Every year, we conduct surveys to support plant health in Canada.
Our Plant Health Survey Program supports plant health by detecting new pests and by monitoring the spread of established pest populations, forming the basis for sound regulatory decisions. Surveillance data collected by trapping, visual inspection and sampling efforts contribute to policy development and trade negotiations. Plant health surveillance activities also support Canada in meeting the International Standards for Phytosanitary Measures.
These survey results were collected between April 1, 2025, to March 31, 2026.
This page will be updated to add the survey results for other pests.

Forest pests
Emerald ash borer
The emerald ash borer (Agrilus planipennis) was first detected in Canada in Windsor, Ontario, in July 2002. Since the initial detection, this species has been found in:
- parts of Ontario, Quebec, New Brunswick and Nova Scotia
- Manitoba: Winnipeg
- British Columbia: Metro Vancouver Regional District
The primary goal of this survey is to determine whether emerald ash borer is present in areas where it is not known to occur to provide information in support of regulatory decisions.
Method: visual inspection and traps
Two main strategies were used for emerald ash borer detection in Canada:
- visual inspection of ash trees
- trapping using green prism traps baited with attractants
In addition, targeted branch sampling was also used in newly infested areas in the Metro Vancouver Regional District. This method increases our ability to detect newly infested trees that do not show signs or symptoms of infestation.
Target sites for this survey include areas showing broad-scale ash decline and high-risk sites where the pest is most likely to have been introduced through human activities, such as:
- campgrounds
- firewood dealers
- rest stops along major transportation corridors
- urban areas recently planted with host material
- sawmills
- holiday destinations
Traps were also deployed within select urban centers using a grid-based approach.

Hemlock woolly adelgid
The hemlock woolly adelgid (Adelges tsugae) is a destructive pest of susceptible species of hemlock (Tsuga spp.). Native to eastern Asia and western North America including British Columbia where it was first reported in 1919. The pest was first detected in the eastern United States in 1951. Since then, it has steadily spread and is now reported from 21 eastern states. In the eastern U.S., it has resulted in significant mortality of both eastern hemlock, (T. canadensis) and Carolina hemlock, (T. caroliniana) and threatens the existence of these 2 species in many locations.
In Canada it has been detected in:
- western Nova Scotia
- southern Ontario
Method: visual inspection
This survey was conducted between November and June to visually assess hemlock trees for signs and symptoms of attack. Given that the pest is most likely to spread through natural dispersal (wind, birds and small mammals) and through infested nursery stock, target sites included:
- nurseries importing hemlock
- urban parks and greenspaces
- hemlock forest stands within 100 km of the U.S. border
- infested counties in Canada
- hemlock forest stands along migratory bird routes

Brown spruce longhorn beetle
The brown spruce longhorn beetle (Tetropium fuscum) an introduced wood boring pest, is native to north and central Europe and Japan, where it uses stressed and dying conifers as hosts, most notably Norway spruce (Picea abies). All species of spruce in Canada are at risk. In 1999, the beetle was detected in Point Pleasant Park, Halifax, Nova Scotia and confirmed to have been present since at least 1990. In 2025, it was detected again in Quebec, in the Beauce-Sartigan regional county municipality. The brown spruce longhorn beetle is considered to be a pest of quarantine significance in Canada and is regulated under the Plant Protection Act by the CFIA. The entire province of Nova Scotia is regulated for this pest.
Method: traps
Panel traps baited with pheromones are used for this survey. Trapping is conducted at 2 types of sites:
- priority sites such as sawmills, pulp mills campgrounds and ports
- general forested areas
This survey is performed in Eastern provinces to prevent further spread from the known infested areas.
Results from 429 sites surveyed
| Provinces | Number of sites surveyed | Results |

Asian longhorned beetle
The Asian longhorned beetle (Anoplophora glabripennis) is an invasive insect that attacks and kills a wide variety of deciduous tree species. This beetle was detected for the first time in Canada in September 2003. An eradication program was implemented and in 2020, the pest was declared eradicated from Canada based on 5 years of negative survey data and in accordance with international phytosanitary standards. Given the constant threat this pest poses to Canada, ongoing national surveillance activities are designed to ensure a high probability of detection in high-risk areas.
Method: visual inspection
This survey is conducted through visual inspection looking for symptoms and signs of attack by this beetle on host trees:
- maple
- willow
- poplar
- birch
- elm
The survey is carried out between September and March when leaves are absent and the bark of branches located in the canopy is visible. An area-wide grid-based approach is implemented in high-risk areas and includes a variety of landscapes:
- residential areas
- commercial areas
- industrial areas
- transportation/utility corridors
- forested land and green spaces

Oak wilt
Oak wilt (Bretziella fagacearum) is a vascular wilt disease that is capable of killing trees in a single season. It was first recognized as an important forest pest in 1944 in Wisconsin and is now known to occur in 24 states within the U.S. In 2023 oak wilt was detected for the first time in Canada, at 3 locations in Ontario. An active management plan was implemented to support eradication of the disease at these locations. Oak wilt is spread from diseased to healthy trees through:
- root grafting
- oak bark beetles
- sap beetles
All oak species are susceptible to oak wilt, but red oaks are more frequently infected and can die quite quickly. The primary goal of this survey is the early detection of the pest in areas where it is not known to occur.
Method: visual inspection
This survey consists of a visual inspection of host trees for signs and symptoms of oak wilt. Surveys focus on areas where oak wilt could have been introduced through human-assisted movement of infected commodities from infested areas. An emphasis is placed on:
- campgrounds where oak firewood may be transported from infected areas
- mills or other facilities importing oak logs
- disposal sites
- areas where recent weather events may have damaged limbs/trees

Red pine scale
The red pine scale (Matsucoccus matsumurae) is a destructive pest of susceptible species of pine that is native to Japan and introduced into China, South Korea, Europe and United States.
It was first reported in North America in 1949 in Connecticut, but has since spread to Maine, Massachusetts, New Hampshire, New Jersey, New York, Pennsylvania and Rhode Island.
Red pine scale kills red pine (Pinus resinosa) trees of all ages within a few years of infestation.
Method: visual inspection
This is a visual survey aimed at early detection of the pest in areas of Canada at risk to introduction. Trees are visually inspected for symptoms and signs of the pest:
- yellow and red foliage
- decline
- bark beetle attack
- cottony white filaments on branches
The optimal period for this survey is from September through October. However, surveys can occur year-round. This survey targets forest stands at risk in urban areas, near importers of pine forest products and nursery stock, and in pine stands located within 100 km of the Canada and U.S. border.

Horticulture pests
Ramorum blight
Ramorum blight (Phytophthora ramorum) is a plant pathogen that causes a disease known as ramorum blight on a wide variety of nursery plants. It has also been associated with a disease of oak, known as "Sudden Oak Death", that was first observed in coastal California in the mid-1990's. Since 2003, ramorum blight has been detected in a number of retail/wholesale nurseries in the southern coastal area of British Columbia. The primary goal of this survey is to provide information on the national status of this disease in Canadian nurseries. Additional surveys are conducted to support eradication activities following a new detection. Sites with detections are also surveyed for 2 years following an eradication in order to confirm the success of the eradication.
Method: visual inspection
The focus of this survey is to visually inspect high-risk host plants at target facilities and to collect samples with symptoms consistent with expression of ramorum blight infection. The survey targets nurseries that propagate the host plants listed in D-01-01: Phytosanitary requirements to prevent the entry and spread of Phytophthora ramorum and nurseries that grow ramorum blight host plants beyond the year of import or propagation, including wholesale nurseries.

Plum pox virus
Plum pox virus (Potyvirus plumpoxi) is a serious plant disease that affects many stone fruit species within the genus Prunus, including:
- peaches
- nectarines
- plums
- apricots
- almonds
- some ornamental varieties
Although it does not kill trees, it:
- reduces the marketability of the fruit
- causes early fruit drop in infected trees
- drastically reduces fruit yields
Plum pox virus is present in parts of the Niagara Region and the City of Hamilton, Ontario, where a regulated area has been established. This survey is being conducted in support of policies and programs related to D-99-07: Policy for importation from the United States and domestic movement of plum pox virus susceptible Prunus propagative plant material.
Method: leaf sampling
Leaf sampling surveys take place at select orchard and residential properties to ensure continued monitoring along the boundary of the plum pox virus regulated area. Depending on the location and site type, these activities are performed on a rotational basis, taking place every 1 to 3 years.
Results from 148 sites surveyed
| Provinces | Number of sites surveyed | Results |

- Nova Scotia
- New Brunswick
- Prince Edward Island
- parts of Ontario
- parts of Quebec
It is not found in Newfoundland and Labrador or in western Canada.
Method: traps
This survey uses baited traps which are attractive to male and female blueberry maggot adult flies. Multiple traps are placed within blueberry plantations and wild sites containing host species in areas not regulated for blueberry maggot. Traps are installed prior to the pest's flight period in late June and collected at the end of harvest or fruit drop, in late August or early September.

Apple maggot
Apple maggot (Rhagoletis pomonella) is an indigenous pest of apples in Canada. The BC Interior is the last major apple growing area of North America free from this pest. The objective of this survey is the early detection of apple maggot to maintain the pest-free area of the BC Interior. This survey is being conducted in support of policies and programs related to CFIA policy directive D-00-07: Phytosanitary requirements to prevent the introduction and spread of apple maggot. In 2015, a single female apple maggot was detected in West Kelowna and in 2016 another single female was detected in the city of Kelowna. Despite increased surveillance from 2016 to 2019 apple maggot has not been detected since 2016.
Method: traps
This survey is conducted using sticky red spheres baited with an attractant and placed in host plants between June and September, when adult apple maggot flies are active. Traps are deployed to give an optimal coverage of known pome fruit production areas and associated urban and rural properties with suitable hosts, as well as riparian areas. The survey also includes selected sites that are perceived to be high risk for introduction of the pest.
Results from 221 surveyed sites
| Provinces | Number of sites surveyed | Results |
|---|---|---|
| British Columbia | 221 |
No new detections in the pest free area and outside the known infested areas. The pest free area in the interior of British Columbia is considered free from apple maggot. |
Map of results
The map shows 221 sites that have been surveyed for apple maggot in British Columbia, Canada, in 2025. The sites are mostly located in the Okanagan valley, around Kamloops and in the Kootenay-Boundary region, in proximity to the U.S.-Canada border.
Japanese beetle
The Japanese beetle (Popillia japonica) has been present in Canada since its first detection in Yarmouth, Nova Scotia, in 1939. This pest affects more than 300 plant species, including many economically important plants such as:
- fruit trees
- ornamental shrubs and roses
- field crops
- turf grasses and sod
In 2017, Japanese beetle was detected in Vancouver, British Columbia and a multi-collaborator eradication program has been ongoing since 2018. In 2025, a total of 2,226 beetles were caught in British Columbia, most of them in Kamloops and Port Coquitlam.
Japanese beetle was detected again in 2025 the City of St. John's, Newfoundland and Labrador. An eradication program was launched by provincial and municipal collaborators to attempt eradication of the beetle from St. John's and prevent further spread in Newfoundland and Labrador.
Method: traps
This survey is conducted using pheromone traps which were installed in May and remained in the field until October. The traps contain a Japanese beetle attractant which is a combination of a floral lure and a pheromone. In the greater Vancouver area, where eradication is in progress, traps are deployed at various densities, with infested municipalities having the highest density of traps. Survey data is then used to inform treatment activities.
For other locations in Canada, traps are placed adjacent to or near importers of sod, soil or nursery stock from Japanese beetle infested areas and include sites such as nurseries, sod farms, golf courses, cemeteries, public parks and gardens, food terminals, truck and rail compounds/terminals, airports and border points.

Tobacco blue mold
Tobacco blue mold (Peronospora hyoscyami f. sp. tabacina) is a serious disease of solanaceous plants including:
- tobacco
- peppers
- tomato
- eggplant
It was reported for the first time in North America in 1921, in the States of Florida and Georgia. In Canada it was first reported in Ontario in 1938. This disease has never been reported from British Columbia. Survey activities for this pest are conducted to confirm British Columbia's pest-free status for the exportation of peppers.
Method: visual inspection
This survey was conducted in cooperation with Agriculture and Agri-Food Canada. Visual surveys were conducted on indicator plants (Tobacco blue mold-sensitive tobacco plants, Nicotiana tabacum) at three sites in southwestern British Columbia.
Results from 3 surveyed sites
| Provinces | Number of sites surveyed | Results |
|---|---|---|
| British Columbia | 3 |
No detections There are no changes to the status of tobacco blue mold in Canada. |
Box tree moth
The CFIA has been leading monitoring efforts for box tree moth (Cydalima perspectalis) working with community scientists and collaborators to deploy traps. Volunteers with boxwood in key areas were recruited via social media and collaborator networks. The 2025 monitoring program focused on gathering data to support British Columbia's pest-free status for box tree moth. Traps were distributed to volunteer community scientists in support of this objective.
Method: Visual inspection and traps
Monitoring kits were comprised of traps with sticky liners, lures, pest detection cards and instructions on how to complete data entry using an online community science platform.
Trapping was conducted between May and late September when adults are actively flying. "Milk carton" traps with trap openings enlarged to enhance trap captures and optimize detection efficacy were used to ensure easy shipping and disposal. Traps were checked weekly for the presence of moths and pheromone lures were changed once in August. Data entry was completed weekly and no suspect moth findings were reported.
Results from 113 sites surveyed

Other pests of concern
Khapra beetle
The Khapra beetle (Trogoderma granarium) is considered one of the world's most destructive pests of grain products. At optimal temperatures, populations can grow at an extremely fast rate leading to damage rates of 30% to 70%. In addition, Khapra beetle found infesting Canadian grain products could severely affect export markets due to phytosanitary restrictions and increased costs of production through additional treatment measures. Canada is considered free from Khapra beetle.
Method: traps
Khapra beetle may be present at any time of the year in protected environments, but they are only active at temperatures above 20°C. Traps were placed in facilities between June 1 to August 31. Facilities selected for this survey were those that had imported commodities originating from countries where the pest is established. Surveillance was focused upon commodities where the pest had been intercepted by Plant Protection inspectors in the U.S., Mexico or Canada in the past five years.
