Introduction
Spotted lanternfly, SLF, Lycorma delicatula, a sap feeding insect native to Taiwan and China, was first detected in the U.S. in 2014. Field populations continue to expand beyond the 14 county area currently under quarantine in southeastern Pennsylvania. Severe impacts by this insect have been noted.
The current control measure being employed by state and federal cooperators against SLF is a bark spray application of dinotefuran on tree of heaven (Ailanthus), the preferred host tree. The effectiveness of this control approach is readily apparent, especially later in the year when dead SLF adults can be found piled at the base of treated trees (Fig 1). Read Full Report Here
