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.

Products based on different strains of entomopathogenic fungi are now being used in Integrated Pest Management (IPM) programs. Compatibility studies of chemical and biological control agents are necessary to be able to give proper recommendations for their integrated use. The effect of three insecticides based on imidacloprid, spinosad and abamectin, and three fungicides based on chlorothalonil, azoxystrobin and thiophanate-methyl on the activity of the following entomopathogenic fungi: Metarhizium anisopliae (Metschn.) sensu lato, Beauveria bassiana (Bals.-Criv.) Vuill., Acremonium sp. was tested under laboratory conditions. Tests of the influence of the pesticides on growth and production of conidia were performed. From this study, we concluded that all tested insecticides can be applied together with fungus B. bassiana products in IPM programs. They even stimulate sporulation of this fungus at the recommended dose, 0.5 of the recommended dose and 1.5 times the recommended dose. In the case of fungicides we observed inhibition of growth and sporulation of B. bassiana and reduction of growth and sporulation of other species of fungi.

We carried out an experiment with using the entomopathogenic fungus Beauveria bassiana (Bals.) Vuill. for sanitation of active infested trees. We used 15 active infested trees from which 5 stems were treated with an insecticide, 5 were treated with solution of the tested entomopathogenic fungus and 5 were left as control. The used insecticide was pyretroid Fury 10 EW. We used a biopreparation based on the entomopathogenic fungus B. bassiana in form of wettable powder. The material was diluted. The suspension contained 107spores of the tested entomopathogenic fungus in 1 ml. The suspension was applied across the whole stem surface. We succeeded to infect about 28.75% of Ips typographus L. individuals in the treated stems. The number of live individuals was comparable with the variant using the insecticide.

The epidemiological and epizootic importance of ticks has been known for a few decades since of the discovery of their role as vectors of many new diseases, and the better detection of those already known. Given the durability of chemical preparations in the environment and the increasing problem of developing tick resistance, natural strategies for biological control are sought. A promising alternative to chemical pesticides is the use of entomopathogenic organisms for effective integrated pest management of low environmental impact. A number of promising microbes have been identified during the search for effective means of controlling the tick population, but the knowledge about the impact of these pathogens on the environment and other non-target organisms is still insufficient. Previous research has still not provided a definite answer about the safety of their use. It is known, however, that the chemicals which are currently used have a negative impact on the environment and/or cause resistance. No efficient biocompound has yet been devised for commercial use. Potential microorganisms for tick biocontrol (mainly bacteria and fungi) are natural tick pathogens, living in the same environment. With their adhesive properties, and their ability to digest the cuticle, they may constitute an appropriate ingredient of bioacaricides. Until now, fungal insecticides have been used only to control crop pests.

The present work aimed at investigating diversified organic treatment including sewage sludge on the insecticide activity of enthomopathogenic fungi and nematodes. Crude sludge from biological tannery sewage treatment plant and vermicomposts based on the sludge with added straw and fruit tree leaves were used for the experiment. Organic treatment significantly affected pathogenic properties of enthomopathogenic nematodes naturally present in the soil of the investigated plots. The highest death rate among trap insects was detected in the soil from untreated plots or fertilised by farmyard manure and vermicomposts. Nematodes from examined plots reproduced in varying numbers depending on the treatment applied on individual plots. The lowest number of invasive larvae was obtained for nematodes from plots fertilised by straw vermicompost, (crude)sewage sludge and hair. The applied organic treatment influenced also insecticide activity of the applied nematodes towards G. mellonella larvae. The highest death rate of G. mellonella larvae was observed in the soils treated with organic fertilisers and farmyard manure. Clear decrease in B. bassiana pathogenic properties was detected in soil fertilised with sewage sludge and hair. Chemical sludge and fertilisation with hair caused also a clear decrease in S. carpocapsae pathogenic properties towards G. mellonella larvae. The obtained results reveal unfavourable effects of crude sewage sludge on the pathogenic properties of enthomopathogenic fungi and insects. Vermicomposts obtained from this sludge revealed a positive influence on the microorganisms. This fact may indirectly improve health conditions of plants.

Six fungal species, Aspergillus flavus Link ex Fr., Beauveria bassiana (Bals.) Vuill., Acremonium sensu Gams, Fusarium sp. Link ex Fr., Paecilomyces farinosus (Holm. ex Gray) Brown et Smith as well a Paecilomyces fumosoroseus (Wize) Brown et Smith, have been isolated as result of studies on entomopathogenic fungi of the satin moth Stilpnotia salicis. The epizootic induced by the fungus B. bassiana in 1994 caused about 92% reduction of the pest population. That has been noted for the first time in a natural population of S. salicis in Poland.

The study was aimed at estimating species composition and abundance of entomopathogenic fungi in the Chojnowski Landscape park. The effect of site, season (spring, summer, autumn) and temperature on the frequency of isolation of entomopathogenic fungi was also analysed. The effect of the first two factors was estimated based on the analysis of soil samples taken from meadow 1, forest 1 and orchard in spring, summer and autumn 2010. Three species of entomopathogenic fungi (Beauveria bassiana, Metarhizium anisopliae and Isaria fumosorosea) were isolated in the study area. Site and temperature affected the frequency of isolation of particular species. On meadow 1 and in orchard M. anisopliae appeared to be the dominating species while forest 1 was dominated by B. bassiana. From among meadow and forest sites sampled in the autumn, forest 3 (nature reserve) was characterised by the highest density of entomopathogenic fungi. M. anisopliae and B. bassiana were most often isolated from meadow sites while B. bassiana and I. fumosorosea - from forest sites. B. bassiana and I. fumosorosea infected insects with significantly higher frequency at 20°C than at 25°C.

The aim of the study was determination of number and species composition of entomopathogenic fungi for two river catchments: Zwolenka and Zagozdzonka. Both are left side tributaries of the Vistula River and have different geological structure. The area is dominated by mosaic of extensive agriculture and forests. Three species of entomopathogenic fungi were found: Beauveria bassiana, Metarhizium anisopliae, Isaria fumoso-rosea. The dominant species in both catchment basins was I. fumosorosea. Infections caused by other factors were also noted (48% by entomopathogenic nematodes of the family Steinernematidae, remaining 19% by mites, saprophytic fungi, non-fruiting mycelia and other unidentified factors).

The entomopathogenic fungus conidia viability and sporulation may be affected by different environmental factors or by bio-pesticides and chemical products used to protect cultivated plants. In this research, we investigated the compatibility of Metarhizium anisopliae DEMI 001 isolates with three insecticides: fipronil, pyriproxyfen and hexaflumuron. The effect of fipronil, pyriproxyfen and hexaflumuron on sporulation, vegetative growth and conidial germination of the fungus was studied based on measuring the vegetative growth and sporulation. SDA medium was mixed with fipronil (10, 40 and 120 ppm), pyriproxyfen (10, 500 and 1 000 ppm), hexaflumuron (20, 50 and 120 ppm). SAD medium excluding insecticides was designated as blank. To determine the sporulation rate, spores was counted on surface area and vegetative growth was measured on the basis of colony diameter. The results showed that hexaflumuron at the concentration of 120 ppm reduced the vegetative growth to 0% showing the highest reduction effect compared to pyriproxyfen (24.59%) and fipronil (24.31%). All three insecticides reduced drastically the conidial germination at the highest concentrations (0-15%). Hexaflumuron treatment with 0% germination at all three concentrations and fipronil and pyriproxyfen with 32.36% and 9.7% germination at 200 ppm were not significantly different. Regarding the highest negative effect of hexaflumuron on germination at all three concentrations, this insecticide should not be applied together with the entomopathogenic fungus.
