Fungal communities associated with bark and ambrosia beetles trapped at international harbours

摘要: Abstract Bark and ambrosia beetles (Coleoptera; Scolytinae) establish trophic relationships with fungi, which could be also agents of plant diseases. Orthotomicus erosus (Wollaston) Xyleborinus saxesenii (Ratzeburg) are two species Palaearctic origin that have been introduced in several countries around the world. Here, we investigated their associated fungal communities using individuals trapped at harbours native range, without strictly focusing on nutritional symbionts. Targeting ITS2 region rDNA through pyrosequencing, retrieved taxa known to diseases, never previously reported these beetle species, sequence clusters not linked any fungus. These findings underline surveillance should extended fungi bark beetles, taking into account role as potential vectors pathogens.
