Welcome to the Sterile Insect Release Program

The Sterile Insect Release (SIR) Program is an area-wide and environmentally friendly approach to managing the codling moth, one of the BC tree fruit industry's most damaging and costly pests.  The SIR Program operates in the fruit growing areas of the Okanagan, Similkameen and Shuswap Valleys, where the tree fruit industry plays an important role in the lives of residents and commercial growers.




 (Updated June 22, 2015)

The OKSIR Board has adopted a Strategic Plan.

OKSIR Program receives International Award of Excellence for integrated pest management.

2015 Neighbourhood Maps and 2014 Apple Clearwing Survey maps are available here.

2015 Codling Moth Trap Counts are available on our interactive Mapping Application. If you would like your trap counts emailed to you each week, please contact us!

A Benefit-cost Analysis of the Okanagan Kootenay Sterile Insect Release Program final report is now available through the Okanagan College Library here.
