“You will probably more than once
have seen her fluttering about bushes, in a deserted corner of your garden,
without realizing that were carelessly watching the venerable ancestor to whom
we probably owe most of our flowers and fruits (for it is estimated that more
than a hundred thousand varieties of plants would disappear if the bees did not
visit them), and possibly even our civilization, for in those mysteries all
things intertwine” – Mavrice Maeterlinch, The Life of the Bee
(published 1902)
There are about 20,000 species of
bee. Solitary, bumble, stingless and honeybees are examples. All bees play an important
role in agriculture -crop and natural plant pollination.
The honeybee is a very fascinating specie. It demonstrates social
traits, distinct divisions of labour, store honey, have a reproducing queen and
build large colonies. Honeybee has since become vital necessity for humans as
it contains products which are of immense benefits, such as honey, venom,
propolis and wax. Honey has been identified to be a very potent cure for a
number of diseases, the venom of the honey sting is employed in the treatment
of arthritis and other autoimmune diseases. Research has also shown that humans
rely on honey for one-third of their crops, including the majority of fruits
and vegetables.
It is however unfortunate that
the population of this invaluable insect have started to significantly decline
in the last ten years. This phenomenon is known as Colony Collapse Disorder
(CCD).
This unfortunate development
which has shown serious decline in North America and Europe more than any other
part of the world should be seen as serious threat to food supply. In the
United States, statistics shows that 42% of colonies of beekeepers died between
April 2014 & 2015.
Scientist and beekeepers are yet
to determine categorically the causes of this phenomenon, however some factors
have been suspected to be responsible for the decline in honeybee populations.
The Varoa mite which has been described as an enemy of the honey bee is
one of the suspected contributing factors. This mite is “extremely damaging to
the honey bee colonies. They mainly kill by acting as disease carriers and
transmitting any number of viruses and bacteria to the bee. It cripples adult
and kills potential workers at the larval stage and this kills the honey bee
colony. In temperate climates, Varoa
mite infestation typically kills an entire colony within 3 to 4 years, while in
warmer areas death can occur within just 6 months”. Chemicals and acidic
substances like Acarcides and Formic acid are often used by beekeepers to treat
their hives in order to fight this enemy -Varoa
mite
The use of Chemical Pesticides by
farmers to spray their plants in order to protect them from harmful insects and
diseases is another contributing factor. These pesticides affect honey bees
that rummage through the flowers of these treated plants. This often leads to
the death of the honey bees especially when high doses are used. Even when low
doses are used “at even sub-nanogram levels, it impairs directly or indirectly
their ability to navigate back to their hives. This demonstrates that honey
bees are exquisitely delicate creatures and are influenced by particulate
toxicity in the range of parts per billion”.
Climate change, honey bee
importations facilitated by globalisation and over exploitation of the honey
bee are factors that also contribute to this phenomenon. If a honey bee keeper
in France sold his honey bees to a man in Syria, the honey bees will have to
face the challenge of adapting to their new environment, especially when the
environments involved are extremely different in climate conditions, then their
chances of survival will be very low. Similarly, unstable weather conditions
may also lead to the death of the honey bees. It was reported that Canada loses
23.8% of her honey bee population between 2009 & 2010 due to unusually cold
and long winters.
All hands must therefore be on
deck this menace; otherwise there will be consequences, especially in food
supply. Achin Steiner, director, United Nations Environmental Program pointed
out in March 2011 that “…..the way humanity manages its nature-based assets,
including pollinators, will in part define our collective future in the 21st
Century. The fact is that of the 100 crop species that provide 100% of the
world’s food, 70% are pollinated by bees”.
