植食性昆虫和寄生蜂的化学感受反应和生理耐受性的变化可能导致新的寄主协会。这些变化的起源在生态和进化的时间被认为是。化学遗产假说假设幼虫化学感受环境对成虫化学感受反应的影响不依赖于（或不仅依赖于）持续的神经变化（“记忆”），而是依赖于昆虫体内或体外的化学线索的痕迹，这些线索影响成虫的行为，可能特别是在与成虫出现或孵化有关的“敏感期”。早期阶段遗留的化学线索可能会通过降低外周敏感性来影响成虫或幼虫。根据剂量反应曲线的形式，这种变化可能会减少厌恶或增加对先前威慑刺激的积极反应。注意力被提请这种行为诱导和诱导解毒酶之间的可能联系。如果暴露于宿主化感物质影响昆虫对杀虫剂的反应，这种联系可能具有实际意义，反之亦然。来自父母的化学信号对个体化学感受反应的影响很难与遗传效应区分开来。化学遗产假说的一些可检验的假设进行了鉴定。
Changes in the chemosensory responses and physiological host tolerance of phytophagous insects and parasitoids may result in new host associations. The origin of those changes in ecological and evolutionary time are considered. The chemical legacy hypothesis postulates that effects of larval chemosensory environment on adult chemosensory responsiveness depend not (or not only) on persistent neural changes (''memory''), but on traces of chemical cues inside or outside the insect''s body, which influence adult behavior, perhaps particularly during a ''sensitive period'' associated with adult emergence or hatching of the egg. Chemical cues bequeathed by earlier stages may affect adults or larvae by reducing peripheral sensitivity. Depending on the form of the dose-response curve, this change could decrease aversion or increase a positive response to a previously deterrent stimulus. Attention is drawn to a possible link between this behavioral induction and the induction of detoxification enzymes. This link might be of practical importance if exposure to host allelochemicals were to influence insects'' responses to insecticides, and vice versa. An influence on the chemosensory responsiveness of an individual by chemical cues derived from its parents would be hard to distinguish from a genetic effect. Some testable postulates of the chemical legacy hypothesis are identified.
