Lc. Lima et al., BIOMPHALARIA-OCCIDENTALIS PARAENSE, 1981 IN THE STATE OF MINAS-GERAIS, BRAZIL, Memorias do Instituto Oswaldo Cruz, 88(2), 1993, pp. 289-292
A population of Biomphalaria occidentalis was found for the first time
in the State of Minas Gerais. It was probably introduced into the Var
zea das Flores dam, in the municipality of Contagem, the area of study
, during fish stocking in 1985. There is the possibility of ''competit
ive exclusion'' between that species and B. glabrata, previously the o
nly Biomphalaria found in the region. The present geographical distrib
ution of B. occidentalis in Brazil is listed.
