| 摘 要： | 采自甘肃兰州兴隆山公园的二斑叶螨(Tetranychus urticae Koch),用雌雄单系培养敏感品系(S),用螺螨酯处理二斑叶螨种群培养抗性品系(SP R)，用室内生测法对二斑叶螨S和SP R品系进行室内毒力测定。结果表明，二斑叶螨对螺螨酯抗性发展初期较慢，中期稳定，后期较快，选育至26代抗性指数(RI)达58.83。SP R对甲氰菊酯、氯氰菊酯有一定的交互抗性，RI分别为11.54和10.03；对苯丁锡、四螨嗪、苦皮藤生物碱、阿维菌素、氯氟氰菊酯、哒螨•四螨嗪、哒•水胺硫磷、三唑锡、三氯杀螨醇、哒螨灵、氧化乐果无交互抗性(1＜RI<5.00)；对浏阳霉素、毒死蜱、噻螨酮、柴油、哒螨灵、唑螨酯可能存在负交互抗性(RI<1)。

| Abstract: | The S strain of Tetranychus urticae Koch collected from Xinglong Mountain in Lanzhou of Gansu were reared by amphoterotoky.The SP-R strain was selected by spirodiclofen.Both strains were tested by slide dip bioassay method.The results showed that resistance development was slow at the beginning,stable at mid-term stage but fast at later period.After insecticide resistance was selected for 26 generations,the RI was 58.83.The SP-R had obvious cross resistance to fenpropathrin and cyhalothrin(resistance index,... |
