根据有效积温和发育起点温度对落叶松鞘蛾蛹和卵发生期提出预测式,其蛹的有效积温的估计区间为63.9±9.7日度,发育起点温度的估计区间为14.6±1.1℃,卵的有效积温的估计区间为279.7±22.8日度,发育起点的估计区间为15.7±0.6℃。蛹期预测式为(?)=(63.9/(T-14.6))±1.9069(SNp=0.7417,自由度为5)卵期预测式为(?)=(279.7/(T-15.7))±3.7932(SNe=1.6039,自由度为7) Based on the effective accumulated temperature and developmental starting temperature, the predicted period of pupal and egg development of C. larvae was predicted. The effective accumulated temperature of pupae was estimated to be 63.9 ± 9.7 days, and the estimated starting temperature was 14.6 ± 1.1 ℃. The estimated effective accumulated temperature is 279.7 ± 22.8 day, and the estimated interval of developmental start is 15.7 ± 0.6 ℃. The predicted pupal period was (?) = (63.9 / (T-14.6) ± 1.9069 (SNp = 0.7417, 5 degrees of freedom) (SNe = 1.6039, degree of freedom of 7)
