Ghosh, A.B., & Ghose, S.K. 2000 Effect of Some Ecological Factors on the Nymphal Development of Mealybug, Nipaecoccus viridis (Newstead) Pseudococcidae: Hemiptera).. Environment & Ecology 18(4): 922-925.

Notes: The developmental periods of all female nymphs and up to second male nymphs of the mealybug, Nipaecoccus viridis (Newstead), were prolonged when reared individually. The development of female and male nymphs were also delayed at constant relative humidity of 40, 60 and 80%. Third nymphal females at 80% and fourth nymphal males at 60 and 80% moulted 5 days later than at other humidity levels. The constant exposure to light had induced moulting earlier than darkness in second nymphal females only. The presence of attending ant, Camponotus oblongus Sm. accelerated the development and moulting in first instar nymph.
