The potential of the Old World Bollworm, Helicoverpa armigera, to invade the U.S. continues to present a concern for producers of various ornamental crops, corn, cotton, and soybean. The old world bollworm is within the same genus as the already present corn earworm, Helicoverpa zea. However, the old world bollworm has shown Bt resistance.

An April 2014 article entitled “A Very Hungry Caterpillar” by Emily Unglesbee of Progressive Farm indicates that the Old World Bollworm has already cost Brazilian cotton and soybean farmers approximately $900 million since the pest’s arrival in 2012. Read the April 2014 Progressive Farm article here.

Pest biology information and the planned response by USDA-APHIS-PPQ is available through the following link:
