Research Project: AREAWIDE PEST MANAGEMENT OF FRUIT FLIES IN HAWAII
2007 Annual Report


1a.Objectives (from AD-416)
To develop and integrate sustainable tephritid fruit fly management methods in areawide demonstration projects; to form long-term partnerships among federal, state, and the private sector. To transfer to growers economical and ecologically sound technologies to manage tephritid fruit flies on fruits and vegetables, and to enhance the export market. The objectives are to be met by the development and implementation of on-farm areawide pest management partnership demonstration sites in the Hawaiian Islands.


1b.Approach (from AD-416)
Through cooperation with stakeholders and with the help of University, state, federal, and private research agencies, we plan to demonstrate and implement the use of one or more of the following technologies to reduce populations of the four (4) species of fruit flies that attack agricultural crops..
1)Mass-trapping/male annihilation,.
2)bait sprays/bait stations,.
3)augmentative parasite releases, and.
4)sterile fly releases. Evaluation of the effectiveness of these technologies and cost-benefit analysis will be conducted to determine program success. Formerly 0500-00044-016-00D (2/05).


4.Accomplishments
Implementation of the Hawaii Fruit Fly Area-Wide Pest Management Program In 1999, USDA-ARS-PBARC initiated the Hawaii AWPM Program to suppress fruit flies below economic thresholds, reduce the use of organophosphate insecticides, and promote the expansion of diversified agriculture. This program, in cooperation with the University of Hawaii, Hawaii Department of Agriculture, industry, and growers, secured special local needs registrations for agricultural chemicals, implemented a fruit fly IPM extension educational program, developed site specific implementation plans and intiated trapping, sanitation and control measures within defined areas on Hawaii, Maui and Oahu Islands. By the end of FY-2007 the AWPM program had been adopted by 2,540 cooperators, on over 607 farms encompassing 6,383 ha throughout the state. An economic analyst estimated the industry benefit of the AWPM Program to be $3.5 million in 2007 and the internal rate of return (IRR) was calculated to be 28%. Using the AWPM program rather than conventional chemical pesticides, growers reduced fruit fly infestation from 30-40% to less than 5%. California and Florida have also shown a keen interest in the program, particularly, California alone would suffer a $1.4 billion annual loss in export sanctions, treatment costs, lost markets and reduced crop yields if the Medfly became established. Development and application of environmentally friendly area-wide fruit fly controls, as done in the Hawaii AWPM program, are of critical importance to keeping the mainland U.S. free of the same fruit flies already established in Hawaii. The accomplishment will directly address NP 304, component IV-Quarantine by improving control technologies for melon fly and oriental fruit fly Problem area G.
