Behavioral responses of males of the yellow-spotted longicorn beetle, Psacothea hilaris (PASCOE), to female extracts were analyzed using a gelatin capsule as an artificial female model. Males showed dash (DS) and/or abdominal bending (AB) behaviors when exposed to a capsule coated with female extracts. When exposed to the body extracts, both DS and AB responses increased depending on the extract dose from 2^<-6>FE (female equivalent)/capsule, and the AB response decreased at high doses (1 and 2 FE/capsule). When exposed to elytra extracts, however, the AB response increased from 2^<-4>FE/capsule level but the DS response was observed only at 2 FE/capsule. These data indicate the presence of two different pheromone components : one which induces a DS response and another which induces an AB response. In follow-up experiments, the component inducing the DS response was demonstrated to be localized mainly on the prothorax surface but that inducing the AB response was distributed on the entire body surface.
