Have I beaten the sawfly?

I haven't eaten a Gooseberry for a couple of years because of Sawfly attacks.

Last year I watched the bushes early on and caught them whilst they were still low on the bushes.

Living on an island I can't just pop round the garden centre etc, so I went to my store cupboard and found a year or two old bottle of "Crop saver" and sprayed the caterpillars with this. They obviously didn't like it and died. But even though I saved 80% of the foilage, I didn't get a single berry.

This year the bushes are looking good, the bees are working the flowers and not a single sawfly has yet been seen, does this mean I killed off the next generation of sawfly?

Yours the ever vigilant sawfly killer.

Don't know the specific answer to your question, but I believe that Crop Saver contains malathion as its active ingredient?  If so, just to point out that it became illegal to use any malathion based product at the end of last year (so your spraying last year was fine, but not this year).
