1. Chambers, Benjamin D. Factors Influencing Behavior of Overwintering Brown Marmorated Stink Bugs (Halyomorpha halys) in Human Dwellings.

Degree: MSin Life Sciences, Entomology, 2017, Virginia Tech

The brown marmorated stink bug (Halyomorpha halys) is known for overwintering in human homes. This research investigated the responses of these bugs to some characteristics of overwintering structures, including crevice tightness preference, light sources, and dead bugs leftover from previous years. Tightness experiments indicated that bugs in crevices with hard walls prefer to settle in spaces between 4.5 and 5.5 mm high. Bugs also tended to stay on the floor, go back as far as they could, and face the entrance of the crevice. These findings will help improve overwintering box designs for collection and research, and will help pest control professionals focus their efforts. When bugs were disturbed and exposed to common household light bulbs, they tended to move toward the bulbs in late summer and in spring, but responded less in fall and winter, and responded more often in the afternoon than at night. Bugs were also exposed to other dead bugs in several ways. When lone bugs were exposed to groups of dead bugs from previous years, they went to them only if they could touch them. Single dead bugs had less of an impact. Exposure to groups of dead bugs from the same year drove live bugs away. Overwintering brown marmorated stink bugs do not appear to eat other bugs that have recently died. These results suggest several possible improvements to the designs of trap shelters used for research and control. Advisors/Committee Members: Kuhar, Thomas P. (committeechair), Leskey, Tracy C.
