| 摘 要： | 华山松松茎象是南岳景区松树上新发现的一种重要害虫,该虫严重危害华山松和黑松.本文介绍了其幼虫的取食危害特点及防治方法.该虫幼虫取食华山松和黑松的韧皮部,同时取食新鲜的松脂,越冬后的幼虫仅靠取食新鲜松脂就能正常发育,并化蛹、羽化.单株虫口数量与松树树干基部直径呈明显正相关,即树干基部直径在10.0~20.0 cm 、20.1~25.0 cm 、25.1~35.0 cm之间的松树,平均单株有虫数量分别为1.0头 株-1、1.98头 株-1和3.30头.株-1.在5~10月间,采用人工清除幼虫的方法可有效地控制该虫的危害,采用化学药剂防治该虫效果不明显.

| Abstract: | Hylobitelus sp. is a newly-found pest-insect on pine-trees in Nanyue Mounts, Hunan province and seriously harms Pinus amandi and P. Thunbergii. Its feeding habits and injury and control methods are introduced. Its larvae feed on fresh pine-resin while boring into the pine phloem. After passing through winter, the larvae can normally develop, pupate and become imago, living on only the fresh resin. The insect number per pine is positively correlated with the diameter of pine trunk near ground, i.e. the pine with the ground diameter of 10.0~20.0 cm, 20.1~15.0 cm and 25.1~35.0 cm is bored respectively by 1.0, 1.98 and 3.30 larvae. From May to October, it can effectively control this pest-insect to clear away the larvae feeding on pine by manual work. |
