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.
