2007 Annual Report
1a.Objectives (from AD-416)
Develop environmentally acceptable and economically feasible systems for detection, control, suppression, and eradication of the Mediterranean, oriental, melon, and Malaysian fruit flies and other insect pests associated with tropical fruits, vegetables, and ornamentals.
1b.Approach (from AD-416)
Test more environmentally acceptable pesticides and compounds for use in control or eradication programs for fruit flies. Investigate 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 lures, attractants, parapheromones, and baits to be used in improved trap detection devices and/or control systems. Investigate fruit fly and parasitoid olfactory, gustatory, and oviposition aensilla and their electrophysiology. Investigate chemical structure and activity relationships of semiochemicals of fruit flies and their biocontrol agents. Formerly 5320-22430-020-00D (3/05).
In spite of being used in California for the last 25 years and for many eradication programs throughout the Pacific, male annihilation with methyl eugenol and cue-lure are still not legally available in Hawaii for control purposes except on an experimental basis. Through research efforts by scientists at the Tropical Plant Pests Research Unit, Pacific Basin Agricultural Research Center, the University of Hawaii, the Hawaii Department of Agriculture and the Hawaii Fruit Fly Area-Wide Pest Management (AWPM) Program, manufacturer's use permits for methyl eugenol and cue-lure were obtained through partnerships with industry. In addition, the first conditional end product registration for Amulet cue-lure fipronil bait stations has been obtained through the U.S. Environmental Protection Agency and three additional end product registrations are pending. The impact of these registrations will be to provide tools for area-wide control of fruit flies when ARS funding for the AWPM program ends in FY08. The AWPM program has been adopted by 2,540 cooperators, on over 607 farms encompassing 6,383 hectares throughout the state of Hawaii. The program has been the recipient of seven national awards for excellence in technology transfer. The accomplishment will directly address NP304, component IV- Problem Area G -Quarantine by improving control technologies for melon fly and oriental fruit fly.
