"Pomegranate Pest Management in SJV" by AAIE members is a helpful guide.
It doesn't mention a pest we've had inquiry about in pomegranates west of Fresno, filbertworm, Cydia latiferreana, relative of codling moth,
with oaks another host. Grower calls it biggest challenge to organic pomegranate production in early variety.
Last season Cedarguard and a neem product were applied too late to be able to evaluate and we are reluctant to recommend them in terms of disrupting beneficials that are apparently controlling all of the key pests reviewed in the paper.
Since Trichogramma is a solid control program for codling moth in organic apples, wouldn't it be worth exploring an organic program that includes Trichogramma platneri releases combined with habitat enhancement to attract naturally-occurring egg parasites Scelionidae or Mymaridae, don't know what else.
Also, any experience with Trece lure for filbertworm?

Hi Jan,
How does one recognize the damage from filbertworm? How did the grower
know it was filbertworm?
Here is a picture of a moth I caught in CM traps in apple last year,
between Selma and Caruthers. The flight lasted from April 14 to May 12.
It
looks similar to these pictures of filbertworms.
(Filbertworm is Cydia (Melissopus) latiferreana, Tortricidae)
Thanks, Devin Carroll

Does anyone know if Advan's new sprayable codling moth virus is organic and if it would work on these filberworms?

Advan's new codling moth product, CYD-X, is OMRI listed.
Rob Fritts is Advan's field development manager and he gave me a label when he and Mitchel King were out looking at a grower "trial" of another product on grapes.
I don't know the efficacy on different Cydia spp, but his mobile number is (559) 269-2741 if you want to chat with him.
Good luck, Laura Breyer

Devin,
In looking at the photo of the moth in your traps in apples last year, the banding on the forewings is in about the right position, but the grey-white base color is not typical for the filbert worm moths I trapped this year. I ran traps in oaks on the Kings river near Sanger and Kingsburg from March through October. I saw a strong first flight in the first two weeks of May (from overwintered larvae), a low but consistent flight through the summer, and a smaller but distinct second flight in early October (from larvae in new crop acorns).
All of the moths I trapped this year were typically colored like the light tan moths in the upper line of the bug-guide attachment you sent. The notable thing about filbert worm moths is that the darker bands on the forewings are quite iridescent, much like the copper patch on codling moth wings. I couldn’t tell from your photo if that was the case with your moths in the CM traps. Also, the pheromone isomers for codling are basically alcohols, while the pheromones for filbert worm are acetates. There could be some cross-attraction, but is unlikely. So if you caught a lot of non-targets in your CM traps, I’m guessing they probably were not filbert worm moths.
