| 摘 要： | 云杉树叶象(Phyllobius sp.)1984～1986年在黑水县林区的苗圃地及附近的更新幼树上普遍发生,苗木受害后似火烧状。该虫一年发生一代,以老熟幼虫越冬。翌年4月中下旬在土室内化蛹,成虫于5月上旬羽化。并出土行补充营养,危害苗木嫩梢及芽苞,啃食针叶成缺刻状。5月下旬交尾产卵,6月中旬幼虫孵化危害苗木根皮,幼虫危害期长达280多天。通过对此虫的防治试验研究,取得了较好的效果,探讨出了有效的防治方法。本文就此虫害提出综合防治方法及防治意见。

| Abstract: | This paper reports the severe infestation of spruce leaf weevil (phyllobius sp.) on the spruce seedling and its young trees over the forest area of the county.The biological char- acteristics of the pest has been described,and an integrated control measure against the weevil has been suggested on the basis of promising results of field control tests. |
