Heavily infested plants have shortened internodes leading to resetting or a "bunchy top" appearance. A heavy, black, sooty mold may develop on an infested plant's leaves and stems as a result of the mealybug's heavy honey-dew secretions. When fruits are infested, they can be entirely covered with the white waxy coating of the mealybug.
Mealybug females feed on plant sap, normally in roots or other crevices, and in a few cases the bottoms of stored fruit. They attach themselves to the plant and secrete a powdery wax layer (hence the name "mealy" bug) used for protection while they suck the plant juices. The males are short-lived, as they do not feed at all as adults and only ...

The mealybug is most common in spring and summer, its populations fluctuating according to temperature and available host plants. Peak abundance is noted in early summer in Florida citrus. Mealybugs infesting plants in the constant conditions of greenhouses have stable, steadily reproducing populations all year.
The plant is susceptible to mealy bug infection, which can result in growth retardation and also cause high fungal contaminations in in vitro studies. To reduce the mealy bug's infection, 90% ethanol can be directly applied to the infestations using paint brushes.
The adult female cotton mealybug lays several hundred eggs in an ovisac. On hatching, the nymphs crawl away, dispersing to other parts of the plant. In dry conditions, they move to the roots and the lower leaves and stems, however in wetter conditions they prefer the upper parts of the plant.
