摘要
通过对 15个标准地的详查和 49株样木的解析 ,对南岳景区松墨天牛 Monochamusalternatus Hope的发生规律进行了研究 .结果表明 :松墨天牛的发生与萧氏松茎象 Hylobitelus xiaoi的危害成正相关 ,且萧氏松茎象危害在先 ;同一山头阴坡受害重于阳坡 ;生长势越衰弱、林地卫生越差、风大处的林分 ,松墨天牛发生越重 ,且纯林重于混交林 ;松墨天牛可危害景区内华山松、黑松、马尾松和雪松 ,且对直径 2 cm左右的小枝也蛀食危害 ;松墨天牛在华山松、黑松上的垂直分布差异不很明显 .因此 ,要控制松墨天牛的危害 ,首先必须控制萧氏松茎象的危害 ,同时还应积极采取各种有效的控制措施 .
This paper makes a study of the occurrence law of Monochamus alternatus Hope in pine stands in Nanyue Mountain by investigating 15 plots and 49 sample trees. The result shows that:(i)the occurrence of Monochamus alternatus Hopeis positively correlated with the damage caused by Hylobitelus xiaoi ;(ii) the damage on the sunny slope is lighter than on the shady slope; (iii)Monochamus alternatus Hope more easily occurs in the following stands:bad growth, bad soil hygiene, facing wind and single speices; (iv)Monochamus alternatus Hope causes damage even to little branches (D≤2 cm)of Pinus armandi, P.thunbergii Parl., P.massoniana Lamb. and Cedrus deodara Loud; (v)there is no difference in the vertical distribution of Monochamus alternatus Hope in Pinus armandi and P.thunbergii. All these may provide base data for controling this kind of forest pests.
