三化螟Tryporza incertulas(Walker)在生长发育过程中,环境温度起着重要的作用。前人已研究了三化螟的个体发育与有效积温的关系。日人藤家梓通过对梨潜叶蛾Buccuratrixpyrivarella Kuroko的研究,发现该虫测灯下各世代诱获的累积成虫数量的百分比的概率单位值与有效积温呈直线相关关系。 本文试图通过对始兴县历年测灯下各世代三化螟蛾诱获累计量的百分比的概率单位值与 Tryporza incertulas (Walker) In the growth and development process, the ambient temperature plays an important role. Previous studies have studied the relationship between individual development and effective accumulated temperature of Borer. The study on Buccuratrix pyrivarella Kuroko by Japanese rattan house, found that there was a linear correlation between the probability unit of the percentage of accumulated adult traps captured by each generation under the lamp and the effective accumulated temperature. This article attempts to Shixing counties over the years under the lamp of the three generations of moths induced by the cumulative amount of the percentage of the unit of probability and
