The gerbil flea Nosopsyllus laeviceps (Wagner) (Siphonaptera: Ceratophyllidae) is an important Palaearctic vector of enzootic plague among sylvan and campestral rodents. Laboratory blood-feeding experiments with the subspecies N.l.kuzenkovi (Yagubyants) from Inner Mongolia, China, using three rodent species including the natural host Meriones unguiculatus (Milne-Edwards), demonstrated a positive relationship between per cent feeding and time allowed for feeding, particularly for female fleas. Also the bloodmeal size was proportional to sucking time and was significantly greater in females, which are larger, than in males. However, on all four strains of host tested, there was no significant correlation between the feeding success rate of the fleas and the amount of blood they imbibed. Fleas fed better on active compared to confined M.unguiculatus. These findings agree with studies of other flea species.
长须山蚤（Nosopsyllus laeviceps (Wagner)）（蚤目：角叶蚤科）是古北区森林和田野啮齿动物中腺鼠疫的重要传播媒介。使用包括天然宿主长爪沙鼠（Meriones unguiculatus (Milne-Edwards)）在内的三种啮齿动物对来自中国内蒙古的长须山蚤库氏亚种（N.l.kuzenkovi (Yagubyants)）进行的实验室吸血实验表明，吸血百分比与吸血时间呈正相关，尤其是雌蚤。此外，血餐量与吸血时间成正比，且体型较大的雌蚤吸血量显著高于雄蚤。然而，在所有测试的四种宿主菌株上，蚤的吸血成功率与吸血量之间均无显著相关性。与圈养的长爪沙鼠相比，蚤在活动的长爪沙鼠身上吸血效果更好。这些发现与对其他蚤类物种的研究结果一致。
