Camphor: An attractant for the cupreous polished chafer, Protaetia pryeri pryeri (Janson) (Coleoptera: Scarabaeidae)

抄録

Adults of cupreous polished chafer Protaetia pryeri pryeri (Janson) (Coleoptera: Scarabaeidae) were attracted by and landed on cotton balls treated with commercially available pet deodorant spray or a topical antipruritic for human skin. When volatiles from the spray and antipruritic were extracted by solid phase microextraction (SPME) and analyzed by GC-MS, camphor was found as a common compound. This compound was not detected in the volatiles of two other commercially available deodorant sprays, neither of which attracted chafers. In the field, P. p. pryeri were attracted to cotton balls treated with 63 μg to 4 mg (1R)-camphor but not to untreated balls. This demonstrated that (1R)-camphor is an attractant for P. p. pryeri. The adaptive significance of the response to camphor by P. p. pryeri is discussed.
