Moth Identification Guide for Blacklight Trap Catch in Wisconsin -UW Extension Publication A3855
Blacklight trap captures provide information on regional activity of Lepidoptera ("caterpillar" pests) of economic concern in field and sweet corn, soybeans and small grains. Blacklight trap catch allows pest managers to keep ahead of developing insect pest populations by monitoring adult moth flights. UWEX Publication A3855 features photographs of 16 field crop Lepidoptera insect pests in the adult (moth) stage. A simple key features identifying characteristics, moth size, and a calendar timeline for each moth flight in Wisconsin. Tips on operating and sorting catch from blacklight traps are included.

Insect Resistance Management and Refuge Requirements
for Bt Corn -UW Extension Publication A3857
Planting a refuge is required by the U.S. Environmental Protection Agency as a condition of Bt corn registration and to preserve usefulness of Bt traits. Refuge corn acres do not contain the Bt trait used in the main planting. An insect resistance management (IRM) plan maintains Bt susceptible insect populations by way of a refuge. The refuge must be planted to 20% of corn acreage on each farm where Bt corn is planted, and there are specific configuration and distance requirements for planting the refuge. Publication A3857 answers frequently asked questions about IRM and refuge requirements for Bt corn and outlines steps to meet this requirement on farm. (PDF or order a hardcopy)

Western Bean Cutworm: A Pest of Field and Sweet Corn
-UW Extension Publication A3856

As this pest will likely become established after arrival in a state, it is important that growers and agricultural professionals know how to identify and manage it. UWEX Publication A3856 explains WBC appearance, life cycle, corn scouting protocols, economic thresholds, and management options including: biological and natural controls, chemical control, and the importance of insect resistance management when using transgenic Bt corn hybrids for WBC management.
