Plants produce chemicals (or plant specialised/secondary metabolites, PSM) to protect themselves against various biological antagonists. Herbivorous insects use plants in two ways: as a food source and as a defence source. Insects can detoxify and sequester PSMs in their bodies as a defence mechanism against predators and pathogens. Here, I review the literature on the cost of PSM detoxification and sequestration in insects. I argue that no-cost meals might not exist for insects feeding on toxic plants and suggest that potential costs could be detected in an ecophysiological framework.
植物会产生化学物质（或植物特化/次生代谢物，PSM）来保护自己免受各种生物拮抗物的侵害。草食性昆虫以两种方式利用植物：作为食物来源和作为防御来源。昆虫可以通过解毒和将 PSM 隔离在体内作为防御机制来抵御捕食者和病原体。在这里，我回顾了关于昆虫 PSM 解毒和隔离成本的文献。我认为，对于以有毒植物为食的昆虫来说，不存在无成本的食物，并且在生态生理学框架下可以检测到潜在的成本。
