Abstract: 【Objective】 This project aims to systematically determinecomprehensively evaluates the resistance level of the main population ofLisorhoptrus 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.
