On May 26 Beth Sastre, Commercial Horticulturist from the Virginia Cooperative Extension Loudoun Office, discussed how we can slow the spread of Spotted Lanternfly (SLF), an invasive insect that is spreading rapidly in Virginia. Beth emphasized how to identify SLF in all its life stages, how SLF moves around and hitchhikes, the SLF’s typical lifecycle, and their favorite trees and plants, including Tree of Heaven (Ailanthus Altissima), wild and cultivated grapes, Black Walnuts and Maples, as well as many other plants. SLF can weaken trees and plants, reduce photosynthesis and carbohydrate storage. SLF can also be a human nuisance even though they do not sting or bite. Beth also emphasized integrated pest management; including cultural, mechanical, and chemical controls. A full range of controls will be needed to help slow the spread of SLF.
