Resumo

Mischocyttarus cerberus stands out as the most investigated species of eusocial paper wasp, in Brazil. While the adult characteristics were relatively well reported in the earlier studies, very meager information was available regarding their immature stages. This study provides a general description of the immature morphology of the brood of M. cerberus, by studying the number of instars and analyzing the degree of influence exerted by some of the environmental factors on the individuals in the immature phases. This work involves a detailed study of 72 wasp colonies from Rio Claro and Ribeirao Preto. Using the larvae drawn from 41 nests, the number of instars was calculated; besides, the degree to which a few environmental factors could affect the immature brood development was assessed in 31 nests. Eggs showed patterns similar in terms of form and size to that of the species described earlier. The two ventral lobes, characteristic of the Mischocyttarus larvae, were fully developed only in the fifth instar. Based on the head measurements, we found that M. cerberus also express five larval instars, which is in agreement with reports published earlier for the most part of social wasps. Besides, larvae took longer than eggs and pupae to develop. From the results of our study, we concluded that M. cerberus showed the typical developmental pattern in the immature stages of the genus.
