Studies have confirmed molluscicidal activity
of methanolic and chloroformic extracts of 14
plant species of the family Asteraceae collected in
Bolivia and Argentina on Biomphalaria glabrata
d’Orbigny 1835) (Planorbidae) (Bardon et al. 2007).
Hmamouchiu et al. (2000) found molluscicidal
activity in the species Artemisia herba- alba Asso
Asteraceae) on Bulinus truncatus (Audouin 1827)
Bulinidae) in Morocco, and reported the presence
of saponins and flavonoids in this plant. These results
demonstrate the importance of this plant family in
he control of other snail species. The species Bidens
pilosa Linné (Asteraceae) popularly known as hairy beggarticks, is a herbaceous plant with a short annual
cycle (Lorenzi 2000) widely distributed in Brazilian
territory, being used in folk medicine (Adegas et
al. 2003) for antimicrobial (Rojas et al. 2006, Deba
et al. 2008), hepatoprotective ( yuan et al. 2008),
diabetes (Chien et al. 2009) and ulcer (Freise 1933)
antitumoral (Kumari 2009, Kviecinski et al. 2008)
and antioxidant (Krishnaiah et al. 2011).
