摘要
本文在测定发现新疆特克斯县马铃薯甲虫Leptinotarsa decemlineata(Say)田间种群对测定杀虫剂敏感的基础上,采用特克斯田间种群确定了19种常用农药品种的诊断剂量,监测了新疆奇台(QT)、阜康(FK)、乌鲁木齐(URMQ)、昌吉(CJ)、乌苏(US)、特克斯(TKS)、尼勒克(NLK)、察布查尔(QPQL)、新源(XY)和阿勒泰(ALT)共10个县市马铃薯甲虫对常用药剂的抗性水平。发现采自昌吉和新源的马铃薯甲虫种群对三氟氯氰菊酯分别为34.3%和65.7%;采自乌苏的马铃薯甲虫种群对高效氯氰菊酯的存活率为25.0%;采自奇台和尼勒克的马铃薯甲虫种群对马拉硫磷存活率分别为60.1%和29.0%;采自昌吉和尼勒克的马铃薯甲虫种群对丁硫克百威存活率分别为64.3%和99.0%;采自昌吉的马铃薯甲虫种群对吡虫啉存活率为50.3%。上述结果证明马铃薯甲虫在新疆局部地区已对常用农药出现明显抗性。
The proportion of individuals of Leptinotarsa decemlineata （Say） resistant to several commonly used synthetic insecticides was determined in populations from 10 locations in Xinjiang; Qitai （QT）,Fukang （FK）, Urumqi （URMQ）,Changji （ CJ）,Usu （ US）,Tekes （ TKS）,Nilka （ NLK）,Qapqal （ QPQL）,Xinyuan （XY） and Altay （ALT）. 34. 3% and 65. 7% of the CJ and XY populations were resistant to cyhalothrin,and 25. 0% of the US population resistant to α-cypermethrin. Similarly,60. 1% and 29. 0% of the QT and NLK populations showed resistance to malathion,64. 3% and 99. 0% of the CJ and NLK populations were resistant to carbofan,and 50. 3% of the CJ populations were resistant to imidacloprid. These results demonstrate that some populations of L. decemlineata in the Xinjiang Uygur autonomous region have developed detectable levels of resistance to conventional insecticides.
