Season-long effects of spotted lanternfly infestation on young apple and peach trees

Lycorma delicatula, commonly called spotted lanternfly, is an invasive fulgorid, native to China, India, and Vietnam. It was first detected in the US in Pennsylvania in 2014 and has since spread across mid-Atlantic states. Lycorma delicatula is a phloem feeder, and feeding of persistent populations can cause wilt and dieback in host plants. Vineyards in infested regions have already experienced vine loss, where damage has been attributed to L. delicatula. Nymphal and adult lifestages have been observed on cultivated apple and peach trees, however the effect of this pest on these crops has not been quantified. Here we caged young potted apple and peach trees and infested them with 50 L. delicatula per plant for three months and tracked plant health. Horticultural measurements of trunk diameter, height, leaf drop, and photosynthesis rates were recorded before, during, and after infestation.
