Abstract

The lice parasite community of great grey shrike Lanius excubitor collected in NE Slovakia during 1962-1974 was quantitatively studied. Lice fauna comprised of three species: Docophorulus coarctatus, Bruelia cruciata (Ischnocera) and Lanicanthus camelinus (Amblycera). All these species were previously indicated as characteristic for that host. The prevalence of lice was high--lice were recovered from 96.3% (n=108) host specimens. Distributions of lice on the great grey shrike, a strictly territorial bird, were aggregated, indicating substantial variation in the abundance of lice. Sex ratios of lice were biased towards females and not correlated with the subpopulation size of lice on individual hosts.

摘要

对1962年至1974年期间在斯洛伐克东北部采集的大灰伯劳（Lanius excubitor）的寄生虱群落进行了定量研究。虱类动物群由三种物种组成：紧缩多肋虱（Docophorulus coarctatus）、十字布鲁氏虱（Bruelia cruciata，长角鸟虱科）和骆驼兰虱（Lanicanthus camelinus，短角鸟虱科）。所有这些物种以前都被认为是该宿主的特征物种。虱的感染率很高——从96.3%（n = 108）的宿主标本中发现了虱。虱在大灰伯劳（一种严格具有领地意识的鸟类）身上的分布是聚集性的，这表明虱的丰度存在显著差异。虱的性别比例偏向雌性，且与单个宿主上虱的亚种群大小无关。
