12/1/2023 0 Comments Spotted lantern fly tree damageWakie collaborated with USDA-ARS colleagues Lisa Neven, Ph.D., and Wee Yee, Ph.D., and Zhaozhi Lu, Ph.D., of the Xinjiang Institute of Ecology and Geography in China to model suitable habitat for L. Our lab unit at Wapato has a history of conducting invasive species establishment risk studies.” “Due to this, our lab is always on the alert for newly arriving invasive pests. “The potential economic impact of newly arriving pests in Washington is huge,” Wakie says. Despite being far removed from the spotted lanternfly’s current ranges, its ability to spread makes it a serious concern for Washington’s multibillion-dollar apple, cherry, grape, and hops industries. Wakie is based at the USDA-ARS Temperate Tree Fruit and Vegetable Research Unit in Wapato, Washington. The egg masses resemble clumps of mud, making them well-suited to escaping detection and potentially hitching a ride to new locales on transported materials. Lycorma delicatula is not a fly but a kind of insect called a planthopper, and females lay eggs in masses on tree trunks, branches, rocks, or even walls or fences. While its preferred host is tree of heaven ( Ailanthus altissima), the spotted lanternfly has been reported to attack more than 70 plant species, including grapes, apples, cherries, and several other fruit and timber tree species. The spotted lanternfly ( Lycorma delicatula) arrived in Pennsylvania in 2014 and has quickly become one of the top insect pests of concern there and in neighboring states. and Pacific Northwest are vulnerable to establishment of the spotted lanternfly if it finds its way there. A new habitat-modeling study shows most of New England and the mid-Atlantic states as well as parts of the central U.S. “Early detection is key to control and eradication.” “Locations with high risk of spotted lanternfly establishment should consider taking preventive measures,” Wakie says. ![]() Globally, they also found suitable habitat in much of Europe plus parts of eastern Asia and the southern reaches of Africa, Australia, and South America. ![]() Their results, published today in the Journal of Economic Entomology, show that the spotted lanternfly could become established in most of New England and the mid-Atlantic states as well as parts of the central U.S. ![]() Tewodros Wakie, Ph.D., research ecologist at the USDA Agricultural Research Service (ARS), led a team in studying climate data from the spotted lanternfly’s native range in Asia and areas it has invaded in Pennsylvania and New Jersey, and they compared that information with climate data for other global regions to model likely suitable habitat for the insect. Department of Agriculture may not put those minds at ease, as findings show large swaths of the United States and beyond are likely to be vulnerable should the spotted lanternfly continue to spread. 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. 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.
