利用捕食性天敌防治棉叶螨是综合防治技术中不可缺少的环节。笔者对北疆部分棉田中的叶螨天敌作了调查和采集 ,从 10 0多号标本中初步鉴定出棉叶螨天敌 32种 ,其中天敌昆虫18种 ,蜘蛛 4种 ,捕食螨 10种 ,并对其分布和形态分别作了记述 ,还发现在棉田中出现早、数量多、捕食明显的种类有食螨蓟马、食螨瘿蚊、草蛉、小花蝽、食螨瓢虫、蜘蛛和多种捕食螨 ,可为生产者和研究者对棉叶螨的生物防治提供依据。
The use of predatory natural enemies to control cotton spider mite is an integral part of integrated control technology. The authors investigated and collected spider mite natural enemies in some cotton fields in north Xinjiang. 32 species of natural enemies of cotton spiders were identified from more than 10 0 specimens, including 18 species of natural enemies, 4 species of spiders and 10 species of predatory mites The distribution and morphology of the two species were described separately. In the cotton field, the early occurrence and the number of predatory species were observed. The predatory species were Tetranychus urticae, Tetranychus urticae, Gracilaria spp., Tetranychus urticae, Species of predatory mites, for producers and researchers provide a basis for the biological control of cotton spider mites.
