Maize mycorrhizas decrease the susceptibility of the foliar insect herbivore <i>Spodoptera frugiperda</i> to its homologous nucleopolyhedrovirus

Abstract

Our results show that AMF can modulate S. frugiperda-SfMNPV interactions via plant-mediated phenotypic responses to the mycorrhizal association and are most likely linked with increased leaf food quality for S. frugiperda. These results call for further studies to address the mode of interaction and possible implications for pest management in maize agroecosystems. © 2021 Society of Chemical Industry.
