démontré l’efficacité de pièges d’interception appatés à l’aide de monoterpènes oxygénés pour la capture de R. grandis. Celle-ci s’est faite dans différentes conditions épidémiologiques, incluant notamment des zones situées en arrière du front de progression du scolyte et des zones où des lâchers artificiels ont été réalisés. Comme R. grandis est strictement inféodé au dendroctone, un autre avantage de la technique est la possibilité de réaliser un dépistage indirect du ravageur dans les zones où son statut est incertain (zones en cours de colonisation, ou considérées comme à risque à moyen terme).

Par ailleurs, R. grandis est également considéré comme un des meilleurs ennemis naturels potentiels pour lutter contre d’autres espèces de Dendroctonus aggressifs. Dans cette optique, R. grandis a été récemment utilisé dans un programme de lute biologique contre D. valens, ravageur invasif arrivé en Chine dans la fin des années 1990 en provenance d’Amérique du Nord. Nous avons démontré la capacité de R. grandis à s’introduire et à se reproduire dans les galeries de D. valens lors de tests de laboratoire, mais aussi sur des arbres vivants en pinèdes.

En Europe, R. grandis est strictement inféodé aux galeries de D. micans, où larves et adultes du prédateur s’attaquent aux larves grégaires du scolyte. Dans ce système clos, la réponse fonctionelle de R. grandis est influencée par plusieurs facteurs étroitement corrélés, la densité de proies, la densité de prédateurs, et la distribution des proies. En mesurant l’efficacité de prédation de R. grandis en termes de survie des larves et de taux de croissance, nous avons démontré l’influence sur leur développement du temps passé par les larves à blesser et à tuer leurs proies. Ce facteur est par ailleurs fortement dépendant de la proportion de larves malades, blessées ou en cours de mue au sein du système ;une proportion qui peut augmenter en réponse à une augmentation de la densité de proies, ou lorsque des adultes sont présents (ceux-ci blessent les proies mais ne les consomment pas entièrement). Enfin, nos tests suggèrent qu’il n’existe que peu de cannibalisme ou de compétition intraspécifique entre larves de R. grandis, tandis que des modes de compétition moins importants prennent vraisemblablement place.

R. grandis présente également une réponse numérique reproductive à la densité de proies disponibles, principalement basée sur la perception de stimuli et d’inhibiteurs présents dans les galeries du scolyte. Par la collecte de composés volatils présents dans ces systèmes à l’aide de fibres SPME, nous avons développé une méthode non-destructive pour suivre la dynamique de production des médiateurs chimiques. Nos tests ont démontré que l’activité des larves de D. micans ou D. valens influence fortement la dynamique de production de certains monoterpènes oxygénés. En revanche, il n’a pas été été possible de corréler les différents composés identifiés au nombre de larves de R. grandis présentes dans le système.

La problématique soulevée par la progression de D. micans, de même que les résultats détaillés de chacune des études décrites ci-dessus sont discutés dans les deux papiers publiés et les trois manuscrits formant cette thèse. Les différentes perspectives apportées par ce travail sont également présentées dans la discussion générale.

ENGLISH ABSTRACT: Lucerne is the most important pasture and fodder crop in the winter rainfall area of South Africa. Various pests are known to cause damage to this crop. The use of the sweep net for monitoring pests is a cheap, easy and quick technique. If the sweep net is suitable for the lucerne pests in South Africa, potential pest status can be determined easily and quickly and the necessary precautionary measures taken to prevent crop losses. From a managerial point of view, it is also important to know the composition of the insect community in order to follow practices in which the number of beneficial insects can be increased and the injurious insects decreased. Therefore a study was done to quantify the use of the sweep net as a survey technique for monitoring pests on established lucerne stands. Insect diversity was also determined to obtain information on the insect families and guilds on lucerne. The redlegged earth mite, due to its importance as a pest, and the Anystis mite, important as a predator, were also included. The sweep net proved to be suitable for the sampling of the main lucerne pests. If a 29 cm diameter sweep net is swiped once per pace for six long paces, twelve systematically chosen sampling units are recommended for the lucerne earth flea and aphids. It is not necessary to differentiate amongst the three aphid species, or between the winged and unwinged aphids. Actual counts should be used instead of absence-presence data. Instead of counting all the insects in a sample, sub-samples can be taken. Operational characteristic curves can be used to determine the risk involved in the decision not to intervene, for example by spraying or grazing. Recommendations for monitoring and the accuracy of control decisions for the redlegged earth mite, Sitona weevil and lucerne butterfly can only be made after threshold values have been determined. The pea aphid, bluegreen aphid and lucerne earth flea showed peaks in their population levels during spring. Peak numbers of the spotted alfalfa aphid occurred during late summer and autumn. The Sitona weevil and lucerne butterfly numbers reached peak levels during late spring and early summer. For all pests population levels were dramatically reduced after grazing or cutting of the plantings. Therefore, these cultivation practices provided good control. The herbivores made up more than 85% of the insect community in lucerne. The largest herbivorous families, in terms of the number of individuals per family, were the Aphididae and Sminthuridae. These two families contain the main lucerne pests, the pea aphid, bluegreen aphid, spotted alfalfa aphid and the lucerne earth flea. The largest predatory family was the Anystidae, represented by the Anystis mite, the most important predator of the red legged earth mite and lucerne earth flea. Another well represented predatory family was the Coccinellidae, containing natural enemies of the aphids. The dryland plantings had a higher percentage of predators than the irrigated lucerne. The most important parasitaids were those in the superfamily Chalcidoidea and in the family Braconidae. The main detritivores were springtails in the suborder Arthropleona, insects in the families Mycetophilidae on irrigated lucerne, and Mycetophagidae on dryland lucerne. The most abundant visitors were in the families Chironomidae, Drosophilidae and Tephritidae. The dryland plantings had a lower percentage of visitors than the irrigated plantings. The number of insect families, as well as the number of individuals per family, was lower at the dryland plantings than at the irrigated plantings. The vast majority of insect families found on lucerne were collected during the one-year sampling period. A lower diversity was found where grazing was more severe, and there was a negative relationship between diversity and evenness.
AFRIKAANSE OPSOMMING: Lusern is die belangrikste wei- en voergewas 10 die winterreëngebied van Suid- Afrika. Hierdie gewas word deur 'n verskeidenheid plae aangeval. Die gebruik van die swaainet vir die monitering van plae is 'n goedkoop, maklike en vinnige tegniek. lndien die swaainet geskik is vir die betrokke plae in Suid-Afrika, kan potensiële plaagstatus van die plae dus maklik en vinnig bepaal word en die nodige voorsorgmaatreëls getref word om verliese te voorkom. Vanuit 'n bestuursoogpunt is dit ook belangrik om te weet wat die samestelling van die insekgemeenskap is sodat praktyke gevolg kan word waardeur die getal voordelige insekte verhoog en nadelige insekte verlaag word. Gevolglik is 'n studie uitgevoer om die gebruik van die swaainet te kwantifiseer as 'n monsternemingsmetode vir die monitering van plae op gevestigde lusernstande. Insekdiversiteit is ook bepaal ten einde inligting te bekom oor die insekfamilies en -gildes op lusern. Die lusernerdvlooi en swartsandmyt, vanweë hul belang as plae, en die Anystis-roofmyt, vanweë sy belang as predator, is ook ingesluit. Die swaainet blyk geskik te wees vir die monitering van die. vernaamste lusernplae. Wanneer 'n 29 cm deursnee swaainet vir ses lang treë een keer per tree geswaai word, word 12 sistematies gekose steekproefnemingseenhede vir die lusernerdvlooi en plantluise aanbeveel. Daar hoef nie onderskeid tussen die plantluisspesies en tussen gevleuelde en ongevleuelde plantluise getref te word nie. Daar moet gebruik gemaak word van werklike insektellings en nie van aanwesigheid-afwesigheid data nie. In plaas van om al die insekte in 'n monster te tel, kan submonsters geneem word. Operasionele karakteristieke kurwes kan gebruik word om die risiko verbonde aan die besluit om nie op te tree, deur byvoorbeeld te spuit of bewei nie, te bepaal. Vir die swartsandmyt, Sitona-snuitkewer en lusernskoenlapper moet drempelwaardes eers vasgestel word voordat aanbevelings vir monitering en die akkuraatheid van besluite rakende beheer, gegee kan word. Vir die ertjieluis, blougroenluis en lusernerdvlooi het die bevolkingsvlakke 'n piek in die lente bereik. Die gevlekte lusernluis se piekgetalle was hoofsaaklik in die laat somer en herfs. Die Sitona-snuitkewer en lusernskoenlapper het piekgetalle gehad in die laat lente en vroeë somer. Vir al die plae het bevolkingspieke drasties afgeneem nadat die aanplantings bewei of gesny is. Hierdie verbouingspraktyke blyk dus goeie beheer te verskaf. Die herbivore op lusern het meer as 85% van die insekgemeenskap beslaan. Die grootste herbivoorfamilies, in terme van aantal individue per familie, was die Aphididae en Sminthuridae. Hierdie twee families bevat die vernaamste lusernplae, naamlik die ertjieluis, blougroenluis, gevlekte lusernluis en lusernerdvlooi. Die grootste predatoriese familie was die Anystidae, wat verteenwoordig is deur die Anystis-roofmyt. 'n belangrike predator van die swartsandmyt en lusernerdvlooi. Nog 'n predatoriese familie wat goed verteenwoordig was, was die Coccinellidae, natuurlike vyande van plantluise. Die droëland aanplantings het 'n hoër persentasie predatore gehad as die besproeide lusern. Die belangrikste parasitoïede aanwesig was dié in die superfamilie Chalcidoidea en familie Braconidae. Die vernaamste detritivore was erdvlooie in die suborde Arthropleona, insekte in die families Mycetophilidae by besproeide lusern, en Mycetophagidae by droëland lusern. Die volopste besoekers was lede van die families Chironomidae, Drosophilidae en Tephritidae. Die droëland aanplantings het 'n laer persentasie besoekers gehad as die besproeide lusern. Die aantal insekfamilies, asook die aantal individue per familie, was laer by die droëland aanplantings as by die besproeide aanplantings. Die oorgrote meerderheid insekfamilies wat op lusern voorkom, is gedurende die een jaar opnameperiode waargeneem. 'n Laer insekdiversiteit is gevind waar beweiding strawwer was, en daar was 'n negatiewe verband tussen diversiteit en gelykmatigheid.

Abstract:
AbstractAgricultural biodiversity plays a vital role in enhancing food security and human health. Sustainable agriculture practices that conserve soil and water can result in good environmental and human health. In view of this, a project on capacity-building for sustainable agricultural practices targeting extension officers was implemented between September 2017 and February 2021 in Kampong Cham Province, Cambodia, by the Institute of Environmental Rehabilitation and Conservation (ERECON), Japan. The project involved government agencies, educational institutes, NGOs, and farmers, and employed a multi-stakeholder approach to promote sustainable farming practices among local farmers and enable conditions for the sale of agricultural products with low chemical inputs, especially in a province where agrochemical application is prevalent. A questionnaire survey, key informant interviews, focus group discussions, and observations from farmers were used for programme monitoring. Farmers reported that soil quality was improved after applying compost, and more beneficial insects were found after integrated pest management techniques were applied. The amount of agrochemicals applied to farmlands decreased compared to usage before the project start, implying that the project was successful in promoting sustainable agriculture in the province. During the COVID-19 pandemic, communities in the project areas are struggling to cope with food and health insecurity. The intervention has helped communities become more resilient during this hard time. After 3 years, many of the approximate 1500 farmers involved in the project are applying organic fertilisers and enhancing agricultural biodiversity in their farmlands. This case is a grassroots-level activity, but the concept of multi-stakeholder activities for agricultural biodiversity conservation can be replicated in other areas of Cambodia for achieving the sustainable development goals.

The article introduces a study in the field of monitoring the number and density of the population of grape moth using pheromone traps. In the course of this research, we found that the grape moth in 2019 developed in three generations. On the night peak flight, the largest pest population in the first generation was 2–3 insects/day; in the third generation – 1 insect/day. The population density of the grape moth in the conditions of the Novocherkassk branch of the Experimental field did not exceed the economic threshold and during the development of three generations was low. Hence, protective measures were not carried out.

Abstract:
During summer 2019, pilot tests were conducted in the Eastern part of the Krasnodar Krai and in the North of the Voronezh Region on two volatile semiochemicals of maize (phenylacetaldehyde and 4-methoxy-2-phenethyl alcohol) to monitor the European corn borer Ostrinia nubilalis number in comparison with sex pheromones. Traps with semiochemical lure caught significantly more pest adults than traps with sex pheromone – in the Voronezh Region by 16.5 times, and in the Krasnodar Krai by 2.4 times. At the same time, about half of the moths attracted by semiochemical lure were females, whose information value for forecasting is significantly higher than that of males. The results obtained indicate that semiochemical lure can be used for monitoring pests, especially in the Northern foci of its harm, where traps with sex pheromones cannot provide reliable monitoring of the insect

Abstract:
Sunflower is one of the strategic crops in the Krasnodar Territory. The lack of timely monitoring, the widespread and repeated use of chemical insecticides has led to pests resistance to them. This situation creates a need for new methods of monitoring and protecting the crops from economically significant insects. The purpose of these studies was to identify the effectiveness of LED traps for monitoring and controlling Helicoverpa armigera. The paper presents a comparative analysis of captured insects using aspiration and conical traps. The dynamics of captured insects and the possibility of using these devices as a means of monitoring and reducing the number of cotton scoops are shown.

Abstract:
The study aim was to identify the impact of the major defoliator pests of oaks, in correlation with the main oaks phenological phenomena and the development of various pests stages, to better understand the vitality of forest ecosystems, the causes and effects of stress factors. It was determined that the most aggressive pests of oaks in the studied stands were on the leaves: insects of fam.Cynipidae, Totrix viridana, Erannis defoliaria, Operophtera rumata, Tischeria complanella, insects of fam.Argidae; and on the fruit - Balaninus glandium. The actions of the insects were directly dependent on abiotic and biotic factors. The use of pheromone traps has proved to be an effective method in monitoring the pests of the investigated stands and has allowed the determination of outbreaks for the development of sp.Totrix viridana and Lymantria dispar. During the growing season, through crown defoliation, trees have gone from healthy tree to moderate and severe ones. The study suggests the need to develop effective strategies and measures to protect forests in the face of environmental changes.
