In the complex life cycles of helminths, life in intermediate hosts poses special problems not covered by standard life history strategy theory. While under selection to reduce mortality and to increase growth, there is the additional problem of transmission between hosts. This review attempts to harmonise classical knowledge of the overall life cycle patterns with recent evolutionary theory as to how larval helminths exploit intermediate host tissues and avoid the gut to maximise fitness in terms of growth and mortality. It also considers the evolutionary rules by which trophically transmitted larvae are expected to increase their transmission rates to the next host.
在寄生虫的复杂生命周期中，中间宿主的生活带来了标准生活史策略理论未涵盖的特殊问题。在受到选择以降低死亡率和增加生长的同时，还存在宿主之间传播的额外问题。本综述试图协调经典的整体生命周期模式知识与最近的进化理论，了解幼虫期寄生虫如何利用中间宿主组织并避免肠道以最大限度地提高生长和死亡率方面的适应性。它还考虑了营养传播的幼虫预计会增加其向下一宿主传播率的进化规则。
