Art,
Once the fruit is infested, cold storage for 3 days at 33F will kill the majority of larva in the fruit, retaining the integrity of fruit at the time of harvest from further injury. * If the fruit are clean (uninfested) at the time of application AND the material has a high degree of efficacy in reducing SWD egg laying, the fruit will remain clean. * If the fruit has been newly infested with one or more eggs you may get some efficacy from the application to reduce larval activity, with protection from further infestation in the field depending on insecticide efficacy. Its likely they will remain infested with larval activity increasing in storage unless cold treated. * Sound stone fruit are much less likely to be infested. We have only reared a singly fly from sound peach. We have seen oviposition on plum with no fly emergence. Blueberry have shown to be much less attractive to SWD then raspberry and blackberry. A 7 day schedule for blueberry using the best materials has been shown to be effective at managing the pest on many farms with consistent pest management programming. In the Hudson Valley a 3d program is required in raspberry and blackberry for commercial quality fruit. Best, Peter J.

I'm thinking of peaches or plums and blueberries. -- Art Kelly Kelly Orchards Acton, ME
