[Lethal activity of benzamido-2 nitro-5 thiazole and its derivatives against Lymnaea peregra ovata Müller (Mollusca: Pulmonata) and Gammarus pulex pulex L. (Crustacea: Amphipoda)].
The toxicity of benzamido-2-nitro-5-thiazole (BNT) and 3 derivatives was studied on Lymnaea peregra ovata and Gammarus pulex pulex. These results were compared with the toxicity obtained by application of a basic product, niclosamide. The evaluation of LC50 (50% lethality concentration) was studied to evaluate the toxicity of each product after 4 different assay periods: 24, 48, 72 and 96 h. The compounds had a high toxicity against snails. Molluscicidal effect was higher than the lethal activity against Crustacea. The ortho substitution decreased the toxicity of products compared with BNT.
