In May 1852, August von Berlepsch in Germany designed a movable frame. [2] On October 5, 1852, in the United States, L. L. Langstroth patented a new hive with movable frames under US patent # US9300A. [3] [4] Today, the Langstroth hive is the most common design in many parts of the world. In the UK the national hive is more commonly used.
Among his most important inventions was a hive frame in a separate honey chamber of his beehive. He also invented a crude queen excluder between brood and honey chambers. [ 6 ] [ 7 ] Petro Prokopovych was also the first to ever model a 'bee beard' after delineating and calculating 'bee swarm behaviour", inspiring students for generations.
Other inventors, notably François Huber in 1789, had designed hives with frames (the so-called leafe or book hive), [3] but Langstroth's hive was a practical, movable frame hive, which overcame the tendency of the bees to fill empty spaces with comb and to cement smaller spaces together with propolis.
In 1838 he devised a movable-comb beehive, which allowed manipulation of individual honeycombs without destroying the structure of the hive. The correct distance between combs had been described as 1 + 1 ⁄ 2 inches (38 mm) from the center of one top bar to the center of the next one. In 1848 Dzierzon introduced grooves into the hive's side ...
The brood of Western honey bees develops within a bee hive. In man-made, removable frame hives, such as Langstroth hives, each frame which is mainly occupied by brood is called a brood frame. Brood frames usually have some pollen and nectar or honey in the upper corners of the frame. The rest of the brood frame cells may be empty or occupied by ...
The Leaf Hive, invented in Switzerland in 1789 by François Huber, was a fully movable frame hive, but had solid frames that were touching and made up the "box." The combs in this hive were examined like pages in a book. Langstroth read the works of Francois Huber and Edward Bevan and obtained a Huber leaf hive in 1838.
Based on the aforementioned measurements, August Adolph von Berlepsch (Bienezeitung May 1852) in Thuringia and L.L. Langstroth (October 1852) [29] in the United States designed their own movable-frame hives. Langstroth used, however "about 1/2 inch" (13 mm) above the frame's top bars and "about 3/8 inch" (9.5 mm) between the frames and hive body.
Even in a normal hive, about 1% of workers have ovaries developed enough to lay eggs. However the usual number of the laid eggs is very small. Only eight eggs (seven moderately and one fully developed) were found after examining of 10,634 worker bees [2] (strong colony contains about 100,000). Workers eventually lay significant numbers of eggs ...
