云杉大小蠹的危害特征及不同防治方法的防治效果
Damage characteristics of Dendroctonus micans and control effect of different methods
摘要
Abstract
To identify the damage of Dendroctonus micans against Picea crassifolia and Picea purpurea and control effect of different methods against D.micans,the damage characteristics of D.micans were investigated in field,the scrape bark and pesticide treatments were used for control experiment.The results showed that P.crassifolia and P.purpurea could be infested by D.micans,and the infested rate of P.crassifolia was higher than that of P.purpurea;the main infested parts of the trunk of P.crassifolia were below 2.5 m,and the tree height range of 10-25 m and diameter range of 20-45 cm were susceptible by D.micans attacked;and the damage rate of D.micans was negatively correlated with canopy density.The control effect of scrape bark was 100%,and the control effects of trunk drilling and spraying were more than 95%.The results can provide basic support for ecological research and control of D.micans.关键词
