Title: The osphradium is involved in the control of egg-laying in the pond snail<i>Lymnaea stagnalis</i>
Abstract: Summary Ablation of the osphradium (a peripheral putative chemo-sensory organ) in Lymnaea stagnalis resulted in significant increase of egg-laying activity as compared with control animals (observed for 50 days). Cutting the osphradial nerve increased egg-laying to a lesser degree and only for the first 15–20 days. Water changes in the aquaria had a similar stimulating effect on egg-laying activity in both osphradium-deprived and control snails. Permanent aeration of the aquaria abolished this effect. Possible mechanisms of tonic inhibitory action of the osphradium on egg-laying are discussed.
