Research Interests

Current research projects focus on the ecology, biology, and sustainable management of exotic invasive pests, sugarcane aphid, Melanaphis saccharis (Zehntner) (Hemiptera: Aphididae), and brown marmorated stink bug, Halyomorpha halys Stål (Hemiptera: Pentatomidae), in agroecosystems. An important aspect of this research includes an understanding of the efficacy and ecological requirements of natural enemies attacking these pests to support biological control efforts. Past research projects examined the potential of soybean host plant resistance in the pest management of kudzu bug, Megacopta cribraria (Fabricius) (Hemiptera: Plataspidae), and the determination of mechanisms of such resistance. The overwintering refuge utilized by kudzu bug was also examined. Other major research projects include the understanding of nutritional and overwintering requirements of a native stink bug egg parasitoid, Telenomus podisi Ashmead (Hymenoptera: Platygastridae).
