Forty-one imperial shag chicks were sampled for lice during the breeding season of 2014 in Punta León, Argentina. We found 2 lice species, infesting the body and present in the oral cavity of the birds. This constitutes the first host record for and the first record for the continental Argentina for . Ninety-three percent of the chicks were infested by at least one lice species. . was present in all of the lousy chicks, while infested 84.2% of them. The mean intensity was 29.5 and the range 1-129. There was no difference in prevalence, mean intensity or mean abundance between louse species. However, we found differences among the pattern of infestation of each species. Imperial shag chicks were infested by their parents during their first days of life by , mainly in nymphal stage and by as adult lice. Our results showed differences among lice species that could be related to the restrictions that lice from seabirds faced during their life cycle.
2014年繁殖季节，在阿根廷蓬塔莱昂对41只皇家鸬鹚雏鸟进行了虱子采样。我们发现了2种虱子，一种寄生于鸟的身体，另一种存在于鸟的口腔。这是[第一种虱子名称]的首个宿主记录，也是[第二种虱子名称]在阿根廷大陆的首个记录。93%的雏鸟至少感染了一种虱子。[第一种虱子名称]在所有感染虱子的雏鸟中都有发现，而[第二种虱子名称]感染了其中84.2%的雏鸟。平均感染强度为29.5，范围为1至129。两种虱子在感染率、平均感染强度或平均丰度上没有差异。然而，我们发现每种虱子的感染模式存在差异。皇家鸬鹚雏鸟在出生后的头几天被其父母感染了[第一种虱子名称]，主要是若虫阶段，被[第二种虱子名称]感染时为成虫。我们的结果显示，虱子种类之间存在差异，这可能与海鸟虱子在其生命周期中面临的限制有关。
