黑云杉蚜Cinara piceae Panzer属同翅目,大蚜科,长足大蚜属。分布于四川省甘孜、阿坝藏族自治州的高山针叶林区。我们于1980年在丹巴地区进行人工林病虫普查时发现该虫。黑云杉蚜为害云杉属的鳞皮云杉Picea aurantiaca var. retroflexa(Mast.)C.T.Kuan和粗枝云杉Picea asperata Mast.的幼树。 丹巴地区海拨2,500—3,800米处的云杉人工林均受到不同程度的为害,单株虫口密度在千头以上,平均有虫株率达43.％。成、若蚜群集云杉主干四周为害,寄主被害后,生长势普遍减弱,年高生长下降51.7％。1981至1983年,我们对
The black aphid Cinara piceae Panzer is a Homoptera, aphididae, large aphid. Distributed in Ganzi, Sichuan Province, Aba Tibetan Autonomous Prefecture of the coniferous forest area. We found it in a census of plantation diseases and pests in the Danba area in 1980. Black spruce aphid infestation Picea spruce Picea aurantiaca var. Retroflexa (Mast.) C.T. Kuan and rough spruce Picea asperata Mast. Spruce plantations at the altitude of 2,500-3,800 meters in Danba area were damaged to varying degrees. The density of insect population per plant was over one thousand, with an average of 43.% of the strains. As, if the aphid cluster spruce trunk around the damage, the host killed, the general decline in growth potential, the growth of 51.7% decline. From 1981 to 1983, we were right
