| 摘 要： | 以敏感品系为对照,利用室内筛选获得的虫酰肼和阿维菌素高抗品系Teb-R和Aba-R,测定了小菜蛾对几种新型杀虫剂的交互抗性。结果发现:小菜蛾对虫酰肼产生高水平抗性后(抗性倍数185.5倍),对阿维菌素表现出中等水平交互抗性(41.0倍),对茚虫威(11.4倍)和溴虫腈(5.3倍)仅表现出低水平交互抗性,对多杀菌素(1.7倍)和氯虫苯甲酰胺(1.4倍)则没有表现出明显的交互抗性。用阿维菌素筛选Teb-R品系39代后获得阿维菌素高抗品系Aba-R(593.8倍),该品系对茚虫威(12.3倍)表现出中等水平交互抗性,对多杀菌素(7.9倍)表现出低水平交互抗性,对溴虫腈(2.7倍)和氯虫苯甲酰胺(0.9倍)的交互抗性不明显;同时该品系对虫酰肼的抗性也由阿维菌素筛选前的185.5倍下降到筛选后的28.0倍,也没有交互抗性。基于上述研究结果认为,使用虫酰肼防治小菜蛾出现抗性后,可以使用多杀菌素和氯虫苯甲酰胺进行替代防治,但不宜用阿维菌素、茚虫威和溴虫腈进行替代防治;利用阿维菌素防治小菜蛾产生抗性后,可以用溴虫腈、氯虫苯甲酰胺和虫酰肼进行替代防治,但不宜用多杀菌素和茚虫威。

| Abstract: | With the susceptible strain as control,the resistance strains of Plutella xylostella to tebufenozide ( Teb-R) and to abamectin ( Aba-R) developed in laboratory were surveyed for their cross-resistance to several new insecticides. Toxicity bioassay showed that Teb-R strain ( resistance ratio,RR 185. 5) exhibited a moderate level of cross-resistance to abamectin ( RR 41. 0) , a low level of cross-resistance to indoxacarb ( RR 11. 4) and chlorfenapyr ( RR 5. 3) ,but no significant cross-resistance to spinosad ... |
