Assess the ongoing value of Bt crops in controlling important pests by 1) annually estimating mortality of important pests from Bt transgenes being deployed in the major agronomic crops of Mississippi, and 2) facilitating more extensive bioassays for populations with unusual survival rates.
Insect survival and damage of natural populations will be compared using research or commercial fields of unsprayed Bt and non-Bt crops. Research will include corn earworm and tobacco budworm comparisons, as well as other pests that are targeted by transgenic crops. When greater than expected populations of large larvae are found in a Bt field, larvae will be collected and reared for further assays to test for resistance to the Bt genes.
