Summary: | The study was conducted on bee families of Apis mellifera carpatica and Apis
mellifera ligustica breeds. The bees were housed in multi-storey hives. The
experimental period was of 6 months. The resistance to wintering was evaluated on
the basis of several apicultural indicators: mortality, feed intake during the winter,
general state of the family. Mortality was 35% during wintering for the Carpathian
bee and 52% for the Italian bee. The differences were very significant (p≤0.001).
When wintering finished all bee families were in good strength. The general state of
the bee family was as follows: the Carpathian bee had a strong family when
wintering started and ended with a median power; it had a large number of young
bees and sufficient reserves; no diarrhoea or mould were noticed; relative humidity
was 74%. The Italian bee had a strong family when wintering started and ended
with half of the power because of the high mortality during the winter; no diarrhoea
or mould were noticed; relative humidity was 69%. |
