今年,我们省农林局、科技局、省农科院和上海昆虫研究所成立了黑尾叶蝉抗药性协作小组。选取了用药时间较短、用药水平较低的庆元、龙泉等地区作为相对敏感地区,而以用药时间长,用药水平高的嘉兴、平原区作为抗性区,也选取一些用药水平一般的地区,作为进行黑尾叶蝉对马拉松、乐果等常用农药以及新杀虫剂的敏感度的测定。一年来,通过测定和试验取得了一定成果:(1) 初步摸清了浙江地区黑尾叶蝉对滴滴涕、1605、马拉松和乐果等杀虫剂的抗药性
This year, our Provincial Bureau of Agriculture and Forestry, Science and Technology Bureau, Provincial Academy of Agricultural Sciences and Shanghai Institute of Entomology set up a black-leafhopper resistance collaborative team. Select Qingyuan, Longquan and other areas with relatively short medication time and relatively low drug levels as relatively sensitive areas. In Jiaxing-Pingyuan District, which takes a long time and has a high level of drug treatment as the resistance area, some areas with normal drug levels were also selected , As a measure of the susceptibility of Nephotettix cincticeps to commonly used pesticides such as marathon and dimethoate and to new insecticides. In the past year, some achievements have been made through the measurement and experiment: (1) The resistance of the black-tailed rice leafhopper to DDT, 1605, marathon and dimethoate insecticides in Zhejiang Province has been initially found out
