摘要：通过解剖国槐Sophora japonica受害木,结合林间调查,分析锈色粒肩天牛Apriona swainsoni幼虫在国槐树干上的分布,建立幼虫虫口数量预测数学模型。结果表明,锈色粒肩天牛幼虫主要分布于国槐主干2 m以下的位置,中、老龄幼虫主要危害寄主的边材部位。以新排粪孔与解剖木实际带虫数量建立4个虫口预测模型方程,经方差检验均可靠有效。
To analyze the distribution of A. swainsoni larva on Sophora japonica and establish mathe- matical model for predicting the larva population, infested tree dissection and investigation in forest was made. The results showed that A. swainsoni larvae mainly lived in the trunk below 2 m, the middle and aged larvae mainly damaged on the host sapwood. Based on the correlation between new excretion holes and the actual number of insect in the anatomized wood, four population prediction models were estab- lished, and the variance test was reliable and effective.
