The Spotted Lantern Fly (SLF) originates from China, where its presence has been documented in detail dating as far back as the 12th century. In modern times, it was first recorded from a sample collected in Nankin, China. SLF is native to China, India, Japan, Korea and Vietnam. This is attributed to its wide host range (more than 70 host plant species) and a lack of natural native enemies.
In February, the Virginia Department of Agriculture and Consumer Services (VDACS) announced the detection of a new invasive insect pest in Virginia. In early January, VDACS inspectors discovered the Spotted Lantern Fly, lycorma delicatula, at a stone yard in Frederick County near Winchester. Prior to the January detection, the Spotted Lantern Fly was not known to occur in Virginia. Both SLF egg masses and dead adults were detected at the Winchester site.
Spotted Lantern Fly feeds on more than 70 plants, including grapes, stone fruits, hops and ailanthus (Tree of Heaven). The insect causes damage to plants because of its method of feeding, the rapid buildup of large populations and the production of honeydew, a by-product of their feeding activity that serves as a medium for fungal growth. SLF can also be a nuisance pest to homeowners when found in large numbers.
The first U.S. detection of SLF occurred in 2014 at a Pennsylvania business that imports stone products. Stone products from that business went to the Winchester site. VDACS inspectors had been monitoring the Winchester site since 2015, with no positive detections until a routine follow up survey in January. Inspectors then found SLF on ailanthus trees on the property.
Early detection is vital for the management of any newly introduced plant pest. VDACS is now conducting a survey in the surrounding area in an effort to determine the extent of the infestation. VDACS is also working with Virginia Cooperative Extension and the Pennsylvania Department of Agriculture to determine management and control strategies for SLF.
It is highly invasive and can spread rapidly when introduced to new areas. This is attributed to its wide host range (more than 70 host plant species) and a lack of natural native enemies.
At this point, no SLF have been reported in our area; however, it is important to note the locations that it has been spotted. If you plan on purchasing materials from those areas or traveling in those areas, take precautions to not give them a ride back to your home.
