摘要
本文在观察泡桐大袋蛾（ＣｒｙｐｔｏｔｈｅｌａＶａｒｉｅｇａｔａＳｎｅｌｅｎ）生活史，生物学特性的基础上，通过历期法、有效积温预测法、物候预测法、回归预测法、有效基数预测等六种方法对泡桐大袋蛾发生期和发生量进行了预测预报。经验证，预测值与实际观察值吻合率达９０％以上。
Cryptothela voriegata Snellen is an important pest in paulownia forest.In this paper,it's life history and biological characteristics are observed.On this basis,the occurring stages and the amount of the month are calculated and forecasted by six methods,which are spending period,effective accumulated temperature,phenology,regression and effective base calculation methods.By testing in practice,the identical ratio between the values forecasted in theory and the values observed in practice can reach more 90 percent.
