The dynamics of cotton insect pests is changing from a weevil/worm management system to the bug complexes. The total of loss and cost of control for insects in the 2009 U.S. cotton crop amounted to $491 million. Lygus, or plant bug, was the most damaging pest, infesting 53 percent of all acreage. Other major pests include thrips, bollworms, stink bugs, fall armyworms and spider mites. In the central part of the Mid-South, considered the hot spot for the tarnished plant bug, cotton producers can make 10 to 12 applications a year for the pest. Bt cottons are expected to further reduce the impact of caterpillar pests, while bugs are going to continue to rise in importance.
