bring about fertilization of the ovules in the flower by the male gametes

some non-bat mammals (monkeys, lemurs, possums, rodents) and some lizards
pollinate certain plants. Among the pollinating birds are hummingbirds,
honeyeaters and sunbirds with long beaks; they pollinate a number of
deep-throated flowers. Cycads, which are not flowering plants, are also
pollinated by insects. A pollinator is different from a pollenizer, a

is a fine to coarse powdery substance
comprising pollen grains which are male microgametophytes of seed plants,
which produce male gametes (sperm cells). Pollen grains have a hard coat
made of sporopollenin that protects the gametophytes during the process of
their movement from the stamens to the pistil of flowering plants or from
the male cone to the female cone of coniferous plants. If pollen lands on
a compatible pistil or female cone, it germinates, producing a pollen tube
that transfers the sperm to the ovule containing the female gametophyte.
Individual pollen grains are small enough to require magnification to see
detail. The study of pollen is called palynology and is highly useful in
paleoecology, paleontology, archaeology, and forensics. Pollen in plants
is used for transferring haploid male genetic material from the anther of
a single flower to the stigma of another in cross-pollination. In a case
of self-pollination, this process takes place from the anther of a flower
to the stigma of the same flower.
is the process by which pollen is transferred to the female reproductive
organs of a plant, thereby enabling fertilization to take place. Like all
living organisms, seed plants have a single major goal: to pass their
genetic information on to the next generation. The reproductive unit is
the seed, and pollination is an essential step in the production of

is a technique used when natural, or open
pollination is insufficient or undesirable. The most common techniques are
for crops such as cucurbits, which may exhibit poor pollination by fruit
abortion, fruit deformity or poor maturation. Hand-pollination is an
option only on a small scale, but is a common technique by home and small
market gardeners, involving the transfer of pollen with an artist's brush
or cotton swab from male to female flowers. Sometimes the corolla is
removed from male flowers and the flower itself is brushed against the
stigmas of female flowers. The principal reasons for hand pollination
include a paucity of natural pollinators, avoiding cross-pollination

production of hybrids.Mini drones

Imidacloprid is the most widely used insecticide in the world. Compared to
organophosphate and carbamate insecticides, neonicotinoids cause less
toxicity in birds and mammals than insects. Some breakdown products are
also toxic to insects. Neonicotinoid use was linked in a range of studies
to adverse ecological effects, including honey-bee colony collapse

is a sugar-rich
liquid produced by plants in glands called nectaries, either within the
flowers with which it attracts pollinating animals, or by extrafloral
nectaries, which provide a nutrient source to animal mutualists, which in
turn provide antiherbivore protection. Common nectar-consuming pollinators
include mosquitoes, hoverflies, wasps, bees, butterflies and moths,
hummingbirds, and bats. Nectar plays an important role in the foraging
economics and overall evolution of nectar-eating species; for example,
nectar and its properties are responsible for the differential evolution
of the African honey bee, A. m. scutellata and the western honey bee.
Nectar is an ecologically important item, the sugar source for honey. It
is also useful in agriculture and horticulture because the adult stages of
some predatory insects feed on nectar. For example, the social wasp
species Apoica flavissima relies on nectar as a primary food source. In
turn, these wasps then hunt agricultural pest insects as food for their
young. For example, thread-waisted wasps (genus Ammophila) are known for
hunting caterpillars that are destructive to crops. Caterpillars however,
do eventually become butterflies and moths, which are very important
pollinators. Nectar secretion increases as the flower is visited by
pollinators. After pollination, the nectar is frequently reabsorbed into

is a sugary food
substance produced and stored by certain social hymenopteran insects. It
is produced from the sugary secretions of plants or insects, such as
floral nectar or aphid honeydew, through regurgitation, enzymatic
activity, and water evaporation. The variety of honey produced by honey
bees (the genus Apis) is the most well-known, due to its worldwide
commercial production and human consumption. Honey gets its sweetness from
the monosaccharides fructose and glucose, and has about the same relative
sweetness as granulated sugar. It has attractive chemical properties for
baking and a distinctive flavor that leads some people to prefer it to
sugar and other sweeteners. Most microorganisms do not grow in honey, so
sealed honey does not spoil, even after thousands of years. However, honey
sometimes contains dormant endospores of the bacterium Clostridium
botulinum, which can be dangerous to babies, as it may result in botulism.
People who have a weakened immune system should not eat honey because of
the risk of bacterial or fungal infection. Although some evidence
indicates honey may be effective in treating diseases and other medical
conditions, such as wounds and burns, the overall evidence for its use in
therapy is not conclusive. Providing 64 calories in a typical serving of
one tablespoon (15 ml) equivalent to 1272 kj per 100 g, honey has no
significant nutritional value. Honey is generally safe, but may have
various, potential adverse effects or interactions with excessive
consumption, existing disease conditions, or drugs. Honey use and
production have a long and varied history as an ancient activity, depicted
in Valencia, Spain by a cave painting of humans foraging for honey at
least 8,000 years ago.
bee member of the genus Apis, primarily distinguished by the production
and storage of honey and the construction of perennial, colonial nests
from wax. Currently, only seven species of honey bee are recognized, with
a total of 44 subspecies, though historically, from six to eleven species
have been recognized. The best known honey bee is the Western honey bee
which has been domesticated for honey production and crop pollination.
Honey bees represent only a small fraction of the roughly 20,000 known
species of bees. Some other types of related bees produce and store honey,
including the stingless honey bees, but only members of the genus Apis are
true honey bees. The study of bees including honey bees is known as

is a natural wax produced by honey bees of the genus Apis. The wax is
formed into "scales" by eight wax-producing glands in the abdominal
segments of worker bees, who discard it in or at the hive. The hive
workers collect and use it to form cells for honey-storage and larval and
pupal protection within the beehive. Chemically, beeswax consists mainly
of esters of fatty acids and various long-chain alcohols.

is a resinous mixture that honey bees produce by
mixing saliva and beeswax with exudate gathered from tree buds, sap flows,
or other botanical sources. It is used as a sealant for unwanted open
spaces in the hive. Propolis is used for small gaps (approximately 6
millimeters (0.24 in) or less), while larger spaces are usually filled
with beeswax. Its color varies depending on its botanical source, the most
common being dark brown. Propolis is sticky at and above room temperature,
20 °C (68 °F). At lower temperatures, it becomes hard and very brittle.

is a type of honey which has a distinctive flavor or
other attribute due to its being predominantly from the nectar of one
plant species. It is stored and labeled separately so as to command a
premium price. While there may never be an absolute monofloral type, some
honeys are relatively pure due to the prodigious nectar production of a
particular species, such as citrus (Orange blossom honey), or there may be
little else in bloom at the time. Beekeepers learn the predominant nectar
sources of their region, and often plan harvests to keep especially fine
ones separate. For example, in the southern Appalachians, sourwood honey,
from a small tree that blooms late in the season, is highly regarded.
Beekeepers try to remove the previously produced dark and strong flavored
tulip poplar honey, just before the sourwood bloom, so it doesn't mix with
the lighter sourwood. During sourwood bloom, there is little else for the
bees to forage.

honey someday again, but there's so many other things in life to enjoy, so
I would rather enjoy all the other things and not worry about the things
that I don't have anymore. And if honey did come back, I would definitely
not mind having another taste of sweet sweet honey. But only as long as I
