Abstract

Here, we describe several field experiments that evaluated potential problems with current methods of trapping cerambycid beetles using panel traps baited with synthesized pheromones. Positioning traps at least 5 m apart in linear transects was effective in preventing unbaited traps from intercepting beetles that were flying to baited traps, which would result in interference between treatments. There was no evidence that traps baited with a strong attractant drew beetles away from traps baited with weaker attractants, which would lead to the erroneous conclusion that the latter have no activity. Unbaited panel traps were minimally attractive to cerambycid beetles, and unlikely to intercept them passively in flight. Finally, dose-response experiments revealed that trap catch of cerambycids was positively associated with pheromone release rates. Overall, our results generally validated current methods of trapping cerambycids using traps baited with pheromones.
