性诱剂在斜纹夜蛾监测预报中的应用

The Application of Sex Attractant on Monitoring and Forecasting of Spodoptera litura

[目的]提高斜纹夜蛾监测预报的准确性,探索性诱剂在斜纹夜蛾的监测预报应用效果。[方法]通过性诱集斜纹夜蛾成虫,结合系统调查斜纹夜蛾田间发生动态,探索性诱剂在斜纹夜蛾监测、预报中的应用。[结果]掌握了武汉蔡甸地区全年斜纹夜蛾田间发生动态、发生世代、主害代及时段,较好地实现了性诱剂在斜纹夜蛾监测预报中的应用。[结论]性诱剂为斜纹夜蛾的准确测报和科学指导防治提供了新途径。

[Objective] In order to improve the accuracy monitoring and prediction of spodoptera litura, and explore application effect of sex attractant on monitoring and forecasting of spodoptera litura. [ Method] The application of monitoring and prediction of sex attractant in Spo- doptera litura was explored combined with investigating field conditions of spodoptera litura by trapping Prodenia litura adults. [ Result] The annual field conditions, generations, major pestilent generation and periods of spodoptera litura in Cadian of Wuhan were mastered. The appli- cation of monitoring and prediction of sex attractant in Spodoptera litura was realized. [ Conclusion] The sex attractant provided a new way for accurately forecast and scientific guidance of Spodoptera litura.
