Planted two gooseberry bushs last year, this year they started out great but now all (yes ALL!!!!) the leaves have fallen off, the four blue berry bushs with them are fine. The only thing that I have changed is that i've used tree bark to weed supress around the six bushs, anyone got any ideas.

Sounds like our old friend, sawfly.

fallen or disappeared? are the leaves on the ground? what do you water with?

[Jim the builder]

Actually I would say disappeared, I water them from a butt

Sawfly.

I'll echo that................ sawfly

Yep! Sawfly. i had them too but i very carefully sprayed my bushes
after days of picking n squishing had zero effect.
They seem to be ok now.

Yep, I said that in the first reply!

My raspberry plants with sawfly out the back garden didnt have no leaves it was just left with skeleton leaves ( the veins)  i think we must have them in all the soil out the back as i have holes developing in the blackcurrant leaves too.  i tried looking and found more tiny spiders than anyting else, they had sort of curled the leaf around with a web that only showed once uncurled, greeny type colour. Any ideas

I'd be interested to find out too BQ.  I have a couple of raspberries where the leaves have been munched, just leaving behind a lacy remnant....

That lacy bit is absolutely sawfly as that is what it did to my lovely yellow raspberries we were growing for florence 
I dug up and burnt as no soil now crosses from here to the plot just incase
