Maity, A., & Ghosh, A.B. 2004 Morphology of various instars of the mealybug, Icerya aegyptiaca (Douglas) (Margarodidae: Hemiptera).. Environment & Ecology 22(1): 7-12.

Notes: Descriptions and illustrations are given on different instars of the mealybug, I. aegyptiaca. The first and second instar nymphs possess six segmented antennae; the former has large setae on apical segment of antenna and no waxy tassel but the later has waxy tassels along body margin. The third instar nymphs have 9, rarely 8, segmented antennae and multilocular disc pore with bilocular centre on dorsum of head and thorax. The adult females possess 11, rarely 10, segmented antennae, vulva and ovisac band pore. Disc pores with trilocular centre surrounded by kidney-shaped multiple loculi produce waxy tassels with the help of marginal setae but pores surrounded by small multiple loculi produce ovisac. All other dermal pores secrete waxy dusts. No male has been recorded. Pedilanthus tithymaloides (Euphorbiaceae) and Vernonia cinerea (Compositae) have been recorded as its new hosts.
