2012 Annual Report 1a.Objectives (from AD-416): To discover and identify attractants and repellents of the Asian citrus psyllid with the ultimate goal of finding volatiles that could be used in a pest management program for the psyllid. 1b.Approach (from AD-416): Volatiles from plants will be screened in the laboratory for attraction and repellency using y-tube olfactometers, four-arm olfactometers, wind tunnel assays, and EAG/EAD. 3.Progress Report: This project is related to Objective 3c: Investigate basic biology and ecology of the Asian citrus psyllid and its natural enemies in Florida citrus. Research continued on evaluating various volatiles as attractants and repellents for the Asian citrus psyllid. Conducting electro-antenna-grams with the psyllid has been challenging and difficult, but much progress has been made on these analyses and several chemicals which elicit antenna responses have been identified. Behavioral assays to investigate volatiles as attractants and repellents have also been challenging, hindering research progress. We are currently evaluating wind tunnel assays for elucidating the chemical ecology of the psyllid.
