Abstract:

The effects of continuous use and rotational use of insecticides on the resistance developing and the carboxylesterase activity of Myzus persice(Sulzer) were studied by simulating used in field. The results showed that resistance of M. persice treated by nine continuous spraying to omethoate,meyhomyl and λcyhalothrin increased respectively by 54.2fold,8.9fold and 10.4fold,and the activity of α-NA carboxylesterase increased respectively by 20.0fold,24.0fold and 43.2fold,and the individuals with enzyme activity of 0.6 eased respectively by73%,87.6% and 43.8%. The resistance of M. persicae treated by three rotational spraying to omethoate,meyhomyl and λcyhalothrin increased respectively by 38.0fold,6.7fold and 5.0fold,and the enzyme activity increased by 10.2fold. The individuals with enzyme activity of 0.6 increased by 4.8% after treated by three rotations in order of omethoate,meyhomyl and λcyhalothrin. The resultsproved that rotational use of insecticides can delay the resistance developing,and decrease the carboxylesterase activity and the individuals with higher enzyme activity.
