昆虫寄生线虫的感染性阶段青少年在家庭斯氏线虫寻找主机使用的策略，从伏击巡航觅食。感染性幼虫通过站立在它们的尾巴上并在站立或跳跃时直接接触昆虫来附着于经过的昆虫。我们确定了不同程度的伏击觅食专业化的物种在不同的信息来源的行为反应不同。机械接触，空气运动，和主机相关的挥发性线索的跳跃行为的一些物种的斯氏线虫的重要触发器。三种伏击觅食蜂（S. carpocapsae，S. scapterisci和S. siamkayai）通过增加挥动和跳跃行为来响应小的空气运动，并且跳跃方向偏向于运动的来源。对于鼠伤寒沙门氏carpocapsae和S.与寄主相关的挥发性线索是诱发跳变的强烈诱因，但寄主线索并没有增加S.暹罗跳。与此相反，两个中间觅食物种，S。ceratophorum和S. Monticilli，没有表现出可检测到的反应，无论是空气运动或主机线索。
The infective stage juveniles of insect parasitic nematodes in the family Steinernema search for hosts using strategies ranging from ambush to cruise foraging. Infective juveniles attach to passing insects by standing on their tails and contacting an insect directly when standing or by jumping. We determined how species with differing degrees of ambush foraging specialization differ in their behavioral responses to different sources of information. Mechanical contact, air movement, and host associated volatile cues were important triggers of jumping behavior for some species of Steinernema. Three species that are ambush foragers (S. carpocapsae, S. scapterisci, and S. siamkayai) responded to small air movements by increased waving and jumping behavior, and jumps were directionally biased towards the source of the movement. For S. carpocapsae and S. scapterisci, host-associated volatile cues were strong triggers to jump, but host cues did not increase the proportion of S. siamkayai jumping. In contrast, two intermediate foraging species, S. ceratophorum and S. monticolum, did not demonstrate a detectable response to either the air movement or the host cues.
