| 中文摘要: |
| 普通大蓟马 Megalurothrips usitatus 在海南省对豇豆造成严重危害且抗药性逐渐增强。本研究测定了 2019 年至 2021 年海南省普通大蓟马对氯菊酯和甲氰菊酯的抗性。结果表明, 海口、乐东和三亚 3 个地理种群对甲氰菊酯处于极高水平抗性, 对氯菊酯处于高水平抗性, 且抗性逐年增强。对普通大蓟马钠离子通道序列分析发现存在M283R突变, 该突变位于钠离子通道同源结构域Ⅰ。突变频率检测显示, 2019年至2021年连续3年海口种群该突变位点的突变频率分别为1/30、1/30、3/30, 有升高趋势。本研究发现海南省普通大蓟马从2019年到2021年对拟除虫菊酯类药剂的抗药性呈逐年上升趋势。 |

| Megalurothrips usitatus has caused serious damage to cowpeas in Hainan province and its resistance to insecticide is building up. This study investigated the resistance of M. usitatus to permethrin and fenpropathrin in Hainan province from 2019 to 2021. Haikou, Ledong and Sanya populations showed extremely high level of resistance to fenpropathrin and high level of resistance to permethrin, and the resistance enhanced year by year. The M283R mutation was found in the domain Ⅰ of the sodium channel in M. usitatus. The frequencies of this mutation was 1/30, 1/30 and 3/30 in three Haikou populations collected from 2019 to 2021, respectively, with an increasing trend. In a word, this study found that the resistance of M. usitatus to pyrethroids in Hainan province enhanced year by year from 2019 to 2021. |
