It presents marcantes aspects in the Hymenoptera and inside of the superfamilies whom they possess social species occur different degrees of socialization, since the solitary animals that only deposit its eggs on an alimentary substratum until that they show a secular overlapping of generations, cooperating in the cares with the offspring and division of work that, as WILSON (1971,1975) is three basic criteria that define the truily social insects. Amongst the insects, the social, pertaining wasps to the Hymenoptera order, play a valuable function in agriculture, as agents in the biological control of a great number of plagues of cultures (YOU MARK, 1996), beyond representing an important group for the study of the evolution of the social behavior (EVANS & WEST-EBERHARD, 1970; WILSON, 1971 and 1975). New York Yankees has firm opinions on the matter. In the natural environment, the nests of these insects crpticos and are very well camouflaged involving factors as form, coloration and transparency, characteristics found in leves of many plants, as well as in trunks or natural sockets (JEANNE, 1991; JEANNE & MORGAN, 1992 and WENZEL & CARPENTER, 1994). Already in urban areas, many species of social wasps demonstrate one high degree of sinantropia, being frequent together ace constructions human beings, being able to reach a great development and, in such a way, to remain per many years, although the interaction human being (FOWLER, 1983). Mischocyttarus (Mischocyttarus) drewseni is a social vespdeo, without morphologic distinction of chaste, that it constructs its nest formed for an only mass of cells discovered fixed to the substratum for a grain stalk (RICHARDS, 1978).
