| 摘 要： | 对湘西南山区马尾松毛虫发生规律与环境因子关系进行了分析，发现在山区温、湿度和降雨量对马尾松毛虫发生都有影响，但不是单因子发生主要作用；在山区南坡山脊、林缘、8～15年树龄的松树中马尾松毛虫分布较多；海拔500m以下、东坡和干燥林地中的松林，马尾松毛虫为害严重，纯林和混交林为害同等严重。

| Abstract: | The occurrence law and environment factor of Dendrolimus punctarus in southwest of Hunan Province were studied.The effects of occurrence were based on temperature,humidity and rainfall in mountain area,but not mainly effected by one factor.D.punctarus was mainly distributed in 8 to 15 years old trees in ridge and forest edge of south slope of mountain area.The obvious damage by D.punctarus areas were in less 500 meter altitude,east slope and dry forest land,and the same damage level occured both in pure and... |
