Yes, I also have the same problem... I get the usual aphids, green and black fly and also little white wingless ones that I think may be scale insects (Hemiptera). They are kind of crunchy when you squish or scrape them off leaves.
I have been using weak spray solutions of an organic insecticide called SBPI, or SB Plant Invigorator, which works well as both a decent foliar feed and organic insecticide/miticide, but doesn't look like it will completely solve the problem.
Plus I am only spraying my wintering plants indoors, I don't like spraying anything in the garden so come summer it'll be bug central again... they don't seem to have much of an effect on fruit production though as long as I stay on top of them and keep up the manual squishing!
