在寄生虫的生命周期中，传播事件，即寄生虫从“上游”宿主传播到“下游”宿主的过程，通常涉及行为适应，导致寄生虫实际传播的机会增加。这些行为源于寄生虫基因组的进化变化：要么寄生虫选择对来自下游宿主或其生活环境的刺激做出反应(它们自己的反应或它们在上游宿主中激发的反应)，要么它们选择针对下游宿主的刺激(来自它们自身或从上游宿主引发的改变)。根据行为适应的不同，对不同的过程进行了区分，并用实例加以说明。难以证明这些特征实际上是有利于传递的选择性过程的结果，并讨论了几个悬而未决的问题。
In parasitic life cycles, transmission events, that is, the passage of a parasite from an "upstream" host to a "downstream" host, often involve behavioral adaptations that result in an increase of the chances of the parasite's being actually transmitted. These behaviors stem from evolutionary changes in the parasites' genomes: either the parasites select responses (their own responses or those they provoke in upstream hosts) to stimuli arising from downstream hosts or from the environment where they live, or they select stimuli (arising from themselves, or from alterations they provoke in upstream hosts) that are addressed to downstream hosts. The various processes are differentiated on the basis of behavioral adaptations and illustrated by examples. The difficulty of demonstrating that the traits are actually the result of a selective process favoring transmission and several unresolved questions are discussed.
