abstract
During a study of surface mycoflora of the bark beetle Scolytus intricatus (Coleoptera: Scolytidae), the hyphomycetous microfungus Esteya vermicola was found associated with Bursaphelenchus eremus (Nematoda: Aphelenchoididae). Esteya vermicola and Bursaphelenchus eremus were recorded in the Czech Republic for the first time. The find of E. vermicola is considered to be these cond one in the world. Esteya vermicola is a nematophagous species with two types of conidia, described in 1999 from the pinewood nematode Bursaphelenchus xylophilus in Taiwan. Our new records are from the surface of larvae and adult beetles of Scolytus intricatus and their galleries under bark of branches of three species of oak (Quercuspetraea, Q. polycarpa, and Q. robur) on several localities in the Polabí and Křivoklátsko regions, Czech Republic. A description of morphological features and drawings of the fungus are given. Examined strains are maintained in the Culture Collection of Fungi (CCF), Faculty of Science, Charles University, Prague and Czech Collection of Microorganisms (CCM), Faculty of Science, Masaryk University, Brno.
