Happy Halloween

Ok maybe this is getting out of hand:  I am dressing my dog as a bee for Halloween.  She is quite proud of herself, especially when we make a big fuss over her.

Bee safe out there ya'll.

Air circulation and feeding in winter


LESSON 66: Screen Bottom Boards In The Winter & Fall & Winter Feeding
In a previous lesson, I shared several approaches on how to prepare for winter. In this lesson I want to go into more detail about screen bottom boards and winter feeding.
Bottom Board 001Screen bottom boards prove to be very beneficial in the summer for reducing mites and for increasing ventilation. But do they pose a threat to a colony during the winter? That's a debated issue. Some cover their screen bottom boards while others leave them open. A few years ago, we did a simple test. We placed covers over 3 colony's screen bottom board and left the others open. We lost all three that were covered. So we always leave our screen bottom boards open all winter. It is our opinion that an open screen bottom board cuts down on excessive moisture. Cold air sinks and warm air rises, so the threat of an open screen bottom board, in our opinion, is minimal.

If your hive is up in the air 6 or 8 inches, then you want to prevent cold wind from curling up and blowing onto the cluster. This can be accomplished by building a wind block around your hive.

Remember, that a winter cluster warms only the cluster and not the inside of the hive. On an extremely cold night, the air several inches away from the cluster will be the same as outside the hive. The bees consume honey, and vibrate by flexing their muscles to generate heat, much like we do when we shiver. That heat is transferred throughout the cluster. They will be able to accomplish generating the cluster heat with or without the screen covered.
Many beekeepers allow their colonies to become extremely undernourished. Pollen and stored honey is essential to winter survival of colonies. In the fall, I work to beef up my colonies. It's tricky for me because of the number of colonies in one location. Even an inside top feeder can create a robbing frenzy. In the fall, boardman feeders placed in the front of hives is a certain robbing disaster.
So my approach is two fold. 1) During the fall only, after most nectar is no longer available, I want to prevent robbing, and 2) I want to beef up my colony nutrition for winter.L662
You can click on the images for a larger view. My approach is simple. I do use boardman feeders, but I place them on stands throughout the bee yard. And on dry days, I pour dry pollen out on the feed stands. My sugar mix is two parts sugar and one part water for fall. I have to make the holes bigger in the lids for the syrup to pass through. I also add one teaspoon of Honey-B-Healthy. Also, notice the bees on top of the jars? I make sugar patties too. L661I mix sugar syrup with powdered sugar until it mixes a little stiffer than play dough. The bees love these sugar patties. I placed one on the top of each jar as you can see in the picture.
So my fall feeding consist of dry pollen, hard sugar patties and 2:1 sugar syrup. Several people have asked me what 2:1 sugar means in measurements. I fill a gallon jar with between 32-48 ounces of very hot water. Then, I add sugar until it reaches the top which is around 7-8 pounds. Then stir it up. I will continue this type of feeding until the bees are clustered for winter.
l667Another very effective winter feeding method is to make the sugar patties I mentioned above and lay on the tops of frames just above the cluster. Because it is a solid sugar feed, you do not have to worry about it freezing. The heat of the cluster will keep it warm and eatable.

l665As the weather warms up above freezing, you can place pale feeders in the hive. I sometimes place jars of sugar water over the inner cover hole and then place a deep hive body without the frames so that the bees can consume the sugar water when it warms enough for the bees to break cluster. The deep hive body serves as a spacer around the jar. The top cover goes above the deep hive body spacer.
l666Another important feed application is that of internal pollen patties. If pollen sources are low within a colony, brood patties should be placed above the cluster. Again, on warmer winter days, the cluster will loosen enough so that bees can feed upon the pollen patties which contain a pollen substitute allowing the bees to consume the protein, vitamins, lipids and amino acids they need. ALWAYS leave the wax paper on the patty. The bees will eat around it, and usually they consume the paper too. If you remove the wax paper, the patty can become moldy and too gooey and fall between the frames.
We do sell the sugar patties, pollen patties as well as the screen bottom boards. Give us a call if you need these items or other beekeeping items.

Corn Syrup linked to bee colony collapse

An important new scientific study on the toxic effects of feeding high fructose corn syrup to bees.

Government researchers have found that high-fructose corn syrup, which is used as a sweetening agent in thousands of products, creates potentially dangerous levels of a toxic substance when heated.

The scientists – from USDA’s Agricultural Research Service in Tuscon and New Orleans and at the University of Wisconsin – were searching for a possible cause of Colony Collapse Disorder, a mysterious disease that has killed at least one-third of the nation’s commercial bees.

The team targeted the popular sweetener because it is widely used both with honey bees and those used primarily for vital crop pollination.

High-fructose corn syrup is produced by grinding corn to produce corn starch, then that powder is processed to yield corn syrup, which is almost entirely glucose. Enzymes or proteins are then added which changes the glucose into fructose.

It is the fructose that food producers use to sweeten their products and by commercial beekeepers to strengthen their bees, to increase honey production and as a food supplement when natural sources of nectar and pollen have diminished.

During repeated tests, the researchers found that when the HFCS is heated it forms hydroxymethylfurfural or HMF which can kill honeybees. Alarmingly, they found when temperatures rose, levels of HMF increased steadily in proportion.

The study, by Blaise LeBlanc, Gillian Eggleston and their colleagues, is published this week in ACS’ Journal of Agricultural and Food Chemistry. The authors said their work could also help keep the substance out of soft drinks and dozens of other human foods that contain HFCS.

“The data are important for commercial beekeepers . . . and because HFCS is incorporated as a sweetener in many processed foods, the data from this study are important for human health as well,” states the report which was funded by the National Honey Board.

Laboratory studies in Sweden published this year have linked HMF to DNA damage in humans, the USDA team reported. In addition, HMF breaks down in the body to other substances – daughter metabolites ­– potentially more harmful than the original substance.

For close to a decade, researchers throughout the world have been searching for the cause of the widespread destruction of bee colonies.

In the U.S., the growing shortage of honey has caused the increased importation of foreign products, much of which is wrongly labeled to avoid paying tariffs on Chinese honey. Some are adulterated with illegal antibiotics on violation of FDA regulations.

Autumn beekeeping

Who would have thought that a hand full of powdered sugar would make a hive of bees so mad. Well it does.

My amazing beekeeping mentor and fellow journey-woman beekeeper came over to help me ready my hives for winter. I had been feeding the girls sugar syrup (2:1 sugar to water, pretty gooey) for about a month now.

We found that the girls have been quite industrious in converting the syrup to honey and if I keep at it over the next few weeks they hopefully will have enough food to get through the winter. Remember, since these are first year hives, I did not take any honey from them this year. Also both of my hives swarmed (one in May, the other in July), which set them back a bit in honey production, so winter starvation is a real threat for them.

To check for varroa mites I had put in a card board grid that slides in under my screened bottom board. Varroa mites are perfectly horrid little parasitic insects that not only fix themselves on adult bees and suck life fluids, but also get into the sealed brood and suck on the baby bees. And it is here that they do real damage; in addition to depleting life resources, the mites also can transfer diseases to the bees.

We found that - no surprise - both of my hives have mites. Almost all hives in North America (and in most of the word) do. But in one of my hives - Kathryn - a few of the bees had deformed wings - Deformed Wing Disease is something that bees can get from varroa mites. This is what my bees have.

I was so mad. And I felt I'd let my girls down by not checking earlier (I should have started checking in late summer). And furious at the mites.

My bee mentor had me dust my hives with powdered sugar, an increasingly common method of dealing with mites in a non-pesticidal way. The sugar makes the bees groom themselves more assiduously and also causes the mites to not be able to stick to the bees with their horrid little sticky feet so they fall off (and through the screened bottom board, where they fall out of the hive. If you have a solid bottom board they can climb back up and on the bees again). The bees do *not* like the sugar dusting. They came boiling up out of the hive boxes all dusty white and shouting at me.

I read that certain essential oils - spearmint and lemongrass and thyme - act as biopesticides and have have been shown in lab tests to kill the mites. My kind of solution. Also there is a product called "Honey Bee Healthy" which uses both spearmint and lemongrass oil to both stimulate bees to eat (when it is in the sugar syrup) and to calm them instead of smoke when you spray it on them. The latter works - I saw it myself. I found a recipe on line to make it at home (cheaper than ordering it from a company and simple to do). It was so fragrant that the bees clustered at my kitchen window screens while it cooked.

So in the remaining warm days I am trying to dust my bees with powdered sugar a few more times before it gets too cold, spray them with spearmint and lemongrass oil, and feed them as much sugar syrup as they'll eat.

It was cold this week - mornings in the 40s. The bees are starting to cluster in the hive as they do in winter; and the few who were outside moved soooooo slowly.
