Further information on the Coffee Berry Beetle you find at the Coffee and Conservation site.
“Nearly the entire life cycle of this very tiny beetle takes place inside the coffee ripening coffee cherry. For that reason, pesticides can be largely ineffective against it. Nonetheless, the neurotoxic organochlorine insecticide endosulfan is widely used in coffee farms to try to fight the borers. Not only is this not very effective, it is bad for the environment, and the life history of these beetles enables them to rapidly develop resistance to endosulfan.”
