The effect of Ambrosia maritima (Damsissa) on the viability of Lymnaea cailliaudi; an experimental study.

ABSTRACT

The present work aimed at studying the effect of Ambrosia maritima (Damsissa) on the viability of Lymnaea snails. Lymnaea snails used in these trials were acclimatized to laboratory conditions before use in the toxicity test. The snails were exposed to various concentrations (100-3000 mg/l) of dry powdered Damsissa, Ambrosia maritima was lethal to Lymnaea snails at concentration of 3000 mg/L after one day and at 100 mg/l after 14 days.
