I've never seen honeybees, bumblebees or hoverflies on HT or similar roses. Only on dog rose or rosa rugosa.
I'm pretty sure Kew, like other tropical houses I've visited, use bioligical controls for insect pests. I've not been to Kew but I've visited less famous places and if they can afford to use bio controls, I'm sure Kew can. I grew a banana plant indoors once; it's an aphid magnet. I was so tempted to use a systemic pesticide but in the end put it outside for the natural pest controllers. It died in the greenhouse during a hard winter and I wasn't too sorry!
I used to grow regal pelargoniums and they attracted whitefly like fury
Those things were resistant to all insecticides anyway so you had to sit with a tiny brush and some meths to treat their eggs on the underside of leaves
Whitefly? You just use those yellow sticky card thingies from an organic gardening catalogue. (Though I see Lakeland are now selling something similar). Worked a treat in my greenhouse down in England. We don't seem to get whitefly here; maybe they just can't fly against the wind!
