Incorporating Photoperiodism in Insect Phenology Models with Application to Biological Control of Weeds on Department of Defense Lands

Abstract

Biological control is an important and sustainable approach for managing widespread invasive weeds. In biological control, host specific natural enemies (usually insects) are introduced with the goal of establishing a permanent population that will provide sustained, cost-effective control of the plant. The overall goal of our project was to preserve and enhance the effectiveness of biological control for weeds, including on Department of Defense installations, through an understanding of the phenological constraints that may arise with a change in climate as a result of the insects combined responses to photoperiod and temperature. Our work applies to three important weed species that are currently (or soon to be) targets for biological control: purple loosestrife, tamarisk, and Japanese knotweed.
