Purpose. The project team will pro-actively address significant
threats of whitefly resistance to several key selective insecticides in our multi-crop
system. Our innovative outreach approach uses spatial chemical use maps we develop
from agricultural pesticide use reporting data to support and inform pest manager
insecticide use decisions based on pesticide use patterns and probabilities of resistance
development. We will test spatial hypotheses about the relationship of prior chemical
use to development of resistance in whiteflies by sampling whiteflies from target
areas (high-use or low/no-use) and testing for resistance. Finally, we will measure
changes in awareness, knowledge, skills, behavior and condition with respect to
resistance status, chemical use practices and landscape concepts in resistance management.
