Identification of fungal pathogens of Pinus longaeva (Great Basin Bristlecone pine).

Pinus longaeva, also known as the Great Basin Bristlecone pine is found naturally almost exclusively in California, Nevada and Utah. It was instrumental in calibrating carbon dating due to its longevity, some trees dating back 4800 years and still living. It is known to survive in hostile environments because of its ability to deal with extreme wind, drought and temperature. This study aims to identify the fungal pathogens affecting this pine. Three types of fungi were consistently isolated from the host tissue: Aspergillus niger, Alternaria and Eppicoccum. Essential oils were used to study the effect of them in the fungi isolated, the results are presented. During the process of isolation of the fungus, an infestation by Chionaspis pinifoliae was observed. The number of scales and eggs produced is reported. We are in the process of analyzing other scale insects found in the plant. Future experiments will aim to identify additional fungi (epiphytic, saprophytic or pathogenic) and to identify the causal agent of the symptoms shown in the plant studied.
