The Role of Follicular Cells During Vitellogenesis of Oocytes in The Dragonfly Pantala Flavescens (Fabricius) (Libellulidae: Anisoptera)

The last two larval instars and adults of Pantala flavescens were selected. The ovaries from these instars and adults were dissected out to process for histological preparations. At the beginning of vitellogenesis, the basal oocyte in the ovary increased in size and the epithelial cells become columnar with intercellular spaces. The follicular cells became secretory and the oocyte developed inner vitelline membrane and outer chorion. The present study clearly evidenced for intercellular pathway of vitelline precursors inside the oocytes.
