Virulence and pathogenesis of the baculovirus Autographa californica M nucleopolyhedrovirus (AcMNPV) in Pseudoplusia includens larvae

► Pseudoplusia includens displays no physiological barriers to fatal AcMNPV Infection. ► The optical brightener M2R does not significantly increase virulence. ► P. includens could be controlled in organic crops using naturally occurring AcMNPV.
