Abstract
The development of F. hepatica was histologically analyzed in L. truncatula, L. glabra and L. palustris infested at hatching with a single miracidium. The development of the redial generations of Fasciola is not affected by the species of snail host but depends on growth of the snail. In snails of size within 2 mm (considerated at the day 49 of infestation to 20.degree. C), the rediae show a delay of maturity compared with rediae observed in snails of higher sizes. The distribution of redia 1 of generation 1 should have an influence on growth of the snail host.
