采用稻茎浸渍法测定了2013年和2014年采自贵州省贵阳、平坝、遵义、黔西、平塘及玉屏6地白背飞虱种群对8种杀虫剂的敏感性。测定结果表明,白背飞虱对噻虫嗪的敏感性最高,LC50值为0.060~0.93 mg/L(平均0.33 mg/L)；其次为吡虫啉、毒死蜱、环氧虫啶和噻嗪酮,其 LC50值分别为0.080~2.84 mg/L(平均1.03 mg/L)、1.09~3.89 mg/L (平均2.27 mg/L )、0.59~10.07 mg/L (平均2.71 mg/L )和0.28~18.15 mg/L (平均4.96 mg/L)；白背飞虱对敌敌畏、吡蚜酮和异丙威的敏感性相对较低,LC50值为0.89~57.96 mg/L,LC50平均值分别为10.03、12.16和22.44 mg/L。两年抗药性检测结果表明,贵州省6地白背飞虱种群对吡蚜酮、噻嗪酮和吡虫啉表现出低至中等水平的抗性,而对其余5种药剂仍较敏感。
採用稻莖浸漬法測定瞭2013年和2014年採自貴州省貴暘、平壩、遵義、黔西、平塘及玉屏6地白揹飛虱種群對8種殺蟲劑的敏感性。測定結果錶明,白揹飛虱對噻蟲嗪的敏感性最高,LC50值為0.060~0.93 mg/L(平均0.33 mg/L)；其次為吡蟲啉、毒死蜱、環氧蟲啶和噻嗪酮,其 LC50值分彆為0.080~2.84 mg/L(平均1.03 mg/L)、1.09~3.89 mg/L (平均2.27 mg/L )、0.59~10.07 mg/L (平均2.71 mg/L )和0.28~18.15 mg/L (平均4.96 mg/L)；白揹飛虱對敵敵畏、吡蚜酮和異丙威的敏感性相對較低,LC50值為0.89~57.96 mg/L,LC50平均值分彆為10.03、12.16和22.44 mg/L。兩年抗藥性檢測結果錶明,貴州省6地白揹飛虱種群對吡蚜酮、噻嗪酮和吡蟲啉錶現齣低至中等水平的抗性,而對其餘5種藥劑仍較敏感。

Rice stem-dipping method was used for determining the susceptibilities of white-backed planthopper to 8 insecticides,which collected from Guiyang,Pingba,Zunyi,Qianxi,Pingtang and Yuping rice production districts of Guizhou Province in 2013 and 2014.Results presented that different populations of Sogatella furcifera had the highest susceptibility to thiamethoxam,with LC50 value ranged from 0.060 to 0.93 mg/L and mean value of 0.33 mg/L.Followed by imidacloprid,chlorpyrifos,cycloxaprid and buprofezin,with LC50 values ranged from 0.080 to 2.84 mg/L,1.09 to 3.89 mg/L,0.59 to 10.07 mg/L and 0.28 to 18.1 5 mg/L,respectively,and with mean values of 1.03,2.27,2.71 mg/L and 4.96 mg/L,respectively.All S .furcifera populations showed much poor sensitivity to dichlorvos,pymetrozine and isoprocarb,with LC50 values ranged from 0.89 to 57.96 mg/L, and with mean LC50 values of 10.03,12.1 6 and 22.44 mg/L,respectively.All six S .furcifera populations showed different sensitivities to the same insecticide.Resistance detection of six S .furcifera populations in Guizhou Prov-ince showed that the resistance levels of pymetrozine,buprofezin and imidacloprid were low to middle,while oth-er five insecticides were all sensitive to S .furcifera .
