Biodiversity of arthropod pathogens in the Bialowieza Forest

100%

Journal of Plant Protection Research

2004

tom 44

nr 4

In the years 2002–2004 strains of Bacillus thuringiensis and 37 species of entomopathogenic fungi were isolated and identified in the Polish and Belarussian parts of Białowieża Forest (BF). Mitosporic fungi and bacteria dominated in litter superficial soil layer, forest, litter and floor vegetation whereas entomophtoralen fungi prevailed in bushy undergrowth layers and tree crowns. The dominant species Beauveria bassiana was observed in forest floor, subcortical habitats on dead trees, meadows and rushes. The species Entomophthora israelensis, Beauveria cf. bassiana, Paecilomyces suffultus and P. tenuipes were for the first time described as insect pathogens in BF. Entomophthorales seem to hold much greater part than mitosporic forms in the whole diversity of entomopathogenic fungi. Relatively rich sets of these fungi recognised in BF during last decades confirm the predestination of this area as highly significant refuge for other groups of arthropod pathogens, and it should encourage scientists to widen their research and contribute to a rather scarce knowledge in this field.

W latach 2002–2004 na terytorium białoruskiej i polskiej części Puszczy Białowieskiej prowadzono badania nad patogenami stawonogów. Po stronie białoruskiej z 73 prób wyizolowano 27 izolatów mikroorganizmów, wśród których dominowały bakterie. W części polskiej badania skupiły się tylko na patogenach grzybowych. Izolowano 37 gatunków grzybów. Dominantami w ściółce leśnej i powierzchniowej warstwie gleby były grzyby mitosporowe, natomiast w podszycie i koronach drzew – grzyby owadomorkowe. W zbiorowiskach łąkowych i szuwarowych dominowały gatunki grzybów z rodzaju Gibellula. Gatunki Entomophthora israelensis, Beauveria cf. bassiana, Paecilomyces suffultus i P. tenuipes nie były dotychczas opisane i izolowane w Puszczy Białowieskiej.

Ecological information concerning 292 fungal taxa is reported as a result of two surverys in the Biebrza National Park. Most data presented come from the 5-day all-fungi inventory of the Polish Mycological Society in 2013, and 47 species were recorded during studies in the Biele Suchowolskie fen in 2008/2009. In total, 27 species of zygomycetes, 232 ascomycetes (including anamorphs) and 27 basidiomycetes (mainly Pucciniales). Additionaly some representatives of fungi-like organisms from Stramenopiles (4 species) and Dictyostelia (2) were identified. Fungal groups included were the same as in the previous survey in 2012: 190 taxa associated with plants, 15 with animals, 8 with fungi and 71 isolated from soil, plant debris and animal excrements. The most numerous were anamorphic ascomycetes (159 species). Nineteen species have not been previously known from Poland and 31 species are rare (1–3 localities). For the Biebrza National Park 197 species (67.5%) are new.
