Development of the muskox lungworm, Umingmakstrongylus pallikuukensis (Protostrongylidae), in gastropods in the Arctic
Development of the muskox protostrongylid lungworm, Umingmakstrongylus pallikuukensis, in its slug intermediate host, Deroceras laeve, was investigated under field conditions in the Arctic. Every 2 weeks, from 19 June to 28 August 1997, groups of 10 experimentally infected slugs were placed in tundr...
