Citrus Mealybug

 

(Planococcus citri), an insect from the Pseudococcinae subfamily, Homoptera order. The body of the female is pinkish, covered with a mealy scale, and 3-4 mm long. The insect is encountered in America, Africa, Asia, and southern Europe; in the USSR, it is found in the Trans-caucasus and Middle Asia. It damages grapevines. The insect propagates predominantly by parthenogenesis, and males are rarely encountered. The larvae and females suck the sap out of plants, greatly weakening them. Berries become covered with the sooty bloom of saprophyte fungi that settle on the secretions of the citrus mealybug, and the fruit becomes unfit for consumption. Defensive measures include treating the vineyards with insecticides and using the predatory beetle Cryptolaemus.
