FLOWER CHOICES OF BEES
• Bees choose flowers by color and scent. They
are attracted to flowers by scents that are
attractive to them. Flowers have patterns
(nectar guides) that show bees where to look
for nectar. Bees see blue-green, blue, violet,
and ultraviolet. UV patterns create a “landing
zone” attracting the bees to the nectary.
When the nectar diminishes so does the
attraction, and the bees move on to other
flowers.

Pollen
Young bees must consume large
quantities of pollen in the first two
weeks of their adult life.
The consumption could last up to five
days of age.

POLLEN
Pollen is a fine to coarse powder containing the
microgametophytes of seed plants, which produce the
male gametes (sperm cells). Pollen grains have a hard
coat that protects the sperm cells during the process
of their movement between the stamens to the pistil of
flowering plants or from the male cone to the female
cone of coniferous plants. When pollen lands on a
compatible pistil of flowering plants, it germinates and
produces a pollen tube that transfers the sperm to the
ovule of a receptive ovary. The individual pollen grains
are small enough to require magnification to see detail.

Nursing duties are normally finished and
field duties are undertaken when bees
are 10-14 days old.
At the time the requirement for pollen
decreases and the chief dietary need
becomes carbohydrates.
Carbohydrates are obtained from nectar
and honey.
24
Nectar
• Nectar is the sugar rich liquid produced by the
flowers of plants in order to attract pollinating
insects.
• It is also the principal raw ingredient of honey.
25
Although its main ingredient is natural sugar (i.e., sucrose (table
sugar), glucose, and fructose),[4] nectar is a brew of many
chemicals. For example, the Nicotiana attenuata, a tobacco plant
native to the US state of Utah, uses several volatile aromas to
attract pollinating birds and moths. The strongest such aroma is
benzyl acetone, but the plant also adds bitter nicotine, which is
less aromatic and therefore may not be detected by the bird until
after taking a drink. Researchers speculate the purpose of this
addition is to drive the bird away after only a sip, motivating it to
visit other plants to fill its hunger, and therefore maximizing the
pollination efficiency gained by the plant for a minimum nectar
output.
26
Nectary Gland of a Flower
• The nectary is the gland that secretes nectar.
It is usually located at the base of the f lower.
This forces pollinators to brush against the
flower’s reproductive structures to reach it.
WATER
• Honey bees will consume water daily
• It is best if the beekeeper supplies the
water and not the neighbors swimming
pool or horse trough.
