Honey bees spend a lot of energy on the harvesting and processing of feed. External and
internal factors can reduce or increase the physiological costs of bees, and accordingly affect
the development and productivity of colonies. The fact that getting bee pollen slows the flying
activity of bees. The reason for this is mainly the design features of devices – pollen collectors,
and the specific behavior of bees in the area of the tray.
The purpose was to investigate the ethology of flying bees in the area of the airship and
to improve the pollen collector. This will create the preconditions for improving the
technology of obtaining bee pollen. The object of research was flying bees and the most
prevalent in Ukraine designs of hanging pollen collectors. Three groups of bee colonies were
used in the experiments (n=10): control – maintenance without pollen collectors; experiment
1 – installed on the bee homes pollen collectors with narrow-high gratings; experiment 2 –
used pollen collectors with elongated grate.
In 2018, on the basis of two apiaries, it was recorded a video of the ethology of bees near
the flying space in different periods of the day during two weeks. On the basis of these
researches, the design of the hanging pollen collector was improved. The pollen collector
prototype (10 devices) was printed on a 3D printer, the effectiveness of it was tested on the
same apiaries in 2019. In the process of testing, the performance of devices was determined in
comparison with analogues and was examined the ethology of bees.
According to the results of video registration, zones of intensive movement of bees on
the flying board of bee homes were determined. It has been established that the bees flying
out and flying to their nests move sufficiently in a narrow corridor – the flying zone, and in
small quantities can be displaced 3–8 cm from it and are almost not delayed on the flying
board or the lower part of the hull of pollen collector. Bees spend 20–30 % more time when
pollen collectors are on, because of accumulations them near the central sections of the grids
and complications when passing through their holes.
In the work zone of the pollen collector, it is proposed to use two gratings for removing
bee pollen. They are placed in pollen collectors as a cone, which increases the area of openings
for the passage of bees twice. The delineation of the bees' flows provides by a curtain that is
installed in a corridor located at the opening of the flying place. The bees which are flying out
emanate from the nest through the discharge tubes which located on the sides of the pollen
collector.
For getting bee pollen is slowing down the harvesting work of bees, which reduces
productivity and suppresses the development of colonies. The application of an improved
pollen collector helps to the division of flying bees, increases their flying activity and
productivity in the conditions of getting bee pollen.
