Progress Report 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. 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 5320-22430-021-00D (2/10). This is a bridge project progress report for project 5320-22430-023-00D which has replaced project 5320-22430-021-00D which expired on March 31, 2010. A new project 5320-22430-025-00D (Biology, Control, and Area-Wide Management of Fruit Flies and other Quarantine Pests) has been approved. Continuing progress is being made on studies of the biology and ecology of invasive pests of economic importance such as fruit flies, Chinese rose beetle, asian citrus 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 is being evaluated in the Mediterranean fruit fly light brown apple moth system and shown to suppress light brown apple moth (LBAM) for up to 7 days based on trap capture. The pheromone of the Mediterranean fruit fly was reanalyzed. The genome of the oriental fruit fly has been sequenced and assembly and annotation has started. An improved sprayable formulation Specialized Phermone Lure Application Technology-Male Annilation Technique (SPLAT-MAT) has recently been registered for use against fruit flies and is being tested in an Interrregional Research #4 (IR-4) demonstration test. Accomplishments 01 Use of nighttime illumination to protect plants from defoliation by Chinese rose beetle. Environmentally-friendly control methods are neede to protect crops from defoliation by Chinese rose beetle, Adoretus sinic a night-feeding beetle found in Asia, Hawaii and other Pacific Islands, and an invasive risk to the U. S. Mainland. Building on the observation that adult beetles avoid illuminated plants when they select where they will feed at night, an ARS researcher in Hilo, Hawaii, demonstrated that portable, solar-based LED spot light system, providing nighttime illumination over four successive nights, suppressed beetle numbers on a host plant by over 90%. The results clearly show that nighttime illumination has potential for use as a means of reducing the size of Chinese rose beetle populations, and associated aggregate defoliation, o a host plant, such as cacao, a developing specialty crop in Hawaii. Application of these findings may facilitate orchard establishment in th developing Hawaiian cacao industry.

The ADODR monitors progress through regular meetings with cooperators, and through direct supervision of the research project and participation in research activities.
