![]() There is a strong preference for TOH during the 4th instar through early- to mid-staged adults. With no significant preference for TOH, early instar nymphs have a broader host range than adults. Tree of Heaven (TOH) is the preferred, possibly required, host of spotted lanternfly.įeeding behavior varies depending on life stage. Spotted Lanternfly is known to feed on over 70 host plant species! U.S.While the Spotted Lanternfly prefers the Tree of Heaven ( Ailanthus altissima), it feeds on a variety of host plants including fruit trees, ornamental trees, woody trees, vegetables, herbs, grains and vines. Department of Agriculture-National Invasive Species Information Center: Spotted Lanternfly Penn State Extension: free permit training The training is free and is required for all businesses that operate in quarantine zones, but it is available to anyone who is interested. (List is not exhaustive.)Ī comprehensive training guide-focused on SLF identification and behavior, how to safely destroy SLF, and how to implement best practices in areas with SLF-is available through Penn State Extension (first in the list). What training is available?Īlthough SLF has not been observed in any NCA parks, all NPS employees are encouraged to learn about SLF and its management through training and online resources including those listed below. ![]() In addition, the Invasive Plant Management Team (formerly the Exotic Plant Management Team or EPMT) has been selectively treating the exotic clusters of tree-of-heaven ( Ailanthus altissima)-a preferred host species for SLF-in parks closest to quarantined areas to help limit SLF introduction pathways. Most SLF work in NCA so far has focused on education and preventing the introduction of the pest into the area’s parks. ![]() New York State Integrated Pest Management Program What are NCA parks doing? Spotted lanternfly locations and quarantines as of December 2018 Of particular concern are the quarantined areas in Virginia (Frederick County and the City of Winchester) and Maryland (Harford and Cecil counties) as they are within 50 miles of five NCA parks: Catoctin Mountain Park, Antietam National Battlefield, Harpers Ferry National Memorial Park, and the Chesapeake & Ohio Canal National Historical Park. However, there have been several confirmed sightings nearby resulting in quarantines for counties throughout Pennsylvania, Delaware, northern Virginia, New Jersey, and Maryland. To date, Spotted Lanternfly (SLF Lycorma delicatula) has not been observed in any National Capital Area (NCA) parks. It impacts its host directly by extracting plant sap from young leaves and stems using piercing and sucking mouthparts, and causes indirect harm by excreting a sugary liquid (honeydew) that attracts other insects and promotes the proliferation of black sooty mold, which can negatively affect plant growth and initiate secondary fungal infections. ![]() Although SLF has a preference for feeding on the exotic tree-of-heaven (Ailanthus altissima), it is an indiscriminate pest and will feed on over 70 different plant species. Once established in an area, SLF has the potential to dramatically affect forest ecosystems, agricultural production, and cultural resources. So it’s vital that anyone visiting or traveling through a quarantined area is aware of the risks of spreading SLF, and take extra precautions. grills, mowers, furniture) or recreational vehicles. stone, lumber, wood crates), outdoor household articles (e.g. nursery trade), firewood, construction and shipping materials (e.g. People can unknowingly move the inconspicuous egg masses over long distances when moving plants (e.g. Unfortunately, human action is currently the main factor helping spread SLF in the U.S. As a result, SLF does not typically move very far without help. It spreads primarily by hopping (in the juvenile stage) and short-distance flight (in the adult stage)-similar to its close relative, grasshoppers. Despite its name, spotted lanternfly is not a fly it is a planthopper in the order Hemiptera, which also includes true bugs, aphids, and cicadas. Spotted lanternfly (SLF Lycorma delicatula) is an invasive insect native to China, India, and Vietnam. Spotted lanternfly is a new, invasive, insect pest approaching the National Capital Area (NCA).
