过来,二化螟的预测预报,主要是采用田间调查和灯下资料分析的方法。但由于气候条件和田间调查的局限性,以及电源等问题,故二化螟的发生期一般很难准确掌握。为此,我们从1978年起,开始应用性诱剂颈报二化螟第一代发生期的试验研究。经过五年实践,现已初获成效。 一、方法 1.二化 Come, the prediction of Chilo suppressalis, mainly using field investigation and lamp data analysis. However, due to the climatic conditions and the limitations of field surveys, as well as power and other issues, so the occurrence of Chilo suppressalis is generally difficult to accurately grasp. To this end, we started from 1978, the application of sexually attractant neck reported Chilo suppressalis the first generation of experimental study. After five years of practice, it has now achieved initial success. First, the method of 1. Two
