本文试通过柳州地区农科所历年测灯下各世代三化螟蛾诱获累计量的百分比的概率值与该地有效积温关系的分析,探求有效积温对三化螟种群变动的影响,以便利用有效积温量作为各世代三化螟发生期和发生量的一种预测方法;并探测各世代自然种群发育所需的热常量估计值。
In this paper, we analyzed the relationship between the probability of accumulated cumulated amount of Pythium fumigatus and the effective accumulative temperature of the stem borer, The effective accumulated temperature is used as a prediction method for the occurrence and occurrence of the three generations of rice stem borer (Chilo suppressalis); and the estimation of the thermal constant needed for the natural population development of each generation is probed.
