Research Project: ASIAN CITRUS PSYLLID ATTRACTANTS AND REPELLENTS

Location: Subtropical Insects and Horticulture Research

2011 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, which has delayed progress. Behavioral assays using olfactometers to investigate volatiles as attractants and repellents have also been challenging, hindering research progress. We are currently evaluating a Petri dish assay and other approaches for elucidating the chemical ecology of the psyllid.
