Performance of Bt Corn Against Corn Earworm In Louisiana

Presented by: Dr. James Villegas, Assistant Professor-Field Crops Entomology, LSU AgCenter

Corn hybrids expressing pyramided Bt proteins were evaluated against corn earworms in field trials conducted in Central and Northeast Louisiana. Although non-Bt and 2nd generation Bt hybrids experienced higher ear and kernel injury than Vip hybrids, yields were generally unaffected. Corn earworms were collected for use in bioassays against commonly utilized Bt traits in corn and cotton. The implication of widespread adoption of Vip corn hybrids on corn earworm management in cotton will be discussed.
