Early detection of invasive insect species

Many of Canada’s economically important species of insect pests originated as invasive species that managed to relocate and establish self-sustaining populations. Over time, they became increasingly widespread and so frequently abundant that they became part of the annual list of species we monitor and attempt to manage.

Examples of invasive species that now exist as part of our field crop landscape include wheat midge, cereal leaf beetle, cabbage seedpod weevil, pea leaf weevil, swede midge – in fact, the list of invasive species is far longer! It’s important to consider the impact of invasive species AND recognize that a growing list of species will likely affect field crops in Canada. Globalization, adaptation, and the development of new cultivars suited to Canada’s growing regions, climate change, plus many other factors will contribute to the reality: we can expect more invasive species to continue to arrive.

Where can you play a role??? Early detection and accurate identification are key steps involved in mitigating the risks associated with new invasive species. Many levels of government are active in the ongoing battle against invasive species. Even so, initial detections often arise from keen in-field scouting by producers or agrologists so access these resources to help identify the “that’s weird” or “I haven’t seen that before”. And be sure to thank the many entomologists – regional, provincial, federal, and some amazing amateurs PLUS the folks at Canadian Food Inspection Agency (CFIA) who ALL work to stand on guard for thee!

Canadian Food Inspection Agency’s (CFIA) main Plant Health section can be accessed here.

• More specifically, CFIA’s Plant Pests and Invasive Species information is accessible here.

• Did you know…. CFIA’s top field crop invasive species include anything falling under the List of Pests Regulated by Canada which is accessible here. Caveats are that (i) some species may be on the list (e.g., codling moth) that are not necessarily a high priority but remain to maintain regulatory policy or (ii) list may include species yet to be removed.

• Anyone can access diagnostic information for invasive species at CFIA’s Plant Pest Surveillance section accessible here.

HERE’S WHERE YOU CAN HELP – Experienced producers and agrologists make important discoveries every day! Keep Canadian agriculture strong and support the detection of invasive species using this important information and the three options when encountering unusual damage symptoms or unknown insect species:

Important details to be ready to report: Be ready to include details to make a “report” – Sightings need to be validated so providing as much detail as possible will help the expert confirm identifications and relocate the site, if the issue demands urgent attention.
◦ Date of observation
◦ Nearest town and province
◦ Latitude x longitude values
◦ Host plant(s)
◦ Good photo(s) – lateral, dorsal, damage symptoms, host plant, etc., with some sort of size reference is ideal
◦ Chronological photos (i.e., that tell the story of detection and how and when symptoms or specimen came to your attention)
◦ A specimen may be needed by your provincial entomologist or CFIA

Option 1: Contact your provincial entomologist to confirm identifications and details – they are able to help and historically have acted to triage reports then direct relevant information to CFIA counterparts:
◦ Manitoba (John.Gavloski@gov.mb.ca )
◦ Saskatchewan (james.tansey@gov.sk.ca)
◦ Alberta (shelley.barkley@gov.ab.ca)

Option 2: Alternatively, reports can be sent directly using one of the following paths:
◦ Using CFIA’s Report A Pest website form
◦ Contact a local CFIA office
◦ Or contact CFIA’S general surveillance account email at cfia.surveillance-surveillance.acia@canada.ca
◦ Or contact CFIA’s Survey Biologist for the Western Area (david.holden@canada.ca)

Option 3: Another alternative is to consider documenting your query using iNaturalist.ca (read more here). The basic steps involved are:
◦ Create an account at iNaturalist.ca (https://inaturalist.ca/signup)
◦ Watch your Inbox for a basic how-to guide.
◦ Upload photos or videos (e.g., bird calls) to create an “Observation”
◦ iNaturalist subscribers considered to be experts will help identify your observation.

Weather synopsis

An abbreviated synopsis is provided for the final Weekly Update of the 2020 growing season. It was a warm week for most of the prairies! The highest temperatures the past seven days across the prairies are represented in Figure 1 and ranged from <22 to >35 °C.

Figure 1. Highest temperatures (°C) observed across the Canadian prairies the past seven days (April 1-August 19, 2020).

So far this growing season, the number of days above 25 °C ranges from 0-10 days in the northwest of the prairies then increases up to 61-70 days in southern Manitoba (Fig. 4). In comparison, the number of days above 30 °C ranges up to 25-27 days in southern Saskatchewan and southern Manitoba (Fig. 5)

Diamondback moth

Once diamondback moth is present in the area, it is important to monitor individual canola fields for larvae.  Warm growing conditions can quickly translate into multiple generations in a very short period!

Wind Trajectory Updates – Completed for 2020 growing season as of Week 09 (released June 22, 2020).

Weekly Pheromone-baited Trapping Results – Early season detection of diamondback moth is improved through the use of pheromone-baited delta traps deployed in fields across the Canadian prairies.  Click each province to access moth reporting numbers observed in AlbertaSaskatchewan and Manitoba as they become available. Check these sites to assess cumulative counts and relative risk in your geographic region.

Monitoring: Remove the plants in an area measuring 0.1 m² (about 12″ square), beat them on to a clean surface and count the number of larvae (Fig. 1) dislodged from the plant. Repeat this procedure at least in five locations in the field to get an accurate count.

Figure 1. Diamondback larva measuring ~8 mm long.Note brown head capsule and forked appearance of prolegs on posterior.
Figure 2. Diamondback moth pupa within silken cocoon.

Economic threshold for diamondback moth in canola at the advanced pod stage is 20 to 30 larvae/ 0.1  (approximately 2-3 larvae per plant).  Economic thresholds for canola or mustard in the early flowering stage are not available. However, insecticide applications are likely required at larval densities of 10 to 15 larvae/ 0.1 m² (approximately 1-2 larvae per plant).

2018 Swede Midge Pheromone Monitoring Results

In 2018, swede midge pheromone traps were deployed at 41 sites across the Prairie region of Canada to monitor adult populations of this brassica pest. Of the 41 trap sites, 16 were located in Alberta, 19 in Saskatchewan (where positive swede midge identifications were made in 2007 and 2009), and 6 in Manitoba.

None of the traps were positive for swede midge in 2018. 

We are grateful to all of the producers, agronomists, and cooperators who participated in the 2018 swede midge monitoring project. Without your assistance, we could not have supported such a thorough and widespread pheromone monitoring program.

We also extend our thanks to Jonathon Williams for organizing the program, distributing trapping materials, and processing returned sticky cards for adult swede midge.

Because of the serious threat that swede midge poses to canola production, it is vital that monitoring for swede midge continues across the Prairies. At this time, plans are being made for the 2019 swede midge monitoring program. We hope that we can count on your support and cooperation in 2019.

At this time, plans are being made for the 2019 swede midge monitoring program. Agrologists or growers interested in performing weekly monitoring in 2019 are encouraged to contact Jonathon Williams, Boyd Mori, or Meghan Vankosky for more information.

Wireworm distribution map

Reminder – Last week turned out to be our wireworm blitz!  This complicated group of insect species was featured in the Insect of the Week AND we include the survey results again this week!

The following maps summarize the main results of a survey of pest species of wireworms of the Canadian Prairie Provinces.  Samples (both larvae and beetles) were submitted to Dr. Bob Vernon’s lab in Agassiz, BC, from 2004 to 2017, and identified by Dr. Wim van Herk (Fig. 1).  Species identifications were confirmed with barcoding.

Figure 1.  Sampling locations for click beetles and wireworm larvae (Coleoptera: Elateridae) submitted for wireworm surveying from 2004-2017.

Approximately 600 samples were submitted, with the number of larvae per sample typically less than five (Fig. 1).  More samples are welcome, particularly from areas currently not well represented on the maps.  Please provide either the legal land description or latitude and longitude coordinates with a sample.  Any information on the cropping history or whether fields were irrigated is helpful.

Review the complete survey summary posted in Week 05 (for Jun 7, 2018).

Wireworm distribution map

The following maps summarize the main results of a survey of pest species of wireworms of the Canadian Prairie Provinces.  Samples (both larvae and beetles) were submitted to Dr. Bob Vernon’s lab in Agassiz, BC, from 2004 to 2017, and identified by Dr. Wim van Herk (Fig. 1).  Species identifications were confirmed with barcoding.

Figure 1.  Sampling locations for click beetles and wireworm larvae (Coleoptera: Elateridae) submitted for wireworm surveying from 2004-2017.

Approximately 600 samples were submitted, with the number of larvae per sample typically less than five (Fig. 1).  More samples are welcome, particularly from areas currently not well represented on the maps.  Please provide either the legal land description or latitude and longitude coordinates with a sample.  Any information on the cropping history or whether fields were irrigated is helpful.

The main findings of this survey are that:
1. Wireworms are re-emerging as primary pests of cereals and other crops, particularly in southern Alberta and Saskatchewan.  This can be attributed to several factors, including changes in seeding and cultivation resulting in higher soil moisture and increased food availability, and therefore greater wireworm survival; the elimination of effective insecticides such as lindane and the decline of organochlorine residues in the soil; and the present lack of insecticides that actually kill wireworms.

2. Limonius californicus is generally the predominant pest species in fields reporting heavy wireworm damage, occasionally building up to very high populations and resulting in complete crop wrecks (Fig. 2).  This was not the case when Glen et al. (1943) or Doane (1977) conducted their surveys; L. californicus was considered a minor species at those times.  Selatosomus destructor (Fig. 3) and Hypnoidus bicolor (Fig. 4) are still the most common species.  The pest status of another commonly found species, the predaceous Aeolus mellillus (Fig. 5), is unclear.  The following species listed by Glen et al. (1943) as pests of agriculture in the Prairie Provinces were found also, but infrequently: Agriotes mancusA. criddleiA. stabilisHemicrepidius memnoniusL. pectoralis, and various Dalopius sp.

Figure 5. Distribution of Aeolus mellillus (Coleoptera: Elateridae) submitted for wireworm surveying from 2004-2017.

3. Multiple pest species are frequently found in the same fields where damage is reported (i.e. about 25% of the time, despite the small number of larvae per sample).  This is particularly important as pest species can vary considerably in the type of damage they cause (e.g. it remains unclear if H. bicolor is damaging to potato), their life history (e.g. duration of the larval stage), and susceptibility to insecticides.

Details related to the biology and management of these species are reviewed in van Herk and Vernon (2014) and Vernon and van Herk (2013).

2017 Swede Midge Pheromone Monitoring Results

In 2017, swede midge pheromone traps were deployed at 46 sites across the Prairie region to monitor for populations of this brassica pest. Of the 46 trap sites, two were located in BC, 19 in Alberta, 16 in Saskatchewan, and nine in Manitoba. Figure 1 illustrates trap site locations in 2017. Two pheromone traps were deployed at each site.


All of the traps were negative for swede midge in 2017.

We are grateful to all of the producers, agronomists, and cooperators who participated in the 2017 swede midge monitoring project. Without your assistance, we could not have supported such a thorough and widespread pheromone monitoring program.


We also extend our thanks to Nancy Melnychuk (AAFC-Saskatoon) for organizing the program and distributing trapping materials, and to Jonathon Williams and Shane Hladun (AAFC-Saskatoon) for examining the returned sticky cards.


Because of the serious threat that swede midge poses to canola production, it is vital that monitoring continues across the Prairies. At this time, plans are being made for the 2018 swede midge monitoring program. Agrologists or growers interested in performing weekly monitoring in 2018 are encouraged to contact Jonathon Williams, Boyd Mori, or Meghan Vankosky for more information.

Weekly Update – Cutworms

Cutworms (Noctuidae) – Reminder – Keep an eye on fields that are “slow” to emerge, are missing rows, include wilting or yellowing plants, have bare patches, or appear highly attractive to birds – these are areas warranting a closer look.  Plan to follow-up by walking these areas later in the day when some cutworm species move above-ground to feed.  Start to dig below the soil surface (1-5 cm deep) near the base of a symptomatic plant or the adjacent healthy plant.  If the plant is well-established, check within the crown in addition to the adjacent soil.  The culprits could be wireworms or cutworms.  

Several species of cutworms  can be present in fields.  They range in colour from shiny opaque, to tan, to brownish-red with chevron patterning.  Cutworm biology, species information, plus monitoring recommendations are available in the Prairie Pest Monitoring Network’s Cutworm Monitoring Protocol.  Also refer to Manitoba Agriculture and Rural Initiatives cutworm fact sheet which includes action and economic thresholds for cutworms in several crops. 

More information about cutworms can be found by accessing the pages from the new “Field Crop and Forage Pests and their Natural Enemies in Western Canada: Identification and Field Guide”.  View an excerpt of ONLY the Cutworm pages from the new “Field Crop and Forage Pests and their Natural Enemies in Western Canada: Identification and management field guide”.  The guide is available as a free downloadable document as both an English-enhanced or French-enhanced version.


For Manitobans….Last week’s Insect Update includes great photos of dingy and redbacked cutworms plus monitoring tips which include how to discern these two species from one another.


For Saskatchewanians….Cutworms have been reported in several areas of the Province this spring. Affected crops include pea, lentil, barley and canola. If damage is significant and re-seeding is an option, seed first then spray an insecticide registered for cutworms in the applicable crop. Recommended economic thresholds for cutworms are:
   – 25 to 30 per cent stand reduction (canola)
   – 3 to 6 cutworms / square metre (wheat, barley, oats)
   – 2 to 3 cutworms / sq. metre (pea, lentil)
   – 4 to 5 / sq. metre (flax)

For Albertans….. Cutworms have been reported throughout the province the past week!  If you find cutworms, please consider using the Alberta Pest Surveillance Network’s “2016 Cutworm Reporting Tool”.  Once data entry occurs, your growers can view the live 2016 cutworm map.  A screen shot of the live map has been retrieved (01Jun2016) below for your reference and this week it includes additional reporting sites!

Ongoing Monitoring Efforts for 2015

In 2014, the PPMN compiled data for the following sites highlighted in the map below.  The monitoring data collected from these sites forms invaluable sources of information both now and into the future.

Agricultural people from federal, provincial, regional and industry sectors all contribute to this tremendous effort!  Monitoring at sites like these below provides crucial information on insect pest risk before and during the growing season.  Some sites are visited annually while others are checked weekly and all that data enables the synthesis and generation of risk and forecast maps like those posted here.

THANK YOU to all who contribute!
Please contact Dr. Owen Olfert at AAFC-Saskatoon for more information about this map.
