摘　　要：本文研究了茶卷叶蛾在不同温度下的发育历期、发育起点温度和有效积温,结果表明,在18~30℃范围内,茶卷叶蛾的发育历期随温度的升高而缩短,蛹、幼虫、卵的发育速率与温度呈极显著的正相关(P<0.01),茶卷叶蛾卵、幼虫、蛹的发育起点温度分别为9.48℃、6.13℃、7.95℃,有效积温分别为102.86日·度、492.32日·度、138.67日·度。Duration,threshold temperature and effective accumulated temperature for various developmental stages of Homona coffearia Nietner were investigated.The duration of each stage could be significantly shortened with increasing temperature from 18℃to 30℃(P<0.01).The threshold temperatures to initiate the developments of eggs,larvae,and pupae were 9.48℃,6.13℃and 7.95℃,respectively;and the effective accumulated temperatures for them,102.86,492.32 and 138.67 degree-days,respectively.
