| 摘 要： | 对会泽县者海国营林场华山松木蠹象危害情况及寄主树势进行调查,结果为:2块华山松林地内,在95%的可靠性下,华山松树高、胸径、当年新抽侧梢平均长度及1000束针叶鲜重的均值差异显著,2块林地华山松木蠹象成虫危害留下的蛀食孔、流脂点及产卵痕均值差异显著.表现为华山松林树势越强,华山松木蠹象成虫蛀食孔越多,寄主流脂点越多,而树势越弱其上的产卵痕越多,使华山松木蠹象越易爆发成灾. |
| 关 键 词： | 华山松木蠹象 树势 寄主 华山松 |

| Abstract: | A study was made to understand the relationship between the occurrence of Pissodes puctatus and the growth status of the host trees through on the spot investigation on Zhehai State Forest Farm in Huize County. It was indicated that the stronger the growth status of the investigated Pinus armandii trees were, the more boring holes made by Pissodes puctatus adults and more resin leaking points were found on the trunk of the host trees. It was also showed that the weaker the growth status of the investigated Pinus armandii trees were, the more oviposition traces were found on the host tree trunk, which would forecast the possibile outbreak of the Pissodes puctatus pests. |
| Keywords: | Pissodes puctatus tree growth status host Pinus armandii |
