Abstract	Sustainable management of coffee berry borer (Hypothenemus hampei) by systematic pruning of coffee plants. Assessments were performed in 29 coffee plantations in 9 locations in Costa Rica and a field trial was conducted, with the purpose of studying the behavior of the coffee berry borer attack in plots with different pruning systems and validating the differentiated pest control in a row-pruning (every 3 years) system. The assessment of the coffee berry borer, in sites where pruning is performed per plot every 3 years, showed a reduction of 48 percent in the attacks to 1-year branches in relation to the 2-year branches; in plots where row pruning is performed every 4 years, attacks were 52 and 65 percent less in 1 and 2-year branches than in 3-year branches. A similar effect was observed in plots with row pruning every 3 years, where 1-year branches had an average of 56 percent less attack than 2-year branches. In the field trial, after the differentiated application of insecticide, the percentage of fruits with coffee berry borers alive in the 2-year row was of 0.7 percent in both treatments at 90 days after application; whereas in the 1-year row this percentage was 0.7 percent where the insecticide was applied and 1 percent where it was not applied, with no significant differences between treatments. The differentiated control of the
