Sawfly larvae have been munching the leaves of my gooseberry bush. We only realised what was going on this week (never had it before) and have been picking them off and squashing them as best we can. The back half of the bush is virtually leafless, but is putting out new foliage at the tips of each branch. The fruit have set and are about 5-6mm across. Is there an easier way to get rid of the larvae? Will the bush survive and will the fruit still swell on the leafless branches? How can we stop this happening again?
Thanks for any advice.
