经1982年至1986年研究资料统计和分析,建立了蜀柏毒蛾发生期期距表、回归预测式和物候预测表.通过验证,预报结果与实际发生期基本吻合.蜀柏毒蛾Parocneria orientu Chao是我省柏木林区的灾害性虫种之一,经常危及川北、川中.为准确地预测其发生期,给防治提供可靠依据,1982年至1986年间,我们在阆中方山乡对其发生期进行了研究,现将结果整理如下:
Based on the statistics and analysis of the research data from 1982 to 1986, the interval table, the regression prediction table and the phenological forecast table were established. The results of the prediction are basically consistent with the actual occurrence period. Parocneria orientu Chao One of the catastrophic insect species in the Kashiwagi forest area of our province often endangered northern Sichuan and Sichuan provinces. In order to predict its occurrence accurately and provide a reliable basis for prevention and treatment, from 1982 to 1986, The study, the results are summarized as follows:
