摘  要：
[目的]双尾新小绥螨是一种新疆本地的捕食螨,研究其对土耳其斯坦叶螨三种螨态(卵、幼螨及若螨)捕食偏好性和田间控害效果.[方法]采用室内试验及田间不同益害比释放双尾新小绥螨,评价该捕食螨对新疆棉田土耳其斯坦叶螨的控制效果.[结果]双尾新小绥螨对土耳其斯坦叶螨三种螨态取食具有选择性,土耳其斯坦叶螨的幼若螨是双尾新小绥螨偏好虫态.在田间释放双尾新小绥螨,可有效抑制土耳其斯坦叶螨的卵、幼虫、若虫以及整个种群数量增长;不同益害比释放捕食螨时,1∶5和1∶10的控效较好,1∶20释放捕食螨效果较差.[结论]双尾新小绥螨可作为一种优良新疆本地天敌,应用双尾新小绥螨在棉田对土耳其斯坦叶螨进行生物防治时,推荐最佳释放比例1∶10.

摘  要：
【Objective】 The purpose of this paper is to determine the predation preference and the field control effect of Neoseiulus bicaudus Wainstein, a kind of native predatory mite in Xinjiang, on three mite states(egg, larva, nymph) of Tetranychus turkestani.【Method】 The control effect of the natural enemy on Tetranychus turkestani in cotton fields of Xinjiang was evaluated by indoor experiments and the release of Neoseiulus bicaudus Wainstein with different benefit-harm ratios in fields.【Result】 The predatory mites had the selective feeding to the three mite states of Tetranychus turkestani. The larva and nymph are the preferred insect states of the predatory mites. In the field, the release of the predatory mites could effectively inhibit the growth of the eggs, larvae, nymphs and the whole population of the harmful mites. The control effect of 1∶5 and 1∶10 was better than that of 1∶20 when different benefit-harm ratios were released.【Conclusion】 Neoseiulus bicaudus can be regarded as an excellent natural enemy in Xinjiang, and the best release ratio was recommended 1∶10 for biological control of Tetranychus turkestani in cotton fields.
