In: Egyptian journal of biological pest control 2015.v.25(2)Summary: The fish Gambusia affinis (Baird and Girard, 1853) was used under laboratory conditions to evaluate its efficacy as a predator against different stages ofthe snail, Biomphalaria pfeifferi, the intermediate host of human Schistosoma mansoni. Results showed that G. affinis was a voracious predator towards egg-masses and neonate snails with a shell diameter length (SDL) of up to 3.5mm, as well as of adult snails with a SDL greater than 3.5mm. The results showed also that G. affinis had a significant impact on B. pfeifferi snail populations. However, long term studies under natural field conditions are needed to support these results.
