为明确溴氰虫酰胺对西瓜烟粉虱的防治效果，以吡虫啉为对照，通过田间试验比较了溴氰虫酰胺36 g/hm2、54 g/hm2、72 g/hm2及90 g/hm2及吡虫啉90 g/hm2（剂量为有效成分）对西瓜烟粉虱成虫和若虫的控制效果及对作物长势的影响。试验结果表明，在西瓜烟粉虱成虫发生初期施用溴氰虫酰胺悬浮剂54 g/hm2及以上剂量，7 d 间隔，连续施药2次，末次药后7 d对烟粉虱成虫和若虫的防效均高于80%，明显优于吡虫啉处理，同时能够增加西瓜茎蔓长度、增强西瓜长势，降低烟粉虱对西瓜的为害。

In order to determine the control efficacy of cyantraniliprole against watermelon white fly, we compared the control efficacy of cyantraniliprole and imidacloprid with different concentrations against watermelon white fly. The results showed that, while were applied twice every seven days, the control efficiencies of cyantraniliprole were higher than 80%against the white fly adults and nymphs with active ingredient higher than 54 g/hm2 seven days after the second spraying. In conclusion, cyanthraniliprole showed good control efficacy against watermelon white fly than imidaclorid, and cyantraniliprole could make the vine length increased, growth vigor strengthened and pests damage reduced.
