Progress Report Objectives (from AD-416): The object of this cooperative research project is to develop control technologies (male annihilation) in an area-wide pest management program against fruit flies in Hawaii. The overall purpose of the project is to integrate technology developed by ARS and others in specific cropping areas of Hawaii to demonstrate that fruit fly control can lead to increased crop productivity, more environmentally acceptable control methods and economic benefit to those using the technology. The specific goals of the cooperative agreement are to integrate the SPLAT technology provided by Dow AgroSciences and ISCA Technologies of Riverside, California into the area-wide program which will facilitate a broader acceptance of the IPM technology, foster cooperative partnerships in research and education, and better serve the expanding diversified agricultural base of Hawaii and the Pacific. Furthermore, this research will expedite registration of SPLAT-MAT-ME with USEPA for use in the United States. Approach (from AD-416): The work plan identifies the following major areas of study: 1. Research and development of male annihilation treatments that are environmentally sound and effective. 2. Registration with EPA of promising products. 3. Implementation of selected IPM technologies in Hawaii and California. The goal of this Trust Agreement is to provide conventional fruit fly control methods as male annihilation treatments for conventional fruit fly control which directly contributes to objective 6 of the in-house project, "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". Conventional fruit fly control methods such as male annihilation treatments rely heavily on organophosphate insecticides. Continued registration of many organophosphate insecticides for use in the U.S. is in doubt. SPLATT-MAT-spinosad-ME (aka STATICTMME-spinosad), an �attract and kill� sprayable formulation containing the biopesticide, spinosad, was evaluated by the Agricultural Research Serivce (ARS), foreign scientists and industry cooperators as a suppression treatment against oriental fruit fly, in Hawaii; peach fruit fly in Pakistan; and carambola fuit fly, in Brazil. In Hawaii, field demonstration tests were conducted in commercial papaya orchards. Two different application rates (10 or 50 stations per ha) were evaluated and compared to a control (no treatment). Evaluations in Brazil (100 spots/ha) and Pakistan (100 spots/ha) compared their standard methods, organophosphate male annihilation blocks and protein bait sprays (in Pakistan) or an organophosphate cover spray or protein bait spray (in Brazil), respectively, with one application of SPLAT-MAT-spinosad-ME. Rapid reductions in male fruit flies occurred in all three demonstration trials. Our current studies suggest the recently registered biopesticide, STATICTMME-spinosad sprayable �attract and kill� formulation containing spinosad is more convenient and safer to handle than current liquid insecticide formulations which utilize more toxic and less desirable organophosphate insecticides.
