红壤低丘地区马尾松毛虫防治研究

Studies on the Control of Dendrolimus puntatus in Red Soil Low Hilly

分析总结万年县马尾松林试验区马尾松毛虫近20多年来的为害情况及防治措施,提出封山育林,营造混交林,改变森林结构,并结合生物防治的综合措施来防治马尾松毛虫。实践证明这一方法可以长久控制松毛虫的为害,又可保持水土、改善生态环境,为红壤低山丘陵区马尾松毛虫防治的有效策略。

The damage and control measures of Dendrolimus puntatus in the experimental area of Pinus massoniana forests in Wannian County since the past 20 years were summarized in this paper,a proposal that integrated measures including closing the hillsides to facilitate plant growth,establishing mixed forests and changing forest structure as well as biological control were put forward in order to control D.puntatus.Practices have proved that these methods can be long-term control the D.puntatus,but also maintain soil water and improve the ecological environment.It was an effective strategy for prevention and control of D.puntatus in red soil low hilly region.
