effect of ambrosia maritima [damissa] 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
