越冬代二化螟灯下成虫代表量和二代稻苞虫花圃成虫发生量的群体动态,均属企态分布,利用前期成虫代表量来预报当代成虫发生总量,不但准确、迅速、经济,而且对下一代幼虫的发生量及危害程度的预报也起着决定作用。具体方法是:越冬代二化螟成 The population dynamics of lamppost adult light and lamppost adult population in the second generation of rice borers are state distribution, the use of the amount of early adult representatives to predict the total amount of adult adults, not only accurate, rapid, economic, But also plays a decisive role in forecasting the occurrence and the degree of harm of the next generation larvae. The specific method is: overwintering Chilo suppressalis into
