| 摘 要： | 观察研究结果表明,茶尺蠖(Ectropis Obliqua Prout)各虫态发育历期随着温度的上升而缩短,发育速率则随着温度的升高而加快,并探明了各虫态历期与期内均温之间的曲线关系模型。同时,用加权法和回归直线法分别计算了各虫态的发育起点温度和有效积温常数,结果表明两种方法计算的数据间差异不显著,表明两方法均可采用。验证结果表明,利用各虫态的发育起点和有效积温,推算茶尺蠖的发生代数及各虫态的发生期,与实际发生情况基本吻合。

| Abstract: | The developmental duration of each developmental stage of tea geometrid(Bctropis obliqua Prout)shortened and the development rate increased withthe increasing of temperature.Equation of the relationship between deve-lopmental duration and mean temperature was obtained,The temperaturethresholds for development and the effective accumulated temperatures calcu-lated from the weighting and the regression methods were not of significantdifference.The generations and the occurring period of each developmentalstage calculated from the temperature threshold and the effective accumulatedtemperature agreed well with the observed. |
