citrus mealybug

The citrus mealybug (Planococcus citri) is a small, sap-sucking insect found worldwide that primarily infests citrus trees and ornamental plants. These insects are characterized by a white, powdery coating that resembles cornmeal, giving them their name. Mature females are typically oval-shaped and about 1 cm long, often found clustered on the undersides of leaves.1

Mealybugs are related to other common plant pests such as scales, whiteflies, and aphids. While they can be destructive to citrus crops, effective control methods include biological control, insecticidal soaps, horticultural oils, and traditional insecticides. Eradication programs, like those for citrus canker, have historically involved measures such as spraying infected trees with oil and burning them.12
