Biology, Control, and Area-Wide Management of Fruit Flies and Other Quarantine Pests
Tropical Crop and Commodity Protection Research
Project Number: 2040-22430-025-00
Start Date: Jan 12, 2011
End Date: Oct 14, 2015
The proposed work will provide basic and applied information for the development and transfer of appropriate and environmentally acceptable technologies for control of fruit flies and other invasive species. The major objectives of our projects are: 1) Study population dynamics and pest interactions with their natural enemies, host plants, and other pests in the ecosystem; 2)Identify attractants from host and non-host plants and determine physiological and environmental factors affecting or modulating pest behavior; 3)Improve attractants and trapping systems for surveillance, detection, and control of fruit flies and/or other tropical plant pests of quarantine significance; 4)Assess the efficacy and quality of laboratory-reared insects used in SIT and natural enemies for control of fruit flies and other tropical plant pests of quarantine significance, and determine factors limiting their effectiveness; 5) Develop basic understanding of the oriental fruit fly genome, annotation of functional proteins that regulate development, metabolism, sensory reception and sex determination; and 6)Develop area-wide IPM systems including integration of environmentally friendly replacements for organophosphate chemicals to reduce the economic impact of fruit flies and other tropical plant pests.
Test more environmentally acceptable pesticides and compounds for use in control or eradication program for fruit flies. Investigate genomics, biology, and behavior of fruit flies and their parasitoids. Evaluate augmentative parasite releases, mass trapping, male annihilation, sterile fly releases, novel insecticides and food bait sprays as control, suppression, or eradication technologies. Develop new or improved fruit fly strains, lures, attractants, parapheromones, and baits to be used in improved trap detection devices and/or current control systems. Investigate fruit fly and parasitoid olfactory, gustatory, and oviposition aensilla and their electrophysiology. Use genomics, computational biology and area-wide control for fruit flies and other pests.
