Insects have a wide variety of backgrounds, patterns ecological diversity in mating behavior and structures morphology associated with reproduction. The Hymenoptera are one of four major ordens of Insecta, and probably represents the group most number of species. It has great economic and ecological importance, because understand pollinator species, phytofagous, predators and parasitoids. The order is composed of approximately 80 families, divided into Symphyta e Apocrita. The Apocrita are the most studied, subdivided into two groups: parasite ans Aculeata. The symphyta are more basal and understand about 8 superfamilies. Existing studies show a diversity of morphological characters that can be used for phylogenetic analysis. The inclusion of new characters, combined with the external morphology commonly used, contributing to the various systematic insects that do not yet have a fully accepted phylogeny. In addition studies involving reproductive systems and assist in sperm understanding of reproductive biology, such as different mating strategies and sperm competition. In this thesis, we described the morphology of male reproductive system and sperm in species of Hymenoptera. We utilize techniques of light and electron microscopy. The results show characters that support theinferences systematic, and help the bores of reproductive strategies species. Characters drawn from the morphology of the systems players such as: (1) gross anatomy, (2) number of sperm per cyst; and (3) histology of the reproductive system; indicate interspecific differences capable of grouping other species of higher taxa closely related. From the data obtained, combined with those already described in literature, we aim to provide consistent character that can contribute for phylogenetic studies.
