I've been growing sweet and sour cherries for over 30 years in Burnaby, BC, and have never had a problem with maggots in the cherries until this year. The sour cherries had a few maggots, especially if they were over-ripe; but I don't recall ever seeing maggots in the sweet cherries. Now that the Stella cherries are ripening, I noticed that some of them felt soft inside; so I investigated. They were soft because the fruit around the seed had been eaten away by some tiny, white maggots, only a couple of millimeters long and quite thin. I also noticed that the infested fruit had very small holes in the skin. The holes only became noticeable by squeezing the fruit lightly, causing some juice to appear at the surface. From what I've read on the Web, these appear to be the maggots of cherry fruit flies. Has anyone else noticed a recent increase in these pests, or is this a local phenomenon? It seems that most of my cherry crop is infested with them.
