Prevention is the most effective way for the Canadian Food Inspection Agency (CFIA) to protect the plant resource base. However should a pest become introduced in Canada, the Agency's goal is to reduce its impact.

The following factsheets have been developed to promote public awareness and encourage reporting of suspect sightings of these species that have the potential to be invasive in Canada, some of which are regulated under the Plant Protection Act. For the full list of regulated pests, visit the Pests regulated by Canada page.

Changes to common names for European gypsy moth and Asian gypsy moth

The common names for the European gypsy moth (EGM) and the Asian gypsy moth (AGM), and other similarly named insects, are currently under review internationally and within Canada, including by the Canadian Food Inspection Agency (CFIA). For now, the CFIA will refer to the EGM as the LDD moth or by its scientific name, Lymantria dispar dispar. The group of moths making up the AGM complex will be referred to by their scientific names, Lymantria dispar asiatica, Lymantria dispar japonica, Lymantria umbrosa, Lymantria postalba and Lymantria albescens, or the short form AGM moth until a final decision on a new common name is made.


This list includes quarantine or regulated non-quarantine pests. Regulated non-quarantine pests may already be established in specific areas of Canada. Contact the CFIA if a pest is found in an area where it is not known to occur.

Under consideration

A decision to regulate these pests is under consideration by the CFIA. Contact the CFIA if these pests are suspected outside their established range.

Additional plant pests and disease information

The CFIA has determined that this does not meet the definition of a quarantine pest. Contact your local provincial authorities if a pest is found in an area where it is not known to occur.
