摘要
【目的】研究主要稻区稻水象甲Lissorhoptrus oryzophilus田间种群对目前常用杀虫剂的抗性水平,为防治该虫科学用药提供依据。【方法】以南疆阿克苏稻区温宿县种群(WS)为敏感基线,采用室内点滴法,测定察布查尔(Qapqal)和五家渠(WJQ) 2个主要稻区稻水象甲田间种群对6种杀虫剂的抗性水平。【结果】以南疆主要稻区温宿县稻水象甲地理种群为敏感种群,察布查尔(Qapqal)和五家渠2个地理种群(WJQ)对6种供试药剂的敏感性均有不同程度的下降,其中,对95.87%噻虫嗪、97%毒死蜱、97%吡虫啉、95.1%高效氯氰菊酯和98%溴氰菊酯等多数药剂仍处于敏感状态(抗性倍数<5),对96%氯虫苯甲酰胺的抗性倍数均高于5.92,属于已产生低水平抗性。【结论】在水稻生长季节应避免重复使用或限用96%氯虫苯甲酰胺,注意与其它药剂混用、轮用,延缓该地区稻水象甲抗药性发生。
【Objective】This project aims to systematically determinecomprehensively evaluates the resistance level of the main population of Lisorhoptrus oryzophilus to commonly used insecticides in Xinjiang,which is the current commonly used insecticides,and aims to providein the hope of providing a basis forscientific basis for the control scientific use of the insects.【Method】Taking the Wensu County population(WS)in the Aksu rice region of southern Xinjiang as the sensitive baseline,the indoor main drop method was used to determine the resistance level of the 2 two main rice varieties in Qapqal in Ili River Valley and the Wujia Canal(WJQ)in the Urumqi Rice Regionto 6 insecticides in two major rice regions:Qapqal in Ili River Valley and the Wujia Canal(WJQ)in the Urumqi.The level of resistance of six species of insecticides to the field population of rice water weevil.【Result】The two geographic populations of Qapqal and Wujiaqu(WJQ)currently had different degrees of sensitivity to the six tested agents,of which 95.87%thiamethoxam,97%chlorpyrifos,97%imidacloprid,95.1%beta-cypermethrin and 98%deltamethrin were still sensitive(resistance multiple<5),but the resistance multiple to 96%chlorantraniliprole was higher than 5.92,which belonged to a low level of resistance.【Conclusion】Therefore,it is suggested that the repeated use of 96%chlorobenzamide should be avoided or restriction of it should be encouraged in the rice growing season and the mixture and rotation with other insecticides should be paid attention to in order to delay the occurrence of resistance of rice water weevil in this area.
