The Predicted Bertha Armyworm Development storymap provides weekly predicted stages of development of bertha armyworm (Mamestra configurata) for locations across Western Canada. The bertha armyworm is one of the most significant insect pests of canola in Canada. It occurs throughout Manitoba, Saskatchewan, Alberta and the interior of British Columbia. Severe infestations can occur throughout most of this area but are usually limited to the parkland area of the prairies and the Peace River region of British Columbia and Alberta.

These maps and datasets provide an estimation of the developmental stage of the bertha armyworm across Western Canada in order to equip producers with information on what may be occurring in their area. Information can be used to time scouting activities in the field.

Bonjour Benoit,

Agriculture et Agroalimentaire Canada a fourni la réponse ci-dessous à votre question :

« La légionnaire bertha, Mamestra configurata, est originaire de l’Amérique du Nord. Sa distribution semble être limitée à l’ouest du Canada (c.-à-d. l’intérieur de la Colombie-Britannique, l’Alberta, la Saskatchewan, et le Manitoba). La chercheuse en entomologie n’a pas trouvé de cas de la légionnaire bertha au Québec ou en Ontario. Elle se trouve également dans certaines régions des Grandes Plaines aux États-Unis, avec les cas les plus à l'est étant enregistrés dans le Dakota du Nord. Une liste de cas enregistrés est disponible sur le site Web https://www.cabi.org/isc/datasheet/8492#todistributionDatabaseTable (en anglais seulement).

 

Un autre site Web avec de bonnes informations concernant la distribution de la légionnaire bertha en français est celui du GBIF (Global Biodiversity Information Facility, ou le Système mondial d’information sur la biodiversité) : https://www.gbif.org/fr/species/1788485. »

Bien à vous,

Sam, de l'équipe du Gouvernement ouvert
