Opis:: Celem pracy była ocena wpływu spinosadu (SpinTor 240 SC), preparatu dopuszczonego do stosowania w rolnictwie ekologicznym oraz dwóch syntetycznych pyretroidów (Karate Zeon 050 CS i Sumi - Alpha 050 EC) na wzrost kolonii pięciu gatunków grzybów owadobójczych: Hirsutella nodulosa, Isaria farinosa, Isaria fumosorosea, Lecanicillium sp. i Metarhizium anisopliae. Testowane w doświadczeniu laboratoryjnym insektycydy dodane do podłoża hodowlanego w zalecanej dawce polowej w nieznacznym stopniu wpływały na ograniczenie wzrostu kolonii badanych grzybów owadobójczych. Największą wrażliwością na obecność badanych insektycydów w podłożu hodowlanym, odznaczał się grzyb Hirsutella nodulosa, natomiast najmniejszą Metarhizium anisopliae i Isaria fumosorosea. Dopuszczony do stosowania w rolnictwie ekologicznym insektycyd SpinTor 240 SC, wykazał mało toksyczne działanie w stosunku do grzybów entomopatogenicznych. Najbardziej inhibicyjne działanie na wzrost badanych grzybów wykazał insektycyd Sumi-Alpha 050 EC.
The aim of this study was to assess the impact of spinosad (SpinTor 240 SC) formulation approved for use in organic farming, and two synthetic pyrethroids (Karate Zeon 050 CS and Sumi - Alpha 050 EC) on the growth of five species of entomopathogenic fungi: Hirsutella nodulosa, Isaria farinosa, Isaria fumosorosea, Lecanicillium sp. and Metarhizium anisopliae. Tested in a laboratory experiment insecticides added to the culture medium at the recommended field dose slightly affected the colony growth of investigated fungi. The fungus Hirsutella nodulosa was the most sensitive for the presence of insecticides in the culture medium, while the smallest sensitivity showed Metarhizium anisopliae and Isaria fumosorosea. Approved for use in organic farming insecticide SpinTor 240 SC, showed little toxicity to entomopathogenic fungi. Insecticide Sumi - Alpha 050 EC showed the most inhibitory effect on the growth of tested fungi.

Opis:: This study compared the species composition and rate of entomopathogenic fungi occurrence in cultivable soil following the application of a mineral-and-organic fertiliser produced from brown coal. The material for testing consisted of soil samples collected in the second year of the experiment on two dates in 2015 (spring and autumn). The experiment was carried out on the following plots: control plot (no fertilisation); a plot fertilised with mineral fertilisers NPK presowing + N₆₀ for top dressing; a plot fertilised with NPK presowing + manure; a plot fertilised with a fertiliser produced from brown coal at a dose of 1 t/ha NPK presowing + N₂₀ for top dressing; and a plot fertilised with a fertiliser produced from brown coal at a dose of 5 t/ha NPK presowing + N₄₀ for top dressing. Entomopathogenic fungi were isolated from soil of particular fertilisation experiment plots using insect traps (Galleria mellonella larvae) as well as a selective medium. Three species of entomopathogenic fungi, i.e. Beauveria bassiana, Metarhizium anisopliae s.l. and Isaria fumosorosea, were isolated using two methods, from the soil samples collected from particular fertilisation experiment plots on two dates, i.e. spring and autumn. Fungus M. anisopliae s.l. proved to be the predominant species in the tested soil samples. The addition of the mineral-and-organic fertiliser, produced based on brown coal, to the soil at both applied doses contributed to an increase in the number of infectious units (CFUs) of entomopathogenic fungi formed in relation to the control plot.

Opis:: Results of studies on diversity of arthropod-pathogenic fungi in selected habitats in Austria and Poland carried out in the years 2006-2007 and 2009-2010 are discussed. In total 47 species of entomopathogenic fungi were found as pathogens of different arthropods in Austria. Twenty six entomophthoralean species from different insects and one species from mites were identified and 16 of them are recorded as new to Austria. From among 21 species of anamorphic Hypocreales (Ascomycota) affecting arthropods in Austria, 13 species so far have not been known from this country. In total 51 species of fungi affecting different arthropods in Poland were recorded, among them 28 species of Entomophthorales and 23 anamorphic Hypocreales were separated. The most frequent species of the entomopathogenic fungi both in agricultural and afforested areas in Austria were the common and usually worldwide distributed cordycipitaceous anamorphs Beauveria bassiana, Isaria fumosorosea and in areas of this study less numerous I. farinosa. The most frequent pathogens occurring in mite communities on plants and in wood infested by insects were Hirsutella species. Several entomophthoralean species developed epizootics that caused high reduction in host populations of different arthropods in both countries. Especially interesting is the first record of mycoses (up to 60% mortality), caused by Zoophthora spp. on Phyllobius beetles in a mixed forest near Białowieża. During our joint research, we found the first time in Poland and Europe, the presence of the fungus Furia cf. shandongensis on earwigs and Hirsutella entomophila on Ips typographus adults in forest habitats. From the feeding sites of the latter bark beetle and other subcortical species in oak bark (mostly Dryocoetes villosus) and D. alni in black alder over a dozen of various Lecanicillium strains - including few of the features not allowing to classify them to any of so far known species – were isolated both from the scolytids and from accompanying them mites, but these materials have now been successively elaborated. From the commonly occurring in these materials acaropathogenic species Hirsutella cf. brownorum, H. minnesotensis, H. nodulosa and H. rostrata, the two latter infected also adult bark beetles, whereas from the larvae and pupae some supposed nematophagous anamorphs were isolated, among them Harposporium janus and Haptocillium sp.
W latach 2006-2007 oraz 2009-2010 w ramach dwustronnej współpracy (Scientific and Technological Cooperation Project: Austria - Poland 12/2006 i 09/2009), w wybranych siedliskach w Austrii i w Polsce prowadzono badania nad grzybowymi patogenami stawonogów, głównie owadów i roztoczy. W sumie w Austrii stwierdzono występowanie czterdziestu siedmiu gatunków grzybów patogenicznych w stosunku do stawonogów. Wśród nich odnotowano 26 gatunków owadomorków (Entomophthorales), z czego 16 to gatunki niewykazywane wcześniej z tego kraju oraz 21 gatunków grzybów reprezentowanych przez anamorficzne formy Hypocreales (Ascomycota), w tym 13 gatunków nowych dla Austrii. Spośród 51 gatunków grzybów patogenicznych dla stawonogów, które rozpoznano w ramach badań prowadzonych w Polsce, 28 należało do owadomorków, a 23 to anamorfy workowców (Ascomycota), z których 13 gatunków wykazuje właściwości patogeniczne w stosunku do roztoczy. Do gatunków grzybów najczęściej spotykanych na roztoczach fitofagicznych oraz występujących w zbiorowiskach owadów zasiedlających drewno, należały gatunki z rodzaju Hirsutella, z których żaden nie był dotąd notowany w Austrii. Spośród nich tylko H. kirchnerii i H. thompsonii wydają się w istotny sposób redukować populację szpecieli w obu krajach. Dwa nowe gatunki Hirsutella danubiensis i H. vandergeesti, opisane w 2008 roku, są efektywnymi patogenami szkodliwych roztoczy z rodziny przędziorkowatych (Tetranychidae), chociaż ostatni z wymienionych gatunków pasożytuje również na roztoczach drapieżnych (Phytoseidae). Kilka gatunków owadomorków powodowało epizoocje, które wpłynęły na znaczne ograniczenie populacji różnych taksonów stawonogów w obu krajach. Szczególnie godny uwagi jest przypadek wysokiej śmiertelności (do 60% osobników w populacji) chrząszczy z rodzaju Phyllobius zaobserwowany w Puszczy Białowieskiej, a spowodowany przez nieopisany dotychczas gatunek grzyba z rodzaju Zoophthora. Efektem wspólnych badań jest także odnotowanie po raz pierwszy w Polsce i w Europie, występowania Furia cf. shandongensis na skorkach (Dermaptera) oraz Hirsutella entomophila na imagines Ips typographus w siedliskach leśnych.

Opis:: The effect of three pesticides used in corn protection: Targa Super 05 (chizalofop-P-ethyl), Roundup 360SL (glyphosate) and Karate Zeon 050CS (lambda-cyhalothrin), on the growth of entomopathogenic fungi Hirsutella nodulosa Petch and Beauveria bassiana (Bals.) Vuill. was evaluated under laboratory conditions. Fungi isolates were cultured on Sabouraud’s medium with addition of pesticides at three different concentrations. H. nodulosa was more susceptible to pesticides than B. bassiana. The most inhibitory effect on tested entomopathogenic fungi showed chizalofop-P-ethyl herbicide. Lambda-cyhalothrin at the recommended field dose showed minor toxic effect on entomopathogenic fungi, which suggests the possibility of compatible use of this insecticide with biopesticides based on the tested species.

Opis:: The occurrence of entomopathogenic fungi, involved in regulating the population of insects preying on arable crops, depends on numerous factors, such as using crop protection chemicals, which are prohibited in the organic tillage system. Using two methods: selective medium and the Galleria mellonella bait method, the species composition and the occurrence of entomopathogenic fungi in soils deriving from organic and conventional fields sown with winter cereals were compared. Four en-tomopathogenic fungal species were identified in the samples: Beauveria bassiana, Isaria fumosorosea, Metarhizium anisopliae and Lecanicillium sp.. M. anisopliae was the most frequently detected one. M. anisopliae and B. bassiana formed more colony forming units in soils from organic fields, whereas I. fumosorosea in soils from the conventional ones.

Opis:: This study focused on the effect of heavy metal cobalt ions (at concentrations of 1–1000 ppm) on the development and enzymatic activity of four entomopathogenic fungi: Beauveria bassiana, Beauveria brongniartii, Isaria fumosorosea and Metarhizium robertsii, commonly used in biological plant protection. It was found that each of the tested species of fungi reacted individually to contact with the Co2+ ions at their various concentrations. Depending on the variants of the experiment carried out, there were changes in the development of the mycelia (mainly growth inhibition) and their morphological features (color and structure) in comparison to the control samples. Co2+ ions had a fungistatic effect on all fungal strains, whereas a fungicidal effect was noted at concentrations of 750 ppm and 1000 ppm against M. robertsii and I. fumosorosea, respectively. In addition, there was a discrepancy in enzymatic activity between the tested fungal species developing in the medium with varying concentrations of metal salt. The inhibitory effect of Co2+ ions on lipase production was observed in I. fumosorosea. Protease production was stimulated in B. bassiana at all Co2+ concentrations, whereas in M. robertsii this effect was noted at 1 ppm. The changing dynamics of extracellular fungal hydrolases, due to the action of Co2+ ions, may translate into the role of these microorganisms in the processes of insect pathogenesis. This work suggests that severe pollution of the environment by cobalt could be a restrictive factor for the development and pathogenicity of entomopathogenic fungi and must be taken into account for their successful application in biological plant protection.

Opis:: In this in vitro study, the influence of tin ions at concentrations of 1–1,000 ppm on the development and enzymatic activity of four entomopathogenic fungi (Beauveria bassiana, B. brongniartii, Isaria fumosorosea, and Metarhizium robertsii), that are commonly used in biological plant protection, are examined. Each of the fungal species tested reacted differently to contact with the Sn2+ ions at the tested concentrations. Exposure to Sn2+ ions affected the rate of development, morphology, and enzymatic activity of fungi. Of the four fungal species studied, M. robertsii was the most resistant and showed complete growth inhibition at the highest Sn2+ concentration tested (1,000 ppm). For the other entomopathogenic fungi, the fungicidal effect of Sn2+ ions was noted at the concentration of 750 ppm. Exposure to Sn2+ ions (up to 500 ppm) resulted in enhanced biochemical activity; and all entomopathogens that were tested showed increased production of N-acetyl-β-glucosaminidase (NAG) as well as several proteases. Moreover, B. brongniartii and M. roberstii showed increased lipases synthesis. These changes may increase the pathogenicity of the fungi, thereby making them more effective in limiting the population of pest insects. The exposure of the entomopathogenic fungi to a medium containing Sn2+ ions, at concentrations that were appropriate for each species, induced hyperproduction of hydrolases, which might be involved in aiding the survival of entomopathogenic fungi in the presence of heavy metals. This study shows that the fungistatic effect of Sn2+ on entomopathogenic fungi did not restrict their pathogenicity, as evidenced by the stimulation of the production of enzymes that are involved in the infection of insects.
