Among the factors that limit mango production, mites are one of the most important due to the association they have with pathogens that damage the crop. The objectives of this work were to identify the mites and pathogens associated with the floral malformation of the mango, as well as the mites in foliage in an orchard of Gabriel Zamora, Michoacán. Samples of foliage and malformations of mango inflorescence were taken in an orchard in the municipality of Gabriel Zamora from November 2015 to January 2016, which were taken to the laboratory to dissect the plant matter and assemble the mite species collected; in the same way, the mites associated with the malformation were sown in PDA medium and the fungal colonies that germinated in the medium were separated, to finally identify them with taxonomic keys. Aceria mangiferae and Fusarium mexicanum were identified as the mite and fungus associated with the malformation of mango inflorescence, as well as Oligonychus mangiferus as the species of mite associated with foliage in Gabriel Zamora, Michoacán.

Keywords : Michoacán; mite-pathogen determination; witch’s broom.
