A new habitat-modeling study from the U.S. (Image originally published in Wakie et al 2019, Journal of Economic Entomology)Īs the invasive spotted lanternfly wreaks havoc in the mid-Atlantic United States, scientists and a range of tree and fruit growers around the world are concerned about where the pest could show up next. and Pacific Northwest are vulnerable to establishment of the spotted lanternfly if it finds its way there. ![]() In the United States, their findings show most of New England and the mid-Atlantic states as well as parts of the central U.S. Department of Agriculture and the Xinjiang Institute of Ecology and Geography in China studied climate data in the host ranges of the spotted lanternfly ( Lycorma delicatula) to model what other locales offer potentially suitable habitat for the invasive insect. Please note: a photo of the suspected pest is required to be submitted with this form.Researchers at the U.S. For more detailed information regarding these options visit PSU Extension webpage. Please be sure to carefully read and adhere to all pesticide products labeled directions for use. Several insecticides have been shown to be effective against nymph and adult SLF. These nymphs will crawl up and down trees to feed each day and can be controlled by banding the trees with an adhesive trap. SLF nymphs will emerge from the egg masses in early May. Egg masses can be removed by scrapping with a hard or rigid tool and disposed of into a container of rubbing alcohol. The egg masses may be laid on any hard surface, including trees, rocks, and outdoor furniture. SLF can feed on more than 100 plant species, and has the potential to greatly impact the viticulture, tree fruit, nursery, and timber industries. In addition, during feeding the SLF secretes honeydew which can buildup on and underneath the plant, which in turn promotes the growth of black sooty mold. The feeding can result in oozing sap, wilting, leaf curling, and dieback. SLF damage is caused by the insect feeding on the trunk and branches of woody plants. Please call 61 for more information about compliance agreements for commercial activities.Ī national map of the reported distribution is available through New York State's IPM website. Nurseries, arborists, loggers and other commercial activities may need to be covered by a compliance agreement in order to ship certain products out of infested counties. Individuals traveling from an SLF infested area with items including tree branches, nursery stock, firewood, logs, or other outdoor items that pose a high risk of spreading the pest are asked to complete a self-inspection checklist. SLF can spread long distances quickly by people who move infested materials or those containing egg masses.Ĭurrently SLF is only known to be established in Cuyahoga, Jefferson and Lorain counties. SLF is now designated a destructive plant pest under Ohio law, which increases inspections and restricts movement of certain items from infested counties in Ohio and other states into non-infested Ohio counties. On October 28th, 2021 the Ohio Department of Agriculture announced a quarantine to combat the spread of the spotted lanternfly. If you suspect a spotted lanternfly infestation, at any life stage, please take a picture or collect a sample and report the finding to the ODA Plant Pest Control using the Ohio Plant Pest Reporter. These adults are larger (approximately 1 inch), with black bodies and brightly colored wings. ![]() During the late summer and autumn, the SLF is in the adult moth stage. During the first three they appear black with white spots, and in the last stage, which typically occurs during mid-summer, they are red with white dots and black stripes. After hatching in late spring, the SLF goes through four nymph stages. The egg masses of the SLF are small, grey masses protected by a waxy covering. SLF will lay eggs beginning in October through the beginning of winter. Black sooty mold around the base of plants or oozing sap may indicate the presence of the spotted lanternfly, however other pests can cause these symptoms as well. ![]()
