2012 Annual Report

1a. Objectives (from AD-416):
The objective of this project is to develop sensitive monitoring tools that enable accurate assessment of presence, abundance, and seasonal activity of the brown marmorated stink bug (BMSB).

1b. Approach (from AD-416):
The approach to this project will be: 1) participate cooperatively with scientists at USDA-ARS, Beltsville, MD, and Virginia Tech in developing effective monitoring tools; 2) identify attractive visual stimuli that can be incorporated into a trap design; and 3) evaluate behavioral responses to candidate olfactory stimuli that can be incorporated into a trap to improve overall attractiveness in the field.

3. Progress Report:
Based on results from 2011, black pyramid traps were constructed and distributed to cooperators in nine states including WV, VA, MD, NC, NJ, PA, OR, NY, and DE. This trial will compare early season and season-long attractiveness of newly identified BMSB pheromone, commercially available methyl (2E, 4E, 6Z)-decatrieonate and unbaited traps. All traps are being deployed at the periphery of specialty or row crops bordered by natural wooded landscapes. Based on results from 2011 field and 2012 laboratory results, black pyramid traps baited with promising light-based stimuli have been built and are being deployed in the field. Three treatments are being targeted: full spectrum white, black (ultraviolet), and visible blue light. We plan to conduct field trials to document early-season attraction, species-specify and distance of response. Materials required to construct a single trap cost ~$50.00 (much lower cost than standard blacklight traps [$2,500 per unit]), though they currently require an electrical source. However, we are working with an engineering firm to determine if we can ultimately use solar panels to power these traps economically. Based on field trials conducted in Kearneysville, WV, and Beltsville, MD, the newly identified pheromone has been synthesized and being deployed in the field to document early season attraction. Thus far, traps baited with this stimulus have captured ~20x more BMSB adults than unbaited traps. Additional experiments to evaluate single isomers, dose-response and purity issues are planned. We anticipate elucidating movement patterns of adults to light-based stimuli, and adults and nymphs to olfactory stimuli in 2012, learning more about the active space of the stimuli and the periodicity of responses. In addition, patterns of movement by adults moving to and from overwintering sites are being investigated. A list of relevant literature on BMSB from Japan, Korea, and China has now been completely translated. An invited comprehensive review article is being written for submission to Environmental Entomology.
