中文摘要：

植绥螨被广泛应用于控制多种农作物上的螨类和其它害虫,是一类很有利用价值的天敌资源。种群性比及性别决定机制是植绥螨生殖生理研究上的一个重要领域,与生物的遗传、个体发育、进化等密切相关。本文对植绥螨的性别决定机制、影响植绥螨性比的因素以及性比调控在捕食螨规模化生产及实践应用中的意义进行了分析。

英文摘要：

Phytoseiid mites can be used to control mites and insects in various crops and are one of very important natural enemy resources.Population sex ratios and sex determination,which closely related to heredity,ontogenesis and evolution,are very important fields in studying reproductive physiology of phytoseiid mites.In this article,the sex determination mechanism,some factors affecting sex ratio,the meanings of sex ratio adjusted artificially in mass rearing and application of phytoseiid mites were reviewed and analyzed.
