THE LOCAL DIFFERENCE OF THE RESISTANCE OF ONCOMELANIA NOSOPHORA, THE VECTOR SNAIL OF SCHISTOSOMA JAPONICUM, TO THE DESICCATION

Abstract

In the previous paper, one of the authors and a coworker (Komiya et al., 1958) reported results of an experimental study with Oncomelania snails on the resistance to dryness. Regarding this problem, the authors became aware of the existence of local difference in the resistance of snails to desiccation. The following is results of experiments concerning this problem.
