One of the most familiar insects in the world is the Honeybee. This member of the insect order Hymenoptera plays a key role in the human and natural world. More has been written about honeybees than any other species of insect. The human fascination with this insect began thousands of years ago when people discovered what wonderfully tasty stuff honey is! Honey is a thick liquid produced by certain types of bees from the nectar of flowers. While many species of insects consume nectar, honeybees refine and concentrate nectar to make honey. Indeed, they make lots of honey so they will have plenty of food for times when flower nectar is unavailable, such as winter. Unlike most insects, honeybees remain active through the winter, consuming and metabolizing honey in order to keep from freezing to death. Early humans probably watched bears and other mammals raid bee hives for honey and then tried it themselves. Once people found out what honey was, next they had to learn how to get it from the bees safely! Honeybees have a bright color pattern to warn potential predators (or honey thieves!) that they have a weapon to defend themselves. Their weapon is a modified ovipositor (egg-laying tube). This is combined with a venom gland to create a stinger (formally known as an aculeus) located at the end of the abdomen. Because the stinger is modified from a structure found only in females, male bees cannot sting. When the hive is threatened, honeybees will swarm out and attack with their stingers to drive the enemy away. Honeybees, like most insects, look at the world through compound eyes. These are made of hundreds of small simple eyes called ommatidia. The images received by all the ommatidia are put together in the insect's brain to give it a very different way of seeing the world. To see the world the way a bee does, check out Andrew Giger's B-Eye web site in the links section. Honeybees are social insects. In the wild, they create elaborate nests called hives containing up to 20,000 individuals during the summer months. (Domestic hives may have over 80,000 bees.) They work together in a highly structured social order. Each bee belongs to one of three specialized groups called castes. The different castes are: queens, drones and workers.

Flower nectar is one of two food sources used by honeybees. The other is pollen. Both are gathered by the field bees as they fly about on their daily foraging flights.
Honeybees are important pollinators
There are four different species of honeybee in the world:
Cave paintings in Europe indicate that early peoples were harvesting honey 8,000 years ago. The next step in human/honeybee relations came when people started keeping bees in man-made structures rather than just going out and searching for wild hives. The ancient Egyptians were beekeepers and their methods were copied throughout the Mediterranean and Middle East. They used the Western Honeybee, and that is the most widely used species today. The Eastern Honeybee was also domesticated long ago in China. The other two species of honeybee do not nest in cavities and so were not suited to being put into hives. The subject of beekeeping is beyond the scope of this web page. For more information, see the links below.

What are "Killer" Bees? More properly called Africanized Honeybees, these come from a subspecies of honeybee (Apis mellifera scutellata) released accidentally in Brazil in 1957. They were imported from South Africa by a researcher who was attempting to produce a variety of honeybee better adapted to the tropics than the European Honeybee. Unfortunately, Africanized Honeybees not only produce honey better in hot climates, but they are also much more aggressive at defending the nest. Many people have been killed by mass stinging resulting from getting too close to a nest of Africanized honeybees. The escaped bees did well in the wild and began reproducing and expanding their range across South America into Central America and Mexico. They were recorded in Texas in October 1990, California in November 1994 and Oklahoma in 2004. Since they are adapted for tropical conditions, they may not expand their range beyond the southern part of the U.S., but that remains to be seen. They can tolerate up to 3 1/2 months of freezing weather. |

WHAT IS COLONY COLLAPSE DISORDER? Colony collapse disorder (or CCD for short) refers to a mysterious malady affecting domestic honeybees that causes them to leave the hive and not return, leading ultimately to death of the colony. First noticed in late 2006 in North America, CCD has been the focus of much research to try to determine what is causing it. Pathogens, parasites, environmental toxins and even cell phone transmissions have been the subject of investigation. As of this writing (November 2007) the one factor that has been identified as being uniquely associated with CCD is a virus known as Israeli Acute Paralysis Virus (IAPV). It is not proven yet that IAPV is the sole cause of CCD, but it is found in nearly all hives affected by CCD. A possible scenario is that CCD is triggered by various stress factors in bees infected with IAPV. Research is currently underway to test this hypothesis. For more information on CCD, see the Mid-Atlantic Apiculture Research and Extension
Consortium website.
