Problem

Female Coffee berry borers bore holes into mature and immature coffee berries while still on the tree. Eggs are deposited and when they hatch, they eat into the bean.

Description

Coffee berry borers bore into the scar at the blossom end of the coffee fruit. The borer only attacks the fruit, not the branches or the leaves of the tree.  Coffee beans may sustain further attack by opportunistic fungal or bacterial infection as well as other insects taking advantage of the hole in the fruit.
