Charles:

I live where insects were invented, from whence they subsequently spread to the rest of the world, but I have virtually no insect problems on sour cherries, and I have grown Northstar, and am currently growing Meteor and Montmorency. Together with Asian pears, it is one of the fruits I really don't have to spray at all.

The single insect that can trouble my sour cherries is the cherry fruit fly, which shows up as a small, white larvae, usually found when pitting the fruit. This is a single-generation insect with quite a simple lifestyle. It hatches out in damaged cherries left on the tree, drops to the ground with the cherries, and burrows into the soil beneath the trees to pupate. I nearly always hoe around under the cherry trees once or twice in spring, perhaps not all the way out to the drip line but at least until I get tired. A small motorized tiller would do an even better job. This disturbs the pupae, exposes them to drying, and greatly reduces the hatch. They do not burrow very deeply, and if you can hoe 2-3 inches you get them. In recent years, I have been able to nearly eliminate these larvae from the cherries. The other factor of course is to clean the tree of cherries to the extent possible at picking time, and discard those that are bird damaged far from the tree.

Do you have other insects bothering your cherries? If so, they are not playing fair. There should be no need to have to settle for small cherries. I just planted a Balaton and a Danube this spring, and expect to deal with the cherry fly the same way on these new cultivars.
