Method for breeding predatory mites on large scale by using frozen preys

The invention relates to a method for feeding predatory mites through frozen preys. Wherein predatory mite preys (such as carpoglyphus lactis) are frozen at-20 to-40 DEG C, and the predatory mites are fed by the frozen preys. The predatory mites (such as amblyseius orientalis) are bred on a large scale by adopting frozen preys (such as carpoglyphus lactis) through research, the storage period of the preys (such as carpoglyphus lactis) is prolonged, the feed state is better, and the predatory mites (such as amblyseius orientalis) can be stably and massively bred. Compared with a conventional feeding method, the method has obvious technical benefits and economic benefits. 本发明涉及一种冷冻猎物饲养捕食螨的方法。其中是将捕食螨猎物（如甜果螨）在-20至-40℃下冷冻，将冷冻过的猎物饲养捕食螨。本发明通过研究采用冷冻猎物（如甜果螨）进行规模化饲养捕食螨（如东方钝绥螨），延长猎物（如甜果螨）的贮存期和更佳饲料状态，能够稳定地大量饲养捕食螨（如东方钝绥螨）。本发明的方法相对于常规饲养方法来说，具有明显的技术效益和经济效益。
