Nipaecoccus viridis (Newstead, 1894) - (spherical mealybug)
This mealybug is widely distributed in tropical and subtropical countries of Asia, Africa and the Australia/Pacific region. Since 2009, it has been also recorded from North America, and has subsequently spread to other parts of the continent. It is of quarantine concern in Europe. The mealybug is polyphagous and among other crops, it attacks the shoots and fruit pedicles of citrus, causing early fruit drop, and yield losses of up to 50%. Further, sooty mould is produced through the excretion of large amounts of honeydew (Diepenbrock & Ahmed, 2020). Chemical control is often not effective because it kills natural enemies and mealybugs are often protected in hidden locations.
The adult female of N. viridis has an oval body, approximately 4 x 3 mm and a dark colour, ranging from black to purple to blue green. However, it is usually covered by thick white, or pale yellow wax filaments. When crushed, it reveals a dark purple hemolymph.
