Abstract

In 2006, we evaluated the effects of combining lures releasing pine host kairomones (ethanol α-pinene) with lures releasing bark beetle pheromones (ipsenol ipsdienol) on trap catches of predators associated with bark and woodboring beetles in Florida, Georgia, Louisiana, and Virginia. Catches in traps baited with all 4 compounds were greater than those in traps baited with either binary blend for the common predators Thanasimus dubius (F.) (Coleoptera: Cleridae), Temnoscheila virescens (F.) (Coleoptera: Trogossitidae), Aulonium tuberculatum LeConte (Coleoptera: Zopheridae), and Lasconotus spp. (Coleoptera: Zopheridae). The same was true for: Enoclerus nigripes (Say) (Coleoptera: Cleridae) at 2 of 3 locations; Platysoma cylindricum (Paykull) (Coleoptera: Histeridae) at 3 of 4 locations; and Corticeus spp. (Coleoptera: Tenebrionidae) at 2 of 6 locations. In contrast, the addition of ethanol α-pinene to traps baited with ipsenol ipsdienol reduced catches of Platysoma attenuatum LeConte (Coleoptera: Histeridae) at 2 of 4 locations.
