Abstract:
The first fully sequenced insect genomes were those of the fruitfly and the mosquito, both from the order Diptera. Now, with an increasing number and diversity of insect genomes becoming available, the diversity of insect P450 genes can be better appreciated and tentative ideas about the evolution of the CYP (cytochrome P450) superfamily in insects can be proposed. There are four large clades of insect P450 genes that existed before the divergence of the class Insecta and that are also represented by CYP families in vertebrates: the CYP2 clade, the CYP3 clade, the CYP4 clade and the mitochondrial P450 clade. P450s with known or suspected physiological functions are present in each of these clades and only a dozen genes appear to have orthologues or very close paralogues in each insect genome. P450 enzymes from each of these clades have been linked to insecticide resistance or to the metabolism of natural products and xenobiotics. In particular, insects appear to maintain a repertoire of mitochondrial P450 paralogues devoted to the response to environmental challenges.

Abstract:
Maize is one of the major staple foods in Sub-Saharan Africa and there is serious loss in maize storage due to insect damage. This study compared the bioactivity of Bamboo Leaf Ash (BLA) and Bularafa Diatomaceous Earth (BDE) against Maize Weevil (Sitophilus zeamais Motschulsky) under laboratory conditions. Insecto®, a commercialized DE was also tested as standard check. Adults of the insects were exposed on maize admixed with the BLA at dose rate of 5,000, 10,000 and 20,000ppm; BDE and insecto® at a dose rate of 1,000ppm, at 28.20C and 82.2% relative humidity. Mortality increased with increasing exposure duration and all treatments showed mortality of more than 80% after 14days post-treatment compared to negative control with 0%.The treatments suppressed F1 progeny. Treated grains have weight loss less than 4%, kennel damage less than 14% and grain germination showed no significant change. The decreasing efficacy of the dusts against this insect is Insecto®> BLA > BDE. BLA and BDE have potential for the management of insect pests of stored grain in Nigeria.

Abstract:
This study aims to determine the diversity index and the comparison of insect diversity index in Gunung Leuser Bukit Lawang National Park in the Buffer ecosystem area. The research method uses a quantitative descriptive approach. The population in this study were all animals classified as insects (Insecta). The samples used were insects in the buffer forest area with 3 standpoints (lines). The data analysis technique uses the Shannon–Wiener diversity index. The results showed that the insect with the highest significance index (INP) from the three lines (without stands, rubber stands, and cocoa stands) was Macrotermes gilvus, namely 91.71 (rubber tree stands), 87.54 (cocoa tree stands), and 57. 42 (without stands). The insect diversity index H' using (Shannon-Wiener Index) from the three lines without stands (-2), rubber stands (-1), and brown stands (-1) were “low”. The low diversity index of the buffer forest is because the buffer forest in Bukit Lawang is a homogeneous forest.

Abstract:
Olfaction plays an essential role in various insect behaviors, including habitat selection, access to food, avoidance of predators, inter-species communication, aggregation, and reproduction. The olfactory process involves integrating multiple signals from external conditions and internal physiological states, including living environments, age, physiological conditions, and circadian rhythms. As microorganisms and insects form tight interactions, the behaviors of insects are constantly challenged by versatile microorganisms via olfactory cues. To better understand the microbial influences on insect behaviors via olfactory cues, this paper summarizes three different ways in which microorganisms modulate insect behaviors. Here, we deciphered three interesting aspects of microorganisms-contributed olfaction: (1) How do volatiles emitted by microorganisms affect the behaviors of insects? (2) How do microorganisms reshape the behaviors of insects by inducing changes in the synthesis of host volatiles? (3) How do symbiotic microorganisms act on insects by modulating behaviors?

Abstract:
Insect resources are vast and diverse due to their enormous diversity. The exploitation and utilization of insect resources is broadly classified into four different categories. The first category is the insects of industrial resources. This level includes the utilization of silk worm, honeybee, lac insect, dye insect, and aesthetic insect. The second category is the utilization of insects for edible and therapeutic purposes. Insects are high in protein and many are rich sources of vitamins and minerals. The third category is the use of insects in forensic investigation. By analyzing the stages of succession of insects at first, rough estimation of the postmortem intervals can be done. The fourth category is the insects of ecological importance. Many insect species act as potential predators and parasites of destructive pests of insect order Lepidoptera, Diptera, and Orthoptera. Insects are also used as bioindicator to assess the cumulative effects of environmental stressors such as pollutants. Despites these fascinating benefits, insect resources are often neglected in India due to lack of proper documentation, less expertise, and advance enterprises in these fields. Hence, the paper reviews the different fascinating facets of insect resources in order to explore and utilize it in a sustainable way with reference to Indian region.

Abstract:
AbstractWhile insects are eaten by around two billion people globally, they are a relatively new addition to the UK’s culinary landscape. A domestic production sector has begun to emerge to supply this new appetite for insects. Social scientists have been quick to explore consumer attitudes to “edible insects” but insect farmers have thus far been largely ignored. This paper addresses this gap by drawing on interviews with the UK’s current and recent edible insect farmers to explore their understandings of, and approaches to, insect death, something about which all participants expressed concern. The paper examines: 1) reasons for farmers’ concerns around how they kill their insects, ranging from anxieties around insect pain to perceived consumer attitudes; and 2) farmers’ ideas about what constitutes a “good” death for insects, and how they incorporate this in their practices.

Abstract:
Insects are animals with jointed legs that are often found in many places with various types. This is because insects have a very high level of adaptation, for example those found in the Taman Jangkar in Surabaya. The purpose of this study was to describe the diversity of insects in the Taman Jangkararea and to compare the number of members of each insect order in the Taman Jangkar area. The method used in this research task is observation, which is to go directly to the field to capture insects around Taman Jangkar Surabaya with 4 repetitions in each plot, then collect data for identification. Based on the results of observations, collection, and identification, it can be obtained that there are various insects in the area. This is evidenced by the discovery of various orders of insecta, including: order Lepidoptera, order Odonata, order Hymenoptera, order Diptera, and order Orthoptera. Comparison of the number of species from each order is different. The most dominant number of species is in the order Lepidoptera which is then followed by the order Hymenoptera

Abstract:
Insects nurture a panoply of microbial populations that are often obligatory and exist mutually with their hosts. Symbionts not only impact their host fitness but also shape the trajectory of their phenotype. This co-constructed niche successfully evolved long in the past to mark advanced ecological specialization. The resident microbes regulate insect nutrition by controlling their host plant specialization and immunity. It enhances the host fitness and performance by detoxifying toxins secreted by the predators and abstains them. The profound effect of a microbial population on insect physiology and behaviour is exploited to understand the host–microbial system in diverse taxa. Emergent research of insect-associated microbes has revealed their potential to modulate insect brain functions and, ultimately, control their behaviours, including social interactions. The revelation of the gut microbiota–brain axis has now unravelled insects as a cost-effective potential model to study neurodegenerative disorders and behavioural dysfunctions in humans. This article reviewed our knowledge about the insect–microbial system, an exquisite network of interactions operating between insects and microbes, its mechanistic insight that holds intricate multi-organismal systems in harmony, and its future perspectives. The demystification of molecular networks governing insect–microbial symbiosis will reveal the perplexing behaviours of insects that could be utilized in managing insect pests.

Thesis (M.Sc. (Plant Protection)) --University of Limpopo, 2012
Attractiveness of insect pest for use as sources of food may be improved by providing information on preservation and relevant nutritional value. Nutritional composition in edible insects may depend on drying method and/or vegetation (location). Influence of drying method and location on nutritional composition of the African metallic wood boring beetle (Sternocera orissa), widely consumed in certain rural communities of Limpopo Province, South Africa, was investigated. Randomised complete block design in a 3 x 3 factorial arrangement was used with three drying methods (oven-drying, freeze drying, cooking method) and three locations (Khureng, Magatle, Ga-Masemola), with three replicates. Nutritional composition data were subjected to a two-way analysis of variance (ANOVA) and means were separated using Turkey Honestly Significant Differences (HSD) at 5 % level of significance. Relative to freeze-drying, oven-drying and cooking methods increased protein, carbohydrates, fat, energy, ash and dry matter content with the exception of cooking method, which decreased the moisture content. Compared to other locations, Ga-Masemola significantly increased fat and energy of the test beetle. Relative to the freeze-drying method, oven-drying and cooking increased (P ≤ 0.05) essential and non-essential amino acids. Location did not have significant effect on the essential and non-essential amino acids of S. orissa across all the villages. Similarly, oven-drying and cooking increased K, P, Fe, Zn and Mg. Compared to locations, Ga-Masemola increased (P ≤ 0.05) Fe of the test beetle. Results of the study suggested that oven-drying and cooking methods improved the nutritional composition of S. orissa, which has the potential of enhancing nutrition in marginal rural communities of Limpopo Province. Providing results of this study to rural communities through extension services has the potential of improving the attractiveness of this beetle to marginal communities, and thus, increasing harvesting and therefore, reduce insects population densities.

A distribuição do minador-dos-citros, Phyllocnistis citrella Stainton, foi estudada em pomares comerciais de laranjeira 'Pêra-Rio' (Citrus sinensis), com três e dez anos de idade, durante os anos de 2000 e 2001, nos municípios de Taiúva e Jaboticabal, São Paulo, Brasil. No estudo da distribuição na planta, constatou-se que os ovos e as lagartas de P. citrella encontram-se distribuídos por toda a planta, podendo ser realizadas amostragens tanto nas partes inferior e superior, quanto nos quatro quadrantes da planta. Esse inseto preferiu ovipositar na face inferior das folhas mais novas, localizadas no ápice dos brotos, medindo até três centímetros. Constatou-se que a concentração de lagartas no broto aumenta no sentido da extremidade para a base, como também das folhas menores para as maiores. Entre plantas constatou-se que na maioria das amostragens, os índices estudados (Razão variânciaImédia, índice de Morisita, Índice de Green, kcomun da distribuição binomial negativa, b de Taylor e ß da regressão de aglomeração média de Iwao) indicaram que a P. citrella apresenta distribuição agregada. Entre as três distribuições estudadas: binomial negativa, binomial positiva e Poisson, a distribuição binomial negativa foi o modelo que melhor ajustou-se à distribuição da lagarta do minador dos citros em pomares de laranjeira 'Pêra-rio'. Foram desenvolvidos planos de amostragem seqüencial e construídas tabelas para levantamento em campo.
The distribution of the citrus leafminer, Phyllocnistis citrella (Stainton), was studied at 'Pêra-Rio'orange (Citrus sinensis) commercial orchards, with three and ten years old, during the years of 2000 and 2001, at Taiúva and Jaboticabal county, São Paulo State, Brazil. In the study of distribution in the plant, as the eggs and larvae of P. citrella are distributed by the whole plant, samplings in the plant could be accomplished both in the inferior or superior part as in the four quadrants. This insect has preference for oviposition on the inferior face of newest leaves, located at the apex of sprout, measuring up to three centimeters. It was verified that the concentration of larvae in the sprout increases from the apex to the basis, as well as from the smallest to the largest leaves. Among plants, it was verified that in most of the samplings, the studied indexes (Reason variance/mean ratio, Morisita's index, Green's dispersion coefficient, kcommon of the negative binomial distribution, b of Taylor's power law and ß of the Iwao's patchiness regression) indicated aggregated spatial arrangement. Among the three studied indexes, binomial, negative binomial and Poisson, the negative binomial distribution, was the best model to fit the spatial distribution of the citrus leafminer in 'Pêra-Rio' orange orchards. Sequential sampling plans were developed and tables for field monitoring were built.

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.

AbstractStudies to-date have shown the availability of enough genetic diversity in the wheat genetic resources (land races, wild relatives, cultivars, etc.) for resistance to the most economically important insect pests such as Hessian fly, Russian wheat aphid, greenbug, and Sun pest. Many R genes – including 37 genes for Hessian fly, 11 genes for Russian wheat aphid and 15 genes for greenbug – have been identified from these genetic resources. Some of these genes have been deployed singly or in combination with other genes in the breeding programs to develop high yielding varieties with resistance to insects. Deployment of resistant varieties with other integrated management measures plays key role for the control of wheat insect pests.

Abstract:
In recent years, a remarkable number of studies have investigated sensory characteristics, such as flavor and texture, of edible insect and insect-based foods, their contribution to consumers’ attitudes toward edible insects are important in consumer appeal and their willingness to try eating insects in the future. This paper addresses the problem of describing the sensory characteristics aof edible insect and insect-based foods in terms of preferences. To this end, we conducted a study to explore the representations of sensory experiences related to an insect-based dish involving a voluntary sample of 154 consumers. The quasi-experiment, which we have called projective sensory experience (PSE), follows a two-step procedure. In the first step, we asked the participants to imagine tasting an insect-based dish and then to rate, from 1 (imperceptible) up to 10 (very perceptible), the following taste-olfactory sensations: Sapidity, Bitter tendency, Acidity, Sweet, Spiciness, Aroma, Greasiness-Unctuosity, Succulence, Sweet, Fatness, Persistence. In the second step, we asked our interviewees to indicate, through a specific check-list, which was the most disturbing and least disturbing taste-olfactory sensation imagined. We collected data from May to July 2020 by using an anonymous on-line questionnaire. Results could help understand the sensory characteristics of “insects as food” that should be used or avoided, for example, in communication aimed at promoting familiarity with edible insects and improving the acceptability of insects as a novel food.

Abstract:
AbstractThe study of the spatial dynamics of forest insects has a long history, and many forest insect species have served as model systems for studying conceptual processes of population biology and ecology. Because forest insect population data were often collected from georeferenced locations, even prior to the development of geodatabases and spatial statistical software, they provide an important historical resource for understanding insect population dynamics and changes in those dynamics through time. Advances in spatial statistics have furthermore enabled forest entomologists to consider forest insect dynamics over multiple spatial and temporal scales, and vast spatial and temporal extents. In this chapter, we first introduce the importance of scaling in studies of spatial dynamics, and review spatial pattern formation in forest insect populations. We conclude the chapter by addressing metapopulation dynamics, and the concept of spatial synchrony in outbreaking forest insects.

Abstract:
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.

Abstract:
Over the last decades, a decline in insect populations has been observed. Public lighting infrastructure is both expanding to previously unlit areas, and already existing infrastructure is being replaced LED lighting. Consequently, there is a growing imperative to investigate the impact of artificial light at night (ALAN) on nocturnal insect communities. As the correlated colour temperature (CCT) of LEDs is a customisable industry standard, this paper studies its impact on the abundance of attracted nocturnal insects. Data were collected using three LED light sources switching subsequently between 2700K and 6500K, with a similar luminous flux of 6696 lm and 7440 lm, respectively. A vertically positioned white surface gathers attracted insects and facilitates the image-based assessments. Observations during a pilot experiment of four nights in the Belgian Famenne-Ardenne region currently show that the number of attracted insects was 13% higher at 2700K than at 6500K. Broader tests across a wide range of ecosystems and light characteristics will be performed to confirm to which extent these results may be generalized and can inform the development of insect-friendly lighting.

Abstract:
The study of insect and bird flight has always been a curiosity, but it is yet to be described as plentifully as fixed wing aerodynamics. The United States military has expressed an interest in this topic, providing some institutions with funding. The main intention for this type of research is to develop small robots resembling insects or birds for use in exploration, surveillance and intelligence. While conceptually these applications could be accomplished with fixed-wing aircraft, there is a tremendous lack of stealth in these vehicles. The velocities associated with the required lift forces for small flapping-wing insect flights are significantly smaller than for insect-size fixed-wing aircraft. Therefore, it is more feasible and practical to aim for flapping wing flight.

Abstract:
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.

Full text
Abstract:
Insect and pollinator populations are vitally important to the health of ecosystems, food production, and economic stability, but are declining worldwide. New, cheap, and simple monitoring methods are necessary to inform management actions and should be available to researchers around the world. Here, we evaluate the efficacy of a commercially available, close-focus automated camera trap to monitor insect–plant interactions and insect behavior. We compared two video settings—scheduled and motion-activated—to a traditional human observation method. Our results show that camera traps with scheduled video settings detected more insects overall than humans, but relative performance varied by insect order. Scheduled cameras significantly outperformed motion-activated cameras, detecting more insects of all orders and size classes. We conclude that scheduled camera traps are an effective and relatively inexpensive tool for monitoring interactions between plants and insects of all size classes, and their ease of accessibility and set-up allows for the potential of widespread use. The digital format of video also offers the benefits of recording, sharing, and verifying observations.

Learning from Nature How to Design Anti-insect Selective Pesticides - Clarification of the Interacting Face between Insecticidal Toxins and their Na-channel Receptors. United States Department of Agriculture, January 2010. http://dx.doi.org/10.32747/2010.7697101.bard.

Full text
Abstract:
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.

Full text
Abstract:
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.

Abstract:
The gut microbiota affects silkworm growth and development and is particularly associated with food absorption, nutrient use, and disease immunity. The behaviour and evolution of insects are inuenced by interactions with their microbiome. In cases of nutritional deciency or other health conditions, certain microbes can be given as dietary supplements to promote insect reproduction, food conversion, and growth as well as health parasitic infection. An overview of insect-microbiota interactions is provided, as well as information on the function of probiotics, their typical application in the rearing of insects for food and feed, and their interactions with the host microbiota. The improvement of the silkworm's growth and development is greatly aided by nutrition

Full text
Abstract:
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.

Abstract:
The present project is aimed to improve the insecticidal potency of baculoviruses, to American and Israeli lepidopterous pests of Spodoptera and Heliothis species, by engineering recombinant baculoviruses expressing anti-insect toxins derived from scorpion venom. Through this study were isolated recombinant Autographa california M Nucleopolyhedroviruses (AcNPVs) which expressed alpha (LqhaIT), excitatory (AaIT, LqhIT1 and LqhIT3) and depressant (LqhIT2) anti-insect neurotoxins. Bioassays on Heliothis species (Helicoverpa armigera and Heliothis virescens) were employed to assess the potency of the viruses. The recombinant viruses possessed an enhanced speed of kill compared to wild type AcNPV. Recombinant AcNPVs expressing the depressant toxins emerged as appealing improved baculoviruses. Applied combinations of alpha, excitatory and depressant toxins enhanced their insecticidal activity against blowfly and lepidopterous larvae. Moreover, combined application of recombinant AcNPVs expressing LqhaIT and AaIT possessed increased insecticidal activity compared to single applications of them. A reduced growth rate of H. virescens larvae was obtained by comparing the larvae infected with recombinant AcNPV expressing AaIT under the control of the AcNPV early ie1 to the very late p10 promoters. Through this project improved protocols and methods were developed to purify and bioassay the anti-insect toxins and their correspondent recombinant baculoviruses. A novel highly potent anti-insect toxin Aa IT5 was isolated and characterized. Finally, the impact of use of recombinant baculoviruses, expressing anti-insect scorpion neurotoxins to non-target insects, was evaluated.

Abstract:
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.
