Poor shelf-life and sensitivity to environmental stress of entomopathogenic nematodes (EPNs) are traits, which deserve attention for improvement. Recently, a strong positive correlation between oxidative stress tolerance and longevity of Heterorhabditis bacteriophora dauer juveniles (DJs) has been reported. In this study, the improvement of H.
