The effect of host plant on Lycorma delicatula nymphal development

Lycorma delicatula (White) is an invasive planthopper from Asia that was first introduced to North America in 2014. Despite having a broad host range, it is heavily associated with Ailanthus altissima (Miller). Due to its polyphagous nature, it is important to look at the effect that host plant has on its phenology. Second through fourth instar L. delicatula nymphs was reared on the following hosts at 25°C: Acer rubrum (L.), A. altissima, Salix babylonica (L.), and Vitis labrusca (L.). The development rate and weight was compared for each host. It was found than third instar L. delicatula nymphs took longer to develop on S. babylonica than A. altissima or V. labrusca. Females weighed more and took longer to develop than males in the third and fourth instars.
