Predicted Diamondback Moth Development Storymap

The Predicted Diamondback Moth Development storymap provides an estimate of the number of potential generations of diamondback moth (Plutella xylostella) expected to occur based on a) the first detection of adult moths in pheromone traps, and b) abiotic conditions. Although the diamondback moth occurs each year throughout the Canadian prairies and north central United States, the severity of the infestation varies considerably from between years and by location. Severity of infestation tends to be driven by local growing conditions and the amount of damage observed is highly correlated with the number of generations and subsequent population growth.

These maps and datasets provide an estimation of risk to oilseed crops due to diamondback moth across Western Canada, where risk may increase as the number of generations of diamondback moth increases. This information, coupled with detections in pheromone traps on a regional basis can be used to time scouting activities in the field.
