Whitefly infestations

Morning everyone
I hope you have some sunshine where ever you are today.
Whitefly....never usually a problem on the veg crops until this year 
Sprouts ( ive had cabbage white infestations) cauliflowers and the seed heads on some sutherland kale ive left for the bees. It looks like a dense grey mould there are so many of them

The sprouts and cauliflowers are covered not that this has stopped the aphids. Any suggestions for non chemical management other than leaf removal??

I actually haven't seen hardly any cabbage white butterflies so far this year. Anyone else noticed this?

Thanks in advance

Saw my first cabbage whites yesterday - one of which had somehow got under the butterfly netting although fortunately I got it out quite easily.
