摘要:

【目的】明确沃氏新小绥螨对入侵害螨伊氏叶螨的生物防治潜力。【方法】在实验室条件下，测定沃氏新小绥螨在番茄和龙葵2种常见茄科植物上对伊氏叶螨3种螨态(卵、幼螨、若螨)的捕食效能和自身密度干扰效应。【结果】沃氏新小绥螨在番茄和龙葵上对伊氏叶螨的捕食功能反应均属于Holling Ⅱ型，且偏好取食伊氏叶螨卵和若螨；在龙葵上对伊氏叶螨的处理时间均短于在番茄上对相同螨态的处理时间，且对若螨的处理时间最短，为0.02 d；在龙葵上对伊氏叶螨幼螨的捕食能力最大，为42.34。沃氏新小绥螨对伊氏叶螨幼螨的搜索效应最大，在猎物密度固定的情况下，捕食率随自身密度升高而下降。【结论】沃氏新小绥螨对伊氏叶螨具有良好的控害能力。

Abstract:

【Aim】 This study aims to assess the predatory capacity of Neoseiulus womersleyi onTetranychus evansi. 【Method】 The functional response, searching efficiency, and self-density interference effect of N. womersleyi on T. evansi were investigated via two Solanaceae host plants,Solanum lycopersicum andS. nigrum. 【Result】N. womersleyi showed Holling type Ⅱ functional responses to the eggs, larvae, and nymphs of T. evansi on bothS. lycopersicum andS. nigrum.N. womersleyi exhibited a preference for the eggs and nymphs of T. evansi. The handling time of N. womersleyi for T. evansi at the three stages onS. nigrum was shorter than that on S. lycopersicum, with the shortest handling time being 0.02 day for the nymphs on S. nigrum.N. womersleyi demonstrated the highest predation capacity for the larvae feeding onS. nigrum, with a predation rate reaching 42.34. The searching efficiency of N. womersleyi was greater for larvae than for eggs and nymphs. Under fixed prey density conditions, the predation rate of N. womersleyi decreased as its own density increased. 【Conclusion】N. womersleyi possesses strong control potential againstT. evansi on bothS. lycopersicum andS. nigrum.
