[Experimental study on the predation of Cionella lubrica Müller by Nesovitrea hammonis Ström].
The predation of C. lubrica by N. hammonis was studied under controlled laboratory conditions. Adult N. hammonis ate mainly prey measuring 2 to 4 mm in height. The predation rate was steady in spite of the increase in number of predators for the same number of prey. Vegetable food was indispensable to N. hammonis' predation. The predation was maximum at 20-25 degrees C. N. hammonis cannot be considered as an agent of biological control against C. lubrica owing to its limited predation.
