Soybean loopers are highly resistant to most insecticides, and few products exist for its control. As insecticide applications have increased for stink bugs, soybean looper populations have flared. The problem has become more serious since soybean loopers can attack other and several weeds. Increases in herbicide-resistant Palmer amaranth and morning-glory have further increased the problem. This project is directed at developing information to better clarify the effects of herbicide-resistant weeds on soybean looper population growth and insecticide resistance. It intends to determine Palmer amaranth and morning glory effects on soybean looper ecology and determine herbicide-resistant Palmer amaranth and herbicide-tolerant morning-glory effects on soybean looper insecticide resistance.
