larvicidal activities against and in ethyl acetate extracts of leaves and fruits of the snail galba truncatula with atriplex inflata and the larval stages of the parasite, fasciola hepatica

摘要

the molluscides chemicals (such as copper sulfate, copper chloride, etc.) have introduced environmental toxicities and non target organisms. the natural products extracted from plants have shown interesting activities.the ethyl acetate extracts of leaves of atriplex inflata have shown activity against freshwater mollusc molluscide good truncaluta, intermediate host of the parasite fasciola hepatica in tunisia.the ethyl acetate extract of leaves is the lethal dose that killed 50% of the annual good truncaluta shellfish: lc50 = mg / l with a confidence interval (3.63, 95% 7.13) after 48 hours.using the same lethal doses on molluscs affected by stage of fasciola hepatica is a larvicidal activity with a rate of deterioration exceeds 45%, greece; 89.31) in the larval stages, and ru00e9diu00e9s, masses intraru00e9diennes cercariae.the molluscicidal activity could be related to sterols and larvicides and / or triterpenes contained in the ethyl acetate extracts of the fruits and leaves of atriplex inflata.
