Last year I had loads of cherries on my 3 year old tree, for the first time. But 90% of them contained maggots! (My friend over the other side of town had them in her cherries too).
I’ve done lots of research and found that there is a new pest called the Asian cherry vinegar fly (drosophilia suzukii), which arrived here in 2012 and is spreading (currently only in the south of England I think). The bad news is they don’t just lay eggs in ripening cherries, but also strawberries and all types of currant.
Traps and liquid attractant seem to be very expensive – e.g. from Agralan 2 traps and 5 litres of liquid plus postage is £50. Other options seem to be for commercial growers only, e.g. £250 minimum order from Trece.
Have you heard of this, do you have any better options, please?
