Zabrotes subfasciatus (Boheman, 1833) (Coleoptera: Bruchidae) is considered the main stored bean pest. The most widely used method of control is the use of insecticides. However, other control methods may be applied, such as plant resistance. Aiming to find alternative strategies to its control, this study evaluated the types of resistance in 12 bean genotypes. The experiment was carried out at the Laboratory of Plant Resistance to Insects of the Department of Phytopathology of the FCAV/UNESP, Jaboticabal/SP, from March to November 2009. Oviposition non-preference (free choice and no-choice) tests and the no-choice test for feeding were carried out. The results demonstrated that: the genotypes Dor 391, Dor 476, IAPAR-MD 806, and Raz 59 showed non-preference to oviposition by Z. subfasciatus, in the free-choice test; in the no-choice test, all genotypes were equally oviposited by the insect; in the free-choice chance test, males and females were equally attracted by all tested genotypes and Raz 56, Arc 2, Raz 55, Raz 49, and Raz 59 showed non-preference to feeding and/or antibiosis.
