Predicted diamondback moth development

Diamondback moths (DBM) (Plutella xylostella) are a migratory invasive species. Each spring adult populations migrate northward to the Canadian prairies on wind currents from infested regions in the southern or western U.S.A. Upon arrival to the prairies, migrant diamondback moths begin to reproduce and this results in subsequent non-migrant populations that may have three or […]

Predicted diamondback moth development

Diamondback moths (DBM; Plutella xylostella) are a migratory invasive species. Each spring adult populations migrate northward to the Canadian prairies on wind currents from infested regions in the southern or western U.S.A. Upon arrival to the prairies, migrant diamondback moths begin to reproduce and this results in subsequent non-migrant populations that may have three or […]

Weather synopsis

TEMPERATURE: This past week (May 31 – June 6, 2021) extremely warm conditions resulted in weekly average temperatures that were well above normal (Fig. 1). The warmest temperatures were observed across Manitoba and eastern Saskatchewan (Fig. 1). Across the prairies, the average 30-day (May 8 – June 6) temperature was almost 2.5 °C warmer than […]

Weather synopsis

TEMPERATURE: This past week (May 24-30, 2021) the average temperature across the prairies was 1 °C cooler than normal (Fig. 1). Temperatures were warmest across most of Alberta and coolest across Saskatchewan and central regions of Manitoba. Across the prairies, the average 30-day (May 1-30) temperature was almost 2 °C warmer than last week and […]

Weather synopsis

TEMPERATURE: This past week (May 17-23, 2021) began with hot dry conditions followed by cool/wet conditions (mid-week reports of snow and minimum temperatures less than 0 °C). Most of the prairies had significant rainfall over the weekend. The average temperature across the prairies was 1 °C cooler than normal (Fig. 1). For the second week […]

Weather synopsis

TEMPERATURE: This past week the average temperature across the prairies was 2.5 °C warmer than normal (Fig. 1). Temperatures were warmest across the Parkland region in Manitoba, Saskatchewan, and Alberta. The prairie-wide average 30-day temperature (April 17- May 16) was 0.9 °C less than climate normal values. A region from Winnipeg to Saskatoon has been […]

Weather synopsis

Since April 1, the 2021 growing season has been cooler and dryer than normal. The National Agroclimate Risk Report states that the most significant climate-related risk to agriculture is the dry conditions across the prairie region (access the Spring to April 27, 2021 report). This past week (May 3-9, 2021), the average temperature across the […]

Potential of trajectories for monitoring insect movements

Agriculture and Agri-Food Canada (AAFC) and Environment and Climate Change Canada (ECCC) have been working together to study the potential of trajectories for monitoring insect movements since the late 1990s. Trajectory models are used to deliver an early-warning system for the origin and destination of migratory invasive species, such as diamondback moth. In addition, plant […]

Weekly Update

Seeders are rolling across the prairies this week and we’re back for 2021 with Week 1! In addition to the Weekly Update, be sure to catch the Insect of the Week and Wind Trajectory Report. Now, more than ever, we wish everyone a safe and productive field season! Stay Safe! Questions or problems accessing the […]

Weather synopsis

Since April 1, the 2021 growing season has been cooler and dryer than normal. This past week (April 26-May 2, 2021), the average temperature across the prairies was approximately 0.5 °C cooler than normal. Similarly, the average 30-day temperature (April 3- May 2) was 0.6 °C less than climate normal values. Temperatures have been warmest […]

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 […]

Weekly Update

Greetings! Another busy week of in-field monitoring, data collection, and field tour events for all our Staff!  A reminder that, from now until mid-July, the Weekly Update may need to be posted in multiple segments (i.e., at any point from Wednesday-Saturday).  Please bookmark the Blog or subscribe to receive the latest growing season information! This week, special thanks to […]

Weekly Update – Diamondback moth

May 1 (Fig. 1) AND May 21 (Fig. 3), the predicted number of generations of DBM can be estimated across the Canadian prairies as of July 24, 2017. The following maps indicate that potentially two generations have been completed across most of the prairies for both biofix dates (Fig. 1 and 3).  The second map […]
