摘　　要：临床检查了牦牛和黄牛体内寄生的牛皮蝇蛆 ,其寄生率分别为 84.2 5 %和 70 .2 8% ,寄生强度分别为 18.3 2个和 2 .17个 ;剖杀检查牦牛 114头 ,寄生率为 10 0 % ,寄生强度为 71.66个。经鉴定 ,牛皮蝇的种类有牛皮蝇 (Hypodermabovis)、纹皮蝇 (H .lineatum )和中华皮蝇 (H .sinense) 3种。弄清了牛皮蝇各期幼虫在牛体内的寄生季节、寄生部位、移行动态、三期幼虫寄生方位、入土化蛹羽化规律、成蝇活动规律等。药物防治试验证明 ,Ivomec注射液和国产的阿福丁片均是杀灭牛皮蝇蛆的首选药物。Clinical examination showed the parasitic rates of Hypoderma in yaks and cattles on the northwest grassland in Sichuan province of China are 84.25% and 70.28% respectively and the parasitic intensity is 71.66.According to identification of morphology and biochemical characteristics of Hypoderma, its varieties on the grassland are H.bovis, H.lineatum and H.sinense.The occurring seasons,parasitic positions and moving tendency of the larvas of Hypoderma in different phase inside the bovine bodies are cleared, and the parasitic patterns of larvas in third phase and the regular pattern of larvas pupation ,sclosion and the adult's movement are revealed .The prevention and treatment test of hypodermiasis showed that Ivomec made in America and Afuding made in China are the best drugs for killing Hypoderma.
