Bee Hive Introduction

A hive is a structure in which a bee colony lives.  Managed bee colonies are housed in hive boxes that can be stacked to provide additional space for the colony and its honey as it expands.  The boxes are constructed using uniform dimensions so frames can be interchanged between boxes and hives as necessary.  

The photo above depicts two production colonies (left and right), two nucleus colonies (narrow white boxes) and an occupied swarm trap from which the frames are about to be moved into a hive box in our apiary (center).

A nucleus colony or "nuc" is a small colony of bees (typically 5-10 frames of worker bees and a queen), which is a resource hive in the apiary.  The smaller hive box makes it easier for the smaller bee population to control temperature and humidity within the hive and manage pests.

Nucs have many uses, including queen raising and breeding, production of additional brood to bolster weaker hives, management of swarming by splitting strong production hives, and overwintering new colonies for replacement/expansion in the spring. 

Our honey production colonies are housed in 10-frame boxes.   A typical production colony consists of two 10-frame deep boxes (yellow boxes in image above).  Bees use the deep boxes for pollen storage and raising of brood.  

During the spring and summer nectar flow, shallower boxes called "honey supers" are stacked above the brood boxes (white box in image above).  Bees store nectar in the supers and convert or cure the nectar into honey.  Supers are removed to harvest honey, then the bees store honey in the brood boxes as their winter food supply.

Managed bee colonies are raised using removable frames.  The frames are typically made of wood or plastic on or within which bees make or "draw out" wax comb.  The cells of the comb are used for raising new bees or brood and for the storage of pollen, nectar and honey. 

Bees will fill nearly all open space with wax comb or will seal or glue together smaller spaces with propolis, a  resinous material bees produce by mixing wax, saliva and sap collected from evergreens.  To facilitate inspection and management of hives and minimize damage to the comb, all bee hive components are designed using a concept known as "bee space".  Bees prefer to leave approximately 9 mm (3/8") space between surfaces to allow free passage throughout the hive.  Smaller gaps limit bees' use of that area and lead to propolizing, while larger gaps are filled with "burr" or "brace" comb.  Thus, all hive components (boxes, lids, frames, etc.) are designed to maintain bee space between them so they can be removed and inspected.  

The population of a bee colony consists of a single queen, female worker bees, and, during the spring and summer, male drones.  At its peak in the summer, a 10-frame hive may contain 50,000 or more bees, most of which are workers.

The queen generally only leaves the hive once--to be bred shortly after she emerges as an adult bee.  She then resides in the hive, where she can lay 1,500+ eggs/day during the spring and summer.  

Worker bees perform all other daily functions in the hive.  They produce wax and propolis, build comb, feed eggs and larvae, feed and attend to the queen, clean cells for reuse, remove debris and dead bees from the hive.  Workers are also the pollination "workforce" as they forage for pollen and nectar.  

Drones are produced in the spring and summer to breed virgin queens.  Worker bees exclude drones from the hive in the fall to reduce the colony population to be sustained through the winter.

Bees collect nectar and store it in cells in the "honeycomb".  Bees cure nectar by evaporating excess moisture.  When nectar has cured into honey, bees protect it by capping it with wax (top of image above).

Pollen is an important source of protein and is also collected by worker bees.  Bees store pollen in the comb near areas used for brood (orange and yellow cells in the center of image above). 

A bee's life cycle consists of four stages of development: egg, larva, pupa, and adult.  Worker bees develop from an egg to an adult in 21 days.  The queen lays a single egg in each cell of the comb.  Fertilized eggs develop into worker bees; unfertilized eggs develop as drones.  Eggs and larvae are fed by the workers in uncapped cells.  Once the cells are capped, the larvae transforms into a pupae and then into a adult bee.  Capped worker brood and uncapped larvae are visible in the bottom center of the image above.    

Hives are split and less productive queens are replaced using the "On-The-Spot" or OTS method of queen rearing developer by Mel Disselkoen.  This involves removal of older queens to a nuc box, notching or compressing the bottoms of cells just after eggs hatch, and management of resulting queen cells. 

Queen cells capped in a full hive are moved to a queen castle, which is a deep hive box divided into compartments with separate entrances.  Each compartment requires only 2-3 frames and provides an efficient space for new queens to emerge, mate and begin laying.  

After the new queen is laying, the 2 frames in a compartment of the queen castle are moved to a 5-frame nuc box to provide room for additional brood and pollen and nectar storage. 

Queens lay 1,000+ eggs daily, each of which will be a new bee in 3 weeks. Nucs started in April outgrow their 5-frame boxes and are moved up to 10-frame boxes. 

Black locust and tulip poplar, two of the principal nectar sources in our area, bloom in May, along with blackberry, black cherry, autumn olive, and lilacs.

The very busy bees are returning to the hives with pollen and nectar dawn to dusk. 

Hives get a 1-1/2" shim to provide provide an upper entrance for ventilation to carry humid air out of the hive.   Foam insulation is placed under the outer cover to reduce potential for condensation, which could drip onto and chill the clustered bees.

Mice like the protected, dry and slightly warmer environment of bee hives as much as they enjoy houses and garages.   Hive entrances are reduced to <1" and screened to exclude mice. 

After the honey supers are harvested, the hives are treated to control Varroa mites, an external parasite that feeds on honey bees. Mites spend most of their lives inside capped cells with developing bees, so hives are treated again in late November or early December when hives have the least amount of brood.
