甜菜夜蛾性信息素的研究与应用

甜菜夜蛾Spodoptera exigua(Hbner)已成为我国的重要农业害虫,其高抗药性和危害具有隐蔽性,致使防治十分困难。文章介绍甜菜夜蛾性信息素的主要成分、活性、配比、诱芯剂型、诱捕器类型和利用性信息素监测、防治甜菜夜蛾技术的研究概况。认为改进现有技术后并应用于实际,将会更有效地监测和防治甜菜夜蛾的发生与危害。

Studies and application of sex pheromone production in beet armyworm, Spodoptera exigua

The beet armyworm, Spodeptera exigua (Hübner), has become a persistent pest of crop in China. It is very difficult to control once established because of its tolerance to insecticides and its location deep in the plant canopy. The major pheromone components and their activities, the more effective pheromone blend, the formulations of lures and the types of traps for the beet armyworm are reviewed. Many research results showed that sex pheromone would be more effective to monitor and survey the beet armyworm by improving present technologies and applying them in practices, and has great potential for managing this insect species by mating disruption and mass trapping.
