Abstract
Several parasitic diseases affecting most human and animal populations have molluscs as intermediate hosts. Diseases such as fascioliasis, which affects cattle, sheep and goats, generating losses for the food industry. This disease has the snail genus Lymnaea, as an intermediate host in its life cycle. To cause great economic losses is a disease of major importance for the field of veterinary medicine. The drugs used for the treatment of this parasitosis reduce morbidity, but not control the transmission. The use of molluscicides agents as a means of controlling the growth and spread of the snails is an efficient strategy and the search for new chemical compounds have been studied. Natural molluscicides are cheap, safe, biodegradable and easily accessible products locally. In this study hydroalcoholic extracts of plants from the Brazilian Cerrado were used, they Neea theifera Oerst., Davilla elliptica, Davilla nitida and Miconia Cabuçu Hoehne, to be tested against snails of the genus Lymnaea and so, we check its possible molluscicides actions. The hydroalcoholic extract of D. elliptica and D. nitida show molluscicidal activity against the species L. columella, and D. elliptica showed more promising results, triggering effects both how and ovicidal molluscicides, in tests.
