赤松毛虫出蛰时间与每年2月中旬至3月上旬的旬均积温有显著的相关性,据调查得出,其关系式为(?)。赤松毛虫发生量与每年11月至翌年3月上旬的旬均温有显著的相关性,据在当地调查得出,其相关方程为(?)。用这两个公式预测的发生期和发生量,其误差为1.8163和±8.5584,可供生产上进行赤松毛虫的发生期、发生量的预测。 Dendrolimus cinnabarinus sting out time and mid-February each year to early March the ten-day average temperature was significantly correlated, according to the survey, the relationship (?). The occurrence of Dendrolimus punctatus is significantly related to the average temperature of ten days from November to early March each year. According to the local survey, the correlation equation is (?). Using these two formulas to predict the occurrence and the amount of occurrence, the error is 1.8163 and ± 8.5584, which can be used for the prediction of the occurrence and the occurrence of Cicada caterpillar.
