Coccid pests of coffee

Abstract

The commercial development of coffee cultivation in this territory is still in its early stages, and the areas are widely scattered.

There are two groups of the Coccidae, commonly known as “ mealy bugs ” and “ scale insects ”. The former are soft-bodied insects covered with a waxy coat and capable of movement; the latter, once they begin to feed, become attached to the plant and develop a tough scaly covering. Both groups obtain their nourishment by puncturing the bark and sucking the sap. When plentiful, they take a considerable amount of sustenance from the plant.
