activities against pest and hexane extracts from fruits and leaves of atriplex snail galba truncatula inflata on

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 hexane extracts of the fruits and leaves of atriplex inflata have shown activity against freshwater mollusc molluscide good truncaluta, intermediate host of the parasite fasciola hepatica in tunisia.the hexane extract of the fruits is the lethal dose 50% molluscs are good truncaluta (lc50 = 6.69 mg / l with a confidence interval (4.76; 7,68mg / l (95%), and the hexane extract of leaves is the lethal lc50 = 7,59mg / l with a confidence interval. (20) 9.9 5 mg / l (95%) after 48 hours.using the same lethal doses on molluscs affected by stage of fasciola hepatica is a pesticide activity with a rate of deterioration exceeds 50%, 54,48, 98.92 in larval stages. ru00e9diu00e9s intraru00e9diennes masses and cercariae.the activity against sterols and triterpenes may be related to the content in the hexane extracts of the fruits and leaves of atriplex inflata.
