Serratia marcescens SM001-induced oxidative stress accelerates Spodoptera frugiperda mortality by promoting midgut apoptosis.
Spodoptera frugiperda (fall armyworm) is a globally distributed and highly destructive migratory pest, while Serratia marcescens is a widespread entomopathogenic bacterium capable of infecting diverse insects. In this study, oral infection with S. marcescens strain SM001 exhibited potent virulence, with an LC50 of 7.40...
