Abstract In this study, we provide the first genetically verified distribution record beyond its native range of Ligula pavlovskii, a high-impact endoparasite of Ponto-Caspian gobies. According to parasitological surveys, ligulosis was detected for the first time in monkey goby individuals collected from Lake Balaton in 2004, 34 years after the first record of monkey goby in the lake. During a Lake Balaton survey in 2018, we detected tapeworms in 44.4% of the sampled monkey gobies. This prevalence is about two to ten times higher than it was reported from within the native range of the fish hosts. The same survey revealed an uneven spatial distribution of the ligulosis in the monkey gobies inhabiting different shoreline sections of the lake. We assume that the occurrence and recent distribution data of this high-impact endoparasite may provide useful information for potential biocontrol measures of invasive Ponto-Caspian gobies in the future.

首次通过基因验证发现 Ligula pavlovskii 在其原生范围之外出现及其在 Neogobius fluviatilis 中的感染特征

摘要 在这项研究中,我们提供了第一个经过基因验证的分布记录,超出了 Ligula pavlovskii 的原生范围,这是一种高影响力的 Ponto-Caspian 虾虎鱼体内寄生虫。根据寄生虫学调查,2004 年在巴拉顿湖采集的猴虾虎鱼个体中首次检测到舌鱼病,这是在该湖首次记录猴虾虎鱼后的 34 年。在 2018 年巴拉顿湖调查期间,我们在 44.4% 的采样猴虾中检测到绦虫。这种流行率比从鱼类宿主的本地范围内报告的高出大约两到十倍。同一项调查揭示了栖息在湖泊不同海岸线部分的猴鱼虾虎鱼的舌苔的空间分布不均匀。
