普通黑光灯对稻纵卷叶螟和稻飞虱的诱虫量与气象因子的相关分析

Correlation between the Ordinary Black Light Induced Medinalis and Planthoppers Insects' Volume and Meteorological Factors

以1991年至2008年广东省恩平市的观测数据,分析了普通黑光灯对稻纵卷叶螟和稻飞虱诱虫量与气象条件的相关性。结果表明:稻纵卷叶螟蛾年总诱量与年总降雨量呈正相关,稻飞虱成虫年诱量与年降雨量呈负相关,稻纵卷叶螟蛾与主要为害的5、6、8月降雨均呈正相关,与7月降雨则呈负相关;稻飞虱与5、7、8月降雨均为负相关,与6月降雨为正相关。此外,热带气旋个数与稻飞虱年诱虫量呈负相关;与稻纵卷叶螟蛾年诱虫量呈正相关。综合分析表明,稻纵卷叶螟蛾与稻飞虱与气象因子比较有较大的差别,对普通黑光灯诱虫量有极大的影响,可间接预测预报两迁飞性害虫的发生量,为准确预测预报两迁害虫为害提供参考。

Basing on the observational data, the correlation between the ordinary black light induced Medinalis and planthoppers insects＇ volume and meteorological factors was studied. The results show that the annual total inducement volume of medinalis moth （planthopper） and the annual precipitation are positively （negatively） correlated. The damage from medinalis moth （planthoppers） is positively correlated with the rainfall of May, June, August （May, July, August）, and negatively correlated with that of July （June） ; the number of tropical cyclones has a negatively （positively） correlation with the inducement volume of medinalis moth （planthopper）.
