Colorado potato beetle: Factors affecting pheromone communication and behavioral control

Sunday, November 10, 2024
8:24 AM – 8:36 AM MST
Location: Phoenix Convention Center, 225 A, PCC
Oral Presentation
Several factors affect attraction of Colorado potato beetle (Leptinotarsa decemlineata) males and females to the male-produced aggregation pheromone, decemdiol, and to the yet-unidentified female-produced sex pheromone. These include associated host plant, life history of the mature males, and number of males and/or females present. With the synthetic decemdiol, enantiomeric purity and dose are also decisive for efficacy. Successful deployment of behavioral control tactics using synthetic decemdiol will depend on beetle responses to spatiotemporal distribution of pheromone, as well as the economics of synthesis and formulation quantity and quality. We summarize several of our recent experiments on border deployment, dose and purity, and demonstration of attraction to live male and female beetles in the field.
