Dastarcus helophoroides (Fairmaire) (Coleoptera: Bothrideridae) is an important natural enemy of longhorned beetles (Coleoptera: Cerambycidae). It is distributed throughout most Provinces in China. We investigated whether there were differences among D. helophoroides populations collected from different hosts in different geographic locations. Results showed that different D. helophoroides populations displayed different olfactory responses to larval frass from different longhorned beetle species. All populations were significantly attracted to the frass of their original hosts. Parasitism rates of different populations also varied when supplied with host larvae of the same longhorned beetle species. These results indicate that the three D. helophoroides populations tested differed in host-related behaviors. Therefore, the population of D. helophoroides must be taken into consideration when implementing biological control programs for different species of longhorned beetle.
