Insect Trapping Program

The University of Delaware’s Extension IPM Program provides in-season insect  trap information to help producers, agribusiness and consultants make informed insect management decision in field and vegetable crops.

Traps are monitored twice a week and current trap catches are posted  on this website. The main pests monitored include corn earworms (CEW) , European corn borers (ECB), and true armyworm (TAW), and stink bugs.

Attention: The first trap catch for the 2018 season will be on April 30th.
