Project Number: 8042-22000-315-11-S
Project Type: Non-Assistance Cooperative Agreement
Start Date: May 30, 2020
End Date: Jul 31, 2021
Identify the attractants (sex/aggregation pheromone/kairomone) used by peanut burrower bug, synthesize the potential pheromone components, develop a trap for monitoring pest populations, and conduct preliminary field test.
NEA will investigate the attraction of peanut burrower bug to volatiles. The headspaces of male and female bugs and peanut seeds will be collected, coupled gas chromatography - electroantennographic detection (GC-EAD) will be conducted to select electrophysiological active compounds, gas chromatography - mass spectrometry (GC-MS) will be performed to identify the potential compounds, and field tests will be carried out to evaluate the activity of identified semiochemicals. If the interested compounds are not commercially available, they will be synthesized in the Invasive Insect Biocontrol and Behavior Laboratory (IIBBL). Once attractants identified, different formulations will be developed and release rates will be measured. Finally, optimized dispensers will be prepared in IIBBL and sent to collaborators for their field activity evaluations.
