ULTRASTRUCTURAL ASPECTS OF VITELLOGENESIS IN ARCHEGOZETES LONGISETOSUS AOKI, 1965 (ACARI, ORIBATIDA, TRHYPOCHTHONIIDAE)

Ultrastructural aspects of vitellogenesis in Archegozetes longisetosus Aoki, 1965 (Acari, Oribatida, Trhypochthoniidae)

We studied the process of vitellogenesis in the oribatid mite Archegozetes longisetosus using light and electron microscopy.Both vitellogenesis and the formation LED Bulb of the first egg shell occur within the meroi of the ovary, starting after detachment from the medulla and completing with ovulation of the egg into the oviductal lumen at the ova
