冷杉迹球蚜属球蚜科,迹球蚜属的一新种。在四川西部山地,海拔2000—3000米的高山林区,均有发生。它的第一寄主为丽江云杉(Pieea likangensis (Frack) Pritz。川西云杉P, likida-ngensis var balfouriana Cheng ek Hu。麦吊杉P、 brachytyla (Fritz)Pritz和紫果云杉P、Purpurea mast,第二寄主为冷杉Abies fabri (mast) Craib。冷杉幼苗幼树受害后影响生长,严重时造成树势衷弱。云杉类受害后,可造成小枝枯死。1978—1979年,我们在宝兴硗碛的柳落沟工段,对此球蚜的友生规律进行了观察试验。现将结果整理于后。
A new species of the genus Aphididae from the field of Aphididae. In the mountains of western Sichuan, 2000-3000 meters above sea level in the mountains, have occurred. Its first host is Pieea likangensis (Frack) Pritz. Picea abortiflora Cheng Cheng Huk P, brachytyla (Fritz) Pritz and Picea purpurea mast , And the second host was Abies fabri (mast) Craib. The seedling of fir seedling affected the growth after it had been harvested, and the tree seedlings were seriously weakened. After the spruce had been damaged, it could cause the branchlet to die. From 1978 to 1979, Qiu moraine willow off section of the ball aphid Friends of the law observed and tested the results are now sorted out.
