Molluscicides of Plant Origin

Characterization of the molluscicidal activity of Bauhinia variegata and Mimusops elengi plant extracts against the fasciola vector lymnaea acuminata

“…Toxicity of crude/ purified preparations of both plants against L. acuminata is in the range of potent molluscicide. Thus, high molluscicidal activity, the LC 50 being less than 100 ppm 8,27 . The 96h LC 50 of crude preparations of both plants are approximately 100 ppm, whereas all organic extracts LC 50 are less than 100 ppm.…”

“…Therefore, there is a need to develop a safe and eco-friendly counterpart of synthetic molluscicides. Molluscicides of plant origin are now gaining special importance because they are more effective, cheaper and safer to non-target organisms and culturally more acceptable 8,27 . The present study describes the molluscicidal activity of Bauhinia variegata (Order: Fabales; Family: Fabaceae) and Mimusops elengi (Order: Ericales; Family: Sapotaceae) against vector snail Lymnaea acuminata.…”

“…Due to more attention on SARS, AIDS, malaria and research in immunological approaches to worm control, a little interest is focused on snail control to minimize the fasciolosis/ schistosomiasis 11 . One of the possible solutions to control fasciolosis is to disrupt the life cycle of Fasciola by killing the vector snail 1,[9][10][11]27,35 . The continuous and indiscriminate use of synthetic molluscicides for the control of vector snails has created a long detrimental effect on the aquatic environment 22 .…”

CHARACTERIZATION OF MOLLUSCICIDAL COMPONENT OF Moringa oleifera LEAF AND Momordica charantia FRUITS AND THEIR MODES OF ACTION IN SNAIL Lymnaea acuminata

“…Fascioliasis caused by Fasciola species is of considerable medical and veterinarian importance 20,26 . It severely affects breeding in cattle, goats, horses, ovines and swine, resulting in serious losses which ultimately affect the economy of live-stock keepers in many countries 12,19 .…”

“…It severely affects breeding in cattle, goats, horses, ovines and swine, resulting in serious losses which ultimately affect the economy of live-stock keepers in many countries 12,19 . The control of the snail population with the help of molluscicide is one of the major tools to reduce the incidence of fascioliasis in cattle as well as in human beings 20,26 . The development of plant molluscicides, as possible substitutes for synthetic molluscicides, is gaining more attention because they are effective, less expensive and eco-friendly 18 .…”
