A crucial battle against codling moth infestations in Okanagan orchards has seen some success, but there's still a long way to go. The Okanagan Sterile Insect Program, a dedicated initiative to protect apple, pear, and fruit growers, has made significant strides in keeping codling moth populations in check. However, their 2025 report reveals a mixed bag of results, falling just short of their ambitious target.
Despite their efforts, the program's board of directors acknowledges that more work is needed. Over half of the orchards have successfully kept codling moths at bay, with an impressive 86% showing extremely low levels of infested fruit. But here's where it gets controversial: the program narrowly missed its goal of achieving less than 0.2% infestation in over 90% of the pome fruit acreage.
The report highlights the complexity of the issue, stating that various factors contributed to the fluctuations in moth damage across different regions. Through the release of sterile insects, the program managed to reduce the number of codling moth traps by 15%, a notable achievement. However, the board emphasizes that the overall decline in moth captures is partly due to the reduced number of traps, with the average catch per trap remaining consistent year over year.
An interesting finding is that the worst 10% of orchards in the program accounted for a staggering 55% of the wild moths captured. This suggests that targeted interventions in these orchards could significantly impact overall moth populations.
The agency overseeing the program remains committed to continuing its work in 2026, targeting both commercial orchards and residential properties with apple and pear trees.
As we delve deeper into this issue, it's evident that while progress has been made, there's still room for improvement. The delicate balance between natural pest control and agricultural protection is a complex challenge, and the Okanagan Sterile Insect Program's ongoing efforts are a testament to that.
What are your thoughts on this ongoing battle against codling moths? Do you think enough is being done to protect our orchards, or is there more we can do as a community? Let's discuss in the comments and explore potential solutions together.
