Aphids and whitefly on greenhouse peppers

| Does anyone on this NG have an effective control of whitefly and aphids
on sweet peppers. My plants are crawling with the wrtetched things, and
it seems that a lot of the aphids/whitefly are tolerant of a lot of the
control sprays and chemical treatments.

Whitefly - you can reduce a great deal by vacuum cleaning - use the
small brush that you'd use for delicate things so you don't damage the
leaves. Biological control - Encarsia - widely available.

I use Bio Spray Day, I've had 100% success with this on white and
black fly.

Bit late now perhaps but you can buy a pack of 7 double sided flypapers
specially made to attract whitefly, greenfly, blackfly (there's a bluebottle
on mine, so no colour prejudice!!) thrips and midges. (Bio make them) I
bought a pack last year and still have two for next year.
A very good thing for getting rid of aphids is softsoap (Not washing-up
liquid nor hard soap from the bathroom!) - Chempack(?) from the garden
centre - but only use sparingly on the massed aphids because it affects
leaves adversly if used often. Perhaps a spray with clean water a few hours
later might be effective - must try that myself if my greenhouse plants are
attacked. The theory is that soft soap de-greases the aphids and they die
of dehydration!
Best of luck
