During the summer of 2012, 1500 semiochemical-baited detection traps targeting Anoplophora glabripennis (Asian Longhorned Beetle [ALB]) were deployed on the periphery of a large quarantine area in central Massachusetts. This large-scale survey effort provided an opportunity to investigate cerambycids other than ALB that were captured from a subset of these traps as bycatch. We captured a total of 278 cerambycids (long-horned beetles) representing 39 species during 3 months of trapping; Graphisurus fasciatus, Brachyleptura rubrica, Astylopsis macula, Aegomorphus modestus, and Elaphidion mucronatum (long-horned beetles) were the most abundant. The data presented here indicate that pest-detection activities involving semioehemieal-baited traps provide an important opportunity to survey non-target insects.
