title: Ultrastructural studies on Icerya Seychellarum seychellarum (Westwood) ovaries (Hemipotera: Margarodidae).
abstract: The paired ovaries of the scale insect Icerya seychellarum are composed of Large number of telotrophic ovarioles that are devoid of terminal filaments. Each ovariole is subdivided into an apical tropharium (= trophic chamber) and the vitellarium. The tropharium contains 7 trophocytes, while a single oocyte develops in the vitellarium. The tubular paired accessory glands are also been distinguished. This investigation clearly points out the cytotogical features of the ovaries as well as the accessory glands.
