Thermal stress is a major driver of population declines and extinctions. Shifts in thermal regimes create new environmental conditions, leading to trait adaptation, population migration, and/or species extinction. Extensive research has examined thermal adaptations in terrestrial arthropods. However, little is known about social insects, despite their major role in ecosystems. It is only within the last few years that the adaptations of social insects to thermal stress have received attention. Herein, we discuss what is currently known about thermal tolerance and thermal adaptation in social insects – namely ants, termites, social bees, and social wasps. We describe the behavioural, morphological, physiological, and molecular adaptations that social insects have evolved to cope with thermal stress. We examine individual and collective responses to both temporary and persistent changes in thermal conditions and explore the extent to which individuals can exploit genetic variability to acclimatise. Finally, we consider the costs and benefits of sociality in the face of thermal stress, and we propose some future research directions that should advance our knowledge of individual and collective thermal adaptations in social insects.

社会昆虫对热应激的适应:最新进展和未来方向
热应激是人口下降和灭绝的主要驱动因素。热状态的变化创造了新的环境条件,导致性状适应、种群迁移和/或物种灭绝。广泛的研究已经检查了陆地节肢动物的热适应。然而,尽管社会昆虫在生态系统中发挥着重要作用,但人们对其知之甚少。直到最近几年,群居昆虫对热应激的适应才受到关注。在此,我们讨论了目前已知的群居昆虫(即蚂蚁、白蚁、群居蜜蜂和群居黄蜂)的热耐受性和热适应。我们描述了社会昆虫为了应对热应激而进化出的行为、形态、生理和分子适应性。我们研究了个人和集体对热条件临时和持续变化的反应,并探索了个人利用遗传变异来适应环境的程度。最后,我们考虑了面对热应激的社会性的成本和收益,并提出了一些未来的研究方向,以促进我们对社会性昆虫的个体和集体热适应的了解。
