2010 Annual Report
1a.Objectives (from AD-416)
1) Develop new pathogen delivery formulations and molecular methods based on pathogenic viruses for control of mosquitoes.
2) Improve parasitoid-based management systems for control of filth flies.
3) Test and develop new and improved pesticides and "attract and kill" systems as management tools for pest and vector species.
4) Discover, evaluate and develop new personal/animal protection tools.
1b.Approach (from AD-416)
Identify and evaluate novel biologically based and self-sustaining biological control agents for mosquitoes and flies; incorporate these into integrated management strategies and demonstration projects. Isolate, identify and validate the efficacy of repellents under laboratory and field conditions to develop new strategies for personal/animal protection from disease vectors and nuisance species. Discover and develop leading candidate compounds from critical screening to targeted applications, to identify new insecticides and more efficacious toxicants for control of mosquitoes and flies.
Year 1: Discovery of chemicals that hide humans and livestock from mosquitoes; development of a release system for attraction-antagonists for mosquitoes; Quantitative Structure Activity Relationship studies to identify new mosquito repellents; establishment of exclusion criteria for Marine Corps Combat Utility Uniforms (MCCUUs). Year 2: Biological validation for the effectiveness of impregnated U.S. MCCUUs; development of a new house fly attractant; obtained the first complete genome sequence for a mosquito pathogenic virus; developed new visual traps for house flies; evaluation of new toxicants for mosquitoes; discovery of natural inhibition of Culex mosquito attraction; use of air curtains for disinsection of aircraft. Year 3: Development of molecular biopesticides for mosquito control; determination of different mosquito behavioral responses to pesticides; behavioral responses of Aedes, Anopheles and Culex mosquitoes to pyrethroid treated surfaces; evaluations of toxic baits for adult mosquitoes; studies on pathogenic virus-mosquito interactions; determined the role of flies in transmitting Salmonella enterica; studies on the salivary gland hypertrophy virus of house flies; evaluated the efficacy of commercial fly traps under desert conditions; discovery of new attraction-inhibitors for mosquitoes. Year 4: Successful use of computer modeling to design novel repellents; laboratory and field evaluation of attraction-inhibitors against mosquitoes and sand flies in Egypt; development of factory-level, permethrin-treated Fire Resistant Army Combat Uniforms for the U.S. Army; development of a high throughput larval screening for new toxicant discovery; excito-repellency compounds to enhance mortality; barrier treatments on native vegetation in a desert habitat for mosquito control. Year 5: Studies of residual barrier treatments on native vegetation and artificial substrates in desert, tropical, and sub-tropical habitats for control of mosquitoes and sand flies; bite protection evaluation of permethrin-treated military uniforms; studies on pesticide-induced gene expression and identification of crucial proteins; evaluation of excito-repellency compounds for control of mosquitoes; insecticide-treated targets for house fly exclusion; further studies on salivary gland hypertrophy virus of house flies; laboratory comparison of attraction-inhibitors against Phlebotomus papatasi sand flies in Egypt; reduction of host-seeking responses of mosquitoes by sub-lethal pesticide exposure; toxicity of carboxamides for adult mosquitoes; development of international guidelines for insecticides and repellents. Beneficiaries of this research include the Department of Defense; Centers for Disease Control and Prevention; Environmental Protection Agency; Animal, Plant and Health Inspection Service; World Health Organization; mosquito abatement districts (livestock producers, pest control industry and the general public). This project has been replaced by project #6615-32000-045-00D.
