中文摘要：采用19，22，25，28和31℃ 5个温度对竹织叶野螟Algedonia coclesalis Walker各虫态（龄）发育起点温度和有效积温进行测定。结果表明，竹织叶野螟的在19～31℃范围内均能正常生长发育，尤其是28～31℃范围最适宜于竹织叶野螟的生长发育。卵、1龄幼虫、2龄幼虫、3龄幼虫、4龄幼虫、5龄幼虫、6龄幼虫、7龄幼虫、蛹、成虫及世代的发育起点温度分别为6.63，12.51，11.18，10.93，10.05，8.01，6.80，5.78，6.20，7.81和8.33℃，有效积温分别为124.19，64.54，72.59，82.08，93.46，136.84，155.42，201.06，211.55，111.49和1 235.50日·度。
英文摘要：The developmental threshold temperature (DTT) and effective accumulated temperature (EAT) of Algedonia coclesalis Walker were determined under five constant temperatures in the range of 19～31℃. The results showed that egg, larva, pupa and adult can normally develop between 19～31℃. The optimal temperatures of the growth and development were between 28～31℃. The DTT of egg, each instar larvae from the 1st instar to the 7th instar, pupa, adult and the yearly generation were 663, 1251, 1118, 1093, 1005, 801, 680, 578, 620, 781 and 833℃, respectively, and their EAT were 12419, 6454, 7259, 8208, 9346, 13684, 15542, 20106, 21155, 11149 and 1 23550 degree -day respectively.
