Beans are a major crop in northern Sinaloa. The greatest losses occur during storage and these are caused by diseases insects and pests such brown bean weevil (Acanthoscelides obtectus). To control of these pests are applied malathion, aluminum phosphide and methyl bromide. Due to the high toxicity of these products, in this study, extracts of Bacharis glutinosa, Eucalyptus globules and Melia azedarach, were evaluated for control of brown bean weevil, as an alternative non-polluting and non-toxic to humans. The extracts were obtained with cold water and hot water. The percentage of mortality, emergency and damaged grain were recorded. The results indicate that the extracts used were effective against A. obtectus, with mortality rates of 30 and 50 percent of emergency. The percentages of damaged grain were higher in the control (70 %) compared with treatments applied (< 50%).
