摘要
为明确我国田间烟粉虱的抗性水平,2019年采用指形管法测定了5种杀虫剂对6个地区田间烟粉虱样品的毒力情况。结果表明:所有烟粉虱种群均对吡虫啉、噻虫嗪表现出较高抗药性,其中湖南长沙种群对吡虫啉的抗性倍数高达113.14倍;所有烟粉虱种群对氟吡呋喃酮、阿维菌素和溴氰虫酰胺均处于敏感水平。结合文献报道和调查结果,田间烟粉虱种群已经对吡虫啉、噻虫嗪表现出较高的抗药性,建议谨慎使用;推荐继续使用氟吡呋喃酮、阿维菌素、溴氰虫酰胺田间防治烟粉虱。
To clear and definite the resistance level of Bemisia tabaci(Gennadius)in fields,this study adopted finger-shape tube method in 2019 at 6 areas to determine the virulence of 5 insecticides of B.tabaci samples.The results showed that all B.tabaci in the 6 regions has higher resistance to imidacloprid and thiamethoxam.The highest resistance level of B.tabaci population to imidacloprid was 113.14 in Changsha,Hunan.All B.tabaci populations were sensitive to flupyradifurone,avermectin and cyantraniliprole in the 6 regions.Based on previous literature reports and findings of this investigation,B.tabaci populations had shown higher resistance to imidacloprid and thiamethoxam.Careful usage was suggested.Continuously using flupyradifurone,avermectin,and cyantraniliprole in fields to control B.tabaci was recommended.
