A bumper crop of sour cherries turned to mush thanks to Spotted-wing Drosophila. Instead of having jam and pie, we have rotting fruit lying on the ground. Very peeved. #gardening #pests #SpottedWingDrosophila #SourCherry
@friesen5000 Ugh I'm so sorry. My experience pretty much every year with both my apples and peaches...fruit ends up rotting as it starts to ripen 🤬

@friesen5000

us too
gutted :(

@bearsong It sucks! While not exhaustive, so far my search for treatment has only turned up chemical pesticides. Apparently it's the year for them, at least around here.

Invasive fruit flies cause problems for Manitoba farmers | CBC News

An invasive fruit fly called the spotted wing drosophila is festering in Manitoba crops.

@friesen5000 I’m not sure of the quantity you’re dealing with, but my adaptation to a drosophila nightmare in my local blackberry patch was to soak all the berries in vodka for a month, then toss out the berries and drink tasty cocktails. Probably not feasible on a commercial farm scale.
@ncgleason brilliant! I just have 2 trees so would be feasible.
@ncgleason also, did you notice a drop in population levels the following year since so many larvae were 'pickled'?
@friesen5000 I can’t provide a scientific answer to that because I went a couple weeks earlier in the season in the following year, so there were fewer fly larvae, but could have been either timing or overall population level. I also only harvested maybe 10% of what was available because it’s a shared neighborhood resource and I don’t know how many of us pick from there. Also hard to say whether my extraction levels could have affected insect habitat to a measurable extent.
