Diamond back moth is primarily a pest of canola in western Canada but in other parts of the world it is also a serious pest of various crops in the mustard family. Diamond back moth rarely overwinters in western Canada so major outbreaks are often the result of migrations from United States and warm dry conditions that allow multiple generations to develop.

In order to assess the population, a network of 25 monitoring sites has been established across Alberta. This network is meant to act as part of an early warning system for diamond back moth and should be used in conjunction with crop scouting.

The color coding on the map refers to the number of adult moths caught in the past three weeks. The color of the balloon indicates the number of moths caught in that three week period. As the number of moths caught increases it is important to increase field scouting for this insect.

For further information you can click on any balloon to see actual moth counts, county where the traps are located and participating organization for each trap location.
