Thirty years of results in British Columbia.

The Okanagan-Kootenay Sterile Insect Release program has run area-wide sterile insect release since the 1990s. Wild captures are down more than 92 percent and pesticide use down 88 to 97 percent since 1991.

Every release uses sterile moths tested for flight performance, emergence rates, and mating competitiveness, so only moths that meet quality thresholds reach an orchard.

Weekly releases, season-long control

Sterile moths seek out the wild ones rather than waiting for them. It works best when adjoining orchards go in together.

A first generation flies May into June, a larger second overlaps it through August, and a variable third follows. Releases repeat weekly for as long as adults are flying, about 20 releases across a season.

Sterile insect release is a layer on top of your existing integrated pest management program. Fruit damage assessment is the definitive measure of success.
