The situation was disturbed during the early 1950s by the use of persistent chlorinated hydrocarbon insecticides to control other pests on coffee, but was re-established when non-persistent insecticides replaced the chlorinated hydrocarbons. In 1959, it was estimated that some £10 million had been saved against an outlay of a total expenditure of not more that £30,000 (Greathead, 1971 and references therein). This programme emphasized the need for accurate identification of the pest and the need to look in its native distribution area for effective natural enemies.
