P. marginatus is a polyphagous pest attacking several agricultural, horticultural crops, ornamental plants and weeds of economic value. The papaya mealybug feeds on the sap of the plants by inserting its stylets into the epidermis of the leaf as well as into the fruit and stem. In doing so, it injects a toxic substance into the leaves. The result is chlorosis, plant stunting, leaf defor...
