BIOLOGY

On citrus it infests twigs, shoots, leaves, flower buds and fruit. The mealybug colonizes on the host's branches, twigs, shoots, leaves, flower buds and fruits, and feed on roots. From these parts, the mealybug sucks up the plant sap, causing curling and dwarfing of the terminal growth, abortion of flowers, and yellowing of leaves and dropping of fruits (see Sharaf, N.W. & Meyerdirk, D.E. 1987. A review on the biology, ecology and control of Nipaecoccus viridis (Homoptera: Pseudococcidae). Miscellaneous Publications of the Entomological Society of America 66: 1–18).

ECONOMIC AND CONTROL

Nipaecoccus viridis is widerspread throughout the tropics and subtropics, attacking numerous plant species and often causing considerable damage (see Clausen, C.P. 1978. Introduced parasites and predators of arthropod pests and weeds: a world review. Washington, D.C. : United States Department of Agriculture 545 pp.; Sharaf, N.W. & Meyerdirk, D.E. 1987.
