The role of chewing lice (Phthiraptera: Philopteridae) as intermediate hosts in the transmission of Hymenolepis microps (Cestoda: Cyclophyllidea) from the willow ptarmigan Lagopus lagopus (Aves: Tetraonidae)
Abstract The cestode Hymenolepis microps is an intestinal parasite of tetraonid birds, including the willow ptarmigan ( Lagopus lagopus ). This parasite is able to maintain a high prevalence and intensity throughout the year, even in a subarctic environment in bird populations with relatively low ho...
