bean genotypes with and without arcelin over two generations

One of the major stored bean pests is the Mexican bean weevil (MBW) Zabrotes subfasciatus (Boheman). Among control tactics commonly employed against it, the use of resistant cultivars containing arcelin is very interesting. In this work, it was evaluated the development of MBW on eighteen bean genotypes, two of them containing arcelin (Arc-1 and Arc-2) over two generations. Insects were obtained from a stock culture on Bolinha cultivar seeds. Both MBW rearing and experiment were conducted at 27 ºC and 70 % r.h. In a confinement test, fifty seeds of each genotype were infested with five pairs of adult MBW (four replication
