TOXICITY OF Salvia officinalis EXTRACTS AGAINST Lymnaea auricularia THE INTERMEDIATE HOST OF FASCIOLIASIS CYCLE DISEASE IN IRAQ

Abstract

The objective of the present study is to determine the acute toxicity of aqueous extracts of Salvia officinalis against the snail Lymnaea auricularia, which is considered as the intermediate snail host of Fascioliasis. About 720 snails were used for the experiments. The LD50, LD100 and Dose-Response relationships of S. officinalis against the snail L. auricularia was calculated. The S. officinalis extracts concentrations were found to be potent against L. auricularia. The results of 96 hr-LD50 and LD100 of S. officinalis extract against the target snail were 6.6±1.1 and 18.4±3.4 g/L respectively. It was observed that the toxicity of different preparation for snails was both time and dose-dependent. The study suggested that the aquatic extract of S. officinalis could be used as a control substance for the target snail.
