Résumé

The influence of non-target freshwater snails [Melanoides tuberculata and planorbis planorbis] on the capacity of Fas-ciola egg production F. gigantica miracidia to infect Lymnaea natalensis and their affect on mortality and growth rates showed that the snails exhibited a competitive ability against L. natalen-sis The mortality rate existed in mixed cultures with snails was greatly increased, and increased with increase of snails number. The egg production and growth rate were negatively affected by the presence of M. tuberculata and p. planorbis which was more pronounced when snails were at higher ratio 1L:10D.Also, the snails showed significant degree of reduction in infection rate of L. natalensis with F.gigantica miracidia.
