Laboratory trials for the controlling two snails species namely Biomphlaria aJexandrina and Bulinus truncatus were carried out. Three carbamate compounds (Trimethacarb' Thiodicarb and Methiocarb) and three organophosphorus compounds (Trichlorofon; Phormothion and Phorate) were tested for their molluscicidal activities at intervals with time up to 10 days. On basis of LD₅₀ values after 24 h. or 48 h.exposure, the toxicity order for the carbamates compounds were trimethacarb > thiodicarb > methiocarb and that of organophosphorus compounds was trichlorofon > formothion > phorate. Biomphalaria alexandrina was found to be more sensitive to all the pesticides tested than Bulinus truncates, snails.
