The Coffee berry borer (CBB) is the most important pest in the coffee plantings. Losses are due to quality and quantity reductions. In most plantings, CBB is controlled using insecticides. Alternative management strategies are strongly demanded due to increasing production and demand for organic products. This paper revises the use of traps for CBB management. Color and trap designs, attractants and release rates are the factors directly related to trap efficiency. Methanol and ethanol mixture is used as attractant. Interactions among these factors in the CBB attraction are reported. Environment conditions under which the coffee plantings are conducted influence trap captures. These aspects may explain some differences in results for different studies. Conflicting results are also found in relation to traps efficiency when they are used as a unique control strategy in the field. Additional research may be encouraged to understand more deeply the interactions between the CBB and coffee plant. In the same way, we must study the interactions of the several intrinsic factors of the traps and the environment. The use of the trap, associated with other strategies to reduce pest population, is a recommended strategy for CBB management.
