| 摘 要： | 萧氏松茎象是我国南方近年来爆发成灾的钻蛀性害虫。本文通过对固定样地的监测,研究萧氏松茎象入侵湿地松幼林的时空动态。结果表明：随着湿地松林龄的增加,萧氏松茎象幼虫危害加重,同时湿地松的耐害能力也在提高;萧氏松茎象入侵初期,主要在离虫源地较近的地方,后逐渐扩散;上坡的危害致死率超过60%,高于下坡的30%;随着林龄的增加,萧氏松茎象危害的高度也在增加。 |

| Abstract: | Hylobitelus xiaoi was a new outbreak pest in south of China.The spatial distribution of Hylobitelus xiaoi larva in the young plantation of Pinus elliottii was studied by monitoring permanent sample plots.The results showed that when the age of P.elliottii trees increased,the number of pest increased too,and also the ability to resist the pest of trees was enhanced.The pest invaded the plantation firstly which near the old place where harmed by H.xiaoi,after that invaded other places.The mortality of trees e... |
