Figure 2 - Current climate limiting factors

This map depicts the factors that limit the survival rate of the blueberry maggot within the climate range. The limiting factors are the following:

• In the U.S south and the south of Québec and Ontario, maximum temperature during the driest months is a limiting factor. This region of the U.S. includes most of the blueberry maggot sites.
• Along the north and south shore of the St. Lawrence River, the temperature seasonality, the temperature annual range and the isothermality are limiting factors.
• La Route Bleue region is outside of the suitable climate range for the pest.
