Native, introduced and foreseen ambrosia beetles on woody plants in Hungary.
Damages caused by Scolytid beetles (Curculionidae, Scolytinae) have increased significantly in recent decades both in Europe and Hungary. This is due, on one hand, to the changing climatic conditions and some abiotic effects (e.g. windbreak, ice damage), followed by the mass mortality of conifer forests (primarily spruce); on the other hand, due to alien, sometimes invasive species, which have been introduced recently from other continents. The first one is mainly caused by bark beetles, where we have a considerable amount of information on their biology, damage and possible control. However, in the second group, the proportion of ambrosia beetle species is significant, where the relevant information is either incomplete (native species) or missing (alien species). The present article covers the native (Xyleborinus saxesenii, Xyleborus cryptographus, X. dispar, X. dryographus, X. eurygraphus, X. monographus, X. pfeilii, Trypodendron domesticum, T. lineatum, T. signatum, Platypus cylindrus) and introduced (Xylosandrus germanus, Xyleborus qffinis, Gnathotrichus materiarius) ambrosia beetles of Hungary and provides a brief overview of other potentially invasive species. This is the first report of Gnathotrichus materiarius in Hungary.
