The objective of this project is to develop and deliver sustainable management programs for brown marmorated stink bug (BMSB).
Obj. 1) To understand the landscape and environmental factors that affect BMSB populations, we will first develop a nationwide monitoring network. In each region we will use pheromone baited traps placed in specialty crops to conduct bi-weekly monitoring of BMSB populations throughout the growing season. The crops that will be monitored will vary by region based on the known (or expected in areas as yet invaded) hosts of BMSB. Sampling will be conducted at 30 or more field sites in each region per year. Pheromone baited traps will also be used to sample population dynamics of BMSB in row crops (e.g., cotton, corn, alfalfa, peanut), forests, and urban areas that are known hosts of BMSB and nearby specialty crop fields. Obj. 2) To determine important natural enemies of BMSB and further develop biological control approaches, we will conduct sampling across the country. We will conduct field surveys throughout each field season of the project to detect and document the identity and species composition of native parasitoids and predators that attack BMSB in different specialty crops and landscape reservoir habitats. Surveys will be conducted in different habitats using laboratory-reared sentinel egg fresh or frozen masses and wild-collected BMSB egg masses. Recovered parasitoid specimens will be identified morphologically.
