角蝇及其防制

角蝇是一种广泛存在于欧洲、亚洲及南美北美地区且危害性严重的经济性害虫，可通过叮咬吸血对畜牧业造成重大经济损失，也可作为媒介生物在畜群间传播病原体。实际生产中，根据角蝇具有在牛粪中产卵的生活习性，粪便排泄物或直接被清除，或被掺入多拉菌素、伊维菌素等以杀死角蝇幼虫。而控制成蝇则多采用化学手段，其中耳标式杀虫剂由于其防制效率高、防制周期较长、用药量低等特点，近些年来得到广泛应用。本文结合近几年国内外相关文献，对角蝇的生物学特性、危害以及角蝇综合防制展开综述，为角蝇防制提供理论基础。

Horn fly and its control

The horn fly is a serious economic pest that is widespread in Europe, Asia, South America and North America. It can cause significant economic losses to the animal husbandry by biting and sucking blood, and can also function as a vector to spread pathogens between herds. Since horn flies usually lay eggs in cow dung, the excrement is either removed directly or mixed with doramectin, ivermectin, etc. to kill horn fly larvae. Chemical methods are mostly used to control adult flies. Among them, ear tag insecticides have been widely used in recent years due to their high control efficiency, long control cycle, and low dosage. This article combines the relevant domestic and foreign literatures in recent years to summarize the biological characteristics, hazards and integrated control of horn flies, and provides a theoretical basis for the control of horn flies.
