【摘要】 以苹果蠹蛾和梨小食心虫为研究对象,研究了不同复合式信息素迷向剂处理(600、900、1 200个·hm^-2)对苹果蠹蛾和梨小食心虫的防控效果,以期为合理应用性信息素迷向剂防治虫害提供参考依据。结果表明:复合式性信息素迷向剂胶处理与对照相比迷向干扰效果显著。7月20日和9月10日的蛀果率调查结果显示,上述3个使用密度处理区苹果蛀果率分别比对照低72.46%、90.58%、90.58%和79.79%、93.09%、93.09%,随时间延续防效略有提高,复合式性信息素迷向剂有良好的缓释效果,持效期可达5个月。更多还原

【Abstract】 Codling moth(Cydia pomonella) and oriental fruit moth(Grapholitha molesta) were taken as materials.In order to provide a theoretical basis for the rational application of pheromone digitizer for pest control,a field experiment in apple orchard was conducted to evaluate the actual control effects of disrupting the mating of codling moth(Cydia pomonella) and oriental fruit moth(Grapholitha molesta) with a dual sex pheromone dosage(600,900,1 200 per 1 hm~2).The results showed that dual sex pheromone agents were more obvious than the control,the damaged fruit rates were reduced by 72.46%,90.58%,90.58% on July 20 th and 79.79%,93.09%,93.09% on September 10 th than that of the control,respectively.The results demonstrated that the good control effect of disrupting mating with a dual sex pheromone dosage to codling moth and oriental fruit moth,and the sustained released duration of control in apple orchards was over 5 months.更多还原
