摘要。分析了绒茧蜂雌虫的寄主发现顺序及其影响因素。一只雌性黄蜂被寄主植物（十字花科马醉木）的叶子气味所吸引。然后她慢慢地走，触角的尖端摩擦着树叶的表面。当她遇到宿主进食造成的伤害时，她的触角会抬起，转向伤害处。然后，她经常竖起翅膀和/或弯曲腹部向前，以回应寄主唾液从叶子中产生的化学物质。这种气味引起的长期搜索通常会导致与宿主毛虫相遇，因此来自宿主本身的气味会释放出对抗。宿主唾液、粪便和丝也参与了这些反应，但对新鲜叶片损伤的反应在寻找宿主的整体策略中具有最具体的功能。
ABSTRACT. The host‐finding sequence of Apanteles glomeratus females and the factors involved in it were analysed. A female wasp is attracted by the leaf odour of the food plant of the host (Pieris rapae crucivord). She then walks slowly with the tips of her antennae rubbing the leaf surface. When she comes across damage produced by the host's feeding, her antennae are raised and she turns towards the damage. She often then erects her wings and/or bends her abdomen forward in response to a chemical produced from the leaf by the host's saliva. Long‐lasting searching elicited by this odour normally leads to an encounter with a host caterpillar, whereupon odour from the host itself releases opposition. Host saliva, faeces and silk are also involved in these responses, but the response to fresh leaf damage has the most specific function in the overall strategy of host‐finding.
