The present study was undertaken to investigate the lethal activity of chlorophyllin against different developmental stages of Biomphalaria alexandrina snails and Schistosoma mansoni aquatic larvae under laboratory conditions. In all experiments, the studied organisms were incubated in different chlorophyllin concentrations in the dark, and then exposed to sunlight to stimulate the lethal photosensitizing action of chlorophyllin. Snails lethal concentrations for six hours of sunlight exposure were as follows: LC90 (131.86 ppm), LC50 (82.68 ppm), LC25 (56.93 ppm) and LC10 (33.76 ppm). The lethal action of chlorophyllin is affected by several factors including: light source, duration of sunlight exposure, the developmental stage of the snails and the presence of infection. On the cellular level, histological sections revealed marked destruction of certain tissues with loss of their landmarks. Chlorophyllin also had a profound lethal effect on the larval stages of Schistosoma mansoni. So, chlorophyllin is a promising substance of plant origin that could be used in snail control programs.
