Abstract
The giant looper (Ascotis selenaria reciprocaria Walk.), which was first recorded on Arabica coffee in Kenya in 1961 by Wheatley (1963), has become firmly established as a pest of estate-grown coffee in all coffee growing districts east of the Rift Valley. It has also since been recorded (Bigger, 1966) on estate-grown coffee in northern Tanzania. Although this pest feeds primarily on young leaves it also eats flower buds and can cause direct crop loss by eating young cherries. Damage to suckers , which are brought up from the stem base to start a new growth cycle in multiple-stem coffee, may constitute another form of indirect loss by delaying the start of the new cropping cycle.
