Echinostomatid larval stages in Lymnaea viatrix (Gastropoda: Pulmonata) from southwest Patagonia, Argentina
The partial life cycle of an echinostomatid found in Lymnaea viatrix from Patagonia, Argentina, was experimentally clarified. Emerging cercariae were exposed to laboratory-reared specimens of Biomphalaria sp. Metacercariae obtained from both naturally and experimentally infected snails were force-fe...
