The effect of host plant on the nymphal development of spotted lanternfly

Abstract

Lycorma delicatula (White) (spotted lanternfly [SLF]), an invasive planthopper from Asia, is an emerging pest in North America. Good phenology models based on the responses of SLF to a broad range of temperatures are needed for predicting when monitoring for SLF needs to be done, when the right stage is present for application of control methods, and what regions of the US are likely to support SLF populations. This information is also needed to develop protocols for rearing large numbers of SLF for use in bioassays or biological control rearing. Without an efficient laboratory rearing methodology for SLF, mass rearing of any discovered natural enemies needed for field testing or release will be limited, especially outside the infested zone. Efforts to screen pesticides are equally restricted by the resources needed to obtain the large numbers of even aged individuals from natural populations. Year-round mass rearing would allow rapid screening of many pesticides and other monitoring or control methods.
