The ‘choice’ of whether to enter diapause or to develop directly has profound effects on the life histories of insects, and may thus have cascading consequences such as seasonal morphs and other less obvious forms of seasonal plasticity. Present knowledge of the control of diapause and seasonal morphs at the physiological and molecular levels is briefly reviewed. Examples, mainly derived from personal research (primarily on butterflies), are given as a starting point with the aim of outlining areas of research that are still poorly understood. These include: the role of the direction of change in photoperiod; the role of factors such as temperature and diet in modifying the photoperiodic responses; and the role of sex, parental effects and sex linkage on photoperiodic control. More generally, there is still a limited understanding of how external cues and physiological pathways regulating various traits are interconnected via gene action to form a co‐adapted complete phenotype that is adaptive in the wild despite environmental fluctuation and change.

蝴蝶和其他昆虫滞育和季节性变形的诱导:已知、未知和整合的挑战

进入滞育期还是直接发育的“选择”对昆虫的生活史有着深远的影响,因此可能会产生连锁后果,例如季节性变形和其他不太明显的季节性可塑性形式。简要回顾了目前在生理和分子水平上控制滞育和季节性形态的知识。示例主要来自个人研究(主要是关于蝴蝶),作为起点,旨在概述仍然知之甚少的研究领域。其中包括:光周期变化方向的作用;温度和饮食等因素在改变光周期反应中的作用;以及性别、亲代效应和性别连锁对光周期控制的作用。更普遍,
