The Virginia Department of Agriculture and Consumer Services (VDACS) has detected the presence of the box tree moth, Cydalima perspectalis, in Frederick County. This follows earlier discoveries and treatments of the invasive insect in Clarke and Loudoun Counties during July.
According to VDACS, the box tree moth is an invasive pest that poses a threat to boxwood plants (Buxus species). The insect, which originates from East Asia, has become problematic in Europe as well. Its caterpillars are known for their ability to defoliate host plants rapidly, potentially killing them if infestations are not managed.
“Early detection and rapid response are vital for the management of any newly introduced invasive pest,” VDACS stated. The agency is continuing its surveys to determine how widespread the infestation is and plans further monitoring in affected areas.
VDACS will provide treatment for boxwood plants if the presence of box tree moth is confirmed. Property owners are encouraged to report suspected damage using VDACS’ Invasive Species Reporting Tool.
