A range of plant sucking
bug species cause problems with coffee production. Most of these originate
from East and Central Africa. CABI Bioscience has assisted several
countries to implement biological control of these pests though research
in East Africa to explore, identify, rear and ship biological control
agents to affected countries. These have been sent to several countries
in the Pacific and Asia.
Sean Murphy has a decade of experience of working on the control of
coffee scales throughout the world, most notably in East Africa, where
he has worked on the ecology and biological control of scale insect (Homoptera)
pests. Dr. Murphy and Dr. Moses Kairo also have several years of experience
in evaluating the effects of insecticides upon natural enemies in coffee
systems in situations where pests have been induced by the injudicious
use of chemicals.
