假死是昆虫重要的防御行为，与生存策略密切相关。昆虫受到天敌或类似天敌的外部物理刺激时，足、触角等附肢收缩，强直静止，自发进入假死状态。近年来，与昆虫假死行为相关的研究逐渐增多，进展明显，明确了多种昆虫假死的发生时间、发生频率、刺激方式和诱发因素等特征，涉及臭椿沟眶象Eucryptorrhynchus brandti、赤拟谷盗Tribolium castaneum、绿豆象Callosobruchus chinensis、马铃薯甲虫Leptinotarsa decemlineata、甘薯象甲Cylas formicarius、毛健夜蛾Brithys crini、长壮蝎蝽Laccotrephes robustus等40种昆虫；但昆虫假死行为的发生机制仍未明确。随着技术的发展，从昆虫生理学（生物胺）、神经生物学甚至分子生物学角度研究昆虫假死行为机制成为可能。本文总结了近年来国内外关于昆虫假死行为的研究成果，重点介绍了昆虫假死行为发生机制方面的进展，指出了存在的问题和今后需要进一步研究的方向。

英文摘要:

The behavior of death-feigning is closely related to defense and survival strategy. Insects with death-feigning will shrink appendages and spontaneously enter a state of tonic immobility when stimulated by external physical stimuli or enemies. At present, the related research gradually increases, and the progress is great. We have a preliminary understandings of the characteristics, including duration, frequency, stimulation mode and other influencing factors. And the main research populations include Eucryptorrhynchus brandti, Tribolium castaneum, Callosobruchus chinensis, Leptinotarsa decemlineata, Cylas formicarius, Brithys crini, etc. Although the research on death-feigning has made great progress, there are still many problems to be solved, such as mechanism of death-feigning. Moreover, with the development of new technologies, we can provide new ideas for the study of death-feigning from the perspective of physiology (Biogenic amine), neurobiology and even molecular biology. This paper reviews the research progress of insect death-feigning behavior from the aspects of death-feigning characteristics, influencing factors and mechanism, and analyzing future research directions and trends, in order to provide reference for the study of death-feigning behavior.
