The histology and morphology of the reproductive system of females of Rhagoletis conversa (Brèthes) and Rhagoletis nova (Schiner) were studied. These species parasitize wild and cultivated Solanaceae respectively. Adult females of both species were collected in natural populations in the Central Zone of Chile. In order to study the development of ovaries the females collected were sacrificed at different ages. Once obtained, ovaries were preparedfor optical microscopy by using histological and squash standard techniques. Results show that within each one of ovarioles it can be observed follicles arranged in line and showing different stages of maduration. It can be described about 6 follicle stages in the ovarioles studied. Ovaries of both species show a very similar structure. However, females of Rhagoletis nova show an ovipositor wider than R. conversa. The number of ovarioles of R. nova is also higher than in R. conversa.
