2013 Annual Report
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.
