Bees as pollinators
Bees are essential to our daily lives. If you eat fruits, vegetables, or nuts during the day, there's a good chance your food has been helped along by a bee. By pollinating over 120 crop plants, it is estimated that bees pollinate approximately one-third of the world's food crops. Besides producing honey, the honeybee (Apis mellifera), has been used extensively for commercial pollination. The value of pollination service by bees is worth billions of dollars annually. Bees also pollinate our native plants that provide food and habitats for other species.
Pollination is the process by which pollen is transferred in the reproduction of plants. Pollination by insects, or entomophily, is one form of pollination, which means that the pollinator actually moves the pollen grains from the anther of the flower to the receptive part of the carpel or pistil. Bees are attracted to plants that have brightly colored petals and are strongly scented.
Colony Collapse Disorder
In the past decade, there has been an unrelenting decline of worker honeybees worldwide. In 2006, this phenomenon became known as Colony Collapse Disorder. There are multiple factors playing a role in honeybee colony declines, including parasites and disease, genetics, poor nutrition, and pesticide exposure.
Conservation and Beekeeping
One of the earliest bee fossils found to date is from the early Cretaceous Period, approximately 100 million years ago. Since bees are so important to global agriculture, our lives, and to the planet, it's important to take measures to keep bees healthy. Planting native plants that attract bees and other pollinators to our gardens is a very simple solution for local conservation, and of course if you must use them, choose pesticides that are certified organic. Beekeeping is not only a popular way to harvest honey, it's a good way to keep bees in check, healthy and fed.
