Abstract: | The Asian longhorned beetle, Anoplophora glabripennis, is a destructive pest that attacks many species of deciduous hardwood trees. One of its natural enemies is Dastarcus helophoroides that parasitizes many species of longhorned beetles. Larval frass from six different host tree species varied in attraction to D. helophoroides adults, and frass from one host species, Acer negundo, showed no attraction at all. This information has practical benefits to evaluating the efficacy of D. helophoroides as a biological control agent for A. glabripennis and increases our understanding of the co-evolution between this parasitoid, its host, and host food trees. |
