“…This cosmopolitan insect pest has also been reported as the most important pest of stored beans in Asia (Thakur, 2012), America (Quentin et al, 1991;Silva andCosta, 2016 andBaldin et al, 2017), Africa (Rugumamu, 2014), Europa (Rugumamu, 2014) and Oceania (Daglish et al, 1993). In fact, larvae of A. obtectus enter the common bean seeds from the first instar stage and consume the reserves contained in the cotyledons which causes great losses (up to 30%) (Baldin et al, 2017). Infestation of stored common beans by the bean weevil gives a characteristic pungent odour, making them unfit for consumption and reducing their market value (Paul et al, 2009).…”
