摘要
自 1997年以来 ,在沾益县菱角乡和白水镇蠹害林区内设置样地 ,通过连续几年的观察 ,对小蠹虫的生活史 ,成虫蛀梢、蛀干危害习性进行了系统地研究 ,并组建了纵坑切梢小蠹自然种群生命表 ,通过对 10 0 0hm2 的受蠹害林区的综合防治 ,平均受害株率从防治前的 6 1 5 %下降到 17 8% ,受害梢率从 34 9%下降到 10 4 % 。
The biological and damage characteristics of Tomicus piniperda have been studied by setting up experimental sites within the Tomicus piniperda damaged stand in Lingjiao Township and Baishui Town of Zhanyi County since 1997. The life history, damage habit and characteristics of the pest were systematically studied, and the life table of natural population was established. Integrated control was implemented on 1 000 ha of damaged stand. The results showed that the average damaged rate of living trees decreased from 61 5 % to 17 8 %, while that of shoots decreased from 34 9 % to 10 4 %.
