The present study investigated myrtle rust and gall wasp from non-commercial eucalypt taxa with potential to hybridization. We selected 38 genotypes from 18 species of Corymbia and Eucalyptus (Symphyomyrtus) genus. Two rust inoculations were evaluated using inoculums from rose apple and eucalypt, and natural gall occurrence in a high pest infestation condition. Corymbia was more susceptible to rust than Eucalyptus genus, and it was observed severity variation due to the sources of rust inoculum. Species that belong to Exsertaria and Transversaria (Latoangulatae) sections were more susceptible to gall wasp, and Corymbia species showed no development of gall.
