DEVELOPMENT OF IMPROVED TRAPPING SYSTEMS FOR INVASIVE FRUIT FLIES THAT THREATEN U.S. AGRICULTURE
Subtropical Horticulture Research
2010 Annual Report
1a.Objectives (from AD-416)
The objective of this cooperative research project is to develop improved fruit fly trapping and control systems and integrated pest management programs for control of exotic fruit flies that threaten U.S. agriculture. Populations of fruit flies that are not found in the continental US, but that are of quarantine concern for US agriculture, are endemic in Honduras. These include Mediterranean fruit flies, Mexican fruit flies, West Indian fruit flies and guava fruit flies. The research objective is to determine effective sampling area of traps and lures developed by the scientists at SHRS and to assess antennal sensitivity to food-based lures.
1b.Approach (from AD-416)
The cooperator at the Honduran Foundation for Agricultural Research (FHIA) has been involved in collaborative research with ARS in an IAEA-funded research project. This research will be expanded to include research on determining the effective sampling area for traps baited with the food-based synthetic attractant developed by ARS, critical information that is needed by State and Federal action agencies in the US for use in detection and delimitation of fruit flies. The cooperator will locate properties and appropriate sites for the studies, obtain wild flies from infested host material, will conduct mark and recapture studies to address this research following a protocol that will be developed jointly by ARS and FHIA. ARS will provide equipment, training and protocols to FHIA personnel for the antennal sensitivity studies.
This research relates to inhouse objective: The long-term objective of this project is to develop trapping and control components and systems for integrated pest management of exotic pest insects in the Caribbean, Central and South America that pose a threat to U.S. agriculture.
Field studies were conducted to determine attraction of medflies to several male-targeted substances. Parallel laboratory studies were conducted in Florida using sterile medflies. Results of these studies will be used to identify additional chemicals that may be used for medfly detection and control.
Monitoring activities: Methods of monitoring research activities conducted under this agreement include phone discussions and email communications.
