Pineapple scale
Diaspis bromeliae

Pineapple Scale (diaspis bromeliae) adult female is 1.5-2.5 mm diameter, circular and slightly convex. Heavy infestations cover the plant in a light grey, scurfy coating. The most obvious damage is the formation of chlorotic spots where the scales feed. Heavily infested plants may become weak and stunted, with die back of the foliage; they produce undersized, pinched-looking fruit.
