Abstract
Subcortical beetles interact with a wide range of semiochemicals released from different sources, including trees, fungi, and insect pheromones. While the attraction of bark beetles, their insect predators, and competitors to bark beetle pheromones is well-studied, the attraction of these beetle communities to other sources of semiochemicals remains poorly understood. We tested the attraction of bark and wood-boring beetles and their predators to host stress volatiles, fungal volatiles, and a mountain pine beetle lure in the field. Host stress volatiles were derived from lodgepole pine trees stressed by three fungal symbionts of mountain pine beetle and two common phytopathogens. Our results showed that bark beetles, particularly mountain pine beetles, show a preference for a combination of fungal volatiles, particularly 2-methyl-1-butanol and mountain pine beetle lures. Without the addition of lures, 2-methyl-1-butanol was also identified as a key fungal volatile in the attraction of mountain pine beetle competitors from the Cerambycidae and Buprestidae families. Predators in the Elateridae and Staphylinidae families showed attraction to host stress volatiles and the healthy tree volatile profile. These findings suggest that these chemicals warrant further field testing for potential use in monitoring and management of subcortical beetle populations.
