The effect of gold nanoparticles on the mortality and pathogenicity ofentomopathogenic nematodes from Owinema biopreparation

Abstract: The effect of gold nanoparticles on the mortality of entomopathogenic nematodesSteinernema feltiae from Owinema biopreparation was studied. The effect of differentconcentrations of nano-Au on pathogenic properties of entomopathogenic nematodes was alsostudied. It was found that mortality depended on nano-Au concentrations and on the time oflarval contact with them.
