Course Notes – Week 5 – Pests & Disease

Week 5 – Pests & Disease

How to recognise a healthy brood.

  • Eggs – 1 to a cell and in a pattern and blocks (not random).
  • Larvae – pearly white (glistening), curled in a ‘c’ shape, moist and segmented (like an orange).
  • Sealed Brood – honey coloured, doomed caps, no holes/gaps and dry.

Pathogens – these spread horizontally via sharing food between bee to bee. If a bee dies in the hive, they will carry the bee out of the hive. Vertically is where spread from the queen but this is very rare.

Notifiable Disease – if you find these you must notify the National Bee Unit. These include American Fouldbrood, European Fouldbrood, Small Hive Beetle & Tropaelaps (these last 2 are not in the UK).

American Fouldbrood

European Fouldbrood

  • This is bacteria
  • It affects the larvae pre capping
  • Larvae is a yellowish brown and appears melted and they lie in a unnatural position
  • The bacteria is growing in the cell and feeding on the food.
  • Larvae can grow into an adult bee if sufficient food.
  • Inform Bee Inspector who tests for EFB.
  • If early states then they may suggest antibiotics or take the bees off the frames.
  • If far gone – will have to destroy everything. EFB

Frequency – very rare.

  • AFB – 2013 was the last incident
  • EFB – 2014 – 1 and 2015 – 2.
  • A bottling plant in Histon imports honey from China and China doesn’t destroy AFB. Bees will eat the honey in the empty crates and carry it outside of the plant.

How prevent –

  • clean kit
  • wash gloves in between inspections.
  • Look for diseases specifically at beginning and end of season
  • Don’t swap frames and boxes
  • Don’t feed honey from another hive
  • Wary of second hand equipment
  • Be wary if swarms from unknown origin

What to do

  • Rope test – The “rope” test is where you put a matchstick in the sealed cell and the contents comes out as a “rope”. I find that just putting it in and removing it doesn’t always work, you need to twist or stir it a bit.
  • Ask experienced bee keeper
  • Don’t take them to another bee keeper
  • Don’t move

Varroa 

  • this is no longer a notifiable disease and you will end up with it in the colony.
  • http://www.nationalbeeunit.com/index.cfm?pageid=93
  • Parasite mites
  • Bite into the cuticle and feed off the equivalent of the bee brood.
  • Breed in capped calls (preference drone cells)
  • Doubles in population every month – especially in active season
  • Lives 2-3 months and population grows quicker than the colony
  • Not easily visible.
  • When varroa population is high – it can lead to a colony collapse.
  • Aim is to keep the population as low as possible.

How manage

  • chemical and bio technical
  • open mesh floor – put tray underneath and this will collect the dead mites.
  • Page 34 – Managing Varroa Booklet
  • Apiguard – don’t use when got honey supers as honey will smell. Put on as soon as honey taken off (end of July/early august). Its effective when warm.
  • Alt – Mike Away Quick Strips. Very new so best to wait and see how successful.
  • Varroa doesn’t kills bees but they spread virus. There are currently 18 identified. All similar strands. Nothing able to do – just more stressed skills are more affected.

How know if effected –

  • deformed wings (appear melted)
  • trembling flightless bees
  • deformed ‘k’ kings – wing not tucked in when wandering
  • Shiny/hairless bees
  • bloated abdomens.

Course Notes – Week 4 – Swarming & Feeding

Week 4 – Swarming & Feeding

Swarming – 

Why – creates a new entity and colonies.

Looks like – huge cloud of bees and make lots of noise – constant hum. The will initially settle near the hive and then a few hours later they will find a permanent home.

Prime Swarm – this is the original queen with new bees. Usually April – July and it’s when a new queen cell has been capped.

Caste Swarm – a new queen and has left the hive with some bees. Usually after the prime swarm.

Triggers – overcrowding with lack of space, ventilation, too many nurse bees or too many wax (means they are bored) or lack of queen pheromone.

Important to recognise 3 types of queen cells.

Emergency queen cells – if there is no queen then the worker bees have 4 days to convert a cell into an emergency queen cell (queen cell on front of comb). DO NOT KILL OR DESTROY. Close up the hive and leave for 3 weeks. Note – there can be lots of these.

Old Queen – supercede the queen as she is not working as well. The comb will have been eaten around it. Leave it to get on with it.

Good Young Queen – queen cups develop. See them hanging down. These are done for swarming and will be at the bottom of the comb. It caught early enough them destroy. If there are no spare cells in the frames then there is a risk of swarming.

Prevent –

inspect 7 day intervals in swarming season and aim to find queen cells before they are capped.

There will be an increase in drones.

Put a spare super on to give more space (or 2nd brood box).

Ventilation – not necessary in mesh floors.

Catching

Catch them in a cardboard box. Shame the swarm or spray with water and they fall towards the cardboard box. Make sure there is a cloth over the box for them to fall into.

Leave them on the cloth until dusk. Tie sheet around the box and take to the hive.

Put sheet in front of hive and then bees walk up sheet to the hive.

Food & Feeding

Forages bring in pollen, nectar, water and resin to the hive.

Nectar – combination of sucrose and water (can be 80% water). It is converted into honey. It is passed to worker bees and put into cells. The water content needs to be reduced to 17-19%.

Bees prefer high sugar content and will ignore apples trees for oilseed rape.

Colony need 50kg of honey p year so need to up 200kg. Each bee will collect 20-100mg of nectar per flight).

Need to leave 17kg of honey to get them through the winter. They produce 27-68kg surplus honey.

Pollen – it has protein including fats and vitamins. they used the pollen to feed the larvae and creates brood food. Pollen is stored around the brood areas. If there is lots of pollen then it is a good sign of a healthy queen and hive. Need 25kg pollen each year.

Resin – use resin to make propolysis (bee glue). It blocks gaps in have and is mildly antiseptic.

Water – used to dilute honey to make it usable. Need water supply near the hive.

To feed –  get a bucket and put sugar in. Mark the bucket on outside and keep gradually adding water until it reaches the mark on the bucket.

 

Course Notes – Week 3 – Where & Manipulation

Week 3 – Where & Manipulation

  • Where to put the hive:
  • It needs to be a semi permanent place as if it needs moving it can move less that 3ft or more than 3 miles. If it is moved more than 3ft then there is a risk that they won’t find the hive. You can move the greater distance but gradually with 3ft intervals.
  • Weight – 30lb initially but will end up being 150lb.
  • Base- Stable base that won’t sink into the ground. Ideal is paving slab. Height so that the top of the brood box is the same height as clenched fist when standing up straight. Pallets, milk crates. Advisable to have base for 2 hives so use the space to put brood boxes/supers down when working on the hive. You will work on the hive from the back. The front needs to point in the direction of where you want the bees to fly out to forage. Pointing East is ideal
  • Needs to be bright and light – queen start to play earlier in the season.
  • Need to have access from a wheelbarrow.
  • In an area where food is available – variety of types of flowers,
  • Water source – ditch, dirty stagnant puddles
  • Don’t point front of hive in direct of where lots of people will be. Bees needs to get above people. Screen – around sides and front – 3ft away – can help them fly up.
  • Wind direction – so now blow into the hive.
  • Avoid frost pockets (bottom of hills near trees).
  • Not underneath trees – tree roots will be under hive so roots will move the hive slightly and bees end up using more propolis. Also tress will drip on the hive.
  • Not under high voltage electric cables – bees will pick up electric signals/field and makes them angry. They can pick up underground cables as well. Need a distance of 100 yards. Phone cables – not idea but not as bad.
  • Animals – very few attack hives. Badges are the only possibility. Deer – will rub their horns on the hive. Chickens – not running around the hive as will peck at the hive and the bees. Most home pets are not an issue.
  • Flooding – avoid such areas as bees die during floods.
  • Footpaths – you have a duty not the cause a nuisance.
  • Distance from home – 10ft is the closest but point away from the house.
  • Mowing lawn – likely to attract bees but wear veil if mowing close (less than 10ft)
  • Wind – need different orientation of hives if have several in a row. Wind will cause a little bit of drifting and may cause bees to go to a different hive.
  • Frames direction – front to back is the cold way. side to side is the warm way. Doesn’t matter – just whatever is more comfortable.
  • In windy conditions – put a risk or stone on top.

Manipualtion

  • Best to do on warm calm day – not on a windy and cold day
  • Put veil on after smoker lit.
  • Have more than one way to light a smoker.
  • keep puffing smoker so they don’t get out. Puff smoke in entrance and wait.
  • At The Hive Entrance book – useful and free to download.
  • Roof off – if bees are coming through the hole on crownboard then smoke them.
  • Put smoke in super .
  • Once super off – drift smoke across queen excluder. Take off excluder – check queen not in it, Do this over the brood camber. Place excluder leaning against the hive front. If bees coming out of brood box then drift smoke over.
  • Look for – queen, eggs, swarming (queen cells) enough store of honey and pollen, enough space in brood box for laying eggs and nectar, disease. Look on both sides of frames. Must put frames exactly the same way and order. Keep a hive record of what seen.

Course Notes – Week 2 – Biology of a honey bee.

Week 2 – Biology of a honey bee. 

Bees can see colour violet,  blue, green and are able to see in ultraviolet.

They have ‘plan polarisation – this enables them to find water, It also enabled them to just look at tiny pattern of sky and able to instantly know where the sun is.

Stomach – called honey stomach as this is where they store the nectar.

Feeding – eat sugar and nectar.

The collect pollen all over the their body and use their legs to get back to hind leg – their pollen basket.

Queen – has  a large abdomen and will only sting other queens. Lives for 3-5 years and derived from the same egg as a worker but is fed on royal jelly. Cells are large to give more space to grow.

Drone – large eye and chunky thorax. Live for 50 days and die once mated with queen. They are kicked out of the hive in the winter.

Worker – they live for 6 weeks in summer and 6 months in winter. They spend 3 weeks in the hive, 3 weeks foraging and flying.

Brood – need to be looking for new eggs as this shows that the queen has been there s the past 3 days. Look for cells to have larvae. Multiple eggs in cells is not good.

Need to have half brood open, half brood capped. If lots of eggs then probably creating queens. If lots of capped but not many eggs then queen is not laying.

Wax – nectar makes wax. Max honey production – able to feed lots so that they are able to produce wax easier. .

Smoking – this simulates a fire and calms them. Promotes them to feed up on the food in the hive – keeps them occupied and if they are full of food then harder to sing.

Bee space – 6-9 mm wide

Moving hive – less than 3 feet or more then 3 miles.

Replace the brood every 3 years.

 

Course Notes – Week 1 – The Hive Equipment

Week 1 – The Hive Equipment

Need to join beekeeping association – gives you insurance, meetings and able to borrow eqpt.

Winter – feeding bees by under the top cover put a bag of fondant icing over the round hold with a cut in the plastic bag).

A colony – `1 queen with 20-80000 workers & 0-2000 drones.

Clothing – Gloves (leather or hide), Veil or jacket with veil built in, trousers and tuck into wellies.

Eqpt – smoker & fuel, Hive tool.

smoker – need fuel for example hessian sacking, wood or cardboard pellets. Rotten wood is ideal- willow trees or dried out wood  that is 2 inches long.

The National Hive – consists of

  • floor

This is not put on the floor but on a stand,- eg concrete blocks or milk crates. The stand needs to be able to taken 150lb in weight. Height of the brood chamber should be where your clinch fist is when stood straight. Floor includes an open mesh floor but you can add a ramp.

  • brood chamber

This will have 11 frames.

  • queen excluder

plastic or pressed zinc.This will come farmed but if not then just need to be aware of bee spaces

  • 2x honey super

these go onto of the brood box with the frames going in the same direction (see week 3 for cold or warm way)

  • coverboard

This could be glass to enable you to watch the bees, The holes are for where you put the fondant icing.

  • roof

Time commitment – October – March is very limited. April – July – 15 mins p hive every 7-10 days but be aware that initially it will be 1.5 hours.
