虱是禽鸟体表的永久寄生性昆虫,具有严格的宿主特异性和一定的寄生部位。以啮食羽毛、皮屑为生。当家禽遭受虱类的严重侵袭时,由于患禽常因啄痒而伤及皮肉,精神不安、食欲不振、羽毛脱落、机体消瘦、生产性能降低。对雏禽危害尤为严重,可造成雏禽生长发育停滞,体质日衰,甚至死亡。为了摸清我省家禽虱类的虫种、分布及其危害情况,为制订防治措施提供科学依据,我们对本省有代表性地区的家禽虱类进行了调查。现将非常见几种家禽虱类报道如下。 Louse is a permanent parasitic insect on bird body surface with strict host specificity and certain parasitic sites.
