The SIR program is a service of four participating regional districts: Okanagan Similkameen (RDOS), Central Okanagan (RDCO), North Okanagan (RDNO), and the Columbia Shuswap (CSRD).

Through their SIR establishment bylaws, the regional districts define the program’s structure and activities. The regional districts also advocate on behalf of the program and facilitate the collection of parcel and property value taxes.

Growers are responsible for developing sustainable pest management plans for their orchards – plans that integrate sterile insect release with other measures, as required. Growers cooperate with SIR program staff in insect monitoring and release efforts, and report moth infestations and the presence of unmanaged host trees. Growers support the program through parcel tax payments.

Residential property owners with host trees are responsible for preventing the proliferation and spread of pests, including codling moths. Residential owners must allow access to their property by program staff and control codling moth infestations on their property.

Packinghouses and other fruit handlers assist growers in understanding codling moth biology, and methods (including sterile insect release) to deal with the insect. Fruit handlers are responsible for sanitizing fruit bins and containers.

Retailers may support the program by volunteering to participate in a sterile insect release Host Tree Registry. They advise buyers of the need to prevent infestation, and on the methods of prevention.

Entomologists with both the federal and provincial governments provide technical advice on the rearing and release of sterile insects, as well on future directions for the program.

Local, National and International organizations which the SIR Program has collaborated with include the following groups.
