甘蔗二点螟的发生预测,过去是采用田间幼虫化蛹进度方法,调查费工费时效率低。1976年我们开始试验,利用二点螟活雌蛾释放外激素诱捕雄蛾,了解二点螟在当地发生的始盛期,以指导适时施药防治。试验结果表明,利用二点螟活雌蛾诱捕雄蛾与田间成虫消长动态基本一致,以此掌握的发蛾 Predict the occurrence of sugarcane two-spot borer, the past is the use of field larvae pupation progress method, the cost of investigation time-consuming low efficiency. In 1976 we started the experiment, the use of two spotted moth live pterostilles released pheromone trapping male, to understand the initial occurrence of the borer at the beginning of the spot, in order to guide the timely application of pesticide control. The experimental results show that the use of two-spotted moth live moth trapping male and female dynamics of growth and development are basically the same, in order to grasp the hair moth
