Spotted Lanternfly (SLF), Lycorma delicatula, is an invasive planthopper native to Asia that was first introduced into Pennsylvania in 2014 and has since spread to the surrounding states of New Jersey, Delaware, Maryland, Virginia, West Virginia, New York, Connecticut and Ohio. [1]
Though Tree of Heaven, Ailanthus altissima, is the SLF’s preferred host tree, SLF has a very broad host range and has been recorded feeding on over 70 different plant species, including economically important crops and a variety of tree species. In addition to Ailanthus, SLF has been observed to prefer feeding on a variety of trees common to our area including but not limited to walnut, birch, willow, sumac and in particular, red and silver maples. [2]
While SLF feeding can stress plants and cause localized branch damage, it is not known to directly kill trees other than in the case of extreme infestations on Ailanthus trees and black walnut saplings. While SLF is not known to kill trees, it is a plant stressor that in combination with other stressors (e.g., other insects, diseases, weather, etc.) can cause harm to its host. [3]
Jersey City Forestry will continue to monitor trees for SLF infestation and perform pruning and removal of trees if they pose a safety risk to the public. Ailanthus trees will be removed from public properties whenever possible. The public is encouraged to kill SLF when encountered. Egg masses can be found on any smooth surface such as tree bark, stone, metal, etc., throughout the Fall, Winter and into Spring, and can be scraped into a container and neutralized with alcohol. Circle traps can be built or purchased and used throughout the Summer and Fall to trap nymphs and adults. Sticky traps are discouraged as they can trap beneficial insects and animals, including birds, small mammals, pollinators, butterflies, and more. If you have Tree of Heaven on your property, consider removing the tree fully, including its root system, as it can sprout back if roots are left in the ground. [4]
