Abstract : In this work is presented the distribution on mango 'Haden' trees (branches, leaves, flowers and fruits) of endophytic fungi during a production cycle. The diagnosis was made at four mango 'Haden' commercial orchards located at eastern region of Venezuela. The fungi were recorded employing triple sterilisation specific method for endophytes fungi. All the isolated fungi are recognized pathogens of mango. The following species were identified Fusarium decemcellulare, Lasiodiplodia theobromae, Pestalotiopsis sp., Cladosporium sp. and Colletotrichum gloeosporioides.. The distribution of L. theobromae and Cladosporium sp. was continuous and systematic, without registering variations interphases as much detecting on vegetative as reproductive organs. F. decemcellulare and Pestalotiopsis sp. were recovered in vegetative organs. C. gloeosporioides was isolated in fruits pedicels. L. theobromae and Cladosporium sp. conidia were even detected within anthers along with the pollen grains. These results it is come off that the endophytic colonization is an important route for the development of diseases in the mango 'Haden' as dieback or decline, anthracnose and floral malformation cause by L. theobromae, C. gloeosporioides y F. decemcellulare, respectively.
