REMEŠOVÁ J., KOLAŘÍK M., PRÁŠIL K. (2007): Microfungi on the kernels of transgenic and non-transgenic maize damaged by the European corn borer. [Bt-maize, microfungi, plant protection, European corn borer, Zea mays] Czech Mycology 59(2): 205-213 (published: 28th December, 2007)
abstract
From 2002–2004 isolations were carried out to determine the kinds and abundance of microfungi from non-transgenic maize kernels damaged by the European corn borer (ECB) and from transgenic Bt-maize (enriched with delta-endotoxin from the soil bacterium Bacillus thuringiensis). Bt-maize and non-transgenic maize (Zea mays) were grown at Praha-Ruzyně and Ivanovice na Hané, Czech Republic. Thirty-one taxa of filamentous microfungi were isolated, including eight zygomycetes and twenty-three ascomycetes (anamorphic stage). Presence of ECB, corn treatment, year, locality and isolation method significantly accounted for differences in fungus communities. Bt-maize was significantly different from the treatments with non-transgenic hybrids and was often associated with the potentially toxinogenic fungi Alternaria alternata and Epicoccum nigrum. Conversely, Bt-maize had lower incidences of Fusarium spp. and Acremonium strictum.

abstract
The oak bark beetle (Scolytus intricatus, Scolytidae, Coleoptera) was studied during the years 1997-2003 with respect to the occurrence of microscopic fungi on the surface of its body. Samples were collected in eight localities in the Czech and Slovak Republics. The investigation was focused on all different stages of the beetle’s life cycle: eggs, larvae, adults be for e emergence, adults in generation and maturation feeding (nearly 600 samples), and also on galleries (400 samples). The most frequent fungi associated with S. intricatus were yeasts, Geosmithia spp. and Penicillium spp. Ophiostomatoid fungi were isolated, too. Great attention was paid to the occurrence of Geosmithia spp., which were so far recorded rarely. They were frequently found in all stages of the life cycle of Scolytus intricatus, except for males in maturation feeding. The ecology of Geosmithia spp. in feedings of phloem inhabiting insects is discussed for their negative cellulase production and the ecology of associated insect species. Trees infested with Scolytus intricatus represent a major and still little explored niche of Geosmithia spp.
KUBÁTOVÁ A., NOVOTNÝ D., PRÁŠIL K., MRÁČEK Z. (2000): The nematophagous hyphomycete Esteya vermicola found in the Czech Republic. [conidial fungi, Esteya vermicola, Bursaphelenchus eremus, Scolytus intricatus, nematodes, bark beetles] Czech Mycology 52(3): 227-235 (published: 7th December, 2000)
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.
