摘　　要：国槐、龙爪槐是重要的园林绿化树种，近年来常遭到槐尺蛾的严重危害，影响绿化效应和观赏价值。该虫每年发生６代，蛹重为（０．１９２３±０．０３２５）ｍｇ／只；产卵量为（６３６．４３±２１９．７６）粒。经多代饲养测定，蛹的发育起点温度Ｃ＝（１３．１０±１．５９）℃，有效积温Ｋ＝９２．１６±４．２５（ＤＤ）；卵发育起点温度Ｃ＝（１３．１３±１．７５）℃，有效积温Ｋ＝５４．５９±２．５７（ＤＤ）。由此建立数学预测式经１９９７年的验证，其结果符合实际情况。Semiothisa cinerearia Bremer et Grey can hatch six generations in one year.One female pupa weight about 0 1923±0 0325 mg and can lay 636 43±219 76 eggs.After raising the insects at various temperature for several generations,it was found that the necessary intial temperature for pupa development was C=13 10±1 59(℃) and the effective accumulated temperature K=92 16±4 25 (DD).For egg development,C=13 13±1 75 (℃),K=54 59±2 57 (DD);In consequence,the equation can be established as follows:N pupa =92 16±4 25T-(13 10±1 59),N eggs =54 59±2 57T-(13 13±1 75).
