摘　　要：卵滞育是家蚕应对周期性不利自然环境表现出的一种在胚胎形成早期发育停滞的生理现象。为满足蚕业生产需要,通常使用产后盐酸浸渍方法以快速解除滞育。由于使用盐酸存在一定的安全隐患,研究更加安全环保的新方法具有重要意义。此外,家蚕既是重要的经济昆虫,也是鳞翅目模式生物,研究其滞育解除的生理变化与分子调控机制,有望育成非滞育系家蚕新品种。本文综述分析了各种人工解除滞育方法的优势和缺陷,并总结了滞育解除的生理生化及分子机制,以期为研究人工解除蚕卵滞育提供参考。Egg diapause in the silkworm is a physiological process of embryonic development stagnation exhibited by silkworm eggs in a cyclically unfavorable environment.To meet the needs of sericultural production,postnatal hydrochlo-ric acid impregnation is often used to artificially release diapause quickly.Since the use of hydrochloric acid has certain safety risks,it is important to study new methods that are safer and more environmentally friendly.In addition,the silk-worm is not only an important economic insect,but also a model organism of Lepidoptera.The study of the physiological changes and molecular regulatory mechanisms of its diapause release is expected to breed new varieties of silkworm producing non-diapause eggs.This paper reviews and analyzes the advantages and drawbacks of various methods for the artificial release of diapause,and summarizes the physiological,biochemical and molecular mechanisms of diapause release,in order to provide a reference for the research on the artificial release of diapause of silkworm eggs.
