VDACS Announces Detection of Box Tree Moth in Frederick County, Va.

Richmond, Va. - The Virginia Department of Agriculture and Consumer Services (VDACS) announces the detection of the box tree moth, Cydalima perspectalis, in Frederick County, Va. In July, VDACS inspectors discovered and treated the invasive species in Clarke and Loudoun Counties. VDACS will continue to survey to determine the extent of the box tree moth population in these areas.

Box tree moth is an invasive insect pest that can significantly damage and potentially kill boxwood (Buxus species) plants if left unchecked. The box tree moth is native to East Asia and has become a pest in Europe where boxwood is native. The caterpillars are ravenous feeders, and heavy infestations can completely defoliate host plants. VDACS will provide treatment for boxwood plants, if box tree moth is confirmed on boxwood plants.

Early detection and rapid response are vital for the management of any newly introduced invasive pest. VDACS has surveyed the area surrounding the detections to determine the extent of infestation and has planned for more surveys to occur in the future. VDACS encourages property owners to report any suspected damage to boxwood plants on their property by using VDACS' Invasive Species Reporting Tool.
