Planococcus citri, commonly known as the citrus mealybug, is a species of mealybugs native to Asia. It has been introduced to the rest of the world, including Europe, the Americas, and Oceania, as an agricultural pest. It is associated with citrus, but it attacks a wide range of crop plants, ornamental plants, and wild flora. [1]
Leaves show a characteristic curling, similar to damage caused by viruses. 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.
The blight spreads through an infected tree, invading and colonizing the plant's roots, leaves, and trunk. As of 2020, neither the causal agent nor the spreading mechanism of the disease is known. [2] Research by the Citrus Research and Development Foundation posits the blight is caused by an endogenous plant pararetrovirus (EPRV). [3]
