天敌的增殖是农林害虫生物防治的主要措施之一,室内大量繁殖寄生性和捕食性天敌为提供天敌的周期性释放,作为补充天敌的本地自然种群或引进天敌的种群来直接防治或间歇控制害虫种群在可允许水平之下。本文介绍了正在我国推广应用或研究成功的几种赤眼蜂、平腹小蜂、红铃虫金小蜂、黑胸茧蜂,紫腹白虫小茧蜂、烟蚜茧蜂、几种草蛉、孟氏隐唇瓢虫、七星瓢虫、异色瓢虫、刺兵蝽、土耳其扁谷盗及几种钝绥螨的大最繁殖方法和它们的应用。
Proliferation of natural enemies is one of the main measures for the biological control of agroforestry. Indoor mass propagation of parasitic and predatory natural enemies provides immediate control or intermittent control of pests by providing periodic release of natural enemies, as natural indigenous populations that supplement natural enemies, or by introducing populations of natural enemies The population is below the allowable level. This article introduces several kinds of Trichogramma, Apathew beetle, Apis mellifera beetle, Crayfish beetle, Apodemus agrariformis, Aphidius brachygnathus, several species of grass that are being popularized or researched in our country.蛉, Ladybug, Papilio buteo, Coccinella septempunctata, Chameleon ladybug, Buzzard bugs, Turkey otter bugs and several species of Amblyseius and their applications.
