DESCRIPTION
WHO CAUSES IT?
Planococcus sp. It is a species of mealybug that affects mangoes. These insects have an oval body and are covered in a white waxy secretion, which gives them a cottony appearance. Its life cycle includes several stages: egg, nymph and adult. Adult females, which are immobile, produce a large number of eggs beneath the protective wax they secrete, while males are winged and can move more freely in search of females to breed with.
