摘要：

In laboratory bioassays, whole-body homogenates and fresh cornicle wax of Rhopalosiphum padi (L.) (the bird-cherry oat aphid) elicited antennal examination and attack behavior in naive females of the polyphagous aphidiid parasitoid, Lysiphlebus testaceipes (Cresson). No such response was elicited by either homogenates or cornicle wax of Aphis nerii (Boyer de Fonscolombe) (another known host of the parasitoid) or by preparations of the aphid alarm pheromone, (E)-beta-farnesene. The response to R. padi products was independent of rearing host and appears to be innate. Application of R. padi cornicle wax to the dorsum of a nonhost aphid [Acythosiphum pisum (Harris)] increased the frequency with which this species was attacked by L. testaceipes. There was a tendency for the kairomonal activity of the cornicle secretion to decline as the wax dried, although parasitoid attack behavior was still elicited by wax which had been allowed to dry for up to 30 min before testing.
