小菜蛾抗药性的产生,导致小菜蛾发生为害逐年加重。为了准确掌握小菜蛾抗药性的发展动态,及时提出抗性害虫的综合治理措施,指导科学用药和发展农药新品种,从1999年开始,在深圳等6个地区对小菜蛾进行了室内毒力测定,对其抗性进行监测,并根据抗药性监测结果,提出综合治理措施,建立抗药性综合治理示范区,有效地控制了蔬菜小菜蛾的发生为害。
Plutella xylostella resistance, lead to the occurrence of the diamondback moth increased year by year. In order to accurately grasp the development trend of drug resistance of Plutella xylostella, put forward the comprehensive control measures of resistant pests in time, guide the scientific use of medicines and develop new varieties of pesticides. Since 1999, the virulence of Plutella xylostella was determined in six areas including Shenzhen To monitor their resistance. Based on the results of drug resistance monitoring, comprehensive treatment measures were put forward to establish a demonstration area for comprehensive drug resistance management, which effectively controlled the occurrence of vegetable diamondback moth.
