Abstract A field study was conducted on Victoria sandy clay loam at the Texas A&M Agricultural Research and Extension Center at Corpus Christi, Texas to determine the efficacy of Orthene 75S as a hopperbox seed treatment for control of early season cotton pests. Test plots were planted 24 Mar, with ‘Tamcot SP-21S’, a cotton fleahopper susceptible variety. The soil type was Victoria sandy clay loam. Treatments were replicated 4 times in plots 80 ft long by 12 rows wide (0.07 acre) in a randomized complete block design. The planting rate was approximately 20 lb seed/acre. Cotton seed and Orthene 75S for each treatment were mixed dry by shaking them together in a large plastic bag prior to filling the hopperboxes.

Earth mites are a complex of related species introduced into Australia in the early part of last century that cause economic damage to crops, especially canola, and to pastures. A general method of chemical control aimed at interrupting the life cycle at the most effective stage, by spraying in the spring before the mites enter diapause, has recently been adopted for controlling earth mites, particularly the redlegged earth mite Halotydeus destructor (Tucker). Here we use paired-paddock treatments and field enclosures to test the effectiveness of this method on pest populations of H. destructor as well as on other pests over two seasons at multiple pasture sites in Victoria. Halotydeus destructor numbers at the start of the winter growing season were suppressed by up to 85%, but this control level was not sustained. The numbers of H. destructor and other pests were similar to or higher than those in the unsprayed areas by spring. Spring spraying is, therefore, a useful means of suppressing H. destructor in early autumn, but its effects disappear relatively quickly over time in Victoria. This strategy also has little impact on the control of the blue oat mite Penthaleus major (Duges) and other phytophagous invertebrate pests.

This paper discusses the development and implementation of integrated pest management (IPM) strategies for broadacre cropping in Victoria, Australia, with reference to other crops and also the levels of adoption of IPM in Australia and overseas. Levels and rates of adoption are mostly low but with some exceptions. The reasons for differing levels of adoption include the failure of strategies to successfully deal with all pests, the lack of motivation to change to using IPM given current successful pesticide-based controls, and the poor availability of IPM advisors in the field. This paper outlines how IPM strategies for wheat, barley and canola crops were developed and implemented using a collaborative approach between farmers, agronomists and entomologists. It was found that although there were no existing specific IPM strategies for the crops grown in the region of south-eastern Australia, there was sufficient information for farmers to start using an IPM approach. This paper gives a case study of implementing change to IPM from conventional pesticide spraying, including the development of a course in IPM for growers and agronomists. It focuses on the process of changing practices and information transfer rather than on entomological details.

Biological pest control techniques usually have identifiable costs and constraints that they must overcome before they will be adopted by farmers. Many biological control agents are developed in the public sector and need economic assessments at an early stage. The methods often have hidden costs related to farm labor adjustments or initial costs of development. Living biological controls frequently escape, and they may be disrupted by pesticides, regulations, or farm commodity programs. Pest control registration procedures and small markets also present obstacles. Area-wide implementation programs and changes in incentives for researchers may speed development and adoption of biological controls.

In this paper, we propose two impulsive differential systems concerning biological and, respectively, integrated pest management strategies. In each case, it is observed that there exists a globally asymptotically stable susceptible pest-eradication periodic solution on condition that the amount of infective pests released periodically is larger than a certain critical value. When the amount of infective pests released is less than this critical value, the system is shown to be permanent, which implies that the trivial susceptible pest-eradication solution loses its stability. Further, the existence of a non-trivial periodic solution is also studied by means of numerical simulations. In the case in which a single control is used, one can only use the amount of infective pests which are periodically released in order to control pests at desirable low levels, while in the case in which integrated management is used, one can use the proportion of pests removed by means of spraying chemical pesticides together with the amount of infective pests which are periodically released to control pests at desirable low levels.

Abstract Cotton was planted 15 Apr at the Texas Agricultural Experiment Station annex farm in Mercedes. Experimental design was a randomized complete block with 5 replicates. Plots were 2 beds wide and 40 ft long with 2 beds of sorghum between plots and 20-ft alleys between plots in rows. Applications were made with a tractor-mounted CO2-powered sprayer that delivered 20 gal/acre. Three nozzles were used for each bed, 1 over the top of plants and 1 on a drop on each side of the plants. All plots were treated with cypermethrin (0.01 lb [AI]/acre) at 7-d intervals to induce secondary pest population increases. Surveys were conducted at 7-d intervals by collecting the third fully expanded leaf down from the terminal of each of 3 plants/plot. Leaves were returned to the laboratory and mites and aphids were counted. Plots were treated with Capture 2 EC on 22 and 28 Jul.

Insect pests of agricultural significance pose substantial risks for food security in an ever-growing global population. Conventional control measures used against these pests have had varying degrees of success and examples of pesticide resistance and offtarget effects of pesticides highlight the urgent need for the development of new, environmentally benign control methods. Deployment of ‘self-limiting’ insects is a species-specific approach that can be used to combat many species, including two major agricultural insect pests, the Medfly, Ceratitis capitata, and the Diamondback moth (DBM), Plutella xylostella. In this thesis, I used transgenic ‘self-limiting’ strains of medfly and DBM to stress-test self-limiting technology in laboratory and field scenarios. In Chapter 2, I tested the effect of larval diet composition on the penetrance of a female-specific self-limiting system in the OX3864A strain of medfly under simulated control conditions. In Chapter 3 I investigated the potential for resistance to selflimiting systems, using artificial selection for survival under a low dose of the transgene antidote, in the OX3864A medfly strain. In Chapter 4 I used the OX4319L self-limiting strain of DBM and showed that its responses to an artificial pheromone source in wind tunnel flight trials were comparable to the wild type. I also described the field dispersal characteristics of a long-term, laboratory-reared wildtype DBM strain in a mark-release-recapture trial. In Chapter 5 I demonstrated that the OX4319L DBM strain had comparable field longevity, but reduced mating competitiveness, in comparison to a wild-caught DBM strain. Finally, in Chapter 6, I discuss the broader context and address the practicalities, regulatory controls and implications of transgenic technologies for insect pest control under open field conditions.

The interaction between an increasing global human population and a number of important long-term trends and issues are putting strain on food production. Insects represent a significant food security concern causing up to 15% of global crop losses. Conventional chemical methods are ineffective; inducing resistance and degrading the environment. Sustainable alternatives are sought. The sterile insect technique provides a sustainable solution. Genetic engineering can augment this historic technique by replacing radiation-induced sterilization with sperm-specific nuclease expression to introduce double-stranded DNA breaks in the gametes of mass-reared and released males. This paternal-effect system is dependent on elucidation of appropriate sperm-specific promoters and suitable chaperone-nuclease combinations. This thesis develops this technology in the SIT neglected insect orders, the Lepidoptera and Coleoptera. Specifically the Plutella xylostella (Plutella xylostella, L.) and the red flour beetle (Tribolium castaneum, Herbst). I provide the foundations for a paternal-effect genetic-control-system in both species by developing a conditional sperm-specific expression system in Plutella xylostella and a female-specific expression system in Tribolium. Mass-rearing insects for the genetic control of a species can be augmented by recent developments in RNAi. I show that the sex ratio of Tribolium can be adjusted by treatment with dsRNA transformer, producing pseudomales as an additional bonus. In addition, an exploratory data analysis of producing transgenic lines in insects using piggyBac was undertaken. As well as providing a comprehensive compendium and assessment of the transgenic literature, something not yet published elsewhere, a predictive model was produced that could be very useful to a wide diversity of researchers in insect molecular biology, developmental biology, disease biology and genetics. It is hoped that this work will contribute towards the effective control of the Plutella xylostella in the near term, and form a model for the sustainable control of other lepidopteran and coleopteran species through genetic pest management.

Cryptophlebia leucotreta is an economically important agricultural pest throughout Sub-Saharan Africa. CrleGV has been considered as an alternative to chemical control of this pest due to its host specificity and innocuous nature towards vertebrates. A CrleGV free laboratory colony of C. leucotreta would be useful for the isolation of genotypically pure strains of the CrleGV and for virulence comparisons between isolates. It is preferable to have a full characterisation of CrleGV prior to its registration and release into the environment as a biopesticide. A laboratory colony of C. leucotreta, set up at Rhodes University, containing a low level of infection indicated that CrleGV is vertically transmitted. To establish a virus free laboratory colony of C. leucotreta, a solution of 3.5% sodium hypochlorite and 1% Tween 20 was used to surface decontaminate C. leucotreta eggs for removal of transovum CrleGV from the laboratory colony. No apparent infection by CrleGV was induced by subjecting larvae to stress. PCR of DNA extracted from larvae using CTAB failed to detect virus in the laboratory colony. This detection protocol was able to detect down to 60 fg (480 genome copies of CrleGV). The possibility of low-level virus remaining in the colony requires monitoring of genotypic purity of virus manipulated in the colony. Sequencing of Bam HI/KpnI fragments produced a preliminary sequence of the granulin region of CrleGV. This preliminary sequence supports the trend that the gene organisation of the granulin region of the granuloviruses infecting the family Tortricidae is conserved.

Анотація:
The within-field spatial distribution of F₁, F₂, and F₃ pink bollworm (PBW) (Pectinophora gossypiella Saunders) generations were modeled with Taylor's power law (TPL), Iwao's patchiness regression (IPR), and the geostatistical semivariogram. Kriging interpolation was used to grid data for the generation of isarithmic maps. Distributional patterns and movements within a field are displayed in a time series of three maps depicting density across the field. The sampling protocol was replicated in eight commercial cotton fields in south-central Arizona during 1985 and 1986. Permanent sample stations were situated throughout the fields on a regular grid pattern. Samples were collected during the peak larval population and handled so as to maintain the integrity of site-specific samples (spatially identified by X,Y coordinates). TPL and IPR could not be used satisfactorily to model the F₁ generation. TPL fit the observed F₂ and F₃ data better than IPR. Both methods predicted the F₂ to be more highly aggregated than the F₃. For a given precision, optimum sample size increased when TPL and IPR model parameters were incorporated into sample size formulae relative to a formula which assumed random distribution. Ninety-five percent of the modeled PBW distributions were autocorrelated in 2-dimensional space and shown to conform to regionalized variable theory by the successful application of geostatistics. The semivariogram models are in conceptual agreement with traditional models and represent a worthy alternative to traditional modeling methodology. The semivariogram models have a large nugget effect proportion (average = 67%) which, in combination with low PBW density in commercial fields, limits the applicability of geostatistics in this system. Isarithmic maps showed that F₁ larvae are either localized near a field edge or generally scattered throughout the field. No consistent inter-generational dispersal pattern was identified. The use of systematic grid sampling is most advantageous (relative to random sampling) when density and the spatial dependence of samples is high, or many samples can be taken. Systematic sampling and kriging estimation yielded more precise estimates than random sampling and classical statistics, but the advantage was buffered by low PBW densities and large nugget effect.

The purpose of this study was to assess the adoption response of cotton growers to Integrated Pest Management (IPM) programs, identify the extension strategies used to promote IPM, and provide descriptive comparison of IPM programs between the foremost eleven cotton-producing states in the United States. Integrated pest management is presented as an alternative agricultural production strategy referred to as sustainable agriculture. IPM programs for cotton were evaluated by use of a survey instrument and telephone interviews with the IPM coordinators for the eleven cotton-producing states. The most significant findings were that programs vary considerably between states; the most widely employed IPM techniques were selective use of chemicals, use of economic thresholds and sampling for pests; the Cooperative Extension Service worked closely with private consultants and grower associations; and adoption of a wide variety of IPM techniques has been extensive for cotton producers in the eleven foremost cotton-producing states.

This thesis reports laboratory and field investigations on the aspects of biology of the Stethorus vagans, an Australian ladybird that feeds on all stages of two-spotted mite, Tetranychus urticae. Aspects of the biology of S. vagans were studied in the laboratory at constant and fluctuating temperatures. They regularly fed on all stages of T. urticae and there was no significant difference in male and female longevity at different temperatures. For field studies potted French bean plants infested with T. urticae were exposed in the field. Adult S. vagans was found to consume a range of alternative prey if the primary host was not available, but only one of the alternative hosts had the potential to support reproduction. Time partitioning behaviour and prey consumption rates were assessed, and how S. vagans located their prey was investigated. S. vagans exhibited many of the attributes of an effective biological control agent such as high reproductive level, location of prey at low levels, reproduction at low densities, and ability to feed on alternative hosts. It is concluded that S. vagans has a number of characteristics likely make them useful as a natural enemy of T. urticae

Abstract The African Union Malabo Declaration outlines goals to achieve sustainable production practices for economic growth in the agriculture sector by 2025. Conservation Agriculture (CA) practices represent a climate smart and resource friendly sustainable production system, and these need to be adopted and refined. This will be a paradigm shift for academics, experts and farmers who are embedded in the intensive external-input monoculture tillage systems. From our review of literature, recent history has shown that CA systems are successful and profitable while using less external inputs and expending less energy. Energy use can be reduced by 40% and labour needs by 50%-90%. Research has shown that CA farming is superior in terms of enhancing soil functions, biodiversity, beneficial insects, energy consumption, greenhouse gas (GHG) emissions and resilience to extreme climate events. Nitrogen and other essential elemental crop needs can be reduced by 10%-70% through CA systems. African research and farm testing have shown integrated CA cropping systems can control insect and weed pests while providing more diverse economic crops. For the paradigm shift to occur quickly, efficiently and economically, institutions need to lead change. Policy makers need to start strategic changes to research and institutions by initiating support programmes identified by innovative researchers and agricultural leaders that can move the Malabo dial towards the 2025 goals.

Abstract In this chapter, the need to take a more critical look at the highly precarious and vulnerable situation of smallholder farming systems, the predominant type of the agricultural output worldwide, is emphasized. These farmers represent 98% of the farmers in the world that sustain the local production of staple crops such as rice, maize, cassava, groundnut and millet. Although there is some disparity in the figures, recent data estimates that there are between 380 and 500 million smallholder farming households globally. The productivity of the smallholders' farms depends on soil health and quality, agroecological conditions (irrigated versus rainfed), access to agricultural inputs and new technologies. These last two also critically influence smallholders' ability to manage pests and diseases, including plant parasitic nematodes (PPN). This chapter discusses the epidemiological perspective, diagnostics and surveillance, alternate host and in-field spread of PPN. Breeding programmes for PPN resistance, seed delivery system, importance of clean planting material, influence of land availability to smallholders' ability to practice fallow and rotation for nematode management are described. The use of trap crops, cover crops, nematicides and biological control agents for nematode suppression are also discussed. Future developments aimed at promoting the progress of smallholder farming systems are also mentioned.

AbstractClimate change is a global issue threatening food security, environmental safety, and human health in tropical and developing countries where people depend mainly on agriculture for their livelihood. Nigeria ranks among the top in the global yam production. It has the largest population in Africa and has been able to secure food for its growing population through food crops especially yam. Unfortunately, the recent increase in termites’ colonies due to climate change threatens yam yield. Besides harming man and environment, pesticides are expensive and not easily accessible to control the pests. This prompted a study which aimed at applying a biotrado-cultural approach in controlling the termites, as well as improving soil chemical properties and yam production. The study hypothesized that Chromolaena odorata and Elaeis guineensis sludge improved soil nutrient and yam yield and consequently decreased termites’ outbreak. In a randomized design experiment of five blocks and five replicates, five different treatments including unmanaged (UM), Vernonia amygdalina (VA), Chromolaena odorata (CO), Elaeis guineensis (EG) liquid sludge, and fipronil (FP) were applied in termites-infested agricultural soil. Data were collected and measured on the responses of soil chemical properties, termites, and yam yield to treatments using one-way ANOVA, regression, and multivariate analyses. The result showed that Chromolaena odorata (CO) and EG treatments were the best treatments for controlling termites and increase yam production. Termites were successfully controlled in VA and FP treatments, but the control was not commensurate with yam production. The experiment needs to be extended to other locations in the study region. It also requires an intensive and long-term investigation in order to thoroughly understand (i) the influence of climate change on the termites’ outbreak, (ii) the extent of termite damage to the crops, (iii) the impacts of climate change and variability on yam yields, (iii) the agricultural and economic benefits of the applied treatments, and (iv) the ecological and human health safety of the treatments.

This chapter covers ASV’s conflicts due to financial problems and the failure of acclimatization species and acclimatized animals that became agricultural pests, such as rabbits. The rabbit population, which became known as the rabbit plague, caused ruined crops and environmental disasters. Farmers demanded the right to destroy rabbits, protection of their property rights, and revision of the game laws. Recognizing the failure, the institution questioned the utility of acclimatized terrestrial vertebrates for pest control and emphasized protecting agriculturally useful native animals to control pests. New generation of scientists in the Field Naturalists Club of Victoria (FNCV) and the Zoological and Acclimatisation Society of Victoria (ZASV) were concerned with national nature, extinction, and animal welfare. Recommended strategies like seasonal protection of animals were issued to prevent the possibility of imminent extinction.

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.

Industrial development artificial mechanical drying came into practice. This process is energy intensive and expensive. It increases product cost. The efforts to enhance sun drying have led to solar drying. Solar dryers control the drying process. Also protect agricultural foods from damage by insect pests dust and rain. The solar drying system utilizes solar power to heat up air and to dry any food substance. This is useful in reducing wastage of agricultural product and helps in preservation of agricultural product. The restrictions of the natural sun drying exposure to direct sunlight, liability to pests and rodents lack of proper monitoring. The intensify cost of the mechanical dryer a solar is developed to cater for this disadvantage. In the dryer, the heated air from a separate solar dish is skilled a grain bed, and at an equivalent time, the drying cabinet absorbs solar power directly through the transparent walls and roof.

We are developing laser based fluorescence particle counters and spectrum analyzers which should be useful for real-time monitoring of airborne bacteria, proteins or other particles. Improved methods for detecting and characterizing airborne particles could be useful in applications such as studying the spread of diseases of plants, animals, and humans, or determining the sources of particles in clean rooms. Many airborne bacteria, pollens and viruses are of medical, agricultural, or ecological interest. Some diseases of humans (e.g., tuberculosis), of farm animals, of agricultural crops, and of forest trees are commonly transmitted through the air. Some airborne pollens cause allergies in humans. Bacteria (e.g., Bacillus thuringensis) used to control certain pests are commonly disseminated through the air.

Insects have a strong relationship with the human-beings. For example, some species of mosquito transmit diseases that kill millions of people around the world. At the same time, the presence of certain insects is essential for the ecological balance and food production. For this reason, we are developing a novel sensor as a tool to efficiently control disease vectors and agricultural pests without harming other species. In this paper, we demonstrate how we overtook the most important challenge to make this sensor practical: the creation of accurate classification systems. Despite the short duration and the very simple structure of the signal, we managed to successfully identify relevant features using speech and audio analysis techniques. We show that we can achieve an accuracy of 98% in the task of disease vector mosquitoes identification.

Objectives: The Israeli work plan regarding HBTM included: (a) producing a better diagnostic method; (b) following infestations during the season and evaluating damage to resistant bees and, (c) controlling HBTM by conventional means under local conditions. For varroa our plans to try novel control (e.g. oil novel control (e.g. oil patties & essential oils) were initially delayed by very low pest populations, then disrupted by the emergence of fluvalinate resistance. We monitored the spread of resistance to understand it better, and analyzed an underlying biochemical resistance mechanism in varroa. The US work plan focused on novel management methods for both mites with an emphasis on reducing use of traditional insecticides due to resistance and contamination issues. Objectives were: (a) evaluating plant essential oils for varroa control; (b) exploring the vulnerability of varroa to desiccation for their management; and (c) looking for biological variation in HBTM that could explain virulence variability between colonies. Although the initial PI at the USDA Beltsville Bee Lab, W.A. Bruce, retired during the project we made significant strides especially on varroa water balance. Subcontracts were performed by Yoder (Illinois College) on varroa water balance and DeGrandi-Hoffman (USDA) who evaluated plant essential oils for their potential to control varroa. We devised an IPM strategy for mite control i the U.S. Background: Mites that parasitize honey bees are a global problem. They are threatening the survival of managed and feral bees, the well-being of commercial/hobby beekeeping, and due to pollination, the future of some agricultural commodities is threatened. Specific economic consequences of these mites are that: (a) apiculture/breeder business are failing; (b) fewer colonies exist; (c) demand and cost for hive leasing are growing; (d) incidences of bee pathogens are increasing; and, (e) there are ore problems with commercial-reared bees. As a reflection of the continued significance f bee mites, a mite book is now in press (Webster & delaplane, 2000); and the 2nd International Conference on Africanized Honey Bees and Bee Mites is scheduled (April, 2000, Arizona). The first such conference was at OSU (1987, GRN was co-organizer). The major challenge is controlling two very different mites within a colony while not adversely impacting the hive. Colony management practices vary, as do the laws dictating acaricide use. Our basic postulates were that: (a) both mites are of economic importance with moderate to high infestations but not at low rates and, (b) once established they will not be eradicated. A novel strategy was devised that deals with the pests concomitantly by maintaining populations at low levels, without unnecessary recourse to synthetic acaricides. Major Conclusions, Solutions, Achievements: A major recent revelation is that there are several species of "Varroa jacobsoni" (Anderson & Trueman 1999). Work on control, resistance, population dynamics, and virulence awaits knowing whether this is a problem. In the U.S. there was no difference between varroa from three locales in terms of water balance parameters (AZ, MN & PA), which bodes well for our work to date. Winter varroa (U.S.) were more prone to desiccation than during other seasons. Varroa sensitivity to desiccation has important implications for improving IPM. Several botanicals showed some promise for varroa control (thymol & origanum). Unfortunately there is varroa resistance to Apistan in Israel but a resistance mechanism was detected for the first time. The Israel team also has a new method for HBTM diagnosis. Annual tracheal mite population trends in Israel were characterized, which will help in targeting treatment. Effects of HBTM on honey yields were shown. HBTM control by Amitraz was demonstrated for at least 6 months. Showing partial resistance by Buckfast bees to HBTM will be an important IPM tactic in Israel and U.S.

The extensive use or non-specific, hazardous, chemical insecticides demands the development of "healthier" alternative means for pest control. Insect-specific, baculoviruses expressing anti-insect toxin genes (from mites or scorpions) demonstrated in laboratory assays and field trials enhanced insecticidal activity and provided some protection from lepidopterous larvae to agricultural plantations. To utilize recombinant baculoviruses as commercial biopesticides in row crop agriculture, further increase in their speed of kill should be achieved and the reduction in crop damage should be comparable to the levels obtained with organic insecticides (the problem). In this project we developed strategies to improve further the efficacy of recombinant baculoviruses which included: I) Synergism among baculoviruses expressing different anti-insect toxins: a) Synergism among two complementary anti-insect scorpion neurotoxins each expressed by a separate recombinant baculovirus, both regulated by the same or a different viral promoter. b) Synergism among two complementary anti-insect scorpion neurotoxins expressed by the same recombinant virus, both regulated by the same or a different viral promoter respectively. The above included two classes of pharmacologically complementary toxins: i) toxins with strictly anti-insect selectivity (excitatory and depressant); ii) toxins with preferential anti-insect activity (anti-insect alpha toxins). c) Synergism among wild type viruses, recombinant baculoviruses and chemicals (insecticides and phytochemicals) II) Identification of more potent toxins against lepidopterous pests for their expression by baculoviruses. Our approach was based on the synergistic effect displayed by the combined application of pairs of anti-insect toxins to blowfly and lepidopterous larvae that resulted in 5 fold increase in their insecticidal activity without apparent increase in their anti-mammal toxicity (toxins LqhIT2 and LqhaIT, LqhIT2 and AaIT, and LqhaIT and AaIT (1). Thus, we developed new concepts and produced a "second generation" of recombinant baculoviruses with enhanced potencies and speeds of kill comparable to classical insecticides. These achievements contribute to make these biopesticides a viable alternative to minimize the use of hazardous chemicals in pest control. Also, our project contributed new tools and model systems to advance the study of insect sodium channels.

Plant species synthesize a multitude of specialized compounds 10 help ward off pests. and these in turn may well serve as an alternative to synthetic pesticides to reduce environmental damage and health risks to humans. The general goal of this research was to perform a genetic and biochemical dissection of the natural-insecticides methylketone pathway that is specific to the glandular trichomes of the wild species of tomato, Solanumhabrochaites f. glabratum (accession PI126449). Previous study conducted by us have demonstrated that these compounds are synthesized de novo as a derivate pathway of the fatty acid biosynthesis, and that a key enzyme. designated MethylketoneSynthase 1 (MKS 1). catalyzes conversion of the intermediate B-ketoacyl- ACPs to the corresponding Cn-1 methylketones. The approach taken in this proposed project was to use an interspecific F2 population. derived from the cross between the cultivated lV182 and the wild species PIl26449. for three objectives: (i) Analyze the association between allelic status of candidate genes from the fatty acid biosynthesis pathway with the methylketone content in the leaves (ii) Perform bulk segregant analysis of genetic markers along the tomato genome for identifying genomic regions that harbor QTLs for 2TD content (iii) Apply differential gene expression analysis using the isolated glands of bulk segregant for identifying new genes that are involved in the pathway. The genetic mapping in the interspecific F2 population included app. 60 genetic markers, including the candidate genes from the FAS pathway and SSR markers spread evenly across the genome. This initial; screening identified 5 loci associated with MK content including the candidate genes MKS1, ACC and MaCoA:ACP trans. Interesting observation in this genetic analysis was the connection between shape and content of the glands, i.e. the globularity of the four cells, typical to the wild species. was associated with increased MK in the segregating population. In the next step of the research transcriptomic analysis of trichomes from high- and 10w-MK plants was conducted. This analysis identified a new gene, Methy1ketone synthase 2 (MKS2), whose protein product share sequence similarity to the thioesterase super family of hot-dog enzymes. Genetic analysis in the segregating population confirmed its association with MK content, as well as its overexpression in E. coli that led to formation of MK in the media. There are several conclusions drawn from this research project: (i) the genetic control of MK accumulation in the trichomes is composed of biochemical components in the FAS pathway and its vicinity (MKS 1 and MKS2). as well as genetic factors that mediate the morphology of these specialized cells. (ii) the biochemical pathway is now realized different from what was hypothesized before with MKS2 working upstream to I\1KS 1 and serves as the interface between primary (fatty acids) and secondary (MK) metabolism. We are currently testing the possible physical interactions between these two proteins in vitro after the genetic analysis showed clear epistatic interactions. (iii) the regulation of the pathway that lead to specialized metabolism in the wild species is largely mediated by transcription and one of the achievements of this project is that we were able to isolate and verify the specificity of the MKS1 promoter to the trichomes which allows manipulation of the pathways in these cells (currently in progress). The scientific implications of this research project is the advancement in our knowledge of hitherto unknown biochemical pathway in plants and new leads for studying a new family in plants (hot dog thioesterase). The agricultural and biotechnological implication are : (i) generation of new genetic markers that could assist in importing this pathway to cultivated tomato hence enhancing its natural resistance to insecticides, (ii) the discovery of MKS2 adds a new gene for genetic engineering of plants for making new fatty acid derived compounds. This could be assisted with the use of the isolated and verified MKS1 promoter. The results of this research were summarized to a manuscript that was published in Plant Physiology (cover paper). to a chapter in a proceeding book. and one patent was submitted in the US.
