Brazil is a major producer of grains, therefore, it is essential to know sustainable alternatives for pest control in stored grains, which are responsible for severe losses. This review study aimed to gather updated information on the insecticidal activity of essential oils of plants in the control of stored bean weevils. It is a descriptive and bibliographic study, with a qualitative approach. Data collection was carried out using the electronic databases, Google Scholar and the CAPES Journal Portal. The keywords searched were 'Stored bean pests',' Woodworms', 'Pest control', 'Essential oil', 'Acanthoscelides obtectus',' Zabrotes subfasciatus', 'Callosobruchus maculatus',' Fumigation ',' Contact ',' Repellency ',' Insecticidal activity ',' Bean seeds', 'Viability and physiological qualities', these terms being also searched in English in the first ten pages of the article. After the search, exclusion and reading steps of the selected articles, they were organized in tables that show the plant species used, the method of using essential oil on insects and the reference of the work, in increasing chronological order, from 2010 to 2020. In total, 46 articles were selected that met the research criteria, considering the three species of weevils surveyed. The results indicate that the oil of Salvia officinalis was more efficient compared to A. obtectus, and that of Zanthoxylum zanthoxyloides more efficient for fumigation. For Z. subfasciatus, the oils of Baccharis trimera, Cymbopogon winterianus and Pimpinella anisum showed greater efficiency by fumigation, and together with Myrocarpus frondosus, they showed a high repellent effect and ovicidal / larvicidal activity. For C. maculatus, the oil with the greatest potential in lower concentrations is that of the species Mentha piperita. It is concluded that the use of essential oils in integrated bean pest management systems is positive, given the advantages they present. However, it must be verified that the viability of seeds treated with essential oils are not affected, as well as their risks to human and animal health and their influence on crop productivity.
