摘  要:
[目的]明确棉田天敌、蚜虫及室内龟纹瓢虫各虫态历期。[方法]调查棉田天敌、蚜虫发生情况,并观察室内龟纹瓢虫的各虫态历期。[结果]龟纹瓢虫6月在室内常温饲养历期为28.8 d。蚜虫盛期5 d后棉田出现龟纹瓢虫成幼虫盛期。生产实践中宜放宽棉蚜防治指标,以提高龟纹瓢虫的种群数量,控制棉铃虫等主要害虫。[结论]试验结果为龟纹瓢虫的化学防控提供了参考。

摘  要:
[Objective]The aim was to clear natural enemies,aphids in cotton field and indoor state of Propylaea japonica( Thunb.).[Method]We investigated the occurrence of natural enemies and aphids in cotton field,and observed the indoor state of Propylaea japonica( Thunb.).[Result]The indoor feeding state of Propylaea japonica( Thunb.) under normal temperature was 28. 8 days. There was a peak of Propylaea japonica( Thunb.) adults and larvae in cotton field after five days of aphids stage. So we should relax cotton aphid indexes,and improved the population quantity of Propylaea japonica( Thunb.) to control main insects.[Conclusion] The results provide reference for the chemical control of Propylaea japonica( Thunb.).
