The joy and the pain of beekeeping
The answer is mixed: one hive, the blue one, is doing splendidly. Lots of honey from last season, lots of brood, lots of workers. I had checked in three weeks ago, before leaving on a big trip, and came home intending to reverse all the hive boxes (swapping bottom with top boxes keeps a production chain going by putting the empty frames back on top for Queen Elizabeth to fill). This I did.
My only concern about Elizabeth was she has more than the usual number of drone cells. Not so many that I think workers are laying (i.e. no queen present), but more than the usual distribution. I seem to remember that last year, prior to swarming, there were a lot of drone cells. Maybe Eliz was feeling crowded and the wheels are now in motion. This time around I'd like to split her hive if it comes to it, capturing bees before they leave. Also I might need to because I fear I am losing my second hive...
The green hive, Kathryn's, I was worried about last fall. She had a heavy varroa mite infestation and I'd seen crippled wing disease. Her worker numbers were WAY down after the winter. Three weeks ago I had given her a frame of Elizabeth's brood, hoping to boost numbers.
However, when I opened her up yesterday I saw: very small amount of brood, a spotty brood pattern, holes in some of the brood caps, and dead rotting larvae inside cells. All of this sounds like Foulbrood, a perfectly horrible disease that not only kills off the hive, but requires the keeper to burn everything because the disease is spread by spores which contaminate the hive boxes and frames.
See what I mean about the pain of beekeeping? I've put a call out to my beekeeping mentors to confirm the diagnosis.
*Sigh*. Such a bummer.

Air circulation and feeding in winter
from http://basicbeekeeping.blogspot.com/
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.
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.
WHAT ABOUT WINTER FEEDING?
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.
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.
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.
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.
We always appreciate your business, whether it is for your woodenware hive needs, queens, packages, nucs, clothing or extraction equipment, we always appreciate your loyalty.

Corn Syrup linked to bee colony collapse
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.
Here is a link to the study published by the ACS.

Hungry bees
So here is the embarrassing truth: I forgot my password to get back into this blog. Duh! I had written it down somewhere, but well, couldn't remember where I'd put it. Reverse engineered my way back to it somehow and here we are.
So my bees are at risk of starvation - not both hives, just Elizabeth who swarmed first, back in the early summer. Since she took off before the main nectar flow and left her daughters no queen and a diminished workforce, they didn't build up enough honey storage to get through fall, let alone winter. My bee mentor advised me to feed them as much sugar water as they will take.
Kathryn, on the other hand, swarmed late in the season, so she left a super full of honey. Happy hive: apparently one should go into the winter with at least one full honey super. I am feeding both hives to get them through the fall and get stores enough for the cold.
Interesting the difference that the timing of swarming makes. Always something going on.
