Ultrastructural organization of spermatocysts in the testes of Aedes aegypti (Diptera: Culicidae)
Autor(es): Wandall A
Resumo: The spermatocysts in pupae and adult males of Aedes aegypti were analyzed with an electron microscope. The number of premeiotic cysts was high in both pupae and 1st-day males but low in 3-6-day-old males; the number of meiotic cysts was higher in pupae than in adult males. In old males the morphology of spermatogonia and spermatocytes had changed in a way that suggested that degenerative processes had begun. Two meiotic cysts containing 126 and 127 cells were reconstructed, and the bridge connections between the cells were analyzed. Bridge distribution among the cells did not follow a predictable pattern; in this respect the spermatocytes resemble the follicle cells covering the egg chamber, but not the cystocytes themselves.
