摘　　要：为明确胡瓜新小绥螨Neoseiulus cucumeris Oudermans对烟粉虱Bemisia tabaci Gennadius的控害潜能,在(26±1)℃、相对湿度65%±5%、光周期16L:8D条件下,研究了各螨态胡瓜新小绥螨对不同发育阶段烟粉虱的捕食作用。结果表明,胡瓜新小绥螨幼螨期较短,不取食烟粉虱,其他不同螨态的胡瓜新小绥螨可捕食除4龄若虫和成虫以外的其他各虫态的烟粉虱,捕食功能反应符合HollingⅡ型;胡瓜新小绥螨雌成螨对烟粉虱卵的日捕食量最大(8.5粒/雌),对烟粉虱3龄若虫的日捕食量最小(2.1头/雌);雌成螨对烟粉虱卵具有较高的瞬间攻击率(0.038)和寻找效应(0.025)。研究表明,胡瓜新小绥螨对烟粉虱卵及低龄若虫的捕食能力较强,是烟粉虱发生初期的有效天敌。To assess the control potential of a predator mite(Neoseiulus cucumeris Oudermans)on the invasive whitefly,Bemisia tabaci Gennadius MEAM1,the functional responses of different stages of N.cucumeris to the whitefly were investigated at laboratory conditions of(26±1)℃,RH 65%±5%and photoperiod of 16 L:8 D.The results showed that,with exception of a short-lived non-feeding nymphal stage,the nymphs and adults of N.cucumeris could predate on most stages of B.tabaci except the forth-instar nymphs and adults.The functional response of N.cucumeris to prey on B.tabaci corresponded to a Type II Holling curve.The daily predated prey number of N.cucumeris female adults was the highest for host eggs(8.5 eggs/female/day)and the lowest for host third-instar nymphs(2.1 nymphs/female/day).The instantaneous attacking rate and searching efficiency of N.cucumeri female adults on B.tabaic eggs was 0.038 and 0.025,respectively.These results indicate that N.cucumeris has a high predatory potential on eggs and young nymphs of B.tabaci,and can be used in biological control of B.tabaci at the early occurring period.
