The resistance of six cultivars and four isogenic lines of bean, Phaseolus vulgaris, to Zabrotes subfasciatus (Boh.), using choice and no-choice tests were evaluated. The lines with arcelin presented antibiosis, being arcelin-1 the most resistant one. This line increased the egg-adult period in 11.9 days and reduced the percentage of adult emergence in 86.9% when compared to the mean values of the cultivars without arcelin. None of the six cultivars showed antibiosis, but the egg laying in the choice test was lowest for cv. Safira, IPA-7, São José, and HF-465-63-1.
