SPOTTED LANTERNFLY

  Spotted lanternfly (Lycorma delicatula)

 

The spotted lanternfly (Lycorma delicatula) is an invasive species that can cause considerable damage to plants, especially to vineyards and other fruit trees (1). Whilst the immature stages (nymphs) feed on a wide range of hosts, the adults prefer the tree of heaven (Ailanthus altissima). When the spotted lanternflies eat, they excrete a sugary substance, called honeydew, which encourages the growth of black sooty mold (2). The sooty mold can stunt plant growth by coating the leaves to the point that it impairs photosynthesis.

Commercial transportation of fruit and timber products is believed to be the cause of the rapid, worldwide spread of the pest (1). The spotted lanternfly is native to Asia (4). It was first detected in an isolated area in Berks County, Pennsylvania in 2014 (6). Despite persistent quarantine efforts, it has since rapidly spread to Delaware, Maryland, New Jersey, Ohio, Virginia, and West Virginia (5). 

 

The spotted lanternfly was first found in Winchester, Virginia in 2018 (4). Soon after it was detected, the Virginia Cooperative Extension began monitoring the spread with the help of the Master Gardeners Association. Recently, I signed up to be a citizen scientist  to help monitor the spread of this invasive species. I installed a trap on a tree of heaven located near the South River. So far I have not detected any spotted lanternflies. However, this data is just as important because it helps scientists know where they have not spread yet. With these observations, conservationists can map the spread and come up with sustainable pest management strategies for Virginia.
