Resumo
The density and aggregation patterns of nests of a species of Nasutitermes were determined in an area of 12,750 m2. We found 131 nests in this area, and the distribution pattern was regular, with a density equaling 102.74 nests per hectare. Nest volume was determined from the height and diameter of 105 nests and varied from 1.59 to 192.46 dm3. Of the colonies, 70.5% had a volume below the mean value; 51.4% of these had volumes lower than 9 dm3. Regression between the mean volumes and the distance of the 2 nearest nests was positive and significant (P < 0.001), suggesting competition between colonies.
