Dartington Long Deep Hive

The Dartington long deep hive was developed in 1975 by Robin Dartington, an engineer.

The hives are intended for use in gardens and on roof top locations, not for commercial or migratory beekeeping.

They are designed to keep the weight of individual parts below 7kg (16 lbs), which observes the safety guidance issued by the UK Health & Safety Executive. The hive is therefore safe for use by everyone.

The design is derived from classic log hives used around the world where honey is stored by the bees at the back of the cavity away from the entrance. However, the system is very flexible as the brood chamber can be divided to house two or more colonies plus honey boxes may be added above the brood chamber to provide as much honey storage as required.

Lug length 1½” 1½” 1½”

The construction uses widely available modern materials such as plywood. Essentially, the hive is a rectangular brood chamber based on the National 14 x 12 frame with top bee space.

The hive holds 21 frames (14” wide x 12” deep) with an insulated dummy board front and back. The body is raised to a convenient working height on long legs and supports four or more honey-boxes above the brood chamber each holding five Manley frames or six National shallow frames (14” x  5½”).

A fifth honey-box is provided to allow exchange of a full box for an empty one or it can be used as a queen mating hive.

Accessories include two carry-boxes, each holding six 14 x 12 frames for winter storage. A carry-box can also be used in summer as a nucleus hive using the fifth cover board as a roof.

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.

What’s that Buzz? Plants hear when bees are coming
New research has shown that plants can ‘hear’ sounds around them and flowers respond to the buzz of approaching bees by producing sweeter nectar. The research biologists from Tel Aviv University played recordings of flying bee sounds to evening primrose flowers and found that after a few minutes the sugar concentration in the flower’s nectar had increased by 20% on average when compared with flowers left in silence or submitted to higher pitched sounds.
The authors of the report say that, for the first time, they have shown plants can rapidly respond to pollinator sounds in an ecologically relevant way.
Producing sweeter nectar in response to the sounds of bees can help entice the insects to visit the flowers and increase the chances of its pollen being distributed.
