2011 Annual Report
The attraction/repellency of Asian citrus psyllid to a blend of volatiles primarily from guava was evaluated. There was some evidence the psyllid was attracted to the blend in four-arm olfactometer studies, but this attraction could not be confirmed in vertical Y-tube olfactometer experiments. Five constituents of the blend are being evaluated to determine if they elicit antennal responses by males and females. A number of volatiles associated with citrus have been identified that elicit antennal responses, and we have requested pure samples of these from the cooperator for further testing.
Progress was monitored through direct involvement in lab and field activities, research meetings, and discussions with collaborators at U.S. Horticultural Research Laboratory (USHRL) and Animal and Plant Health Inspection Service - Plant Protection Quarantine (APHIS-PPQ), telephone calls and email communications.
