对多种杀虫剂的抗药性已成为控制烟粉虱的最大挑战。为了解决这一问题，最近引入了四种具有新作用模式的杀虫剂（环虫酰胺、氰虫酰胺、氟啶虫胺和氟吡呋酮）来控制B。烟粉虱在本研究中，我们收集了18个B。2018 - 2019年中国烟粉虱种群对上述4种杀虫剂和2种代表性传统杀虫剂（联苯菊酯和吡虫啉）的抗性水平。结果表明，环虫酰胺对B的毒力最强，LC_（50）为3.4 ~ 21.2 mg/L。烟粉虱田间种群对环虫酰胺的敏感性基线为13.5 mg/L的平均LC 50。另外三种新引进的杀虫剂（氰虫苯甲酰胺、氟啶虫胺和氟吡呋酮）对田间种群也表现出较高的毒性，而两种传统杀虫剂的LC 50值较低，联苯菊酯和吡虫啉的LC 50值分别为16.9 ~ 296.6mg/L和33.1 ~ 397.0mg/L。这些结果表明，新引进的杀虫剂目前可以被认为是有效的替代杀虫剂在昆虫抗性管理计划的B。中国的烟粉虱
Resistance to multiple insecticides has become the biggest challenge to controlling Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae). In attempts to remedy the problem, four insecticides with novel modes of action (cyclaniliprole, cyantraniliprole, sulfoxaflor, and flupyradifurone) have recently been introduced to control B. tabaci. In the present study, we collected 18 B. tabaci populations in China from 2018 to 2019 to determine their resistance levels to six insecticides including the above four insecticides and two representative traditional insecticides (bifenthrin and imidacloprid). The results showed cyclaniliprole with LC50 values ranging from 3.4 to 21.2 mg/L was the most toxic insecticide to B. tabaci field populations and their average LC50 of 13.5 mg/L was used for the susceptible baseline to cyclaniliprole. The other three newly introduced insecticides (cyantraniliprole, sulfoxaflor, and flupyradifurone) also exhibited high toxicity to the field populations, however, the two traditional insecticides tested were of low toxicity with LC50 values ranging from 16.9 to 296.6 mg/L and from 33.1 to 397.0 mg/L for bifenthrin and imidacloprid, respectively. These results demonstrate that the newly introduced insecticides can currently be considered as effective alternative insecticides in insect resistance management programs for B. tabaci in China.
