The Pallas's squirrel (Callosciurus erythraeus) has invaded fragmented woodlands in urban areas of Kanagawa Prefecture, where frequent human contact occurs. We examined 538 squirrels in Hayama-machi, Kanagawa Prefecture, for ectoparasite infestations. A total of 1,164 lice, 877 fleas, and 231 ticks were retrieved from 297 (55.2%), 338 (62.8%), and 135 (25.1%) squirrels, respectively. The identified ectoparasite species were Neohaematopinus callosciuri, Ceratophyllus anisus, Haemaphysalis flava, Haemaphysalis hystricis, and Ixodes turdus. The prevalence of N. callosciuri and C. anisus was significantly higher in adult males (N. callosciuri 63.6%, C. anisus 70.4%) than that in adult females (N. callosciuri 36.1%, C. anisus 49.0%; P<0.0001). Such information on the dynamics of host-ectoparasite relations is crucial for evaluating the risk to public health.
赤腹松鼠（Callosciurus erythraeus）已侵入神奈川县城市地区的碎片化林地，这些地方人类接触频繁。我们检查了神奈川县叶山町的538只松鼠是否感染体外寄生虫。分别从297只（55.2%）、338只（62.8%）和135只（25.1%）松鼠身上检出了1164只虱子、877只跳蚤和231只蜱虫。鉴定出的体外寄生虫种类有赤腹松鼠新血虱（Neohaematopinus callosciuri）、不等角叶蚤（Ceratophyllus anisus）、黄褐血蜱（Haemaphysalis flava）、猬形血蜱（Haemaphysalis hystricis）和乌鸫硬蜱（Ixodes turdus）。成年雄性松鼠中赤腹松鼠新血虱和不等角叶蚤的感染率（赤腹松鼠新血虱63.6%，不等角叶蚤70.4%）显著高于成年雌性松鼠（赤腹松鼠新血虱36.1%，不等角叶蚤49.0%；P<0.0001）。此类宿主 - 体外寄生虫关系动态的信息对于评估公共卫生风险至关重要。
