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

The common names for some insects are under review internationally. Spongy moth is the new common name for Lymantria dispar dispar, previously known as European gypsy moth, EGM or LDD moth. This change does not affect the French name.

The common name for the group of moths (Lymantria dispar asiatica, Lymantria dispar japonica, Lymantria umbrosa, Lymantria postalba and Lymantria albescens) referred to as AGM (formerly Asian gypsy moth) has changed to Flighted Spongy Moth Complex (FSMC).


This list includes quarantine or regulated non-quarantine pests. Regulated 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.
