Spotted Wing Drosophila: A New Threat To Tender Fruit And Berry Crops. Completely destroys bush berries. Nobody wants maggots in fruit.

To determine if present put your picked berries in salty water and leave for an hour or so. The maggots should float if present. The pest is in NY state and in the Niagara region now.
The SWD will attack thin-skinned fruit such as raspberry, blackberry, blueberry, strawberry, apricot, cherry, plum, peach, nectarine, hardy kiwi, elderberry, currant, dogwood, mulberry and sometimes grape.

If you stir or swirl the water around a bit they sink very slowly and you can see them being carried by the current, but they do eventually sink to the bottom. The maggots do not float as mentioned in previous post.

The adults are easy to spot. The maggots are a bit more difficult. ... es2013.htm Latest update. Pictures

Have just read this today. Quite frightening. I must be on the lookout for this pest. I do have a lot of fruit flies around in summer but didn't ever take notice of their appearance as they are so tiny so wouldn't have known if they were spotted Wing Dosophila. They are certainly a real nuisance once they are around in the house or the composter. Someone or something always wants to take advantage of our hard work. Surely don't want to lose my strawberries or raspberries to these fruit flies.
