Dadant

Charles Dadant emigrated from France to America in 1863. He invented the original Dadant hive which accommodated 10 large frames.

The Modified Dadant (MD) was developed in 1917 from the original Dadant hive and consists of a larger brood box to accommodate 11 slightly smaller frames which are similar to those used in the Jumbo Langstroth hive.

This arrangement gives 93,500 brood cells, making the MD hive the largest standard hive in use in this country. The external dimensions of the brood chamber are 20” x 18½” x 11¾” high, and like the Langstroth, the MD is top bee space with the short lugged frames resting in a rebate cut into the thickness of the narrower sides. Note that the Dadant brood frames are at 1½” spacing (38mm).

Shallow frames are 6¼” high and a super will hold 11 Hoffman frames or 10 Manley frames.

Brother Adam at Buckfast Abbey in Devon designed the Buckfast Dadant hive in the 1920s. This consists of 12 standard Dadant frames in the brood chamber and is bottom bee space. The sloping roof design throws off rain water more efficiently than a flat roof but still maintains a flat surface for resting hive parts on (see diagram). When taken to the heather the hives are held together with a metal rod down the centre.
Four of these hives are placed in a square pattern with the entrances oriented north, east, south and west with the beekeeper working the hives from the centre of the square.

News & Events

Bees force plants to flower early by cutting holes in their leaves
Hungry bumblebees can coax plants into flowering and making pollen up to a month earlier than usual by punching holes in their leaves.
Bees normally come out of hibernation in early spring to feast on the pollen of newly blooming flowers. However, they sometimes emerge too early and find that plants are still flowerless and devoid of pollen, which means the bees starve.

Turkish beekeepers risk life and limb to harvest ‘mad’ honey
Mad honey, known to the Greeks and Romans, is still produced in small quantities by beekeepers in parts of Turkey where indigenous rhododendron species make a potent neurotoxin which ends up in local honey.Read the article.
Pesticide made from spider venom kills pests without harming bees
Funnel-web spiders have neurotoxins in their bite that can kill an adult human yet they might turn out to be our allies if the small hive beetle ever reaches the UK.
Scientists at the University of Durham and Fera Science think the spiders may provide the weapon we need to stop the beetles.
The spider venom contains a cocktail of ingredients and one of them – Hv1a – is toxic to most insects, including the small hive beetle, but does not seem to affect bees or humans.
Hv1a needs to be injected to be effective. Just swallowing the toxin is ineffective as it is degraded in their gut. To get round this the team have bound Hv1a to a molecule from the common snowdrop which effectively carries it through the gut barrier.
In the laboratory the team fed the “fusion protein” in a sugar solution to beetles and their larvae. Within a week, all the beetles and larvae were dead.
Next step was to put beetle eggs on bee comb with brood, and spray with the compound. The honeycomb and bees survived virtually untouched, but most of the new beetle larvae died.
