The study was aimed at selecting species and strains of entomopathogenic nematodes to be used in practical control of the housefly in stables, which should provide welfare of bred animals. Test insect, the housefly, and entomopathogenic nematodes of the family Steinernematidae and Heterorhabditidae were used in experiments. Laboratory strains of nematodes and those commercially available in Poland and in Europe were used in performed tests. Larvae, pupae and imagines of M. domestica were cultivated in the Institute of Organic Industry in Warsaw. Four groups were created for each nematode species. Not all nematode species and strains were equally pathogenic to houseflies.

The aim of the paper was to identify the influence of magnesium on the preservation of pathogenic abilities of entomopathogenic nematodes living in soil contaminated with oil derivatives. Entomopathogenic nematodes living under natural conditions in soil or applied to soil as biopreparations for plant pest control are sensitive to soil contamination with heavy metals and oil derivatives. These nematodes do not respond directly by higher mortality but by a decrease in their pathogenic abilities, which adversely affects the success in searching and eliminating pests. A Polish commercial preparation called Owinema SC, containing infective juveniles of Steinernema feltiae Filipjev (Rhabditida: Steinernematidae), was used to test the effect of oil derivatives on pathogenicity and reproduction of entomopathogenic nematodes. Soil was polluted with petrol, diesel oil and used engine oil; the control was soil unpolluted with oil derivatives. Magnesium sulphate was also added (MgSO4∙H2O) in the amount of 160 mg per 1 liter of the suspension. The three oil derivatives in concentrations of: 0.3, 0.6 and 1.0 g or in double doses, i.e. 0.6, 1.2 and 2.0 g were poured over weighted soil batches. The control remained intact. Three replications of each treatment were made. Subsequently, Tenebrio molitor L. larvae used as bait inesct were placed in containers with the suspension. The bait insects were kept in the containers for 7 days, and afterwards they were removed from the soil and taken from the traps in order to check their mortality rate. Furthermore, to test the reproduction ability of entomopathogenic nematodes, dead larvae were moved to “islands” previously prepared according to the Dutky method. The results were presented as the number of entomopathogenic nematodes per 1 dead larvae of Tenebrio molitor L.

Similar patterns of hydrolases were observed in three species representing two genera of entomopathogenic nematodes: Steinernema affinis, S. feltiae, and Heterorhabditis zealandica. The same enzymes were present in the studied nematodes but they differed in the level of activity of individual sub-classes of enzymes. A higher activity of esterases and proteolytic enzymes could be observed for H. zealandica than for S. affinis and S. feltiae. On the other hand, the activity of glycosidases in steinernematids was generally much higher than in H. Zealandica.

Antibacterial properties of metal nanoparticles are well documented and known, but its potential use in agriculture as an anti pest agents – not. Possible negative or positive reactions with popular integrated pest management (IPM) methods need to be checked and verifi ed. The effect of copper nanoparticles on the mortality of entomopathogenic nematodes (EPNs) Steinernema feltiae from Owinema biopreparation was tested. This biopreparation is being used against serious agricultural pests. It was found that mortality of nematodes depends on nano- -Cu concentrations and on the length of contact of Steinernema larvae with nano-Cu solution. In this study the effect of different concentrations of nanoparticles on pathogenic properties of entomopathogenic nematodes – mortality of pest beetle Alphitobius diaperinus (Panzer, 1797) infected by EPNs and extensiveness of infection, was also studied. It showed that the high concentrations of Cu may decrease abilities of EPNs to enter, grow and proliferate inside the host body.

The aim of this study was to determine the effect of different initial doses of the infective juveniles (IJs) (50 IJs, 200 IJs, 1000 IJs) of Heterorhabditis megidis Poinar (Rhabditida: Heterorhabditidae) strain IsM15/09 on recovery, final yields and percent final yields in larvae Galleria mellonella ( L.). Percent recovery was not directly related to initial dose. Final yields also did not change with the initial dose. However, percent yields was highly negatively correlated with initial dose of nematodes and was the highest with the 50 IJs dose. Additional point of the study was to investigate whether the nematodes are able to produce progeny from one hermaphroditic individual. The results showed that the invasive larvae resumed growth and transformed into hermaphroditic individuals that reproduced without cross-fertilisation.

The paper presents the results of research on magnesium effect on beneficial enthomopathogenic fungi and nematodes as well as some predatory arthropods. Magnesium fertilization of soil contaminated with heavy metals does not significantly affect numbers of the majority of epigeal invertebrates, but it may influence numbers of single species, favouring the occurrence of some (Bembidion sp.) while restricting the presence of others (Harpalus rufipes De Geer). Magnesium synergism with heavy metal ions has been found to increase infectiveness and pathogenicity of enthomopathogenic fungi. Magnesium, in a dose of 160 mg⋅dm-3 present in the medium, significantly enhances pathogenicity of fungi, such as Beauveria bassiana, Paecilomyces farinosus, Paecilomyces fumoso-roseus or Metarhizium ansopliae. Increased pathogenicity of Steinernema carpocapsae and Heterorhabditis bacteriophora towards test insects has also been observed when magnesium ions were added to a solution in which these nematodes were kept. An effective magnesium dose differed depending whether the nematodes were used separately for test insects (450 mg⋅dm-3) or jointly with enthomopathogenic fungi (320 mg⋅dm-3). This protective effect of magnesium ions on beneficial microorganisms has also been observed in soil contaminated with heavy metals. An addition of magnesium to a solution in which enthomopathogenic nematodes were kept (160 mg⋅dm-3) and to a medium on which fungi were cultured (320 mg⋅dm-3) increased pathogenic abilities of these organisms in contaminated soil to a very high degree (10- to 300- fold higher than the natural heavy metal content in soil).

The olive fruit fly Bactrocera oleae is one of the most serious and economically damaging insects worldwide, affecting the quality and quantity of both olive oil and table olives. Laboratory bioassays were conducted for the first time to evaluate the susceptibility of B. oleae pupae to two entomopathogenic nematodes (EPN) species, Steinernema carpocapsae and Heterorhabditis bacteriophora. The nematodes tested caused pupal mortality of 62.5% and 40.6%, respectively. The most noteworthy result was obtained with S. carpocapsae which was able to infect 21.9% of the emerged adults. Since this tephritid fly spent several months in the soil as pupa, the use of EPNs could be a promising method to control this pest.
