2013 Annual Report

1a. Objectives (from AD-416):
Identify repellents or attractants that could be used to manage the Asian citrus psyllid.

1b. Approach (from AD-416):
Cooperator will provide ARS with various guava essence fractions, which ARS will screen for repellency or attractancy to the psyllid using olfactometer and EAD/EAG studies. Cooperator will further fractionate active fractions, and ARS will screen these as well. The chemical nature of any repellents or attractants found will be determined, if possible.

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. The attraction/repellency of Asian citrus psyllid to a blend of volatiles primarily from citrus was evaluated. A number of volatiles associated with citrus have been identified that elicit antennal responses, and we currently studying pure samples of these for their effect on psyllid behavior.
