USDA APHIS has developed a draft assessment to determine the hosts of box tree moth (Cydalima perspectalis). On May 26, 2021, APHIS issued a Federal Order amending the entry requirements for the importation of boxwood (Buxus spp.), Euonymus spp., and holly (Ilex spp.) plants for planting from Canada to prevent introduction of box tree moth into the United States. The purpose of this assessment is to critically examine associations of the box tree moth with non-Buxus plants reported in the literature. This document will be used to update restrictions for nursery plants that could serve as pathway of introduction for box tree moth.

APHIS is sharing the draft assessment to determine whether stakeholders have information that might lead us to revise the assessment before we update our requirements for hosts of box tree moth.

The draft assessment will be available for review and comment until April 6, 2023. To view the assessment or submit comments, go to https://www.aphis.usda.gov/plant-health/risk-assessment-consultation.
