Research Project: Areawide Pest Management of Fruit Flies in Hawaii

Location: Tropical Crop and Commodity Protection Research

2010 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 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. (2/10).

3. Progress Report
This is a bridge project progress report for project 0500-00044-029-0029 which has replaced project 0500-00044-016-00D which expired on February 28, 2010. Demonstrations trials at three different Hawaii farms have continued through the Area-Wide Pest Management program. Two new products (SPLAT-MAT-spinosad-ME and Amulet-ME) were recently licensed for area-wide management of fruit flies in Hawaii. Several large field trials are currently underway testing these products at commercial papaya, pumpkin, tomato and cucumber farms. Furthermore, a series of detection devices (Mallet ME, CL, and MC), also developed through the AWPM program, are being evaluated for chemical degradation in the environment to provide data for development of future use patterns. All three of these products also could conceivably be used for detection and eradication of fruit flies on the U.S. mainland. The ADODR monitors progress through regular meetings with cooperators, and through direct supervision of the research project and participation in research activities.
