Cooperative Agricultural Pest Survey (CAPS) 
The Cooperative Agricultural Pest Survey (CAPS) is a national pest detection program funded through a cooperative agreement between the Maine Department of Agriculture, Conservation and Forestry, Division of Animal and Plant Health and the U.S. Department of Agriculture, Animal and Plant Health Inspection Service (USDA-APHIS).
The goal of the program is to provide an early warning system for pest detection and response that is critical for protecting our nation's agricultural and natural resources. Typical surveys target exotic and invasive pests and pests of export significance.
