【目的】旨在了解新疆昭苏县羊群中羊虱蝇的形态特征及其流行状况，为昭苏县羊虱蝇的防控提供科学依据。【方法】通过在昭苏县天山乡、76团和74团的156只羊中采集虫体样本，并运用体视显微镜进行形态学鉴定，用描述性统计方法分析羊虱蝇的感染率。【结果】研究显示，对受试的156只羊采集的虫卵样本，通过形态学分析证实所有采集的样本均为羊虱蝇，总体感染率为62.8%，其中天山乡的羊只感染率最高。研究还发现羊虱蝇感染在不同地理位置、不同性别及不同年龄群体间呈现一致性、普遍性。【结论】本研究明确了昭苏县羊虱蝇的流行状况和形态学特征，为制定有效的羊虱蝇防控措施提供了数据信息，对提升羊群健康水平，提高生产效率，减少经济损失具有一定意义。

【Objective】The aim of this study was to analyse the morphological characteristics of Melophagus ovinus and its epidemiological status in sheep flocks in Zhaosu County,so as to provide a scientific basis for the prevention and control of sheep Melophagus ovinus. 【Methods】Sheep Melophagus ovinus samples were collected from 156 sheep in the flocks of Tianshan Township,76th Regiment and 74th Regiment in Zhaosu County,and morphological identification was carried out by using somatoscopic microscope,while descriptive statistical methods were applied to analyse the infection rate of sheep Melophagus ovinus.【Results】The overall infection rate of sheep Melophagus ovinus was 62.8%,with the highest infection rate in Tianshan Township. Morphological analysis confirmed that all collected specimens were sheep Melophagus ovinus. In addition,the study found that sheep Melophagus ovinus infection showed consistency across geographic locations,sheep sex and age groups,indicating the prevalence of sheep lice fly infection.【Conclusion】This study clarified the epidemiological status and morphological characteristics of the sheep Melophagus ovinus in Zhaosu County,which provided important information for the development of effective sheep lice fly prevention and control strategies,and is of great significance for improving the health of sheep and their production efficiency,and reducing economic losses.
