2013 Annual Report
1a.Objectives (from AD-416):
To develop a push-pull system for Asian citrus psyllid management for protection of young citrus plants.
1b.Approach (from AD-416):
Investigate visual cues that cause attraction and repellency of psyllids in the laboratory, devise push and pull methods for psylids and evaluate the methods in the field with young citrus plants.
This research relates directly to Objective 2. Detection and attraction: Develop chemical and acoustic detection and attraction systems for pest species and natural enemies: specifically develop trapping systems using floral-derived volatiles to monitor and/or eliminate pest populations and monitor dispersal of augmented parasitoids, detect acoustic signals produced by cryptic/hidden pests for targeted control, and improve detection efficiency through automation.
The asian citrus psyllid is the vector of the most devastating citrus disease worldwide with few effective measures available for surveillance and control of the insects. Progress on this newly-initiated project entails routine collection of psyllids from commercial and university groves in Immokalee using suction and interception traps. These collections are then provided to ARS/Gainesville for identification and measurements. Research results on reflective mulches for psyllid repellency are made available to ARS/Gainesville for optimization of pull methodology.
