蚜小蜂Lysiphlebus cardui寄生在蚂蚁照顾的Aphis fabae cirsiiacanthoprotein殖民地，而不会引起蚂蚁Lasius尼日尔的攻击行为。相比之下，另一种蚜虫寄生蜂Trioxys angelicae则被蚂蚁迅速识别并大力攻击。L.尼日尔工人对L. cardui和T.天使。死湖红腹小蜂在遇到L.尼日尔，而死T.发现它们的蚂蚁会立即抓住它们。然而，己烷洗涤寄生虫引起了类似的反应模式的蚂蚁，在这两个蚜虫物种被容忍的蚜虫殖民地。引诱实验表明，角质层上的化学刺激是蚂蚁区分寄生蜂的主要线索。L. cardui转移到洗过的T. angelicae导致蚂蚁对L. cardui和L.尼日尔工人表现出典型的去除模式，他们通常显示对T。angelicae时，T.当归提取物对L. cardui个人。两种寄生蜂均能被A.用与蚜虫对照个体类似的蚂蚁处理蚕豆。因此，本文提出了蚜虫小蜂L.讨论了CARDUI使用化学模拟。
The aphidiid wasp Lysiphlebus cardui parasitizes in ant-attended Aphis fabae cirsiiacanthoidis colonies without causing aggressive behavior in the ant Lasius niger. By contrast, Trioxys angelicae, another aphidiid parasitoid of aphids, is rapidly recognized and vigorously attacked by the ants. L. niger workers also responded differently to dead individuals of L. cardui and T. angelicae. Dead L. cardui parasitoids were often ignored when encountered by L. niger, whereas dead T. angelicae individuals were immediately grasped by ants that discovered them. However, hexane-washed parasitoids caused a similar reaction pattern in the ants, in that both aphidiid species were tolerated in the aphid colony. Lure experiments demonstrated that chemical stimuli on the cuticle are major cues for the ants to distinguish between the parasitoids. The hexane extract of L. cardui transferred to washed individuals of T. angelicae resulted in ant responses characteristic towards L. cardui, and L. niger workers displayed the typical removal pattern they normally showed towards T. angelicae when T. angelicae extract was applied to L. cardui individuals. Both parasitoid species treated with the hexane extract of A. fabae cirsiiacanthoidis were similarily treated by the ants as were aphid control individuals. The suggestion that the aphidiid wasp L. cardui uses chemical mimicry is discussed.
