Maggots in My Cherries Again This Year?
Advice from the Help Desk of the
UC Master Gardener Program of Contra Costa
Help Desk Response: The spotted wing drosophila (Drosophila suzukii) is a relatively new pest of cherries and other soft fleshy fruits (strawberries, raspberries, blackberries, blueberries, etc). Unlike other vinegar flies that attack rotting or fermenting fruit, the spotted wing attacks maturing fruit. The name spotted wing drosophila comes from the single black spot at the tip of each wing of the male adult. Don't think though that you will be able to identify this fly by those markings without magnification because these adults are small, really small. The female is able to penetrate the skin of the fruit to lay her eggs and this act creates a small depression (“sting”) on the fruit surface. The eggs hatch and the maggots develop and feed inside the fruit, causing the flesh of the fruit to turn brown and soft.
An alternative to malathion with fewer negative environmental effects would be spinosad (e.g., Monterey Garden Insect Spray and see http://www.ipm.ucdavis.edu/TOOLS/PNAI/pnaishow.php?id=65); h
Since spotted wing drosophila attacks ripening fruit it is often not noticed in home garden situations until the fruit is being harvested. Sprays at this time will not protect the crop because maggots are already in the fruit. If only some of the fruit are infested, you can salvage some of the crop by harvesting immediately and sorting the fruit, removing any with “stings” on the surface. It is recommended that all infested fruit be removed from the tree and picked up from the ground. It should then be placed in a sealed plastic bag and disposed of in the trash or buried. Do not put the infested fruit in your compost pile as it may not get hot enough to destroy the eggs and larvae still in the fruit.

It's Time to Prune Apricot & Cherry Trees

Warmer winter is hurting California cherry crop
The drought isn't helping matters, but the primary concern for cherry farmers in California is the lack of winter chill, reported Lisa Morehouse on KQED's The California Report.
Morehouse spoke to Bill Coates, a UC Agriculture and Natural Resources expert based at the UC Cooperative Extension office in San Benito County. He said cherries are more sensitive than other crops to a lack of chill hours. Because of a warming weather trend during the winter, bing cherry trees look confused about what season it is.
“You have some ripe cherries, you have some blossoms, some branches that are almost devoid of leaves, and you have some buds that are still dormant,” he explains. “And this is all a result of lack of chilling.”
Bing cherries need about 1,000 hours under 45 degrees for healthy dormancy. Last year San Benito County got just over 500 hours.
"People may disagree on the cause of the change," Coates says, "but there definitely has been a change in the climate, and it's going to impact tree crops greatly."
