The knowledge of the behavior of terrestrial molluscs is important for the development of measures of population control of agricultural pests. The aim of this study was to verify the existence of aggregative behavior and site preference for resting on species Allopeas gracilis, Beckianum beckianum, Dysopeas muibum and Leptinaria unilamellata under laboratory conditions. Thirty adult snails of each species were kept grouped (10 snails/group) in sealed plastic terrariums with cotton fabric and elastic, containing humus commercial sterile and moistened and as food, feed for chickens enriched with calcium carbonate. At intervals of 24 hours from the assembly of the experiment until 120 hours were registered numbers: aggregations, aggregates and isolated individuals, and individuals at each site: below disc of food, below disc without food, on the substrate, buried and in the wall of terrarium. It was found that the aggregation is not a characteristic behavior in these species and the favorite place for rest is buried in the substrate. This preference becomes unnecessary the agregation, since both behaviors are used to seal the body area subject to water loss.
