The Okanagan-Kootenay Sterile Insect Release Program (SIR) is an environmentally responsible, area-wide approach.
Since the SIR Program began in 1991, there has been a significant reduction in the number of codling moths.
Since the beginning of the SIR Program, wild codling moth populations have been reduced by 94%.
Insect Release Process
Our Program uses Sterile Insect Technique (SIT), producing sterile codling moths and releasing them at regular intervals.
Today the Program’s success is achieved with the participation of four regional district governments.
Mission & Vision
The mission of the Okanagan-Kootenay Sterile Insect Release Program (SIR) is to reduce the use of pesticides.
The codling moth was accidentally introduced into British Columbia from Europe in the early 1900s.
