Mycobiota associated with the ambrosia beetle Megaplatypus mutatus: Threat to poplar plantations
Megaplatypus mutatus (syn. Platypus sulcatus) is an ambrosia beetle native to South America, which represents the main forest pest in Argentina of Poplar plantations and is also an emerging pest in Europe, representing a potential risk to forest and fruit plantations globally due to its low specific...

The fungal community of 28 attacked trees was studied by evaluating 1104 gallery fragments and 110 fragments of insects. Fungal isolates were identified using morphology and phylogenetic analysis of the internal transcribed spacer region of nDNA. Nineteen taxa were identified, the most relevant Fusarium solani species complex, three species of Raffaelea and Graphium basitruncatum. Despite the lower frequency occurred by Raffaelea spp. and G. basitruncatum, we detected a specificity between male/female and location in the gallery. Additionally, the topology of the galleries is described based on analyses with computed tomography and nuclear magnetic resonance. Enhancing these techniques, an image combining both data was produced, suggesting that the water circulation across outer sections might be involved in the modulation of the gallery topology. © 2016 Institute of Chartered Foresters.
