Abstract: Insecticide resistance in different populations of the white backed planthopper, Sogatella furcifera collected from Zhejiang, Guangxi, Yunnan and Hainan provinces in China was measured. The resistant levels to methamidophos, malathion, isoprocarb and buprofezin were slightly higher in Yunnan and Hainan populations, but the difference was not significant. The development of insecticide resistance in Sogatella furcifera was discussed.

Key words: Sogatella furcifera, insecticide, resistance, population

摘要： 对采集自浙江、广西、云南和海南省的4个白背飞虱种群的抗药性进行了评价。对甲胺磷、马拉硫磷、叶蝉散和扑虱灵4种药剂的抗性，以云南和海南两种群较高，但差异未达显著水平。就白背飞虱抗药性的发展趋势进行了讨论。
