dc.description.abstractThe olives and olive oil production are important agricultural activities in Portugal. In the region of Trás-os-Montes, olive orchards are strongly affected by Prays oleae Bern., which is responsible for high losses in the olive production, as much as 40% of the expected yield. This lepidopteran presents three generations per year (phyllophagous, antophagous and carpophagous) that damage the olive tree in different organs (leaves, flowers and fruits, respectively). In an attempt to identify fungi that might cause the death of olive moths, larvae and pupae of those three annual generations were collected and surveyed for natural fungal infection. After their isolation, the fungal agents were molecularly identified by sequencing the amplified internal transcribed spacer (ITS) region of rDNA. In the present work, the diversity of fungal species associated to P. oleae, in several olive orchards located in Trás-os-Montes region, is discussed. The diversity and abundance of fungal species differed between all three generations. Higher diversity was found in the carpophagous generation, followed by the antophagous and phyllophagous generations. The use of already adapted fungal species to control one of the major pests of olive groves will increase the success of a future biocontrol strategy. In this context, the identification of fungi associated to P. oleae from olive orchards provided a pool of potential biocontrol agents. In this work, Beauveria bassiana proved to be the most promising fungus to be used as biocontrol agent against olive moth, being strongly associated to the phyllophagous generation. Other fungal species presenting entomopathogenic, antagonistic and phytopathogenic characteristics were also found.por
