RESUMO

Aspects of the social biology of the Neotropical wasp Mischocyttarus consimilis Zikán, 1949 (Hymenoptera, Vespidae) - This work had for objective to study aspects social biology of the Neotropical wasp Mischocyttarus consimilis, of the which specifically understand: 1. colonial phenology; 2. architectonic model of nests and pattern of construction of nests; 3. colonial productivity; 4. foundation pattern and colonial success; 5. duration of the immature stage and 6. duration of the colonial stage and flotations in the offspring density and adults. The observations were led at the own nidification places. The nests of M. consimilis presented an only discovered comb that is arrested to the substratum by an only petiole. Architectural data of the nest showed a correlation significantly positive between the size of the comb and diameter of the petiole, and still between the length and width of the cells. The nidification happened in substrata of plan horizontal, vertical and tilted, without seemingly to exist any preference for either specific orientation. The colonies produced 72.85 cells and 40.71 adults on average. The medium frequency of productive cells was of 33.27% and the maximum number of maximal number of cell utilization was on average 2.07 times. The medium duration of the all immature stage was of 69.73 days, and the stage of egg, larva and pupa had medium duration of 14.86, 36.03 and 18.84 days, respectively. The duration of each immature stage was significantly smaller in the hot-humid station, and the stage of larva and pupa were only smaller during the colonial stage of pre-emergence. The foundation periodicity and abandonments of colonies in this species followed a pattern asynchrony. Most of the abandonments happened for natural causes and they were more frequent in the preemergence colonial stage. The through colonial cycle had medium duration of eight months, however, some colonies had duration above one year. The colonies were found rather in human constructions and in sheltered places, without direct incidence of solar light and water of the rain. The foundations of colonies happened so much for haplometrosis as for pleometrosis, being the first the predominant pattern. In the foundations pleometrotics the foundress number varied among two and six
