Abstract

A pair of native fungal pathogens drives decline of a new invasive herbivore.

Abstract

Two North American fungal pathogens caused a coepizootic leading to localized collapse of an outbreak population of the newly invasive planthopper pest, the spotted lanternfly (Lycorma delicatula), in the eastern United States. The pathogens partitioned the habitat, with the majority of L. delicatula on tree trunks killed by Batkoa major, while cadavers of L. delicatula killed by Beauveria bassiana were usually on the ground. The future will show whether these pathogens will be drivers in boom-bust cycles or will result in recurrent low population densities of this new invasive species.
