Small hive beetle making friends with the bees

I was looking through my library of pictures from the bee hives when I found this picture of the small hive beetle cozying up to a bee drinking honey. Amazing! This is a cropped close-up of a much larger view of a frame of honey at the end of the season.

The SHB looks kind of cute in this picture, but I squash them on the inner cover when I see them and celebrate when I find their drowned bodies in the apple cider vinegar in the Hood trap in my hives.

IPM and the Metro Atlanta Beekeepers Meeting

Tonight the Metro Atlanta Beekeepers' meeting centered on IPM (Integrated Pest Management). Jennifer Berry from the University of Georgia's entomology program talked to us about studies she is involved in about the varroa mite.

Although she did discuss some chemicals, I am not planning to use chemicals in my hive, so I won't report about that part of her talk. She did talk about research showing that the screened bottom board is essential to effective IPM. At UGA the screened bottom board stays open on the hive all winter long. She discussed three non-chemical ways to manage the varroa mite (all in conjunction with the screened bottom board):

1. Using hygenic stock such as the Minnesota Hygienic bee or the bees raised in N Georgia by the Purvis Brothers Apiary

2. Killing drone brood. The drones are in the capped state longer than house bees and so the varroa mite likes to lay her eggs in drone cells because the mite has a greater chance to grow up. So you put drone foundation in a frame in the hive and when the cells are capped, remove the frame and put it in the freezer. This kills the drone larvae (and thus the mite can't grow). Put the dead drone frame back in the hive and the bees clean it out and start again.

3. Doing the powdered sugar shake (as I did this year). Take a flour sifter (now why didn't I think of that?) and sift the powdered sugar over the brood box. Put a sticky board under the SBB to catch the varroa which fall as the bees groom each other and the mites fall off. Then you can count the fallen mites to get an idea of how many mites are in your hive. If you do a powdered sugar shake every 10 days for a month, you should significantly lower the mite count.

I asked her about small cell bees and she said that the UGA lab is just beginning a study on small cell. One major beekeeper, Bill Owens, in Georgia has all of his hives regressed to small cell and she talked about his successes. With 800 hives, he has only lost 3 hives this year and not to varroa.

On the other hand, she mentioned that while Dee Lusby is going around talking a lot about small cell, she didn't feel convinced because she noted that Dee lives in Arizona and all the bees there are African honeybees - which have a shorter developmental cycle anyway and are varroa resistant. Jennifer's point was that the bees that Lusby has regressed to small cell would be small and varroa resistant because of their genetic heritage (African) and that the cell size didn't make a difference. She also talked about how long it takes to regress bees and how hard it is.

Jennifer is sampling honeycomb which Cindy Bee finds in her bee removal business. So far the "wild" comb is about 5 mm and doesn't support the theory that bees in the wild naturally build 4.9 mm comb. If you'll scroll down this link, you'll find a short write-up about both Cindy Bee and Jennifer Berry.

In spite of all of this, I am ordering small cell foundation this winter to begin regressing in the spring.

Unwelcome guest

After working the hives on Friday, I turned to gather my things to go back inside and discovered a visitor to my apple cider vinegar bottle. This wasp did not care if I smoked him/her (I tried to no avail) and generally looked menacing.

I left the vinegar jug outside overnight to allow the wasp to leave in his/her own good time.

By the way, most of the time now the hives look like the last picture. The bees are clustered in the center of the hive body to keep each other warm when the temperature is low and they are nowhere to be seen.

I miss them.

News about the shallow above the inner cover

Well, it's hard to explain what is going on. In the Destin hive, the middle hive body feels heavy and full of honey. They had moved some of the honey out of the super above the inner cover into the medium below. (It was 79 degrees in Atlanta on Friday so I felt safe to open the hives).

As you can see they stored pollen in one of the frames. In one frame it looked as if they were raising brood (above the inner cover???).

In Bermuda, they had moved very little honey into the lower hive bodies and the medium hive body on Bermuda felt lighter than the one on Destin. The last two pictures are from Bermuda where they appeared to have capped some of the honey but have not moved much if any.

I left both supers above the inner cover. I'll consult with the beekeepers at the Metro Beekeepers meeting on Tuesday and see what they advise. I believe anyone would say that it's a relative decision. If the bees appear to need the honey, then leave it there. If not, take the super off.

I plan to leave the supers above the inner cover a little longer. In Atlanta we have days with temps above 65 interspersed throughout the early winter, so I'll get to go back in the hives again, probably after Thanksgiving.

Hope everyone has a good Thanksgiving. I'll not be posting to the blog again until after Thanksgiving unless some exciting bee news comes my way while eating turkey!

Dead Small Hive Beetle - Drowned in Vinegar

It was 79 degrees in Atlanta today so I could go into my hives to see how things are with the bees. I emptied both small hive beetle traps and replaced the vinegar with fresh. Here are the drowning victims from the Destin hive.

I saw these dead guys but only two SHBs running around on the inner cover. In Bermuda there were only five SHBs in the vinegar trap and two of them were swimming around. I smashed them with my hive tool after dumping them out of the trap and refreshed the vinegar there too.

It was exciting to see such a lowered number of SHBs. Maybe they were hiding in the lower hive body, but I usually see 30 or so in each hive on the inner cover. Maybe they don't like vinegar and don't like the colder weather.

When I closed up the hives and turned around to gather up my stuff, there was this lovely wasp on my vinegar bottle. I smoked him/her, but the wasp stayed right on the top of the bottle. Needless to say, I left the bottle on the deck and will get it tomorrow when hopefully the visitor will not be there!
