S. O.  aA comprehensive screening of sources of resistance in common bean genotypes to Zabrotes subfasciatus (ColeopterabChrysomelidae: Bruchinae).h[electronic resource]  c2025  aThe initial step in the successful implementation of a breeding program aimed at obtaining bruchid resistant beans lines is the identification of sources of resistance within a diverse germplasm. Here, a total of ninety two (92) Brazilian common bean genotypes were screened to identify promising sources of resistance to Zabrotes subfasciatus (Boheman) (Coleoptera: Chrysomelidae: Bruchinae), the primary insect pest of stored beans. The cultivars BRS Ametista and BRS Esplendor, as well as the bean lineages CHP 01-182-12-Uirapuru ?? Campeiro and CHP 04-241A-212-Guapo B. ?? Uirapuru exhibited the lowest oviposition rates. The genotypes BRS Ametista, CHP 01-182-12-Uirapuru ?? Campeiro and BRS Esplendor also showed the lowest average of adult emergence evidenced by the F1 progeny. In contrast, genotypes BRS Ametista, CHP 05-282-04-Campeiro ?? Agudo, TB-17-02, CHC 01-167-1-03, IPR Uirapuru, CHIR 14, IPR Campos Gerais, CHIC 61-Carioc??o, IAC Imperador, Arcelin 1, FAP-F3-2-SEL-IAC, CAV 17 EFM008, SCS 205-Riqueza, LP 13-634-preto, IAC Harmonia and Linhagem 110-IAC exhibited the lowest percentage of larval-pupal viability. Conversely, genotypes Arcelin 3, Arcelin 1, CHIN 19, CHV 05-268-02, LP 13-84-Carioca, CNFRs-15558-Rosinha, IPR Campos Gerais, CHC 01-175-1-Campeiro ?? IAC Tibat??, BRS Not??vel, IPR Uirapuru, BRS Estilo, IPR Quero-Quero, CAV 17 EFM0006, CHP 04-241A-212-Guapo B. ?? Uirapuru, BRS Esplendor, and CHP 01-182-12-Uirapuru ?? Campeiro were observed to significantly prolong the developmental time (cycle) of Z. subfasciatus, indicating the expression of antixenosis and/or antibiosis type resistance. Thus, these genotypes are promising sources of resistance to Z. subfasciatus, and further studies are recommended to elucidate the underlying mechanisms and genes involved.  aAntibiosis  aAntixenosis  aMexican bean weevil  aPhaseolus vulgaris1 aCABRAL, I.
