“…In comparison between the reproductive potential of the low and high concentrations treated IJs, a significant decrease in the reproduction potential between low and high concentrations was noticed for all the tested materials. Contrasting the supposed by Jaworska et al [33] in which H. bacteriophora has high resistance than S. carpocapsae to Cu(II) ions, the opposite was found in this study where S. carpocapsae found more resistance towards Cu(II) ion, ligands and Cu(II) complexes than H. bacteriophora. A higher concentration of Cu(II) ion reduces beneficial mycorrhizal association.…”

New Schiff base ligands; (Z)‐1,5‐diphenyl‐2‐((thiophen‐2‐ylmethylene)amino)‐1H‐pyrrole‐3‐carbonitrile (L1); or (Z)‐2‐((2,4‐dihydroxybenzylidene)amino)‐1,5‐diphenyl‐1H‐pyrrole‐3‐carbonitrile (H2L2) and their Cu(II) complexes have been isolated and characterized using elemental analysis, spectral (FT‐IR, 1H NMR, UV/vis, EPR), molar conductivity and magnetic moment measurements, in addition to thermal techniques. FT‐IR spectra established that the Schiff base L1 coordinates as neutral bidentate or tridentate ligand. While the Schiff base H2L2 ligates as neutral or monobasic bidentate ligand. The EPR spectra indicated covalent nature of complexes [CuL1(OH)]Cl.2H2O (1), [CuL1(OH)(H2O)2]NO3.2H2O (2), [Cu(H2L2)Cl(H2O)3]Cl.H2O (5) and [Cu(HL2)NO3(H2O)3].H2O (6). The biological effect of Cu(II) ions, current ligands and complexes (1, 5) on the mortality and rate of reproduction of Entomopathogenic nematodes (Heterorhabditis bacteriophora and Steinernema carpocapsae) was studied. The results showed that, the obtained Schiff base ligands and their Cu(II) complexes make detoxification of the lethal effect of Cu(II) ions on the beneficial Entomopathogenic nematodes and complex (1) scored the highest reproduction potential.

“…In an experiment using soil strongly contaminated with heavy metals, decreased infectiveness of these beneficial microorganisms was found (ROPEK, GORCZYCA 2000). Analogously to enthomopathogenic fungi, a beneficial effect of magnesium ions was found for nematodes, visible as their increased pathogenicity (JAWORSKA et al 1996, JAWORSKA et al 1997. In experiments on stimulating enthomopathogenic activity of fungi and nematodes applied jointly on Galeria mellonella test insects it was found that, among three tested Mg ion concentrations, the concentration of 320 mg⋅dm -3 increased most infectiveness of the analyzed microorganisms.…”

“…The efficiency of these organisms may be modified by the effect of soil anthropogenic pollution such as heavy metals (JAWORSKA et al 1996, JAWORSKA et al 1997. Frequently, besides liming, magnesium fertilization of soils polluted with heavy metals is mentioned as a means to diminish their toxicity.…”

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).K e y w o r d s : magnesium, epigeal fauna, enthomopathogenic fungi, enthomopathogenic nematodes. 258 WP£YW MAGNEZU NA WYBRANE ORGANIZMY PO¯YTECZNEAbstrakt W pracy zestawiono wyniki badañ nad wp³ywem magnezu na po¿yteczne grzyby i nicienie owadobójcze oraz wybrane stawonogi drapie¿ne.Nawo¿enie magnezowe gleby ska¿onej metalami ciê¿kimi nie wp³ywa istotnie na liczebnooeae wiêkszooeci grup bezkrêgowców naziemnych, mo¿e jednak wp³ywaae na liczebnooeae pojedynczych gatunków, sprzyjaj¹c wystêpowaniu jednych (Bembidion sp.), a ograniczaj¹c wystêpowanie innych (Harpalus rufipes De Geer).Stwierdzono synergizm magnezu z jonami metali ciê¿kich w podnoszeniu infekcyjnooeci i patogenicznooeci grzybów owadobójczych.

“…There is more accumulation of heavy metals in the areas where agricultural activities such as fertilizing are conducted than in natural areas (Campos-Herrera et al 2010). Some heavy metals have a direct lethal effect on EPNs and, if not lethal, reduce their ability to infect hosts (Jaworska et al 1996;Jaworska et al 1997;Sun et al 2016). In addition, EPNs were found to be more susceptible to heavy metals in the soil than plant parasitic nematodes (Sun et al 2016).…”

Bazı inorganik gübrelerin entomopatojen nematodlar (Steinernema feltiae Tur-S3 ve Heterorhabditis bacteriophora HBH) üzerine etkileri Öz: Entomopatojen nematodlar (EPN'ler) özellikle toprakta yaşayan zararlı böceklere karşı biyolojik mücadelede kullanılmakta, çevreye ve insan sağlığına olumsuz bir etki göstermemektedirler. Toprak içerisinde uzun süre etkin olup konukçusunu arayabilme özelliğine sahiptirler. Yaşam döngülerinin büyük bir bölümünü toprak içerisinde geçiren EPN'ler, gübreleme, toprak işleme ve sulama gibi tarımsal faaliyetlerden etkilenebilir. Bu çalışmada bazı kimyasal gübrelerin, EPN'lerin canlılığı üzerine gösterdiği doğrudan etkiyi belirlemek için yürütülmüştür. Bu amaçla, tarımda yoğun olarak kullanılan altı inorganik gübre ve iki EPN (Steinernema feltiae Tur-S3 ve Heterorhabditis bacteriophora HBH) ırkı seçilmiştir. Laboratuvar koşullarında 1gr/l, 5gr/l ve 10gr/l gübre dozları uygulanıp, 10 gün boyunca incelenmiştir. İnorganik gübrelere karşı S. feltiae (Tur-S3) ırkının H. bacteriophora (HBH)' dan daha dirençli olduğu, ancak DAP, NPK ve NP'nin gübrelerinin her iki EPN ırkını da olumsuz etkilediği tespit edilmiştir. DAP, NPK ve NP' nin öldürücü etkisi diğer gübrelere göre daha yüksek bulunmuştur.
