摘　　要：根据有关调查资料,应用正态分布模型模拟了水稻秧田第一代灰飞虱成虫的发生量,推算得到的第一代成虫高峰期后的灰飞虱理论发生量与实际发生量吻合。On the basis of the relative survey data,the adult density of Laodelphax striatellus in the first generation in rice seedling field was simulated by using normal distribution model,and the predicted theoretical adult density of Laodelphax striatellus after the peak stage of the first generation was coincided with the real one.
