Upwind flight response of the bark beetle predator Thanasimus dubius towards olfactory and visual cues in a wind tunnel

摘要

1The checkered beetle Thanasimus dubius (Fabricius) (Coleoptera: Cleridae) is a common predator in North America that feeds on bark beetles (mostly Ips and Dendroctonus spp.) (Coleoptera: Curculionidae: Scolytinae). Despite numerous field-trapping studies on this predator, the response of individual T. dubius to bark beetle pheromones, host tree volatiles and visual stimuli has seldom been studied in the laboratory.
