2010 Annual Report
1a.Objectives (from AD-416)
To develop and formulate effective management strategies to reduce damages caused by insect pests to the tree fruit and vegetable crops.
1b.Approach (from AD-416)
Conduct laboratory and field experiments to gain understanding of behavior, ecology, physiology, genetics, and diseases of potato and tree fruit insect pests. Monitor and manage pest populations in crops. Documents SCA with WSU.
The project goal is to develop management strategies for insect pests of potato and tree fruits. Insect pests of potato and tree fruits are a serious threat to the potato and fruit industry. Research collaboration has been established between ARS and Washington State University to design and conduct laboratory and field experiments to describe the biology and ecology of insect pests of potatoes and tree fruits. Also, experiments are being designed to develop effective monitoring program and management tools for insect pests of potatoes and tree fruits. Currently, a graduate student is looking at the biology and ecology of the potato psyllid to develop effective management strategies for this insect pest to reduce incidence of zebra chip, a new and damaging potato disease in North and Central America and New Zealand.
Experiments were completed to identify volatile odorants of apple fruit that are most stimulating to codling moth antennae. This included assessments of moth antennal response to orchard fruit during both moth flights, and at 3 apple odor concentrations. This work provided a target set of chemicals for field tests of attractiveness.
Monitoring of activities and progress on this project was accomplished by direct supervision of on-site employees, and use of site visits, e-mail and telephone to communicate with off-site collaborators.
