      The alcohol-based volatile compounds have been used as attractive in the management of coffee berry borer (CBB), Hypothenemus hampei (Ferrari, 1867) (Coleoptera: Curculionidae: Scolytinae). However, some of these compounds are highly toxic to humans and the environment, as is the case with methanol. Then, the objective of this study was to verify the attractiveness of semiochemicals mixed with ethanol to CBB in olfactometer and to determine a possible substitute for methanol in the mixture with ethanol in the capture of the CBB in the field. The laboratory tests were performed on an olfactometer, with the compounds: cinnamaldehyde; eugenol; citral; ethyl acetate; acetic acid; geraniol; isopropyl alcohol; butyl alcohol and the methanol. The mixtures that stood out most in the olfactometer tests were used in the field experiment. These compounds were used in transparent traps made with 2 L PET bottles, with rectangular side opening (20 x 15 cm) to capture of CBB. The ethanol: cinnamaldehyde and ethanol: methanol mixtures attracted a greater number of CBB in the olfactometer tests. The ethanol: methanol mixture provided a better efficiency in the capture of CBB in all periods of field evaluations.
