性诱剂防治二化螟效果的研究

在黑龙江省尚志市和方正县对应用二化螟性诱剂诱杀雄性二化螟成虫进行了试验。结果表明：二化螟性诱芯田间诱杀持续期为31-36 d,每晚最大诱蛾量分别为1120头和590头。性诱剂诱杀区枯心苗率、虫株率和白穗率与对照区相比差异显著。性诱剂诱杀区和常规施药防治区增产率分别为20.7%和19.2%,投入产出比分别为1∶22和1∶13。研究表明：性诱剂诱杀效果较好,与化学农药防治效果相当。应用二化螟性诱剂来防治二化螟,达到了节本、简便、增产、增效、增收的目的,是一项可以大力推广的绿色植保技术。

Study on Efficacy of Sex Attractant on Chilo suppressalis

Experiment of the effect of sex attractant on rice stem borer was conducted in Shangzhi and Fangzheng of Heilongjiang province.The result showed that the longevity was 31～36 d and the maximum catches in single night were 1 129 and 590,respectively.The rate of dead tiller,white head and attacting rate in test areas comparing with control were significant difference.The production increasing rate of sex attractant test area and normal pesticide application was 20.7% and 19.2%,and input-output ratio was 1:22 and 1:13,respectively.The research showed that the effect of sex attractant was better,and equivalent with chemical pesticide.Application of Chilo suppressalis sex attractant against Chilo suppressalis met the requirement of cost saving,simple and convenient,increasing,synergism,income increase,which was a extensive popularization,green plant protection technology.
