Insects provide numerous primary environmental services from
recycling of nutrients to pollination, beside their
fundamental contribution to food resources of many
vertebrate animals. Consequently insects should be at the
core of any commitment of the world to the International
Convention on Biodiversity. Pollination is one of the most
important mechanisms in the maintenance and conservation of
biodiversity and in general life on earth. Pollination also
benefits society by increasing food security and improving
livelihoods, hence pollinator diversity is important. Two
thirds of the world’s 3000 species of agricultural crops
require agents for pollination. Pollinators provide an
ecosystem service that enables plants to produce fruits and
seeds. Pollinators are found in diverse groups of the
animal kingdom, including birds, bats, reptiles, insects,
etc. Among the several animals, insects particularly honey
bees, dominate in providing pollination services to several
plants. Several other pollinators including carpenter bees,
bumble bees, megachilids, halictids, sphecids, andrenids,
syrphids, etc. are known to occur in the country. We have
always under evaluated their contribution perhaps because of
our limited insight into their behaviour mechanism for
nesting. But today the modern beekeeping suffers from a
magnitude of problems, including parasitic mites, honey bee
diseases, inability of honey bees to work at low temperature
and adverse climatic conditions. These difficulties threaten
the honey bees general utility as an agricultural
pollinator. Therefore, Conservation of biodiversity of honey
bees and wild pollinators is important to realize the
potential yields of several cross-pollinated crops, hybrid
seed production, crops grown under poly-house conditions and
in conservation of rare and endemic species in the country.
Keywords: Bees, biodiversity, pollination,
