2013 Annual Report
2. Test novel quarantine treatments for phytosanitary applications on imported and exported fruit or other commodities.
3. Develop practical systems for integrated pest management that reduce the threat of importation of exotic pests from foreign tropical and subtropical environments.
Laboratory and field tests of sugar baits for caribflies. Laboratory wind tunnel tests and field tests are ongoing to test the effect of age on fermenting sugar baits on attraction of caribflies. This study follows research conducted previously that determined EAG response of female caribflies to these baits. This information will be used to identify new attractants for caribflies.
Field tests of synthetic lures for pest drosophilid fruit flies. Field tests are ongoing to test synthetic lures for pest the drosophilid African fig fly. Field tests were conducted to test combinations ten chemicals identified from wine and vinegar that have been found to be successful for other pest drosophilids. Results of this research may lead to development of a synthetic lure for detecting new infestations of this pest or monitoring established populations.
EAG analysis of medfly response to synthetic chemicals identified from essential oils. Laboratory studies are ongoing to quantify EAG response of sterile male medflies to five chemicals identified from plant essential oils. These oils have been found to be attractive to sterile and wild medflies in laboratory and field trials conducted previously.
Field and laboratory evaluations of cubeb bubble lure for redbay ambrosia beetle (RAB). Comparative research with plant essential oils identified cubeb oil as a new attractant for RAB (see accomplishment below). Tests are ongoing to evaluate a commercially available formulation of cubeb oil (bubble lure). These tests will include (1) field trials to determine efficacy and longevity of cubeb bubble lures relative to manuka and phoebe oil lures, (2) volatile collections followed by gas chromatography-mass spectroscopy to quantify lure emissions over time, and (3) electrophysiology studies to assess RAB olfactory responses.
