Queen bee in the context of Burr comb

The western honey bee or European honey bee (Apis mellifera) is the most common of the 7–12 species of honey bees worldwide. The genus name Apis is Latin for 'bee', and mellifera is the Latin for 'honey-bearing' or 'honey-carrying', referring to the species' production of honey.

Like all honey bee species, the western honey bee is eusocial, creating colonies with a single fertile female (or "queen"), many normally non-reproductive females or "workers", and a small proportion of fertile males or "drones". Individual colonies can house tens of thousands of bees. Colony activities are organized by complex communication between individuals, through both pheromones and the waggle dance.

Beekeeping (or apiculture, from Latin: apis + culture) is the maintenance of bee colonies, commonly in artificial beehives. Honey bees in the genus Apis are the most commonly kept species but other honey producing bees such as Melipona stingless bees are also kept. Beekeepers (or apiarists) keep bees to collect honey and other products of the hive: beeswax, propolis, bee pollen, and royal jelly. Other sources of beekeeping income include pollination of crops, raising queens, and production of package bees for sale. Bee hives are kept in an apiary or "bee yard".

The earliest evidence of humans collecting honey are from Spanish caves paintings dated 6,000 BCE, however it is not until 3,100 BCE that there is evidence from Egypt of beekeeping being practiced.

A worker bee is any female bee that lacks the reproductive capacity of the colony's queen bee and carries out the majority of tasks needed for the functioning of the hive. While worker bees are present in all eusocial bee species, the term is rarely used (outside of scientific literature) for bees other than honey bees, particularly the European honey bee (Apis mellifera). Worker bees of this variety are responsible for approximately 80% of the world's crop pollination services.

Worker bees are the caste of bee that perform most of the fundamental tasks of the hive, and they are by far the most numerous type of bee. They are much smaller than drones or queen bees, with bodies specialized for nectar and pollen collection. They perform different tasks around the hive progressively over their lifespans in a predictable order based on their age.

A drone is a male honey bee. Unlike the female worker bee, a drone has no stinger. It does not gather nectar or pollen and cannot feed without assistance from worker bees. Its only role is to mate with a maiden queen in nuptial flight, and often dies after doing so.

Royal jelly is a honey bee secretion that is used in the nutrition of larvae and adult queens. It is secreted from the glands in the hypopharynx of nurse bees, and fed to all larvae in the colony, regardless of sex or caste.

During the process of creating new queens, the workers construct special queen cells. The larvae in these cells are fed with copious amounts of royal jelly. This type of feeding in part triggers the development of queen morphology, including the fully developed ovaries needed to lay eggs. Note however that some newer research shows it is not solely the presence of royal jelly that develops the queen but rather the absence of certain other nutrients fed to worker bees.

The brood comb is the beeswax structure of cells where the queen bee lays eggs. It is the part of the beehive where a new brood is raised by the colony. During the summer season, a typical queen may lay 1500-2000 eggs per day, which results in 1500-2000 bees hatching after the three-week development period.

The brood comb is usually found in the lower part of the beehive, while the honeycomb may surround the brood area and is found exclusively in the honey supers. When a queen does not have enough brood comb to lay eggs, usually due to congestion from pollen or honey, the bee colony may be more prone to swarm.

Pesticides vary in their effects on bees. Contact pesticides are usually sprayed on plants and can kill bees when they crawl over sprayed surfaces of plants or other areas around it. Systemic pesticides, on the other hand, are usually incorporated into the soil or onto seeds and move up into the stem, leaves, nectar, and pollen of plants.

Of contact pesticides, dust and wettable powder pesticides tend to be more hazardous to bees than solutions or emulsifiable concentrates. When a bee comes in contact with pesticides while foraging, the bee may die immediately without returning to the hive. In this case, the queen bee, brood, and nurse bees are not contaminated and the colony survives. Alternatively, the bee may come into contact with an insecticide and transport it back to the colony in contaminated pollen or nectar or on its body, potentially causing widespread colony death.
