Box Tree Moth (BTM) Webinar
Jennifer Gray • August 2, 2021
Box tree moth (Cydalima perspectalis) is considered a high-consequence defoliating pest of boxwood, with other possible hosts. Box tree moth (BTM) is a Eurasian native moth. The larvae are voracious defoliators of Buxus.
The pest is established in western Europe, where it has been extremely damaging to boxwood in the landscape. Roughly two years ago, it was found in an urban Toronto neighborhood. In May 2021, the Canadian Food Inspection Agency (CFIA) confirmed the presence of box tree moth (Cydalima perspectalis) in a St. Catharines, Ontario, Canada nursery. On May 26, USDA imposed a federal order prohibiting the importation of all Buxus, Ilex, and Euonymus spp.plants from anywhere in Canada until further notice.
