Research Project: Development of a pest-specific monitoring tool for potato payllid

Location: Temperate Tree Fruit and Vegetable Research

2013 Annual Report

1a. Objectives (from AD-416):
Develop new monitoring tool for potato psyllid.

1b. Approach (from AD-416):
Identify and test possible attractants for potato psyllid. Compare attractants to standard monitoring tools under field conditions.

3. Progress Report:
The work summarized in this progress report relates to objective number 2 in the Project Plan for 018-00D: 2. Develop monitoring methods and techniques that reduce grower risk from wireworms that improve predictability of threats to potatoes; and objective number 1 in the Project Plan for 020-00D: 1. Develop monitoring methods for integrated pest management of potato insect pests. Several target chemicals potentially involved in sex attraction were tested in laboratory assays and in field trials. One compound showed significant biological activity in laboratory trials, and modest attractiveness in one field trial. Ongoing laboratory trials suggest that different populations of potato psyllid may differ in response to targeted compounds. Studies are ongoing to identify other chemicals involved in attraction, with objectives to improve effectiveness of the original targeted compound under field conditions and to determine how geographic origin of the psyllid affects response to attractants. Contributions of the University of California Riverside cooperator to the project included synthesizing all compounds targeted for assay.
