Description:

Pest and natural enemy ecology play a key role in our development of integrated pest management tactics in today’s agriculture. We can produce better suites of management tools in crops by leveraging knowledge of pest movement, plant-insect interactions, and community ecology. For example, increasing crop genotypic diversity is a promising strategy for managing insect pests via a combination of top-down and bottom-up effects on pests. Using a combination of systems (soybeans and wheat), I demonstrate that variety mixtures of crops can produce multitrophic effects in crop systems. For mobile pests, how they interact with non-crop hosts can shape pest population dynamics at the landscape level and drive when pest issues arise. I investigate the role of non-crop habitat for bagrada bug population dynamics in California’s Salinas Valley. Growers may also exploit movement ecology and host preference of the bagrada bug via trap crops to reduce damage to focal crops. In California’s orchard crops, pest management has relied on IPM, but still provides many opportunities for ecologically informed management of pests, including both endemic and invasive pests. I will also present my vision for extension and the extension component of the orchard crop IPM position.
