Parasitic wasps use a broad spectrum of different stimuli for host location and host acceptance. Here we review the published evidence for the use of mechanical stimuli, i.e. substrate born vibrations which are invariably regarded as vibrotaxis. We propose a set of criteria to class behavioural reactions as vibrotaxis or vibrokinesis and characterize 14 studies reporting the use of host-associated vibrations by parasitoids. The studies are compared concerning (i) experimental design; (ii) characterisation of vibrational signals; and (iii) progress of the parasitoid towards the host.The recent experimental development based on new measurement techniques shows the growing body of evidence that host-associated vibrations are exploited by parasitic wasps. Nevertheless a definite proof for vibrotaxis is still lacking. To assess the exact mechanisms by which parasitoids use vibrations bioassays comparing reactions to natural and artificially generated signals are needed. Vibrotaxis as well as vibrokinesis are both helpful host location strategies for parasitoids foraging in a multimodal environment. At the community level they may lead to niche differentiation.
寄生蜂利用多种不同的刺激来定位宿主并接受宿主。在此，我们回顾已发表的关于利用机械刺激的证据，即源自基质的振动，这种振动一直被视为趋振性。我们提出了一套标准，用于将行为反应归类为趋振性或振动性运动，并对14项报告寄生蜂利用与宿主相关振动的研究进行了特征描述。对这些研究在以下方面进行了比较：（i）实验设计；（ii）振动信号的特征描述；以及（iii）寄生蜂向宿主移动的过程。基于新测量技术的最新实验进展表明，越来越多的证据表明寄生蜂利用与宿主相关的振动。然而，仍缺乏趋振性的明确证据。为了评估寄生蜂利用振动的确切机制，需要进行生物测定，比较其对自然信号和人工产生信号的反应。趋振性以及振动性运动都是寄生蜂在多模态环境中觅食时有用的宿主定位策略。在群落水平上，它们可能导致生态位分化。
