- Abstract
Effect of the lupine seed extract (Lupinustermis (Forsk) was studied on the aquatic snail Biomphalaria alexandrina (Ehrenberg), the intermediate hosts of Schistosoma mansoni Sambon, Bulinus truncatus (Aouduin), the intermediate hosts of Schistosoma heamatobium Bilharz and the terrestrial snails Eobania vermiculata (Müller) and Monacha obstructa (Ferussac), the most abundant snails in Egypt. Results indicated that ethanolic lupine seed extract had a toxic effect on B. alexandrina, where it caused 100% mortality of the snails exposed to 250 ppm (0.025%) after 60 hours, 500 ppm (0.05%) after 48 hours, 1000 ppm (0.1%) within 36 hours and 1250 ppm (0.12 5%) within 24 hours. Percentage mortality increased with the increase of the concentration. LT50 and LT90 values decreased gradually as the concentration increased. Similar effect was recorded on B. truncatus but with higher concentrations, since 100% mortality occurred at 1250 and 1500 ppm after 48 and 24 hours, respectively. The ethanolic extract showed only repellent and/or anti-feeding effects on the terrestrial snails at the concentrations 1-10%.
