摘要
在 5种恒定温度下观察了柳杉长卷蛾HomonaissikiiYasuda蛹的生长发育速率 ,应用“最小二乘法”测得柳杉长卷蛾蛹期的发育起点温度 (C)为 12 5℃ ,有效积温 (K)为 89 2 3日度。
The development rate of the pupa of Homona issikii Yasuda was observed at 5 different constant temperatures under laboratorial condition.The results showed that the threshold temperature was 12.5℃ and the effective accumulated temperature was 89.23 day degree.
