Abstract
This document provides an in-depth profile of the cottony cushion scale, Icerya purchasi Maskell, detailing its introduction, distribution, description, and economic impact. Originating from Australia, this pest spread to California and later Florida, causing significant damage to citrus groves. Biological control methods, including the introduction of the vedalia beetle, have been implemented to manage its population. The cottony cushion scale is distinguished by its bright orange-red body and large, fluted egg sac. It primarily affects citrus and pittosporum plants, leading to decreased tree vitality, fruit drop, and defoliation.
