| 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。

| Abstract: | 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 16L:8D. 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. |
