The Illinois Cooperative Agricultural Pest Survey (CAPS) program is a joint effort between several state and federal agencies, including the Illinois Natural History Survey, Illinois Department of Agriculture, and USDA-APHIS-PPQ.

This program focuses on the early detection and surveillance of harmful or economically significant exotic plant pests, diseases, and weeds that have eluded first-line of defense inspections or have been identified as threats to U.S. agriculture and/or the environment.

The primary objective of the CAPS program is to safeguard our nation’s food and environmental security from invasive pests that threaten our production and ecological systems.
