Mycobiota in the galleries of the fir pinhole borer Treptoplatypus oxyurus (Dufour, 1843)

Jelin valjkasti srčikar (Treptoplatypus oxyurus) je jedan od dvije palearktičke vrste srčikara koji obitava u Hrvatskoj dok u susjednim zemljama nije otkriven. Biologija kukca nije dovoljno istražena u Hrvatskoj, ali i u svijetu stoga je važno nastaviti pratiti i istraživati biologiju i uvjete pridolaska vrste. Pripada redu kornjaša koji napada i oštećuje drvo jele (obične i grčke) u kojem buši hodnike. Sva istraživanja koja su provedena ukazuju na obligatni odnos jelinog valjkastog srčikara s gljivama stoga je napravljena mikobiološka obrada uzoraka drva uzetih sa zaražene jele. Unutar istražene zajednice gljiva koje dolaze u hodničnom sustavu kukca, najzastupljenija je skupina kvasaca (Candida sp.) i vrsta crvenorubna guba (Fomitopsis pinicola).Ambrosia beetle (Treptoplatypus oxyurus) is one of the two Palearctic species of wood-boring weevils which inhabit forests of Croatia, while it has not been detected in adjoining countries. Biology of ambrosia beetles has not been sufficiently researched in Croatia nor in the world, so it is important to continue monitoring and researching biology and habitat conditions of the species. It is classified in the genus of beetles that attack and damage fir wood (specifically of silver and black mountain fir) in which it bores galleries. All research to date indicates symbiosis between ambrosia beetle and fungi, therefore mycobiological processing of infected fir wood specimens was performed. Within researched fungal community that appears in the galleries of the insect, the most common are yeasts (Candida sp.) and the red-belted bracket (Fomitopsis pinicola)
