A face fly (Musca autumnalis) population near Wetaskiwin, central Alberta, Canada, was sampled 9 times from 26 July to 29 September 1988 for the early larval stages of Thelazia spp. Of 426 female flies examined, 159 (37%) contained Thelazia spp. (almost exclusively T. skrjabini), with an average worm burden of 4.2 larvae per infected fly. Prevalence ranged from 17 to 56% over 9 collections. This is the first report of Thelazia skrjabini in flies from western North America and the highest Thelazia prevalence in face flies yet reported in North America. The face fly population was also parasitized by Heterotylenchus autumnalis, with a prevalence of 5.5%.
1988年7月26日至9月29日期间，在加拿大艾伯塔省中部韦塔斯基温附近对厩螫蝇（秋家蝇）种群进行了9次采样，以检测吸吮线虫属的早期幼虫阶段。在检查的426只雌蝇中，159只（37%）含有吸吮线虫属（几乎全是斯氏吸吮线虫），每只受感染的蝇平均有4.2条幼虫。在9次采集过程中，感染率在17%至56%之间。这是北美西部苍蝇中首次报告斯氏吸吮线虫，也是北美迄今报告的厩螫蝇中吸吮线虫感染率最高的。该厩螫蝇种群还受到秋季异皮线虫的寄生，感染率为5.5%。
