Whitefly plague

This recent spate of very hot weather has led to a huge population
explosion of whitefly in the trees around where I live in North
Yorkshire. I have had problems with them inside a glasshouse but I have
never seen them occur like this outdoors and so very early in the
season.
Beech seems to be particularly badly affected and many trees are now
well coated in whitefly, dripping honeydew and literally humming. So far
no signs of decent numbers of predators like ladybirds or lacewings.
Anyone else seeing abnormal pest infestations?

Yup! The beeches in the Chilterns are COVERED in whitefly - trimming my
hedge is extremely unpleasant and all trees seem to be dropping honeydew,
not just the usual suspects of lime and birch. I also have lots of aphids
on my roses for the first time ever and although I don't use pesticides,
nary a ladybird adult or larva is in evidence. Damselflies seem to be
taking aphids, but they'll be too fat to fly before long.
