摘  要：
松叶蜂属膜翅目(Hymenoptera)广腰亚目(Symphyta)松叶蜂科(Diprionidae),主要以幼虫为害针叶树种,严重发生时针叶树种受害率达80%以上,给林业生产造成严重的经济损失。采用样方法就不同林分、坡位、海拔对松叶蜂幼虫虫口密度的影响进行了研究,分析了松叶蜂幼虫虫口密度与环境因素之间的相关性。结果表明,松叶蜂幼虫在针叶纯林的虫口密度显著高于针叶阔混交林的虫口密度;海拔高度与松叶蜂的虫口密度具有显著正相关性;阴坡松叶蜂幼虫虫口密度明显高于阳坡。研究结果可为松叶蜂的综合治理提供理论依据。

摘  要：
Diprionidae of Symphyta(Hymenoptera)is mainly contaminated with larvae, and the damage rate of conifers is more than 80%, which has brought serious economic losses to forestry production. In this study, the effects of the stand, slope locations, and elevations on the population density of Pine Sawfly larvae were studied using the sampling method, the correlation between the population density of Pine Sawfly larvae and the environmental factors was analyzed. The results showed that the density of Pine Sawfly larvae in pure coniferous forests was significantly higher than that of coniferous and broad-leaved mixed forests. There was a significant positive correlation between altitude and the density of larvae. The population density of Pine Sawfly larvae in shady slope was significantly higher than that in sunny slope. This study provides a theoretical basis for the comprehensive management of Pine Sawfly.
