There's undoubtedly a degree of hybridisation there, but we still have bees
which are morphologically identical to specimens collected before 1850 (I
believe the first recorded importation of Italians was in 1859), and extremely
similar to remains found in archaeological dig in York (dating to about 1000
AD) and Oslo (about 1200 AD) (Ruttner, Milner & Dews, The Dark European
Honeybee, BIBBA, 1990). I think it's reasonable to conclude that some strains of
the native bee survived. Additionally, Beowulf Cooper reports that many
beekeepers with native strains did not lose their bees to Isle of Wight Disease.
What seems to have happened is that the disease was most serious in the
South-East, where the local stocks were very hybridised, as it's probably the most
suitable part of the UK for Italians. Work done there was then extrapolated,
wrongly, to the rest of the country, with the result that nobody actually
looked at what had happened in those parts of the country where native stocks were
strongest until many years later.
