Two populations of Apodemus sylvaticus, one in deciduous woodland and another in coniferous forest in Co. Down, Northern Ireland, were trapped at monthly intervals over 33 months. The dynamics, reproduction and age structure of the mouse populations differed between years with over a 40 fold range of population size. Nine species of helminths were recovered from the alimentary tract and associated organs of the mice. The prevalence and mean worm burden of the cestodes, Catenotaenia lobata, Hymenolepis hibernia and Taenia taeniaeformis varied erratically. The trematodes, Corrigia vitta and to a lesser degree Brachylaima recurva, had seasonal changes in abundance. The nematodes Capillaria murissylvatici and Nematospiroides dubius had strongly seasonal cycles of abundance associated with the onset of host reproduction. Trichuris muris was the rarest helminth. Despite protracted periods of absence this species maintained a seasonal increase in mean worm burden in late winter. The nematode, Syphacia stroma, had a weakly seasonal pattern of dynamics. The bases of these cyclical and non-cyclical dynamics of the helminths of A. sylvaticus are discussed.
在北爱尔兰唐郡，对林地姬鼠的两个种群进行了为期33个月的逐月诱捕，其中一个种群位于落叶林地，另一个位于针叶林。不同年份小鼠种群的动态、繁殖和年龄结构有所不同，种群大小范围超过40倍。从小鼠的消化道及相关器官中检出了9种蠕虫。带状链尾绦虫、爱尔兰膜壳绦虫和鼠带绦虫的感染率和平均虫负荷变化无常。曲带斜睾吸虫以及程度较轻的弯睾短体吸虫，其丰度存在季节性变化。鼠毛细首线虫和双瓣旋毛虫的丰度具有强烈的季节性周期，与宿主繁殖的开始相关。鼠鞭虫是最罕见的蠕虫。尽管有很长一段时间未出现，但该物种在冬末平均虫负荷仍呈季节性增加。线虫斯氏管状线虫的动态变化呈弱季节性模式。本文讨论了林地姬鼠蠕虫这些周期性和非周期性动态变化的基础。
