For the past few years, my currants, in particular the red and the black variety (the latter is actually a cross with a different berry), have been damaged by some insect(s). It’s the same type of damage year after year. Almost all of the red currants have some kind of damage by the end of the season and are rendered inedible. A lot of the damaged fruit simply falls to the ground. This damage coincides with the presence of brown marmorated stink bug (although this year, so far, I have only seen one specimen, which I crushed), two other types of stink bug, and a fly (?) with orange striped wings. Every season I collect the bugs that I can see and catch in a jar with a soap solution. A picture of my “catch” from earlier this season is attached. So far this season, I have collected over a hundred of these bugs (stink bugs are fairly easy to collect but the fly is super elusive; it is featured in the uploaded picture though). Occasionally, I also find small eggs laid on the underside of the leaves of a nearby honey berry bush. I believe they are laid by the stink bugs. Pictures of clusters of two types of such eggs are also attached, one shows small bugs emerging from a cluster of eggs. Please help me identify the bugs and the fly and let me know which one(s) cause the damage and how to manage this problem. I'd be happy to attach a picture of the fruit damage but it appears that only 3 files can be uploaded. Thank you very much for your help!
