Differences in the distribution of parasitized and unparasitized hosts has been used to infer modification of host behavior by insect parasitoids. Data are presented showing that not only do parasitized hosts behave differently from unparasitized ones, but that the behavior of parasitized hosts varies in function of the physiological state of the parasitoid. Aphids containing nondiapausing parasitoids leave the aphid colony and mummify on the upper surface of the leaves, whereas those containing diapausing parasitoids leave the host plant and mummify in concealed sites. Modification of host behavior by diapausing parasitoids results in the selection of a suitable microhabitat that reduces the incidence of hyperparasitism and should decrease the action of adverse climatic conditions during the lengthy dormant period.
寄生虫和未寄生虫宿主的分布差异被用来推断昆虫寄生蜂对宿主行为的改变。本文介绍的数据表明，不仅寄生虫宿主的行为与未寄生虫宿主不同，而且寄生虫宿主的行为还随寄生蜂的生理状态而变化。含有非滞育寄生蜂的蚜虫离开蚜虫群体，在叶片的上表面变成木乃伊，而含有滞育寄生蜂的蚜虫则离开宿主植物，在隐蔽的地方变成木乃伊。滞育寄生蜂对宿主行为的改变导致了合适的微生境的选择，从而降低了重寄生的发生率，并应该减少在漫长休眠期内不利气候条件的影响。
