Worms in my Raspberries

Asked September 4, 2014, 12:08 PM EDT

I am finding 1/4" white tiny worms in many of my raspberries. I have started picking them as they start to ripen in hopes that the worms will not be a problem when they are ripe. I don't know how they have been infested. Do you know what what is causing this? Is it due to our weather this season? If it's cultural, is there anything I can do to prevent this another season. I have been throwing overripe berries with worms on the ground. Is this ok or is this a bad practice. I have Fall Gold growing next to my red berries and it doesn't seem that the worms are a problem with them. Will freezing the berries kill the worms and make them edible? If I eat fresh berries and happen to get a worm, can they cause problems?

Thank you for your question about your raspberries.

This sounds like spotted wing drosophila, which is a new pest to South Dakota.
