What's Happening?
The Virginia Department of Agriculture and Consumer Services (VDACS) has announced a quarantine in Clarke and Frederick counties and the City of Winchester to combat the spread of the invasive box tree moth. This pest, native to East Asia, poses a significant
threat to boxwood plants as its caterpillars can strip plants of their leaves, potentially killing them. First detected in the U.S. in New York in 2021, the moth has continued to spread despite treatment efforts. The quarantine aims to slow the moth's movement by restricting the transport of boxwood plants from quarantined areas unless a permit or compliance agreement is obtained. These agreements allow businesses to self-certify plants by inspecting for the moth, monitoring traps, applying treatments, and notifying recipients when shipping outside the quarantine zone.
Why It's Important?
The quarantine is crucial in protecting the horticultural industry and local ecosystems from the destructive impact of the box tree moth. Boxwood plants are a significant part of the ornamental plant industry, and their destruction could lead to economic losses for nurseries and landscapers. Additionally, the spread of this invasive species could disrupt local ecosystems, leading to further environmental challenges. The quarantine measures are a proactive step to prevent the moth from establishing itself in new areas, which could have long-term ecological and economic consequences.
What's Next?
Residents and businesses in the affected areas are encouraged to report any suspected box tree moth damage using VDACS’ Invasive Species Reporting Tool. The VDACS Office of Plant Industry Services will continue to monitor the situation and provide updates. Businesses involved in the transport of boxwood plants will need to comply with the quarantine regulations to prevent further spread. Ongoing surveys and treatments will be conducted to manage the moth population and assess the effectiveness of the quarantine measures.
