N2 - Whitefly (Bemisia tabaci (Genn.) is an important pest in pepper (Capsicum spp.) production, not only because infestations lower the quality of the fruits but also because whiteflies transfer viruses. Therefore, resistant varieties are urgently needed. In this research, we searched for Capsicum accessions resistant to B. tabaci MEAM1. Forty pepper accessions underwent screening through a no-choice clip cage assay, evaluating adult survival and oviposition rate of female adult whiteflies. Accessions with low survival were validated by assessing whitefly population buildup in a whole plant assay. Lastly, whitefly nymphal survival and development were scored for the three most resistant accessions. Accession Zuchtmaterial Nr.1 demonstrated the ability to reduce adult survival and reproduction and halted whitefly development at the egg and first nymphal stage, thus repressing population buildup. Additionally, we observed that glandular trichomes type VI were found in the resistant accessions and exhibited a negative correlation with adult survival, oviposition rate, and the number of all stages of whiteflies. Thus, we conclude that Zuchtmaterial Nr. 1 could serve as a useful source for whitefly resistance, with a possible role of type VI glandular trichomes as a resistance mechanism.
