摘　　要：为明确东亚小花蝽(Orius sauteri)对烟粉虱(Bemisia tabaci)若虫的捕食潜力,在室内条件下测定了东亚小花蝽5龄若虫和雌成虫对烟粉虱2~4龄若虫的喜好性和对烟粉虱4龄若虫的捕食能力以及东亚小花蝽密度对捕食烟粉虱的干扰作用。结果表明,东亚小花蝽对烟粉虱2龄和3龄若虫均表现为负喜好性,对烟粉虱4龄若虫表现为正喜好性。东亚小花蝽5龄若虫和雌成虫对烟粉虱4龄若虫的日捕食量分别为14.00和16.00头,瞬时攻击率分别为0.878和0.888,单头烟粉虱处理时间分别为0.047和0.034 d,东亚小花蝽雌成虫的捕食能力强于5龄若虫。东亚小花蝽的日捕食量与烟粉虱密度呈正相关,与搜寻效应呈负相关;随着东亚小花蝽密度的增加捕食作用率降低。To clarify the predation potential of Orius sauteri on the nymphs of Bemisia tabaci,the preference of the 5th instar nymphs and female adults of O.sauteri for the 2nd-4th instar nymphs of B.tabaci,the predation ability of O.sauteri on the 4th instar nymphs of B.tabaci,and the interference effect of different O.sauteri density on the predation of B.tabaci were investigated under indoor conditions.The results indicated that O.sauteri showed a negative preference for both the 2nd and 3rd instar nymphs of B.tabaci,while exhibiting a positive preference for the 4th instar nymphs of B.tabaci.The daily predation rates of the 5th instar nymphs and female adults of O.sauteri on the 4th instar nymphs of B.tabaci were 14.00 and 16.00,respectively,with instantaneous attack rates of 0.878 and 0.888,and handling time per B.tabaci of 0.047 and 0.034 days,respectively.The predatory ability of female O.sauteri adults was superior to that of the 5th instar nymphs.The daily predation rate of O.sauteri positively correlated with the density of B.tabaci but negatively correlated with its searching efficiency.The predation rate of O.sauteri decreased with the increase in its own density.
