Research Project: Management of insect pests of potato and tree fruits

Location: Fruit and Vegetable Insect Research

2009 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.


3.Progress Report

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 and 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.

A second student developed volatile collection methods for characterizing the phenology of apple odorants and a preliminary assessment was made using store bought apples. GC-EAD methods were used to determine codling moth antennal responses to those odorants. Following a serial dilution of the chemical samples, an assessment was made of which compounds the antenna are most sensitive to. A comparison of EAD responses was made of wild codling moth and colony codling moth, indicating no differences. Close range behavior of codling moth in response to pheromone in an attract-and-kill station design was evaluated to determine the effects of station shape and color, as well as a grease and pesticide formulation. These studies precede a field test for the following season.

ADODR statement: On-site supervision and email were the means of managing on-site research, and email was the principal means of keeping in touch with off-site collaborators.
