Streszczenie:
Literature concerning interactions between herbicides and insects is reviewed. Herbicides can be toxic to insects or can affect them indirectly, such as by destroying food supplies, but they usually can be used with proper application timing without affecting insects adversely. Herbicides and biocontrol insects can interact either favorably or unfavorably depending on the life cycle stage of weed and insect, effect on predatory insects, changes in food quality, mobility of the biocontrol insect, and impact of herbicides on weed growth. Thus, interactions between a biocontrol insect and herbicide can be antagonistic, additive, complementary, or synergistic. Split-plot techniques to evaluate these interactions at an early stage of insect establishment are proposed to improve weed biocontrol.

Streszczenie:
A butterfly's fore- and hindwings act as one low aspect ratio wing. The variation in the feathering angle is not as large as that of other insects such as a dragonfly and a damselfly. A butterfly varies the lead-lag angle of the forewing and the angle between the thorax and the abdomen at take-off. This implies the possibility that the insect moves all parts of its body to fly. This is an advantage that an insect has over a conventional aircraft. Moreover, a new method to investigate an insect’s flight control ability is introduced. An attached plate disturbs the insect, and a remarkable flight pattern can be observed. The flight control ability of the insect can be elucidated by analyzing the insect’s flight pattern.

Streszczenie:
Economically important insects include pests of plants, animals and stored products as well as insects produced commercially (honey bees, silkworms, insects for fish bait and food for birds and zoo animals). Other insects are produced in large numbers for experimental purposes, biological control of insect pests and weeds and the production of sterile insects for population suppression. Insect viruses may affect morphology, physiology and behavior, often reducing longevity and reproductive potential. Thus insect viruses can be used as biological control agents of pest insects. Insect viruses may also interfere with the production or function of biological control agents (e.g., parasitoids and predators) and insects used for research purposes. Therefore, it is advantageous to screen commercial and research colonies and imported insects for viruses.Electron microscopy of negatively stained specimens (NS EM) offers a relatively rapid and inexpensive means of screening populations of insects for the presence of viruses or viruslike particles and to monitor the progress of virus control programs.

Insect infestation of plant material is a serious problem to the greenhouse industry. Nonpesticidal destruction of insects on plant material before they are placed in the greenhouse would supply producers and growers with pest-free plant materials and decrease pesticide usage and exposure of workers and the environment to chemical insecticides. The efficacy of vacuum treating chrysanthemum (Chrysanthemum morifolium) and poinsettia (Euphorbia pulcherrima) plants for the reduction of insect pests (aphids and greenhouse whiteflies) was investigated. The effects of surfactants on insect elimination was determined. Properly controlled vacuum treatment in conjunction with surfactants was found to disrupt the physical integrity of the insects in all stages of their life cycle.

This review examines the hidden world of plant-insect interactions by emphasizing on the sensory perception and behavior of phytophagous insects, nutritional influence on insect reproduction, host plant resistance, Insects, weed and crop interaction, Insect pollinator plant interaction, tri-trophic interaction, and insect biotechnology. It explores how insects use sensory cues to forage for food, find mates, perceive dangers, and navigate their environment. It also examines the influence of host plants on insect behavior and the use of chemical cues for communication. The potential use of semio-chemicals in pest management for sustainable agriculture is highlighted. Nutritional factors and their impact on insect reproductive success are also discussed, emphasizing the need for balanced diets. The different categories of host plant resistance and their effects on insects are examined. The interdependent relationships between insects, plants, and weeds in agricultural ecosystems are explored, with a focus on the role of insect pollinators. The decline of insect pollinators and the importance of studying them are emphasized. The importance of tri-trophic interactions in maintaining ecological balance and biodiversity is discussed. Moreover, the role of biotechnological techniques like genomics, proteomics, transcriptomics, and epigenetics in understanding insect plant interactions as well as developing insect pest control strategies is discussed. The potential use of natural products produced by plants in environmentally friendly pest control methods is also examined. Overall, this review provides a comprehensive exploration of insect-plant interactions and the potential for sustainable pest control methods.

Abstract Reliance on broad-spectrum insecticides and chemotherapeutic agents to control hematophagous insect vectors, and their related diseases is threatened by increasing insecticide and drug resistance, respectively. Thus, development of novel, alternative, complementary and effective technologies for surveillance and control of such insects is strongly encouraged. Semiochemicals are increasingly developed for monitoring and intervention of insect crop pests, but this has not been adequately addressed for hematophagous insects of medical and veterinary importance. This review provides an insight in the application of semiochemicals for control of hematophagous insects. Here, we provide specific information regarding the isolation and identification of semiochemical compounds, optimization approaches, detection, perception and discrimination by the insect olfactory system. Navigation of insects along wind-borne odor plumes is discussed and methods of odor application in field situations are reviewed. Finally, we discuss prospects and future challenges for the application of semiochemical-based tools with emphasis on mosquitoes. The acquired knowledge can guide development of more effective components of integrated vector management, safeguard against emerging resistance of insects to existing insecticides and reduce the burden of vector-borne diseases.

Insects were collected from rice fields in Karawang West Java. Since insects are dominant in Rice field, their role in the ecosystem are important regarding the rice production. Therefore, the occurance of insect species and their role in ecosystem are important to understand. The aim of this reasearch was to study the insect occurance in rice field in Karawang to obtain the potential candidate for biological control agent. The insects were collected using sweep net, pit fall trap and light trap. Nine insect orders were collected and 49 morphospecies were identified including insect pest, parasitoids, predator, tourist and detritivore. Paederus sp., Cyrtohinus and Micraspis sp., were the most abundant entomophagous insect that is potential candidate for biological control agent in Karawang.

Abstract COMPARATIVE EFFICACY OF CONVENTIONAL VERSUS CONTROLLED-DROPLET APPLICATION, 1986: Potato seed pieces were planted in a Rhinebeck silt loam field on 3 Jun at the Cornell Vegetable Research Farm, Freeville, N.Y. Each plot consisted of a 30-ft-long row separated by 2 skipped rows. Plots were arranged in a split-plot experimental design with 4 replications. Treatments were applied with a tractor-mounted hydraulic boom sprayer with 4 hollow-cone nozzles delivering 100 gal/acre at 130 psi and with a tractor-mounted controlled-droplet-applicator (CDA) sprayer delivering 5.3 gal/acre at 3500 rpm and 20 psi. Treatments were applied on 4 Jul and 4 Aug. Sampling methods and dates were (1) Colorado potato beetle (CPB): number of live beetles/10 hills on 3, 5, and 7 Jul; number of live larvae/10 mainstems on 11, 18, and 25 Jul; (2) aphids: number/5 compound leaves (from lower third of plant) on 1, 5, 11, and 18 Aug; and (3) potato leafhopper (PLH): number/5 D-vac sampling sites on 1, 5, 11, and 18 Aug. Weed control, fertilization, and other cultural practices were the same as those normally used in commercial production.

Streszczenie:

This thesis describes the synthetic preparation of somecompounds, which can serve as chemical signals for use in thedevelopment of control methods for pest insects. The compoundssynthesised are of the isoprenoid type and of two kinds:carvone derivatives and germacranes. The derivatives of carvoneare based on modifications of this compound, by reactions ofeither its endocyclic or its exocyclic double bond. One type ofmodifications was accomplished by chemoselective additions ofthiophenol. The latter ones imply additions to the exocyclicdouble bond and seem to constitute general, previously rarelystudied reactions.

In other modifications of its exocyclic side chain, carvoneafforded some sesqui- and diterpeniod natural products. Thefollowing compounds were synthesised in an enantioselectiveway: (-)-epi-delobanone, (-)-delobanone,(-)-7-hydroxy-3,10-prenylbisaboladien- 2-one (an insecticidalconstituent of Croton linearis) as well as its diastereomer andsome other compounds with similar structures. All of thesecompounds weretested for their antifeedant/feeding deterrentcapability against gnawing of the pine weevil, Hylobiusabietis.

The germacranes prepared by means of enantioselective totalsyntheses are: (–)- 1(10),5-germacradien-4-ol and(–)-germacrene D. The former is a constituent of thedefence secretion (an allomone) from the larvae of the pinesawfly, and the needles of Scots pine. (–)-Germacrene D isa ubiquitous compound in nature. For example, it occurs in thepeels of apples and acts as one component of a lure (akairomone) to the apples, which attracts the codling moth,Cydia pomonella.

The main problem in the total syntheses of the germacraneswas the formation of the unsaturated monocyclic 10-memberedring. This was achieved by intramolecular alkylation with asuitably functionalised/protected cyanohydrin derivative,which, after further elaboration, afforded a monocyclic10-membered enone, that was used in the syntheses of the twogermacranes mentioned above. In the initial steps in thesynthetic sequence the stereochemistry was established byalkylation of an amide enolate attached to a chiral auxiliary.This approach could most likely also readily furnish the(+)-enantiomers of these germacrenes (of the germacraneterpenoid class) using the opposite enantiomer of the chiralauxiliary in the initial steps.

Keywords: isoprenoids, natural product synthesis,allelochemicals, kairomones, allomones, bisabolane terpenoids,Hylobius abietis, germacrane terpenoids, Neodiprion sertifer,stereoselective synthesis.

Management of whiteflies with two insect growth regulators was compared with standard practices in grower managed cotton near Gila Bend, AZ. The IGRs, Knack (pyriproxyfen) and Applaud (buprofezin) were tested in a randomized complete block experiment with seven replicates. University ofArizona recommendations were followed to time insecticide applications. Following IGR applications, the nymphal populations remained near or below action thresholds (≤ 0.5-1.0 large nymphs per 3.88 cm² disk) from early August through early October. The standard practices treatments maintained the nymphal population through only early September, when populations sharply increased IGR treatments resulted in adult populations below University of Arizona action thresholds nearly as long as the nymphs. There was an adult population peak that followed a nymphal peak near the middle of September.

Streszczenie:
The burden of many vector-borne diseases remains high and for some, such as dengue fever, continues to rise. It is estimated that up to half of the global population is at risk from dengue. Treatment of dengue fever is currently limited to case management and there are, at present, no licensed vaccines available. As a result, the front-line defence against dengue fever remains vector control. Modern approaches to vector control are attempting to push forward new techniques to target the mosquito vectors of dengue. One such technique is the release of transgenic insects that are genetically sterile due to a conditional dominant lethal gene. This modern adaptation of the traditional sterile insect technique is at the forefront of current new vector control solutions. The success of a vector control effort using releases of transgenic insects relies on the technology being efficacious as well as effective in the field. To ensure the effectiveness of field-released sterile insects a deep knowledge of the mosquito biology and ecology must be combined with site-specific, logistical and cost considerations. In order to maximise the potential of this technology the field releases of these insects must be optimised. This work includes a specific focus on the exploration of the dynamics of releasing different life stages, investigations into the biology and ecology of the released insects and the development of applied methodology relating to the release and monitoring of transgenic insects. Novel vector control techniques, such as the use of transgenic insects, have an important role to play in addressing the emergence and spread of dengue fever. In order to utilise these technologies to their full potential they must be optimised to maximise their effectiveness. In this thesis I present work towards this optimisation.

Streszczenie:
Insects are common in our world, such as ants, spiders, cockroaches etc. Virtual representations of them have wide applications in Virtual Reality (VR), video games and films. Compared with the large volume of works in biped animation, the problem of insect animation was less explored. Their small body parts, complex structures and high-speed movements challenge the standard techniques of motion synthesis. This thesis addressed the aforementioned challenge by presenting a framework to efficiently automate the modelling and authoring of insect locomotion. This framework is inspired by two key observations of real insects: fixed gait pattern and distributed neural system. At the top level, a Triangle Placement Engine (TPE) is modelled based on the double-tripod gait pattern of insects, and determines the location and orientation of insect foot contacts, given various user inputs. At the low level, a Central Pattern Generator (CPG) controller actuates individual joints by mimicking the distributed neural system of insects. A Controller Look-Up Table (CLUT) translates the high-level commands from the TPE into the low-level control parameters of the CPG. In addition, a novel strategy is introduced to determine when legs start to swing. During high-speed movements, the swing mode is triggered when the Centre of Mass (COM) steps outside the Supporting Triangle. However, this simplified mechanism is not sufficient to produce the gait variations when insects are moving at slow speed. The proposed strategy handles the case of slow speed by considering four independent factors, including the relative distance to the extreme poses, the stance period, the relative distance to the neighbouring legs, the load information etc. This strategy is able to avoid the issues of collisions between legs or over stretching of leg joints, which are produced by conventional methods. The framework developed in this thesis allows sufficient control and seamlessly fits into the existing pipeline of animation production. With this framework, animators can model the motion of a single insect in an intuitive way by specifying the walking path, terrains, speed etc. The success of this framework proves that the introduction of biological components could synthesise the insect animation in a naturalness and interactive fashion.

The 1985 and 1986 Cotton Reports have the same publication and P-Series numbers.
Cotton was treated at the pinhead square stage with Orthene to prevent boll shed caused by thrips and Lygus. Yield results showed no statistically significant differences, even though yield trends indicated a decrease in the treated plots compared to the check. Severe pressure from Heliothus later in the season and the yield trends would indicate that the insecticide treatment effect on the beneficial insects was more important than its effect on thrips and Lygus.

Abstract This chapter discusses the environmental impact of insect rearing. Direct greenhouse gas (GHG) emissions from insects used as feed or food are discussed and data from life cycle assessments (LCAs) on commercially farmed insects are discussed per species. The relevance of the utilized feed on the environmental impact of insects and their derived products, including suggestions to lower this impact are also discussed. It is concluded that land use associated with insect production generally seems low, compared to conventional feed and food products. The EU (expressed as fossil fuel depletion) of insect production is often high compared to conventional products. To a large extent this is because several LCAs have been conducted for systems in temperate climates, which require extensive climate control.

This work describes the intimate fusion of microsystems and physiology though the partial implantation of a microfluidic device into living insects, Manduca Sexta moth. This effort is a critical component in our development of “Insect-Micro Air Vehicles (I-MAVs)” which aim to fuse nanodevice technology with living organism. The specific goal of this system is to provide “on-command” chemically induced immobilization and subsequent reanimation of the otherwise autonomous insect by implanting a low power electrokinetic drug delivery device. In this paper, we demonstrate the locomotor activity control by releasing neurotransmitters into wing muscles. We also provide results of our fully functioning adult survivability data for pupal stage implanted microdevices along with results from a comprehensive study of a low power electroactive drug delivery system.

Insect flight has gained wide interests in both biology and engineering communities in the past decades regarding its aerodynamics, sensing and flight control. However, studying insect flight experimentally remains a challenge in both free-flight and tethered-flight settings. In free flight experiments, due to highly unpredictable and fast flight behavior of flying insects, it is difficult to apply controlled sensory inputs to their flight system for system identification and modeling analyses. In tethered flight experiments, constrained whole body movement results in silenced proprioceptive feedback therefore breaks the flight control loop and does not reveal any flight dynamics. Therefore, this work aims to develop a novel insect tether system using magnetic levitation. Such a system magnetically fixes an insect in space but allows it to rotate freely about yaw axis with minimal interference from mechanical constraints. This paper presents the development, analysis and feedback control of this system and finally test its performance using a hawkmoth (Manduca Sexta). In addition, a system identification of the magnetic levitation system and detailed analysis in closed-loop stability and performance are provided. In the future, the insect tether system will be applied to study the insect flight aerodynamics, sensing and control.

Over the past decade, the potential of edible insects as a novel food ingredient in high value-added products has been investigated to find alternatives to conventional animal protein sources that are over-exploited and harmful to the environment. One of the most challenge for the edile insect industry is to improve the consumer acceptability for this non conventional food matrix. Although there are many complex factors that influence the consumers' perceptions and acceptability of insects as food, it is well-documented that insect-based foods in which insects were not visible to the consumer created less aversion, highlighting the importance of developing products with processed insects. In this context, the development of edible insect ingredients, from meal until insect protein isolate, is currently largely studied. More specifically, and because these ingredients are composed of a high amount of proteins, this macronutrient is of specific significance. In this context, edible insect proteins represent a great opportunity for the development of the edible insect industry due to their interesting nutritional aspect and bioactive properties. However, for the development of edible insect-based food for human consumption, it become necessary to control the impact of conventional and emerging food processing on the insect protein structures and techno-functional properties. Simultaneously, it is crucial to ensure that the insect-based food products generated after the different processing steps are safe for the consumer, mainly in terms of microbial contaminations and allergenicity. Consequently, and regarding the different points indicated above, this presentation will highlight the different opportunities and challenges regarding the development of insect protein-rich food ingredients.

The article briefly discusses the available and existing methods of control of insects-pests of grain reserves and food products. The author concludes about the preferences of the grain reserves irradiation by ionizing radiation. The author points out that to actual date, have been experimentally determined such doses of ionizing radiation, which sterilize or kill the most common insect pests. However, the data obtained are still not enough to organize a wide and comprehensive application of ionizing radiation in pest control. Therefore, it is necessary to conduct further in-depth and comprehensive experimental studies of the sensitivity of all types of insect pests to ionizing radiation in order to justify the optimal conditions and modes of irradiation of agricultural and food products. Accumulation of experimental material will allow to study more deeply the reasons and mechanisms of infringement of vital functions of an organism of insects-wreckers under the influence of ionizing radiation, and, thereby, to provide successful fight against these wreckers of stocks.

The restricted host range of many baculoviruses, highly pathogenic to Lepidoptera and non-pathogenic to mammals, limits their use to single or few closely related Lepidopteran species and is an obstacle to extending their implementation for pest control. The insect immune response is a major determinant of the ability of an insect pathogen to efficiently multiply and propagate. We have developed an original model system to study the Lepidopteran antiviral immune response based on Spodoptera littoralis resistance to AcMNPV (Autographa californica multiple nucleopolyhedrovirus) infection and the fascinating immunosuppressive activity of polydnaviruses .Our aim is to elucidate the mechanisms through which the immunosuppressive insect polydnaviruses promote replication of pathogenic baculoviruses in lepidopteran hosts that are mildly or non-permissive to virus- replication. In this study we : 1- Assessed the extent to which and the mechanisms whereby the immunosuppressive Campoletis sonorensis polydnavirus (CsV) or its genes enhanced replication of a well-characterized pathogenic baculovirus AcMNPV, in polydnavirus-immunosuppressedH. zea and S. littoralis insects and S. littoralis cells, hosts that are mildly or non-permissive to AcMNPV. 2- Identified CsV genes involved in the above immunosuppression (e.g. inhibiting cellular encapsulation and disrupting humoral immunity). We showed that: 1. S. littoralis larvae mount an immune response against a baculovirus infection. 2. Immunosuppression of an insect pest improves the ability of a viral pathogen, the baculovirus AcMNPV, to infect the pest. 3. For the first time two PDV-specific genes of the vankyrin and cystein rich-motif families involved in immunosuppression of the host, namely Pvank1 and Hv1.1 respectively, enhanced the efficacy of an insect pathogen toward a semipermissive pest. 4. Pvank1 inhibits apoptosis of Spodopteran cells elucidating one functional aspect of PDVvankyrins. 5. That Pvank-1 and Hv1.1 do not show cooperative effect in S. littoralis when co-expressed during AcMNPV infection. Our results pave the way to developing novel means for pest control, including baculoviruses, that rely upon suppressing host immune systems by strategically weakening insect defenses to improve pathogen (i.e. biocontrol agent) infection and virulence. Also, we expect that the above result will help to develop systems for enhanced insect control that may ultimately help to reduce transmission of insect vectored diseases of humans, animals and plants as well as provide mechanisms for suppression of insect populations that damage crop plants by direct feeding.

Our original aims were to elucidate the mechanisms through which the immunosuppressive insect virus, the Campoletis sonorensis polydnavirus (CsV) promotes replication of a well-characterized pathogenic virus, the Autographa californica multiple nucleopolyhedrovirus (AcMNPV) in hosts that are mildly or non-permissive to virus replication. According to the BARD panels criticism we modified our short-term goals (see below). Thus, in this feasibility study (one-year funding) we aimed to show that: 1. S. littoralis larvae mount an immune response against a baculovirus infection. 2. Immunosuppression of an insect pest improves the ability of a viral pathogen (a baculovirus) to infect the pest. 3. S. littoralis cells constitute an efficient tool to study some aspects of the anti- viral immune response. We achieved the above objectives by: 1. Finding melanized viral foci upon following the baculoviral infection in S . littoralis larvae infected with a polyhedra - positive AcMNPV recombinant that expressed the GFP gene under the control of the Drosophila heat shock promoter. 2. Studying the effect of AcMNPV-infection in S . littoralis immunosuppressed by parasitation with the Braconidae wasp Chelonus inanitus that bears the CiV polydna virus, that resulted in higher susceptibility of S. littoralis to AcMNPV- infection. 3. Proving that S. littoralis hemocytes resist AcMNPV -infection. 4. Defining SL2 as a granulocyte-like cell line and demonstrating that as littoralis hemocytic cell line undergoes apoptosis upon AcMNPV -infection. 5. Showing that some of the recombinant AcMNPV expressing the immuno-suppressive polydna virus CsV- vankyrin genes inhibit baculoviral-induced lysis of SL2 cells. This information paves the way to elucidate the mechanisms through which the immuno- suppressive polydna insect viruses promote replication of pathogenic baculoviruses in lepidopteran hosts that are mildly or non-permissive to virus- replication by: - Assessing the extent to which and the mechanisms whereby the immunosuppressive viruses, CiV and CsV or their genes enhance AcMNPV replication in polydnavirus- immunosuppressed H. zea and S. littoralis insects and S. littoralis cells. - Identifying CiV and CsV genes involved in the above immunosuppression (e.g. inhibiting cellular encapsulation and disrupting humoral immunity). This study will provide insight to the molecular mechanisms of viral pathogenesis and improve our understanding of insect immunity. This knowledge is of fundamental importance to controlling insect vectored diseases of humans, animals and plants and essential to developing novel means for pest control (including baculoviruses) that strategically weaken insect defenses to improve pathogen (i.e. biocontrol agent) infection and virulence.

Toward development of spiroplasmas as novel toxin-delivery systems for biocontrol of beetle pests in the United States (Leptinotarsa decemlineata) and Israel (Maladera matrida), media for cultivating beetle-associated spiroplasmas were improved and surveys of these spiroplasmas were conducted to provide transformable strains. Extensive surveys of spiroplasmas yielded promising extrachromosomal elements for vector constructs. One, plasmid pCT-1, was cloned, characterized, and used as a source of spiroplasma origin of replication in our shuttle vectors. The fibrillin gene was isolated and sequenced and its strong promoter was also used in the constructs. Means for transforming these vectors into spiroplasmas were developed and optimized, with electroporation found to be suitable for most applications. Development and optimization of means for using large unilamellar vesicles (LUVs) in spiroplasma transformation represents a breakthrough that should facilitate insertion of large clusters of virulence genes. With completion of the vector, we should thus be poised to genetically engineer spiroplasmas with genes that will express toxins lethal to our target beetles, thus providing an effective and inexpensive alternative to conventional means of beetle control.

Learning from Nature How to Design Anti-insect Selective Pesticides - Clarification of the Interacting Face between Insecticidal Toxins and their Na-channel Receptors.

Structural details on the interacting faces of toxins and sodium channels (Navs), and particularly identification of elements that confer specificity for insects, are difficult to approach and require suitable experimental systems. Therefore, natural toxins capable of differential recognition of insect and mammalian Navs are valuable leads for design of selective compounds in insect control. We have characterized several scorpion toxins that vary in preference for insect and mammalian Navs, and identified residues important for their action. However, despite many efforts worldwide, only little is known about the receptor sites of these toxins, and particularly on differences between these sites on insect and mammalian Navs. Another problem arises from the massive overuse of chemical insecticides, which increases resistance buildup among various insect pests. A possible solution to this problem is to combine different insecticidal compounds, especially those that provide synergic effects. Our recent finding that combinations of insecticidal receptor site-3 toxins (sea anemone and scorpion alpha) with scorpion beta toxins or their truncated derivatives are synergic in toxicity to insects is therefore timely and strongly supports this approach. Our ability to produce toxins and various Navs in recombinant forms, enable thorough analysis and structural manipulations of both toxins and receptors. On this basis we propose to (1) restrict by mutagenesis the activity of insecticidal scorpion -toxins and sea anemone toxins to insects, and clarify the molecular basis of their synergic toxicity with antiinsect selective -toxins; (2) identify Nav elements that interact with scorpion alpha and sea anemone toxins and those that determine toxin selectivity to insects; (3) determine toxin-channel pairwise side-chain interactions by thermodynamic mutant cycle analysis using our large collection of mutant -toxins and Nav mutants identified in aim 2; (4) clarify the mode of interaction of truncated -toxins with insect Navs, and elucidate how they enhance the activity of insecticidal site-3 toxins. This research may lead to rational design of novel anti-insect peptidomimetics with minimal impact on human health and the environment, and will establish the grounds for a new strategy in insect pest control, whereby a combination of allosterically interacting compounds increase insecticidal action and reduce risks of resistance buildup.

The overall objective of our research was to develop methods to match species of entomopathogenic nematodes against the insect pests which they would be best adapted to control. The underlying hypothesis for this work was that entomopathogenic nematodes should be most effective when used against insect species to which they are naturally adapted to parasitize. Toward this end, we undertook a number of related studies focusing primarily on nematode foraging strategies. We found that foraging strategies affected host associations directly and indirectly. Nematodes' responses to host cues, and the role of their sensory organs based on lectin binding, led to new approaches to determining host range for these parasites. Based on this work, we developed a laboratory bioassay of host recognition behavior designed to predict field results. We also determined that nematodes that forage in a stationary manner (ambushers) have a slower metabolic rate than do active forgers (cruisers), thus their infective stage juveniles are longer lived. This study helps predict the duration of field activity after application and may partially explain field distributions of natural populations of entomopathogenic nematodes. The common thread linking all of these studies was that they led to a deeper understanding of the associations between entomopathogenic nematodes and insects as hosts.

A major consideration in the development of biopesticides based on entomopathogenic fungi has been the virulence and pathogenicity in terms of mean time of mortality and mean lethal concentration against the target insect. Virulence factors as chitinases degrade insect chitin facilitating the hyphal penetration through the cuticle. In this sense, Beauveria bassiana chitinases are an important cuticle-degrading group of enzymes implicated in the pathogenesis to insects, with high potential to develop biotechnological tools for in pest control. The aim of this study was to characterize chitinases produced by a Colombian strain of B. bassiana (Bv062) isolated from a Diatraea sp. larvae naturally infected in a sugar cane crop.
