1a. Objectives (from AD-416)
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.
1b. Approach (from AD-416)
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. Formerly 5320-22430-023-00D (12/10).
3. Progress Report
Continuing progress is being made on studies of the biology and ecology of invasive pests of economic importance suce as fruit flies, Chinese rose beetle, asian citru psyllid and light brown apple moth. Attractant formulations for fruit flies and moths have been tested in the field and found to last for up to 8 weeks. Mobile mating disruption for light brown apple moth (LBAM) is being evaluated using the Mediterranean fruit fly and was shown to suppress LBAM for up to 7 days with trap capture. An improved sprayable formulation Specialized Phermone Lure Application Technology- Male Anniliation Technique (SPLAT-MAT) has recently been registered for use against fruit flies and is being tested in an Interregional Research #4 (IR-4) demonstration test. In addition, novel solid lure and insecticide dispensers have been shown to be as effective as liquid lures and insecticides. An instructional video on the most important natural enemy of fruit flies in the Pacific was produced and published for worldwide distribution. The genome of the oriental fruit fly has been sequenced and assembly and annotation is progressing rapidly.
