Bean genotypes containing arcelin (Arc1, Arc2, Arc3 and Arc4) and bean genotypes without this protein (IAC Carioca Aruã, IAC Carioca Pyatã, IAC Carioca Akytã, IAC Maravilha, IAC Una, IAC Bico de Ouro, Porrillo 70 and Goiano Precoce) were evaluated concerning the resistance to the Mexican bean weevil Zabrotes subfasciatus (Boh.), under laboratory conditions. The materials containing arcelin (Arc1, Arc2, Arc3 and Arc4) showed antibiotic effects on the insect, prolonging the development period (egg to adult), reducing male and female weight and longevity, and decreasing fecundity. The cultivars most suitable for the development and reproduction of this insect were Goiano Precoce, IAC Maravilha, Porrillo 70 and IAC Carioca Pyatã.
