The predation of Helobdella triserialis lineata Blanchard, 1849, on eggmasses and specimens of Biomphalaria glabrata Say, 1818 was observed in the laboratory. H. t. lineata was considered art efficient predator on newlyhatched snails, as well as on young and adult specimens with diameter up to 10 millimeters. No predation on eggmasses was observed. Accelerated growth and reduced oviposition were observed in planorbids kept together with the leeches. Some observations were made on the biology of H. t. lineata in experimental conditions, and some measures to control this leech in laboratory colonies of planorbids are suggested.Downloads
