| 中文摘要: |
| 昆虫是变温动物，温度对其生长发育、基本行为及进化途径都会产生很大的影响，种群的繁衍面临如何安全度过漫长而寒冷的冬季的挑战。通过长时间的进化，昆虫获得一系列完整的耐寒策略。绝大多数的昆虫都是耐寒昆虫，在陆地寒冷温度刺激下，昆虫受抗寒基因的调控，体内产生大量抗寒物质，如海藻糖、甘油、山梨醇、抗冻蛋白、热激蛋白等，提高昆虫的耐寒能力，使其得以在低温寒冷的条件下成功越冬。同样，经过冷驯化后的昆虫能显著提高昆虫的耐寒力。近年来，关于昆虫耐寒性、抗寒类蛋白的研究不断开展，研究内容涉及昆虫的耐寒性、抗寒基因HSPs和AFPs的调控、冷驯化诱导抗寒等方面。本文综述了昆虫耐寒性、主要耐寒策略及冷驯化诱发昆虫耐寒性增强等研究内容。有助于全面认识昆虫耐寒性及其作用机制，为天敌昆虫低温储存和提高生物防治等应用打下坚实的基础。 |
| 英文摘要: |
| Insects are poikilotherms which can be greatly infoluenced by temperature through disturbing growth and development, basic behavior and evolutionary pathway. Most insects are freeze-tolerant insects which can be regulated to produce mounts of cold-tolerant substances such as trehalose, glycerin, sorbitol, antifreeze proteins and heat-shock proteins to enhance the freeze resistance capability to overwinter when stimulated by the cold weather on land. Samely, the cold endurance revealed that insects can obviously strengthen cold-hardiness after cold-acclimation. Recent years research about insect cold endurance and cold-like proteins are carried out and the research contents involve insect cold endurance, regulation of cold-resist gene HSPs and AFPs and cold-acclimation. The paper concludes insect cold endurance, major cold-resistance policy and insect cold hardiness induced by cold acclimation. It contribute to a comprehensive understanding of its mechanism of insect resistance to cold to lay a solid foundation for natural enemy insect cold storage and raise insect biological control applications. |
