Fontes de resistencia ao bicho-mineiro, Perileucoptera coffeella, em Coffea spp
The species C. stenophylla, C. salvatrix, C. racemosa, C. liberica, C. eugenioides, C. kapakata, C. dewevrei, C. brevipes, C. congensis and C. canephora and cvs Catuaí Vermelho and Mundo Novo of C. arabica were evaluated for resistance to leafminer (Perileucoptera cofeella (Guérin-Meneville, 1842) under lab conditions with artificial infestation of leaf discs. There was no preference of P. coffeella for oviposition on any of the afore mentioned species. According to subjective visual ratings, number of discs with lesions, damaged foliar area and caterpillar comsumption, C. stenophylla, C. salvatrix, C. liberica and C. brevipes can be considered as highly resistant to the insect showing small or no lesions at all. C. kapakata, C. eugenioides, C. racemosa and C. dewevrei can be classified as moderately resistant, C. canephora and C. congensis as susceptible and C. arabica cvs Catuaí and Mundo Novo as very susceptible
