similaris maintained under different population densities were analyzed, focusing on the oviposition, hatchability and galactogen content in these snails.
The galactogen was extracted according to Pinheiro and Gomes (1994) and determined by the 3,5 DNS technique (Sumner, 1924).
(1996), through a chromatographic study, showed that the galactogen of the albumen gland of B.
However, this is the first time that the galactogen content is used to evaluate the reproductive biology of B.
