MISSION STATEMENT AND STAFF: SOUTHERN INSECT MANAGEMENT 4 Conduct basic biological and ecological RESEARCH UNIT research on plant bugs, particularly the ARS/USDA, Mid South Area tarnished plant bug, Lygus lineolaris, P. O. Box 346 cotton aphid, Aphis gossypii, and the Stoneville, Mississippi 38776 silverleaf whitefly, Bemesia argentifolii. Telephone: 601-686-5231 FAX: 601-686-5421 Develop monitoring and _ predictive technology through quantitative MISSION: population ecology for field crop insect pests, particularly bollworm/budworm, To develop new knowledge on the biology of tarnished plant bug, and cotton aphid. field crop insects for development of new and improved control tactics and to establish Assess the role of early season host plants fundamental principles for encouraging and in the buildup of Heliothis/Helicoverpa, using natural enemies more effectively. To beet armyworm, and tarnished plant bug develop and integrate insect suppression populations and devise new and strategies into field crop and pecan systems innovative tactics for suppressing these that minimize the cost of plant protection, yet populations, including use of are ecologically acceptable. Specifically: entomopathogenic viruses in area-wide management of these pests. 1. Elucidate the efficacy of indigenous predators and parasites, particularly those Develop chemical/biorational control attacking the bollworm, Helicoverpa zea, tactics for use in integrated systems. and tobacco budworm, Heliothis virescens. . Develop chemical, biological, and other nonchemical methods for control of insect 2. Research and develop methods for and mite pests of pecans. Evaluate augmenting parasite populations in selections and native pecans for yield and management of insect pests of field crops, adaptability to the mid-south. particularly parasitoids for control of Heliothis/Helicoverpa. Monitor for Bt resistance and develop resistance management tactics. 3. Develop new knowledge on biology and behavior of Heliothis/Helicoverpa spp. 10. Locate, develop, and evaluate soybean and beet armyworm, including use of cultivars resistant to insects. entomopathogenic viruses in management of the latter. a a om a ; 7 7 - +7 ~: . te TR MA TAEMSTATS Veta Af ut.
