Conducting basic and applied research in areas of insect molecular biology and toxicology, including resistance to insecticides in southern row crop pests to further improve chemical/biorational control of field crop pests in the Mid South. Research emphasis is placed particularly on the tarnished plant bug and the bollworm/budworm complex; and with equal or less emphasis on other insects of cotton, corn, and other
Research objectives are to: 1) develop fundamental information on the molecular and biochemical basis for insecticide resistance to Bt, organophosphates, pyrethroids, and other novel insecticides in pests of row crops; 2) develop PCR/DNA-based techniques for monitoring resistance gene frequency in field populations; 3) examine the modes of action for bioactive compounds with potential insect control properties; and 4) utilize the results in objectives 1-3 to improve, develop and integrate insect suppression strategies into systems that minimize the cost of plant protection and yet are economically and ecologically acceptable. Specific objectives will include but are not limited to cloning and characterization of candidate genes (including P450 monooxygenases, esterases, glutathione S-transferases, sodium channel, acetylcholine esterase, proteinases, aminopeptidases, cadherins, alkaline phosphatases, etc.) responsible for insecticide resistance, and developing molecular and biochemical techniques for detecting and suppressing resistance in target insect populations.
