| Popis: | The present work was carried out to evaluate the molluscicidal activity of two pesticides (Chlorpyrifos and Profenophos) against Bulinus truncatus snails. Also, the effect of these pesticides on the survival rate, egg production, growth rate and hermaphrodite gland of B. truncatus snails was carried out. In addition, the effect of these pesticides on the infection of B. truncatus with Schistosoma haematobium as well as on free living stages of S. haematobium (miracidia and cercariae) was studied. Exposure of B. truncatus to these pesticides reduced ( P B. truncatus with S. haematobium miracidia was greatly reduced by exposure to LC 25 of these pesticides and also, the total number of shedding cercariae per snail and the period of cercarial shedding were decreased. The mortality rates of miracidia and cercariae were elevated gradually by increasing the concentration of the testes pesticides. It is concluded that Chlorpyrifos and Profenophos may be helpful in schistosomiasis control as they interfere with the snails’ biology and their production of the infective stage (cercariae). |
