The occurrence of third-stage larvae of the arterial worm (Elaeophora schneideri) in populations of the horse fly, Tabanus lineola hinellus, was studied on South Island, Georgetown County, South Carolina. Over the period from mid-April to mid-October 1982, horse flies had a bimodal pattern of abundance with peak populations in June and September. During individual bimonthly horse fly collections, the prevalence of infection of T. l. hinellus ranged from 0 to 1.23%. Prevalence of infected horse flies was biphasic with peaks in mid-May (1.23%) and mid-August (1.22%), 2 to 4 wk prior to peaks in horse fly populations. The intensity of infection of T. l. hinellus increased as time progressed and was highest in late summer. This increase resulted in greater recovery of infective larvae during August-September (mean intensity = 25) than in May-June (mean intensity = 4). Both prevalence and intensity of infection of T. l. hinellus were low compared to primary intermediate hosts of E. schneideri in the western U.S.
在南卡罗来纳州乔治敦县的南岛，对马蝇（Tabanus lineola hinellus）种群中动脉蠕虫（Elaeophora schneideri）第三期幼虫的出现情况进行了研究。在1982年4月中旬至10月中旬期间，马蝇的数量呈双峰模式，6月和9月种群数量达到峰值。在每次双月采集马蝇的过程中，T. l. hinellus的感染率在0至1.23%之间。感染马蝇的发生率呈双相性，在5月中旬（1.23%）和8月中旬（1.22%）出现峰值，比马蝇种群数量峰值提前2至4周。随着时间的推移，T. l. hinellus的感染强度增加，在夏末最高。这种增加导致8月至9月期间感染性幼虫的回收率（平均强度 = 25）高于5月至6月（平均强度 = 4）。与美国西部E. schneideri的主要中间宿主相比，T. l. hinellus的感染率和感染强度都较低。
