| 中文摘要: |
| 采用浸叶法测定了来自5个地区的田间小菜蛾种群对8种杀虫剂的抗性水平。结果表明, 5个地区小菜蛾种群对氯虫苯甲酰胺均产生了中等水平以上的抗性, 江苏无锡和广东增城种群的抗性达1 428.16倍和6 642.12倍, 为极高抗性水平; 对丁醚脲均处于敏感或敏感性降低水平。5个地区的小菜蛾种群对甲氨基阿维菌素、虫螨腈、S-茚虫威、虫酰肼和唑虫酰胺等5种药剂的敏感性各异, 大多处于敏感或敏感性降低水平, 但也有些地区产生了中等水平的抗性。本研究结果明确了我国部分地区对小菜蛾抗药性情况, 可为小菜蛾的抗性治理提供参考。 |
| 英文摘要: |
| Resistance level of diamondback moth (Plutella xylostella) from five different regions to the eight insecticides were determined by leaf dipping method. The results showed that the resistance of the field diamondback moth populations in the five areas to chlorantraniliprole were above the medium level, and the resistance of the population in Wuxi and Zengcheng was 1 428.16 fold and 6 642.12 fold, respectively, which were at extremely high resistance level. The field diamondback moth population in five areas was sensitive to diafenthiuron. The sensitivities of field diamondback moth populations in five regions to emamectin benzoate, chlorfenapyr, S-indoxacarb, tebufenozide and tolfenpyrad, were different, and most of them were at sensitive or sensitive-decreased level, but some populations showed medium resistance level. These results specified the resistance level of diamondback moth in part areas of China, which could provide a scientific basis for resistance management of diamondback moth in future. |
