| 摘 要： | 微红梢斑螟是南京地区重要的松树蛀梢害虫,尤其对人工火炬松幼林危害严重.对南京及周边4个不同立地条件和林型的野外试验地松林受害株率进行了调查,统计结果表明:微红梢斑螟对人工纯林危害大于天然更新林;对火炬松危害大于马尾松和黑松;此外,统计分析表明马尾松受害梢率与受害株胸径呈典型的负线性相关关系.对采集回的受害松枝室内剖查结果统计显示,火炬松受害大于马尾松、黑松和湿地松.

| Abstract: | Dioryctria rubella Hampson is a serious pine shoot and cone worm pest in Nanjing areas,especially to the young plantation of Pinus taeda.The investigations on pine tree damage rate in four sites with different conditions and forest types around Nanjing areas were carried out.The results showed that D.rubella Hampson could cause severer damage to the artificial pure plantations than the natural regeneration forest and could cause severer damage to P.taeda than to P.massoniana Lamb and P.thunbergii Parl.The significant negative linear relationship between diameter at breast height and the shoot damage rate of P.massoniana Lamb was found. |
