We monitored dispersing coffee berry borer (CBB), Hypothenemus hampei (Ferrari) (Coleoptera: Curculionidae: Scolytinae), with easily-manufactured, alcohol-baited funnel traps and quantified associated berry infestation on 8 coffee farms in 2 regions in Caldas, Colombia. Flight activity and damage to berries was highest in the 2–3 months after the main harvest (Jan through Mar) and was greater in large farms, where insecticides were used, compared with small farms where efficient and frequent cultural control was implemented. The use of traps and attractants will help farmers track CBB populations and localize efforts to control this pest.
