| 中文摘要: |
| 利用室内选育的抗阿维菌素小菜蛾品系和敏感品系分析了小菜蛾对阿维菌素的抗性遗传。结果表明,小菜蛾对阿维菌素的抗性为常染色体、不完全隐性遗传,而且可能是由多基因控制的抗性遗传。阿维菌素抗性品系对4 种杀虫剂的抗性谱测定结果表明,对马拉硫磷、溴氰菊酯、灭多威和农梦特无交互抗性。 |
| 英文摘要: |
| The inheritance mode of resistance to avermectins (AVMs) in diamondback moth (DBM), Plutella xylostella (L.) was evaluated from log dosage probit mortality curves constructed from the response of DBM larvae to AVMs treatment. The insects used for the study were taken from laboratory selected resistant and laboratory reared susceptible strains. The results of genetic analysis indicated that the resistance of DBM to AVMs was autosomal,incompletely recessive,and probably polygenic. The sensitivities of AVMs resistant strains to 4 insecticides had been tested. The results showed that it was no cross-resistance on the resistant strain to malathion, deltamethrin, methomyl and teflubenzuron. |
