Abstract
Laboratory experiments have shown that medium-sized (30-50 mm in shell height) Pomacea sp. snails consumed the egg masses of Biomphalaria glabrata deposited either on glass or on the leaves of Salvinia, and that they also caused a high mortality rate among the newly hatched B. glabrata. When the two species of snail were kept in the same tank, the Pomacea sp. caused a reduction in the B. glabrata egg density in proportion to their relative numbers and the presence of Pomacea sp. prevented colonies of B. glabrata from becoming established. The identity of the Pomacea sp. has not yet been satisfactorily established.
