Are there any less aggressive systemic insecticides available? I certainly
don't want to massacre the local wildlife. I have 2 problems ... lots of
whitefly on my fuchsias (mostly in a conservatory) ... and an unknown pest
on my Phygelius.

Whitefly and other aphids can usually be cleared with a foliar
application of nettle infusion. At this time of the year you could take
your fuchsias outside for a few days and that often works on indoor
plant pests.

There's an urg FAQ about nettle infusion at:
