摘要
2019年,草地贪夜蛾入侵我国云南并定殖,2020年预计将北迁进入江淮,黄淮地区,防控形势严峻。草地贪夜蛾宿主广泛,喜欢凉爽湿润的气候和伴随着越冬地区温暖潮湿的天气,南方的冬天更有利于草地贪夜蛾生存和繁殖,使其能逃脱天敌的压制,这也预示着必须抓住窗口期,在爆发源头的南方地区加强防控力度,力保北方疫情最小化。鉴于目前中国无防治该虫的登记农药,我们根据农业农村部推荐的25种应急用农药,浙江省农业科学院植物保护和微生物研究所对26种杀虫剂对不同龄期草地贪夜蛾幼虫的室内毒力试验研究数据,进行做进一步用药分析,并提出草地贪夜蛾防治农药最佳制剂使用方案建议,供植保部门防治和新农药登记参考。
In 2019,Spodoptera frugiperda invaded and colonized Yunnan Province of China.In 2020,it is expected to move northward into Jianghuai and Huanghuai regions.The situation of prevention and control is grim.It has a wide range of hosts.It likes a cool and humid climate and warm and humid weather in the wintering area.The winter in the south is more conducive to its survival and reproduction,so that it can escape the suppression of natural enemies.This also indicates that we must seize the window period,strengthen the prevention and control efforts in the south of the outbreak source,and strive to minimize the epidemic situation in the north.In view of the fact that there is no registered pesticide to control the pest in China,we have made further drug analysis based on the laboratory toxicity test data of 26 kinds of pesticides to the larvae of Spodoptera pratensis in different ages by the Institute of plant protection and microbiology,Zhejiang Academy of Agricultural Sciences,according to the 25 kinds of emergency pesticides recommended by the Ministry of agriculture and rural areas,and put forward the best pesticide application scheme for the prevention and control of Spodoptera pratensis It is suggested to provide reference for prevention and control of plant protection departments and registration of new pesticides.
