甘蔗螟虫性诱测报,通过逐日性诱蛾量累加数占全代蛾量的百分率来确定螟蛾高峰期,进行短期预报,准确度高,切实可行。但要待全代蛾量结束再推算蛾量高峰期,从时间上说有所被动。笔者根据近年工作实践,认为越冬代条螟成虫发生期与3月份平均气温关系密切,试将广西博白、柳城两县1986—1990年越冬条螟蛾量(实测值)和3月份平均气温
Sugarcane borer induced insects, reported by the cumulative number of daily sucking moths accounted for the percentage of the entire generation of moths to determine the peak moth moth, for short-term forecast, high accuracy, practical. However, the amount of moths to be the end of the rest and then calculate the peak amount of moths, from time to say that some passive. According to the practice of recent years, the authors believe that the incidence of overwintering adult striped borer adults and the average temperature in March close to the trial in Guangxi Bobai, Liucheng two counties 1986-1990 overwintering moth moth quantity (measured value) and the average temperature in March
