The acetone extract of leaf has a great value to control the harmful aquatic snails (Lymnaea
acuminata), and other molluscan pests as shown by the molluscicidal potential (Chauhan & Singh, 2010) against freshwater snail (an intermediate host of liver fluke in cattle and livestock).
columella (Say, 1817) is one of the main snail species, which participates in the life cycle of helminthes, and has been reported as intermediate host by trematodes of the families Fasciolidae, Haematoloechidae, Prosthogonimidae, Plagiorchiidae and Echinostomatidae (Olsen, 1974; Abilio and Watanabe, 1998; Carvalho et al., 2001; Pinheiro et al., 2009).
Similar relationships and exponents have been reported previously for the same species (Randall, 1964) and in other gastropods such as Buccinum undatum (Kideys, 1998), Haliotis fulgens (Farias et al., 2003), Lymnaea
stagnalis (Zonneveld & Kooijman, 1989), Nerita peloronta, N.
Early evidence for conservation of function of ligand-gated receptors emerged from studies of the [GABA.sub.A] receptor [beta] subunit of Lymnaea
stagnalis (Harvey et al., 1989, 1991).

Dentro de los taxones exclusivos y mas comunes que componen las fuentes de agua sin bosques en la zona riberena se encuentran: Heleobia, Aeshnidae, Lymnaea
, Ferrisa y Mesovelia; los cuales tambien son considerados indicadores de contamination por materia organica (Dominguez & Fernandez, 2009).

forskalii, Biomphalaria pfeifferi, Lanistes varicus and Lymnaea
natalensis have been widely reported in different parts of Nigeria to host Schistosome parasites (Okafor, 1990; Okafor and Ngang, 2004, Ayanda, 2009).
