摘要
为有效防控新疆塔城地区流行的一种不明绵羊外寄生虫病,本实验通过眼观、解剖镜、数码显微镜观察对该寄生虫进行形态学分类和鉴定研究。结果表明,蚤体大小6 mm～8 mm,饱血后12 mm～15 mm,头胸部占整个体长的10%左右。头胸黑褐色,腹部白色略灰;体表有稀少的鬃毛,无额突,下唇须节数17～22节。3对足,后足胫节依次着生1 2 2 2根粗鬃,中间腹节背板气门稍大于眼。从形态学鉴定该外寄生虫属于蠕形蚤科(Vermipsyllidae)长喙蚤属(Dorcadia)的羊长喙蚤(D.ioffi),但与典型的羊长喙蚤存在形态学差异,该长喙蚤是否为新的亚种或变种尚待进一步研究。
To identify and classify a newly emerged flea which is parasiting in sheep and causes unknown sheep parasitic disease in Tacheng region of Xinjiang, the morphological classification and identification results showed that the body size of flea was 6 mm to 8 mm, and 12 mm to 15mm after the blood-sucking. The head and chestwas in dark brown colour, account to about 10 % of the total body length, while the belly was a little gray. The body surface contains with sparse mane, but without amount of protrusion. There were 17 to 22 sessions in lower lipbe. The parasite had 3 pairs of legs, hind tibia followed by the 1 2 2 2 thick mane. The back valve in middle section was slightly larger than ventral eye. The results showed that the ectozoic parasite is Dorcadia ioffi, which is subordinated to Vermipsyllidae, Dorcadia. However, the morphological features was different between this flea and typical Dorcadia iofli, which need to be further studied.
