title: An allelochemical elicits arrestment inApanteles kariyai in feces of nonhost larvaeAcantholeucania loreyi.
abstract: Females of the larval parasitoidApanteles kariyai (Watanabe) (Hymenoptera: Braconidae) are arrested on fecal pellets ofAcantholeucania loreyi (Duponchel) (Lepidoptera: Noctuidae) larvae. Upon subsequent antennal contact with anA. loreyi larva, females sting it with their ovipositor. However, such stinging did not result in any offspring. The allelochemical involved in feces has been identified and is identical to a kairomone of the hostPseudaletia separata (Lepidoptera: Noctuidae). In contrast toA. loreyi, P. separata is a suitable host forA. kariyai, and oviposition inP. separata results in offspring production. The allelochemical mediating the interaction betweenA. loreyi andA. kariyai is discussed in the context of current allelochemical terminology.
