Abstract
Activity and behaviour of the honeybee Apia mellifera L.
depend upon many factors operating simultaneously and react
to some environmental condi tions·in a similar manner YJherever
they occur . It is extremely difficult to measure the
effect of one factor apart from the others.
The ecological factors prevailing in the location of an
Apiary should be studied to know the optimum condition for
honeybee activities.
Weather is the most important factor affecting honeybee
activities. A close relationship between weather factors
and honeybee activities was recorded by many authors. They
considered the temperature to be the moat important factor
nffecting honeybee activities. Temperature, in general,
affects djrectly tne consumption of foods, longevity of
bees, flight and brood rearing. Therefore,it was important
to study the effect of temperature on the activity of the
honeybee colonies under the prevailing local environmental
conditions of Kafr El-Sheikh region. The study included
the effects on brood rearing, flight activity, nectar and pollen
gathering, honeybee production and efficiency of honeybee
colonies to thermoregulate the inside of the brood
nest.
