[Mechanism of distribution of Strongyloidea larvae among ungulate animals at pasture]. / O makhanizme rasseleniia lichinok strongiliat kopytnykh na pastbishche.

The problem of dissimilation of larvae of strongylates of ruminants in pasture biocoenosis is discussed. A new form of their migration in horizontal direction on the basis of negative geotaxis is suggested. As a result of alternation of vertical migration of larvae on the tilting leaves of the grass and their subsequent washing off with rain or dew down on the ground proceeds their distribution on the pasture. The description of corresponding experiments is given.
