摘　　要：采用稻茎浸渍法测定了烯啶虫胺对广州市本地稻飞虱(褐飞虱和白背飞虱)3龄若虫的毒力,结果表明:烯啶虫胺对褐飞虱和白背飞虱的LC50值分别为0.613 mg/L和0.891 mg/L。2010年和2011年田间试验结果表明:10%烯啶虫胺水剂对稻飞虱具有较好的防治效果,当用药量为45g/hm2时,药后3 d防治效果分别为84.28%和82.50%,药后7 d的防治效果分别为86.80%和87.60%。Toxicities of nitenpyram against the 3rd instar nymphs of Nilaparvata lugens St？l and Sogatella furcifera Horváth, which were collected from Guangzhou local district, were evaluated by the rice stem-dipping method. The results showed that the LC 50 values of nitenpyram to Nilaparvata lugens St？l and Sogatella furcifera Horváth were 0.613 mg/L and 0.891 mg/L, respectively. Field effect trials were carried out in 2010 and 2011. The results showed that nitenpyram 10%AS at 45 g/hm2 had better control effects on Nilaparvata lugens St？l and Sogatella furcifera Horváth. The efficacies were 84.28%and 82.50%on the 3rd day after spraying, and the efficacies were 86.80%and 87.60%on the 7th day after spraying in 2010 and 2011, respectively.
