Abstract: Objectives 1. To determine where army cutworm moths (Euxoa auxiliaris) (ACMs) originate using genetic markers. Pressures on ACM subpopulations, either natural (e.g., weather patterns) or man-caused (e.g., presticides), may affect moth recruitment and the numbers of adults reaching high elevation sites where they are a critical food source for the threatened GYE grizzly bear (Ursus arctos horribilis) 2. To determine whether ACMs harbor pesticides in their tissues. Resulting pesticide magnification in grizzly bears that forage heavily on moths may have detrimental physiological side effects. 3. To determine whether ACMs from different Great Plains origins are interbreeding in high elevation sites prior to their return to agricultural areas. If ACM subpopulations do not interbreed, unfavorable conditions in specific Great Plains areas may impact moth numbers in high elevation. Findings and Status Ongoing research.
