| 摘 要： | 通过研究落叶松叶蜂卵期的种群数量动态，以卵梢占新梢总量的百分率作为其种群数量的指标值，给出了以种群趋势指数法、灰色预测法建立的发生量经验预测模型。同时据有效积温、及物候建立了发生期预测经验模型。

| Abstract: | Using the percertage of ovum top to young tep as an population density index, an experiential prediction model of population flucuation of pristiphora erichsonii(Hartiy) was setablished based on the population fluctuation and Fuzzy mathods, while a prediction model of occuring time was also established based on the effctive accumulated temperature and the phenophase of larch. |
