摘　　要：研究了黄瓜钝绥螨雌成螨对不同虫态茶黄螨的功能反应.结果表明:黄瓜钝绥螨雌成螨对茶黄螨卵、幼螨、静止期螨和雌成螨的功能反应均符合Holling方程Ⅱ型,搜寻效率α与处理时间Th值各为0.1144,1.2433;0.4422,0.2243;0.2861,0.3577;0.4180,0.2676.黄瓜钝绥螨对茶黄螨各虫态均有很好的捕食能力,其中对幼螨的捕食能力最强.The functional response for female adults of the predatory mite, Amblyseius cucumeris, on various stages of Polyphagotarsonemus latus was determined. The results showed that all the functional responses for female adults of A. cucumeris on egg stage, larval stage, diapause stage, and adult stage of P. latus can be described by the Holling Ⅱ functional response type, and the attack rates α and the handling times Th  are 0.114 4,1.243 3;0.442 2,0.224 3;0.286 1,0.357 7;0.418 0, 0.267 6; respectively. Female adults of A. cucumeris have strong predatory ability to various stages of P. latus, especially to larval stage of P. latus.
