Beekeeping and Honey!
Losing a hive July 29 2014, 0 Comments
All the books and blogs tell you that you will loose a hive. They all say it will happen to you at some point: either by some mistake you make, from starvation or dehydration or some catastrophic failure from an outside factor...
Well, this last week it happened to us. And it really sucks.
We were finishing up our winter inspections of the various sites around Perth surrounds, and had headed out to site. The hives seemed a bit quiet, and even the property owner had commented on how quiet one hive seemed. After we set up the table, equipment and lit our smoker, we opened up the first hive. The super was pretty quiet, and as we started looking into the brood box we knew there was a problem. There was almost no brood (larvae that has been sealed off to metamorphose into bees). What brood was there was scattered and there was almost no lavae and NO eggs. We saw the Queen on the third frame and she looked well - the workers were deferring to her when she stopped walking on the frame. If the workers had rejected the Queen they would be either aggressive to her, or ignore her when she walked close by.
We quickly closed up the box after inspecting the other 7 frames and put the super back on. We decided the leave the super on for the time being because we were uncertain about why the Queen wasn't laying.
Over to the other quiet hive, and we only saw a couple of bees go in and out. The moment we opened the super we knew something was very wrong. The smell was unusual - stale and slightly musky - and along the tops of the frames, instead of the usual small amount of free comb and propolis, there was wax moth. Alot of it. With a sinking feeling, we pulled out a couple of frames there was no presence of bees on the frames. Pulling the super off, the brood box was worse - no bees and full of wax moth eggs. No signs of diseases, no mess on the bottom board, and less than 100 bees.
With the weakness in the first hive, and this hive completely gone, we packed up, gave a brief explanation to the property owner and decided to go directly to our Guru Beeman and ask his advice. On the way there, I Googled wax moth to find out why it was present in the hives. Having only read about it in books, seeing it reality was terrible and I couldn't remember whether it was a cause of hive failure or a symptom. It turned out wax moth can only gain a foothold in a hive that is severely weakened or dying. They will take advantage of ill health and slow/non present guard bees. The moth will lay eggs in the comb, and use comb and honey to develop from egg to moth.
After explaining the history of the hives, and the current situation of the hives, our Beeman told us that in his opinion; it was 99% certain that an outside factor was responsible for the demise of the hives, namely chemicals. Although it was a strong hive by the end of summer, this particular hive had a small die off in the summer, and another last spring. It recovered from both of these, and after explaining to our Beeman what the die-offs were like, he told us it was certainly not dehydration (as we had assumed) but over exposure from poorly applied pesticides. He explained that with some pesticides, the guard bees can smell it on the forager bees, and won't let them back in the hive. Others they can not smell on them and that is how they make their way into the hive (or they have been ingested and are laid down into the honey). Very soon, the Queen is exposed to a chemical and if she is damaged, the hive can die within 3 weeks. Sooner if the chemical is actively killing off the bees. If the bees brush up against the chemical, they will pass in onto many bees inside the hive if they are allowed to walk it back in, because bees are very tactile. They crawl all over each other - they clean each other and walk over each other and even pass nectar from themselves to other bees (like mother birds feed baby birds). This is why diseases and chemicals spread so easily within a hive.
This all happened quickly, within a few weeks and these strong hives have become extremely weak hives. Our Beeman listened carefully to our story and told us that in his experience of decades of beekeeping he had had more problems with pesticides in 'hobby' farm areas (or semi-rural) than in full agricultural areas. He suggested that because full-time farmers are more heavily regulated, and better educated as part of their livelihood, they tend to use chemicals differently than hobby farmers. Closer to season, closer to dusk, less liberally (because they have to spend so much money on it!) and if they have pollination services attached to the farm, they move hives away during spraying times.
In any case, Mr Beeman told us to feed up the alive Queen in the remaining hive and try and limp her along until Spring. There are no Queens available to re-Queen with during winter, and we can't weaken another hive by giving them a frame of brood to get them to raise another one. The bees are only producing enough bees at this time of year to maintain enough workers to get to spring. Feeding sugar syrup may entice the Queen to think there is a honey flow and re-start her laying. Mr Beeman also suggested crossing our fingers.
Mr T went out a couple of days later to collect the dead hive and reduce the live hive to one box (less energy to keep 2 boxes warm) and feed up the ladies. He said that there was a small amount of eggs on one frame, so hey, maybe the finger crossing worked...I'll keep you posted...
Cast of 'The Hive' - Part 1- 'The Queen' August 15 2013, 0 Comments
Out and about in the community running our honey stall at markets, I often get asked about who does what in the hive. Questions like 'is the Queen the Boss?', 'what do the boy bees do?', 'how do they produce different flavoured honeys?'...This post is about trying to sum up some of these questions.
The Queen of the Hive is about half as big again as the worker bees. She has a sleek, shiny abdomen that has paired ovarioles numbering about 150 within her large ovary. Some say she is waspish in appearance, as her wings are smaller than a workers', as is her head. However, she does not have any of the waspish tendencies such as twitching and edgy movements.
Once the Queen has hatched from her cell and has done a small orientation flight, she will go on her 'mating flight'. This entails flying around and emitting a 'come hither boys' pheromone. Once the boys do 'hither' along, she has copious amounts of...copulation with as many males as she can (usually about 8-20!). She then heads back to the hive to start her life of Queenly state.
After her day of passion, the Queen becomes pretty much like the Queen of England. She produces a pheromone called the Queen Substance. This is spread around the hive, and basically tells the workers that 'everything is fine, go about your business'. This is very much like the Queen waving at the people from the Balcony- Yes, dears, everything is fine, go back to your lives! [insert calm wave here]. And now she starts laying eggs. Lots of them. Up to 1500 a day in the peak of spring! She doesn't clean herself, or feed herself. The Queen has a retinue of worker bees who attend her, and spread the Queen Substance around the hive, and direct the Queen to comb they want her to lay eggs in. She remains in total darkness (except during an inspection from a beekeeper ;-) and lays eggs for the next 2-4years! When she is judged by the hive (or beekeeper) to be too old, she is deposed, in fact, laying the egg that will be the new Queen... and her own doom!

Winter Prep/ Re-Siting Hives May 20 2013, 0 Comments
Well it has been a very busy time personally and of course, winter preparation for the bees is quite time consuming as well. We have been using some 'spare time' over the last couple of weeks before we move house to do Winter Prep.
This involves re-coating the supers with Lanotec - a bee friendly lanolin based weather proofer, full hive inspections to ensure brood patterns are looking good, queen sightings (presence and health check), checking the bottom boards are clear of debris and a last harvest of any last summer honey to be had (of which we managed to get 6 frames out). We also put two hives back down to just the two boxes (1 brood, 1 super) so they all have a brood and one full super full of honey over the winter period.
Over the winter they tend to 'maintain' the honey stores rather than rely totally on the stores, but you can never tell how Australian weather will pan out and I like to make sure they have plenty over the wet months. I always try and leave enough so I won't have to feed the ladies sugar syrup, and last year they only went through about 4 frames of their stored honey, so we got off to a good start harvest wise in the spring when we supered up for the spring brood/honey flow.
So with all that done, the next thing to do was to prepare two of our hives for transport to our new site in Chittering. We met a lady a while ago who said she was happy to have beehives on her property of 6 acres backing onto state Jarrah and Marri forest! Last night after the ladies were all home after the lovely sunny day, we tucked the guards in (with only one hiccup for me *sting* insert sad face here!) and strapped the hives together. I have been told a couple of funny (and horrible) stories of highway spills and bees invading cars etc and we both decided that was NOT a good option. Accordingly, we voted for a double strap system!
This morning we loaded without incident, listened to our very angsty ladies who were not impressed that they were locked away, and drove up to Chittering - minus highway escapees!
Upon arriving, we quickly got the stands level and and the hives into place. Having only previously sited nucleus hives before (or swarms that were fairly small), we found the huge rush to get out of the hive an amazing thing to watch! Lots of bees everywhere, housekeeping started and a few guards to let us know they were not amused, who thankfully did not try any funny business with Mr and Mrs L, the lovely owners of the land we were on.
On the way home, we congratulated ourselves on having NO EPIC FAILS on Great Northern Highway, with trucks and motorists mingling with very cross ladies! Go Us ;-)
