Abstract

 

Biological control of snail intermediate host of human schistosome parasites has been suggested. In this study, the effect of Indoplanobis exustus a planorbid snail and possible competitor snail of Biomphalaria pfeifferi on the fecundity and growth rate of the later was evaluated. The results showed a significant difference in the growth rates and fecundity of I. exustus and B. pfeifferi. Maintaining the snails together, the fecundity and growth rate of B pfeifferi were greatly reduced. There was direct relationship between fecundity and growth rate. I. exustus could therefore be a control agent of B. pfeifferi under similar prevailing condition.

 

Key words: Indoplanobis exustus, Biomphalaria pfeifferi, Schistosoma mansoni, fecundity, growth rate.
