While the global pandemic disrupts our routines, those who care for livestock, including domesticated honey bees, must continue care without disruption. Patrice Fisher, the beekeeper at Firestone Farm, reports that bees are thriving at the living history farm within Greenfield Village, The Henry Ford, in Dearborn, Michigan, as of 4 June and 6 July 2020.

pandemic – beekeeping – Living History Farm – practical experience – beekeeping tools
Livestock need care daily despite the disruptions of a global pandemic. This includes domesticated honey bees. Beekeepers inspect their hives, monitor the food supply, harvest honey, and treat what may ail members of the colony. Patrice Fisher, the beekeeper at Firestone Farm, shares this report on the condition of hives at the living history farm within Greenfield Village, The Henry Ford, in Dearborn, Michigan, on 4 June and with a 6 July 2020 update.
Beekeepers at Firestone Farm use a Langstroth-type hive to house pollinators at the living history farm that interprets the birthplace of Harvey Firestone and farm life during the mid-1880s. The structures were originally located in Columbiana County, Ohio, but were relocated and reconstructed in Greenfield Village, and opened to the public in 1985. The project included an orchard with historic apple varieties. The bees pollinate the apples and other crops, shrubs, and flowering plants throughout Greenfield Village.
Lorenzo Langstroth observed bee behavior and patented a hive in 1852 that mimicked the spaces that bees created as they built their comb within hives. Langstroth designed a structure that consisted of stackable “supers” into which frames of a standard dimension were inserted, each located a “bee space” from the other. Within this structure, bees constructed their hives to nurture the bee larvae and store their honey food supply.
Firestone beekeepers had three objectives to accomplish during their 4 June hive inspection:
1) to replace
the solid bottom boards with screened boards for better ventilation.
2) to apply a
formic acid treatment for varroa mites. At the last hive inspection on 25
April, beekeepers did a mite count test and determined that #1 hive (closest to
barn) had 8 mites per 300 bees, #2 had 0 mites, and #3 had 4 mites per 300
bees. That’s not terrible but definitely needed to be addressed before the
numbers started increasing exponentially.
3) to add an
additional super with empty frames to each hive to give bees in each hive more
Inspection determined that the bees are doing fabulously. All three hives have a lot of bees and all have surplus honey already during springtime in Dearborn, Michigan. Patrice indicated that “This is the best I’ve seen for this time of the year in the five years I’ve been minding these bees. We were wondering if they were somehow benefiting from the lack of people in the vicinity and perhaps reduced landscaping, resulting in a lot more forage in their territory. Just supposition. We didn’t really look too deeply into the hives; it was obvious that they are all thriving.”
Beekeepers saw capped supercedure cells in every hive (photographs below). These cells were simultaneously attached to the bottom of one super and the top of the one below it. Maintaining the hive requires removing supers, even as this also can destroy some of these cells because the supers must be separated to get to the bottom layer.
The Master Farmer of Greenfield Village, Steve Opp, reported a swarm of bees just before the 4 June inspection. Beekeepers tried to figure out which hive they came from, but it seemed as though they could have come from any hive. They added an additional empty super to each hive to give the bees more room, hoping that increasing the hive capacity will quell the bees’ natural inclination to swarm. Yet, Patrice reported that she is “happy to see swarms even if we can’t catch them – it just means more native bees are being introduced into the environment.”
The Firestone Farm beekeepers returned to
the hives on 6 July 2020, with two goals:
to remove the medicated formic
acid pads attached 4 June
remove the entrance reducer and
take out the solid bottoms from each hive, to improve ventilation.
document the visit and actions
taken in writing
They found the hives buzzing with activity,
and bee “making honey like crazy. The empty supers added last month are already
full, so the keepers added another empty super to each hive, right above the
level where the bulk of the brood was residing” (see notes taken, and location
of new super documented below).
At the end of July the beekeepers will do another sugar roll test to monitor the mites and see if treatments continue having the desired effect. Toward the end of summer, after honey production slows late in July and before golden rod starts to bloom in the early fall, they will harvest some of the honey, probably 3 supers full. Then the bees can rebuild their food supply with pollen from the fall flowers before frost ends the growing season. Beekeepers will winterize the hives late in the fall to help sustain them through the winter season.

Abstracts Slovenia is home to excellent beekeepers and the indigenous Carniolan bee. Beekeeping is one of the oldest traditional activities and an important part of Slovenia’s identity, natural and cultural heritage. It is a kind of a national hobby; there are 5 beekeepers per 1000 inhabitants in a population of just two million, together around 11.000. The Slovenian landscape is adorned by nearly 14,000 apiaries, containing around 200,000 hives with bees that collect quality honey and other products.
Slowenien ist die Heimat exzellenter Imker und der einheimischen Kärntner Biene. Imkerei ist eine der ältesten traditionellen Kulturpraktiken und wichtiger Teil slowenischer Identität sowie des natürlichen und kulturellen Erbes. Es ist eine Art nationales Hobby; es gibt 5 Imker pro tausend Einwohner bei einer Bevölkerung on gerade mal zwei Millionen; zusamengenommen also etwa 11.000. Die slowenische Landschaft ist geschmückt durch annähernd 14.000 Bienenstände, die etwa 200.000 Beuten enthalten und deren Bienen Qualitätshonig und andere Produkte produzieren.

Beekeeping in the 18th
and 19th centuries was marked by outstanding figures
Successful beekeeping has always been based on
thorough knowledge of bees, ingenious beekeeping techniques, dictated by the
local foraging conditions, and especially on the Carniolan bee and its
excellent characteristics. Of key importance to the progress of beekeeping were
several figures, who with an enthusiasm based on great human qualities taught
sensible beekeeping to simple peasants, and at the same time spread their
knowledge about the Carniolan bee and beekeeping to the wider world.
The most outstanding among them was Anton Janša
(1734 – 1773), an excellent beekeeping theoretician and practitioner, and the
first teacher of the subject at the Beekeeping School in Vienna. His birthday,
May 20, was chosen as World Bee Day from 2018 onwards on the initiative of
Another figure highly important for the
development of Slovenian beekeeping was the priest Peter Pavel Glavar (1721 –
1784), the founder of the first beekeeping school in Slovenia. He was among the
first to write a treatise on bees in Slovene.
The Tyrolean natural scientist and physician
Joannes Antonius Scopoli (1723 – 1788) was active in the Slovene territory and
was the first to inform the world that the queen bee mates with drones outside
The great beekeeping expert and first Carniolan bee trader Emil Rothschütz (1836 – 1909) was instrumental to promoting the Carniolan bee.
The pride of Slovenia – the
The Carniolan bee, Apis mellifera carnica, is a Slovene indigenous bee species that
originated in the area of the Balkan Peninsula, and for historical reasons, its
homeland is held to be Slovenia. The species also lives in Carinthia and Styria
in Austria, in Hungary, Romania, Croatia, Bosnia and Herzegovina, as well as in
Serbia; it has been artificially introduced in Germany and in many other places.
Following the Italian bee, the Carniolan bee is the second most common bee species
in the world.
The Carniolan bee has excellent characteristics: it is gentle, industrious, and long-lived, does not stray into other beehives, overwinters well, consumes little stored food, multiplies quickly in spring, efficiently builds combs, thoroughly exploits rich pastures, especially forest ones, has a well-developed cleaning instinct, making it less susceptible to diseases, and is very good at orientation and swarming.
Why do the Slovenes keep
their bees in hives grouped in apiaries?
The principal reason for this method of beekeeping are the AŽ-hives (AŽ stands for Alberti-Žnideršič). Slovenes are very attached to their bees and make sure that they dwell in dry, warm hives, protected against the cold, heat, and bad weather by the apiary’s shelter. Apiaries differ from one region to another and Slovenes are most proud of the Slovene Apiary which has preserved its typical form for centuries. It derives from Central Slovenia and was described by Anton Janša in his book Popolni nauk za vse čebelarje (The Perfect Theory of Beekeeping) in 1772. These apiaries were mostly built by self-taught craftsmen, based on knowledge passed on by their ancestors and enriched with their own experiences, discoveries, and creativity.
The traditional Slovene beehive is thus an AŽ leaf hive. Beekeepers claim that it is the beehive best suited to our climate and foraging conditions. It was introduced by Anton Žnideršič in the early 20th century and is by far the most popular type of beehive, since over 90% of all beekeepers use one of its variants. It is also spreading elsewhere around the world. The AŽ-beehive is very handy for transporting bees to different pastures, as well.
Painted beehive panels are a
specific Slovene phenomenon
The painted front panels of the formerly plain kranjič hives are part of Slovene cultural heritage that almost every Slovene is familiar with. They are a genuinely original Slovene cultural element. After emerging as a genre of folk art, largely created by and for members of the peasant classes, in a part of the Slovene ethnic territory in the mid-18th century, the custom peaked between 1820 and 1880, to decline due to socio-economic and religious conditions in the early 20th century.
Beekeeping in towns
Urban beekeeping is not something new or
exceptional in our towns, but the practice has recently seen a revival around
the world, including in Slovenia. The bees can produce quality and above all
pristine honey in our towns, since there are no areas affected by phytopharmaceutical products. Apiaries, but
more often stands of box hives, are set up on the roofs of commercial
buildings, on balconies, or in gardens.
Beekeeping is above all a relaxation activity for townspeople. It provides them with bee products and contact with nature close to their home, contributing to their well-being and a quality “green way of living”.
Transporting bees to pastures
Transporting bees from places with poor
pastures to better ones, especially forest pastures, is a centuries-old
tradition in Slovenia, which also spread elsewhere in the late 18th
century thanks to Anton Janša.
There are indeed no places in Slovenia that would provide enough pasture for an entire beekeeping season. Transporting bees is above all of economic importance, as it allows beekeepers to exploit the honeydew produced by some insects on plants at different times and in different places. The practice requires special knowledge and skills and these are continuously being improved.
Bees and bee products have a
beneficial effect on people
Beekeepers increasingly adapt their apiaries into apitherapy rooms, where people can inhale the healing aromatic air produced by the hives. Apiaries are thus no longer merely small or large structures protecting bees, but have been turned into refuges for the well-being of body and mind. Bee products like honey, propolis (bee glue), pollen, wax, and royal jelly have a beneficial effect on health, while apitherapy with bee-venom seems to be effective in treating rheumatoid arthritis and other diseases.

Honey was highly important in the Middle Ages. Cane sugar was known in Antiquity, but it was rare until the 17th century, so honey was used in food and drinks, as well as in medical treatments. Remember, too, that wax was needed for civil and religious lighting. We have evidence of all this from medieval texts such as agricultural treatises, encyclopaedias, fable-books and even religious texts, as well as the illustrations in them. They show us a great diversity of beehives in medieval times and deep interest in the insects’ lives.
seem to have been three periods according to the shape and function of
beehives. The first has fixed honeycombs – the bees attach their combs to an
immobile upper wall and this is the only kind used in the Middle Ages. The
second type has movable components added to the upper part of beehives with
fixed combs and it is only subsequently that we see hives with movable frames
appear. Still, the beehives we see in illustrations have a wealth of shapes and
materials that highlight regional diversity and personized craftsmanship, since
peasants made their beehives from their own local resources.
Trunk or box beehives
used in Gaul, tree trunk beehives are fairly rare in medieval images, although
a few appear in Italian illuminated manuscripts, while their widespread use is
attested to in texts from southern France and in Spain. This kind of beehive is
the closest to what bees do naturally, when they set up home in hollow trees.
Medieval written sources tell us that people often harvested a wild forest swarm by cutting out
part of the tree trunk and bringing it back as a beehive. In that case, the
trunk was cut out half-way down to provide a flight entrance.
Of course, there are other cylindrical beehives, always Italian and made of wooden slats or boards side-by-side. On the other hand, although we have much evidence in written sources from Provence, central and southern Italy, Spain and Portugal, of beehives made of a band of cylindrical cork oak off a tree trunk, we have no illustrations of these.
Parallel to trunk beehives, the box beehives so widespread in Greek and Roman Antiquity, seems to exist in nearly all Italian testimony, made of wide wooden boards, although we do not know what kind of wood – conifer, as Columella recommended because they resisted honeycomb moth.* Illustrations of light-coloured beehives might attest to this. Probably derived from a tree trunk laid out on the ground, these parallelepiped hives were always large, seeming to be about a meter long, even 1.5m, and about 1.30m wide. In most of these hives, flight holes were small, but there were many of them and they seem to be made of two movable partitions. Pliny mentioned “the cover should penetrate the hive, if the hive is too large or if the honey harvest is too small, for fear that the bees will be discouraged and not work well, then it can be made smaller, so that they are fooled about how much their work has progressed.
The beehives we see the most often in medievial illustrations are made of wickerwork woven wattle or split-wood. This kind of basketwork, which was used in Roman times, continued in Gaul and was widespread in the Middle Ages – we see it in illuminated manuscripts in England, northern France, Flanders or in the Rhineland, whereas we hardly find them in more southern manuscripts.
can see several types in these illustrations – some have a ribbed outside of
woven wattle over a framework, without any visible coating, so insulation from
heat and wet must have been poor. However, this woven surface was more frequently
covered with a brownish coating, which matches the written sources indicating
the use of cow pats, as in Antiquity, as the most common covering.
All this kind of beehives, usually about 50 cm in height, were woven over a wickerwork frame: a barked branch was split into several bundles for the vertical stays the wattles were woven around, usually with 8 to 12 ribs and sometimes these ran down to the bottom to make short feet, unless the bottom had a loop around it for the flight hole. The often golden colour of the wattlework does not enable us to see if they were made of oak, hazel, osier or clematis, as suggested by the texts.
beehives came in many shapes, some of them like a small dome with a flattened
top, others conical with a narrow top like a sugarloaf. It is rarer to see a
trunk-shaped hive with a flat top or a bell shape. Most of these hives had a
handle formed by the end of the branch under the woven framework, which made it
easier to carry and to attach the winter covering of straw.
of these hives are illustrated without a flight hole, but most of them have a
small opening in the lower part where the basketwork is looser or in the wooden
hoop between the sides and the base in the form of a small arch or rectangle.
Only conic or bell-shaped baskets have a hole in the lower third in the form of
a narrow slit.
are less frequent than the basketwork hives, and most are found in manuscripts
from northern France or Flanders and entirely missing in southern, especially
Italian, documents. This is due to the fact that they are connected with
cereal-growing, especially rye in more northern areas.
kind of beehive is mainly made of eight to 10 rows of light-coloured straw
twisted into rolls. Depending on the source, this is mainly of well-dried rye
straw, the stems of which are far longer than those of other cereal grains, put
together in rows and linked up with vertical osier (water willow) ties
Straw hives are usually dome-shaped and fairly small, hardly over some 40 cm. They may be capped by a round or stick-like handle, but most of them have none, in contrast to the wattle hives. They usually have a flight hold at the base, a simple arch in the straw, and more rarely, a rectangular slot in the lower third.
Written and ethnographic testimony tells us that these basketwork or straw beehives had a central cross to hold the swarm at the beginning of the comb construction and they could be open at the bottom for work on the colony.
This diversity of medieval beehives shows us the privileged relationship of human and bee at all times, even if the Middle Ages especially prized beehive products in the domestic economy. This is confirmed in the 14th and 15th centuries by permission for Royal, religious or secular lordly appointment of a bigre, a specialized forestry expert responsible for capturing, for his lordly masters, wild swarms of bees and putting them into productive beehives.
