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 developmental rate of pupal growth of HomonaissikiiYasuda was observed at five kinds of constant temperature. The developmental threshold temperature (C) of pupal stage of Cryptomeria fortunei was 125 ℃ and the effective accumulated temperature (K) was measured by “least square method” For 89 2 3 days.
