title: Self-regulation in Bulinus tropicus (Krauss), a snail of helminthological importance.
abstract: Ageing of the culture medium results in the inhibition of oviposition in B. tropicus. Changes in oxygen and ionic levels of the rearing water during the conditioning period do not seem to be responsible for the inhibition and fluctuations in ambient temperature and have no enhancing effect on inhibited oviposition. The results are consistent with the suggestion that some sort of inhibitory compound is released by the snails into the culture water.
