ABSTRACT The parasitoid Diachasmimorpha longicaudata is an important control agent for several species of fruit flies.Research on the characteristics of the reproductive system and reproductive biology of this toys parasitoid can be valuable for studies in taxonomy and phylogeny of insects of the order Hymenoptera.In this study we analyzed the histology and histochemistry of the male reproductive system of D.

longicaudata.In this species the male reproductive system consists of a pair of testes, two accessory glands, and an ejaculatory educational toys duct.Each testicle consists of only one follicle.

The testicular follicles are filled with cysts in different stages of spermatogenesis.Histochemical analyses detected proteins and carbohydrates in the cytoplasm of secretory cells and in the lumen of accessory glands.The morphology of the male reproductive system of D.

longicaudata differs in some respects from other species of Hymenoptera.
