Abstract:
Abstract When E.F. Knipling conceived of the release of sexually sterile insects to suppress wild populations, he laid down several fundamental qualities that characterized suitable target species—some of which mosquitoes generally violate—including high reproductive rates and large population numbers. Regardless of this, their global importance in public health has led numerous research teams to attempt to use the mosquito sterile insect technique against several species. Because of the degree of financial commitment required for suppression programs, most releases have consisted of preliminary investigations of male performance, population characteristics, and production methods. Those that have accomplished suppression provide important insights regarding the challenges of production, dispersal, and immigration. Insights gained from these studies remain relevant today, regardless of the genetic control technology being applied. In this article, I highlight studies that were notable for the insights that were gained, the intrinsic difficulties that mosquitoes present, and synthesize these into recommendations for successful applications of the sterile insect technique and newer technologies to mosquitoes.

Abstract:
Sterile insect releases to manage or eradicate pests have been deployed increasingly in many countries against diverse targets but have not previously been seriously considered in New Zealand The increasing cost of incursions of exotic species warrants a reconsideration of the potential for any approach that can help to defend New Zealand The success of the sterile insect technique is dependent on adequate understanding of pest biology techniques for mass rearing of sufficient numbers to overcome the target population mass sterility (with excellent quality assurance) competitive fitness of released insects and release systems that ensure effective spatial targeting Legislative hurdles such as the HSNO Act (1996) may need attention to enable this approach for insects that have arrived after 1998 The first use of the sterile insect technique in New Zealand is against the painted apple moth and is a useful case study to demonstrate the potential of the approach in biosecurity

Abstract:
We study simple mathematical models for the dynamics of interactive wild and sterile insect populations. As well as being mathematically tractable, these models can be used as first approximations to real situations occurring with the Sterile Insect Technique (SIT) in which sterile males are released to reduce or eradicate a pest population. This is a method of biological control which can effectively help contain the spread of many pest insects such as the Red Palm Weevil (RPW). Models formulated in this paper are continuous-time, include a strong Allee effect that captures extinction events, and incorporate different strategies of releasing sterile insects. We perform basic studies of dynamical features of these models, with an emphasis on the condition of excitation, and the impact of the different release methods is investigated. Our findings are also demonstrated with some numerical examples.

Abstract:
We study a simple mathematical model describing the dynamics of a wild-type pest insects population experiencing competition from sterile insects (one-sided competition). This model can be used for conceiving control strategies based on the Sterile Insect Technique (SIT) or the Incompatible Insect Technique (IIT), aiming to reduce or eradicate Red Palm Weevil (RPW) populations in some target regions. We show that suppression may occur for continuous and periodic release strategies for various intraspecific and interspecific submodels except in the case of a single release strategy where a strong Allee effect is required.

Abstract:
Although most insect species have a beneficial role in the ecosystems, some of them represent major plant pests and disease vectors for livestock and humans. During the last six–seven decades, the sterile insect technique (SIT) has been used as part of area-wide integrated pest management strategies to suppress, contain, locally eradicate or prevent the (re)invasion of insect pest populations and disease vectors worldwide. This Special Issue on “Sterile insect technique (SIT) and its applications”, which consists of 27 manuscripts (7 reviews and 20 original research articles), provides an update on the research and development efforts in this area. The manuscripts report on all the different components of the SIT package including mass-rearing, development of genetic sexing strains, irradiation, quality control as well as field trials.

Abstract:
The false codling moth (FCM), Thaumatotibia leucotreta (Meyrick) (Lepidoptera: Tortricidae), is an important pest of citrus in South Africa and challenging to manage due to its inconspicuous nature. An effective method currently being employed for the area-wide suppression of the FCM is the Sterile Insect Technique (SIT) and the effective dispersal of sterile moths is very important for success with SIT. This study was conducted in the Addo area of the Sundays River Valley (Eastern Cape) where the programme is commercially used. In this study, sterile male moths were released in different orchards on a citrus farm, and in nearby veld at different times of the year, and their dispersal was monitored through the use of pheromone traps. Various climatic factors were monitored. This provided insight into the local dispersal of sterile male FCM adults in response to abiotic cues (particularly climatic factors). The movement of the FCM in four citrus cultivars, namely lemons, navel and Valencia oranges and mandarins and in the nearby veld (open field), was determined at six different stages of the year. Results clearly indicated that sterile FCM movement is concentrated within citrus orchards, as very few moths were trapped beyond 30 m from the release point, particularly in navel and Valencia orchards. Of the climatic factors measured, minimum and maximum temperatures had the most significant influence on FCM dispersal, and based on the results, various recommendations are made for the releases of sterile FCM in an area-wide SIT management programmes on citrus. A better understanding of the dispersal capabilities of the FCM in an agricultural system, under different conditions and at different times of the year, is invaluable not only in improving release strategies in an SIT programme but in planning future control strategies against the FCM.

Abstract:
The tomato leafminer Liriomyza bryoniae (Kaltenbach) (Diptera: Agromyzidae) is an economically important pest of greenhouse tomato crops in the UK, which at high infestations can reduce the value of the crop by up to 20% . Sterile insect technique, SIT, is the release of sterile insects to overflood and mate with the pest population. Wild females that mate with sterile males lay eggs that contain dominant lethal mutations and are unable to develop into larvae. SIT has been proposed as a novel, alternative method of L.bryoniae pest suppression that could be used in conjunction with the current biological controls, such as Diglyphus isaea (Walker) (Hymenoptera: Eulophidae). This thesis presents information on the development of SIT against L.bryoniae and examines the feasibility and compatibility with existing pest management methods. Work was carried out that determined high quality, sterile adult L.bryoniae were produced when late stage pupae were irradiated with a dose of 160 Gy gamma radiation. Both male and female L.bryoniae were sterile after irradiation with 160 Gy, which is important given the current inability to separate pupae by sex. A multi-treatment cage experiment was used to compare bi-sex and male-only releases and showed that the release of sterile females did not have a detrimental effect and did not add to the pest problem. The multi-treatment cage experiment also compared the use of D.isaea with sterile male releases both separately and concurrently. Whilst the study conditions favoured the optimal environment for D.isaea oviposition and development, the concurrent release of sterile male L.bryoniae and D.isaea were compatible. SIT is a suitable method for L.bryoniae suppression; but further work to develop a more time and cost-efficient mass-rearing technique and greater knowledge of the market are required in order for it to become a financially viable pest management option. Overall, the irradiation of L.bryoniae pupae with 160 Gy produced sterile adults that have comparable fitness to wild-type adults, do not produce viable offspring and have the potential to suppress a L.bryoniae infestation.

ENGLISH ABSTRACT: Two mathematical models are formulated in this dissertation for the population growth of an Eldana saccharina Walker infestation of sugarcane under the influence of partially sterile released insects. The first model describes the population growth of and interaction between normal and sterile E. saccharina moths in a temporally variable, but spatially homogeneous environment. The model consists of a deterministic system of difference equations subject to strictly positive initial data. The primary objective of this model is to determine suitable parameters in terms of which the above population growth and interaction may be quantified and according to which E. saccharina infestation levels and the associated sugarcane damage may be measured. The second model describes this growth and interaction under the influence of partially sterile insects which are released in a temporally variable and spatially heterogeneous environment. The model consists of a discretized reaction-diffusion system with variable diffusion coefficients, subject to strictly positive initial data and zero-flux Neumann boundary conditions on a bounded spatial domain. The primary objectives in this case are to establish a model which may be used within an area-wide integrated pest management programme for E. saccharina in order to investigate the efficiency of different sterile moth release strategies in various scenarios without having to conduct formal field experiments, and to present guidelines by which release ratios, frequencies and distributions may be estimated that are expected to lead to suppression of the pest. In addition to the mathematical models formulated, two practical applications of the models are described. The first application is the development of a user-friendly simulation tool for simulating E. saccharina infestation under the influence of sterile insect releases over differently shaped spatial domains. This tool provides the reader with a deeper understanding as to what is involved in applying mathematical models, such as the two described in this dissertation, to real-life scenarios. In the second application, an optimal diversification of sugarcane habitats is considered as an option for minimising average E. saccharina infestation levels, and as a further consequence, improving the cost-efficiency of sterile insect releases. Although many special cases of the above model classes have been used to model the sterile insect technique in the past, few of these models describe the technique for Lepidopteran species with more than one life stage and where F1-sterility is relevant. In addition, none of these models consider the technique when fully sterile females and partially sterile males are being released. The models formulated in this dissertation are also the first to describe the technique applied specifically to E. saccharina, and to consider the economic viability of applying the technique to this species. Furthermore, very few examples exist of such models which go beyond a theoretical description and analysis towards practical, real-life applications as illustrated in this dissertation.
AFRIKAANSE OPSOMMING: Twee wiskundige modelle word in hierdie proefskrif vir die populasiegroei van ’n Eldana saccha- rina Walker infestasie van suikerriet onder die invloed van gedeeltelik steriele, vrygelate insekte daargestel. Die eerste model beskryf die populasiegroei van en -interaksie tussen normale en steriele E. saccharina motte in ’n dinamiese, maar ruimtelik-homogene omgewing. Die model is ’n stelsel deterministiese verskilvergelykings onderhewig aan streng positiewe aanvangswaardes. Die primˆere doelstelling met hierdie model is om geskikte parameters te bepaal in terme waarvan die bogenoemde groei en interaksie gekwantifiseer kan word, en waarvolgens E. saccharina infestasievlakke en die gepaardgaande suikerrietskade gemeet kan word. Die tweede model beskryf hierdie groei en interaksie onder die invloed van gedeeltelik steriele insekte wat in ’n dinamiese en ruimtelik-heterogene omgewing vrygelaat word. Die model is ’n gediskretiseerde stelsel reaksie-diffusievergelykings met veranderlike diffusieko¨effisi¨ente onderhewig aan streng positiewe aanvangswaardes en zero-vloei Neumann-randwaardes op ’n begrensde ruimtelike gebied. Die primˆere doelstellings in hierdie geval is om ’n model tot stand te bring wat in ’n area-wye, ge¨ıntegreerde pesbestrydingsprogram vir E. saccharina gebruik kan word om die doeltreffendheid van verskillende steriele motvrylatingstrategie¨e te bepaal sonder om daadwerklik veldeksperimente uit te voer, en om riglyne daar te stel waarvolgens vrylatingsverhoudings, -frekwensies en -verspreidings bepaal kan word wat na verwagting na ’n onderdrukking van die pes sal lei. Bykomend tot die wiskundige modelle in hierdie proefskrif, word twee praktiese toepassings van die modelle ook beskryf. In die eerste toepassing word ’n gebruikersvriendelike simulasie hulpmiddel ontwikkel om E. saccharina infestasie onder die invloed van steriele insekvrylatings in verskillende ruimtelike gebiede te simuleer. Hierdie toepassing fasiliteer ’n dieper begrip van wat ter sprake is in die toepassing van wiskundige modelle, soos die twee modelle in hierdie tesis, tot werklike scenario’s. In die tweede toepassing word ’n optimale diversifisering van suikerriet habitats as ’n opsie vir die vermindering van die gemiddelde E. saccharina infestasie vlakke beskou, en gevolglik word die verbetering van die koste-doeltreffendheid van steriele insekvrylatings afgeskat. Alhoewel verskeie spesiale gevalle van die bogenoemde twee klasse van modelle reeds in die verlede gebruik is om die doeltreffendheid van die steriele-insektegniek te modelleer, beskryf weinig van hierdie modelle die tegniek vir Lepidopteriese spesies met meer as een lewensfase en waar F1-steriliteit ter sprake is. Verder beskryf geen van hierdie modelle die tegniek waar algeheel steriele wyfies en gedeeltelik steriele mannetjies vrygelaat word nie. Die modelle in hierdie tesis is ook die eerste waar die tegniek spesifiek op E.saccharina toegepas word, en waar die ekonomiese lewensvatbaarheid van die tegniek vir hierdie spesie oorweeg word. Verder bestaan daar min voorbeelde van soortgelyke modelle wat verder gaan as ’n teoretiese beskrywing en wiskundige ontleding na praktiese, werklike toepassings, soos in hierdie proefskrif ge¨ıllustreer.

Abstract:
In the light of increasing pesticides resistance in agricultural pests and in insect vectors of human diseases, leading to the rise in occurrence of mosquito-borne diseases, new, efficient and environmentally friendly methods of pest control are needed. Sterile Insect Technique (SIT), relying on mass releases of radiation sterilised males to reduce reproductive potential of target pest populations, although not new, offers an alternative to the use of pesticides and is an environmentally non-polluting method of insect control. Many insect species, however, are not very amenable to classical SIT, due to detrimental side-effects of radiation treatment. We propose a new method, a genetically engineered modification of classical SIT, replacing radiation with genetically induced sterility. Based on conditional expression of male-germline targeted nucleases which introduce double strand breaks into the male germline DNA to render males sterile, this method emulates SIT mechanism, at the same time eliminating radiation and associated detrimental side-effects. Different variants of such a system were investigated in this project, eventually leading to the creation of functional conditional male-sterility systems in two model organisms – the Yellow fever mosquito, Aedes aegypti and the Mediterranean fruit fly, Ceratitis capitata. Both systems utilise chimeric nuclease composed of protamine and FokI cleavage domain fusion. The sperm-specificity and the conditionality of the sterile phenotype have been achieved through the use of tetracycline repressible expression system driven by the β2-tubulin promoter in Ceratitis capitata and by the Topi promoter in Aedes aegypti.

Abstract:
Desde a década de 50, os cientistas tem utilizado radiação ionizante para esterilizar insetos, que são liberados na natureza para acasalar, mas sem nenhuma descendência. Conhecida como a técnica do inseto estéril (TIE), este método de controle de inseto vem tradicionalmente utilizando radiações ionizantes para esterilizar os insetos, sendo uma técnica que não gera resíduo, e pode agir em sinergia com as demais técnicas dentro do manejo integrado de pragas. O Brasil por vários anos vem lutando contra o aumento de pragas, introduzindo novas táticas e técnicas dentro dos programas de MIP, para driblar a resistência dos produtos químicos, como: diminuir os resíduos dos agrotóxicos; para algumas culturas importantes do o nosso país, temos um largo espectro de pragas ocorrendo do inicio ao fim da colheita, uma delas é a cultura do algodoeiro e dentre as pragas chave dessa cultura, temos algumas lagartas extremamente importantes, entre elas Heliothis virescens e Helicoverpa armigera. Essas espécies são parecidas morfologicamente, sendo a segunda identificada a poucos anos aqui no Brasil. Ainda não há trabalhos no Brasil utilizando TIE como ferramenta adicional para lepidópteros, portanto objetivou-se com esse estudo avaliar o efeito de doses de radiação gama nas diferentes fases do ciclo evolutivo de Heliothis virescens e Helicoverpa armigera, bem como avaliar a esterilidade na geração P e a capacidade de competição dos insetos irradiados com os não irradiados. A fase pupa foi a que apresentou um melhor resultado, pois com 75 Gy atingiu a esterilidade em Heliothis virecens e 100 Gy esterilizou Helicoverpa armigera, portanto contemplou a fase e a dose escolhida para avaliar a competição entre os insetos irradiados e os insetos normais de ambas as espécies. E tanto Heliothis virecens como Helicoverpa armigera apresentaram um resultado satisfatório, pois os insetos irradiados conseguiram reduzir significativamente a viabilidade dos ovos na proporção de 9: 1: 1
Since the 1950s, scientists have used ionizing radiation to sterilize insects, which are released in nature to mate, but without any progeny. Known as the sterile insect technique (TIE), this method of insect control has traditionally used ionizing radiation to sterilize insects, a technique that does not generate residues, and can act in synergy with the other techniques within integrated pest management. For several years, Brazil has been fighting against the increase of pests, introducing new tactics and techniques within the IPM programs, to overcome the resistance of chemical products, such as: reducing the residues of agrochemicals; For some important crops of our country, we have a wide spectrum of pests occurring from the beginning to the end of the harvest, one of them is the cotton crop and among the key pests of this crop, we have some extremely important caterpillars, among them Heliothis virescens and Helicoverpa armigera These species are morphologically similar, the second being identified a few years ago in Brazil. There are still no studies in Brazil using TIE as an additional tool for Lepidoptera, therefore the purpose of this study was to evaluate the effect of doses of gamma radiation in the different phases of the evolutionary cycle of Heliothis virescens and Helicoverpa armigera, as well as to evaluate the sterility in generation P And the ability of insects to irradiate with non-irradiated insects. The pupal phase presented the best result because 75 Gy achieved sterility in Heliothis virecens and 100 Gy sterilized Helicoverpa armigera, therefore it contemplated the phase and dose chosen to evaluate the competition between the irradiated insects and the normal insects of both species. Both Heliothis virecens and Helicoverpa armigera presented a satisfactory result, as the irradiated insects managed to significantly reduce the viability of the eggs in a ratio of 9: 1: 1

Abstract:
Ceratitis capitata est une espèce nuisible dont l'histoire est jalonnée d'invasions. La principale technique utilisée, pour contrôler cette espèce est celle du SIT (Sterile Insect Technique). Cette technique qui a un faible impact sur l'environnement, consiste à relâcher périodiquement de grandes quantités d'individus, généralement des mâles qui vont entrer en compétition avec les mâles de la nature pour s'accoupler aux femelles. L'amélioration de cette technique nécessite, d'une part une meilleure connaissance de la dynamique des populations et de la bioclimatologie pour programmer les lâchers et d'autre part, des données sur le comportement sexuel des mâles stériles. Enfin, une analyse du génome de cette espèce pour un élément transposable a été entreprise afin de déterminer si cet élément pourrait être utilisé pour vecteur de transgenèse. Plus précisément, mon travail a porté sur les questions suivantes: 1) L'origine des populations Californienne ; 2) Est-ce que les femelles peuvent s'accoupler plusieurs fois? Si oui, est-ce que la fréquence des ré-accouplements varie avec les conditions écologiques et la taille des populations? 3) Cette espèce est la première à être modifiée par éléments transposables. Actuellement, les meilleurs résultats sont obtenus avec l'élément PiggyBac. Dans la mesure où la présence d'élément de ce type dans le génome hôte peut influencer la stabilité du transgène, j'ai recherché la présence d'éléments de type PiggyBac chez cette espèce ainsi que chez 13 autres espèces de Tephritidae
The medfly, Ceratitis capitata, is a pest species with a long history of invasion success. The major environmentally benign method of pest control is the Sterile Insect Technique. SIT relies on the periodic release into the field of mass-reared sterile flies, preferentially males that should compete with wild males in mating with females. SIT improvement requires knowledge of population dynamics and bioclimatology to program fly releases and knowledge of sexual behavior to have competitive sterile male. My PhD research activity was mainly focused on medfly and covered three fields: population dynamics, sexual behavior and transposable elements. Specifically: 1. Medfly population dynamics: what is the status of medfly in California? 2. Sexual behavior: do medfly females remate in the wild? Does the frequency of remating vary with the varying of ecological condi1ions and population sizes? 3. On genome. Medfly was the first non-drosophilid insect to be genetically modified by transposable elements. Nowadays, the most promising transformation system is based on the element piggyBac. As the presence, in the host species, of endogenous piggyBac-like elements could influence transgene stability, I analysed the presence of piggyBac-like elements in medfly genome. The analysis was extended to other 13 tephritid species. The answers to some of these questions have already been submitted to the attention of the international scientific community, consequently the corresponding papers are included in this thesis after a general introduction of the discussed subject

Abstract:
False codling moth (FCM), Thaumatotibia leucotreta (Meyrick) (Lepidoptera: Tortricidae) is considered the most important indigenous pest of citrus in southern Africa. Major concerns such as progressive insecticidal resistance, the negative impact of insecticides on the environment, as well as the influence of consumers opposed to chemical residues on fruit, created opportunities for biological control methods such as Sterile Insect Technology (SIT). This technology is now established in the Western and Eastern Cape provinces of South Africa as an effective, sustainable alternative to conventional FCM control methods. Due to the prevalence of the pest in all citrus producing areas of South Africa, potential for SIT to expand is enormous. Success of an SIT programme is highly dependent on efficient application of the technology to achieve its objectives in a timeous manner. The aim of this study was to advance the application of SIT for control of FCM on citrus in South Africa, by investigating the effect of certain critical stages in the process. The effect of long-distance transportation on fitness of irradiated FCM was determined, showing reduced performance with cold-immobilized transport. A significant decrease in flight ability and longevity of irradiated FCM was found, although critically, realized fecundity was not affected. The effect of two different insecticides in the pyrethroid and organophosphate chemical groups were investigated for their residual effect on mortality of released irradiated FCM, to determine if these pest control programmes could be integrated. Both chlorpyrifos and tau-fluvalinate were effective in killing irradiated FCM for a number of days after application, after which degradation of the active ingredient rendered it harmless. This effect was found to be similar for irradiated and non-irradiated males, consequently ratios of sterile : wild male FCM should be retained regardless of whether sprays are applied or not. The modes for release of sterile FCM in an SIT programme were investigated. Efficacy of ground and aerial release platforms were tested by evaluating the recovery of released irradiated male FCM in these orchards. More irradiated FCM were recovered in orchards released from the ground compared to air. However, an economic analysis of both methods shows application of irradiated insects over a large geographical area is more cost-effective by air. Depending on the terrain and size of the target area, a combination of both methods is ideal for application of SIT for control of FCM in citrus. Development of application technology for advance of the programme is discussed and recommendations for future research and development are offered.

Abstract:
The Mediterranean fruit fly, Ceratitis capitata (Diptera: Tephritidae), is a ubiquitous pest of fruit trees, causing significant economic damage both in the U.S. and in Israel. Control efforts in the future will rely heavily on the sterile insect technique (SIT). Success of such operations hinges on the competitive ability of released males. The mating system of the medfly is based on leks. These are aggregations of sexually signaling males that attract females (who then select and copulate a courting male). A major component of male competitiveness is their ability to join existing leks or establish leks that are attractive to wild females. Accordingly, we identified leks and the behaviors associated with them as critical for the success of SIT operations. The objectives of this proposal were to determine 1. what makes a good lek site, 2. what are the energetic costs of lekking, 3. how females choose leks, and finally 4. whether the copulatory success of sterile males may be manipulated by particular pre-release diets and judicious spatial dispersal. We established that males choose lek sites according to their spatial location and penological status, that they avoid predators, and within the lek tree choose the perch that affords a compromise between optimal signalling, micro-climatic conditions and predation risk (Kaspi & Yuval 1999 a&b; Field et al 2000; Kaspi & Yuval submitted). We were able to show that leks are exclusive, and that only males with adequate protein and carbohydrate reserves can participate (Yuval et al 1998; Kaspi et al 2000; Shelly et al 2000). We determined that females prefer leks formed by protein fed, sexually experienced males (Shelly 2000). Finally, we demonstrated that adding protein to the diet of sterile males significantly enhances their probability of participating in leks and copulating wild females (Kaspi & Yuval 2000).
