Why some beekeepers prefer top entrance?
-
One keeper I know uses both top and bottom. The top in his, is basically a hole drilled in one of the supers just above the excluder. He does this so the field bees don't have to crawl through the excluder when bringing in their load. It seemed to have worked well for him.
In the summer I crack the top cover to allow for more ventilation. My bees use the oval in the inner cover as an upper enterance. I'm ok with it if they are ok with it. I am going to do the hole in a box idea this year on my two established hives.

zan,
Additional external hive entrances are generally bad because it encourages robbing from external hives. This can not only decrease your honey reserves, but it definitely will make the bees more aggressive over time, and therefore harder to work with.
You can have the ventilation without an additional entrance. Just make sure it's SCREENED ventilation. See the information at http://www.beecare.com/Hardware/Brood-box.htm for detail on how you can retrofit your existing boxes to provide this very critical, year-round ventilation.

I have used upper entrances 40 years. They are good.
At winter they are necessary. Without upper ventilation bees get nosema.
We had last summer hot (32 Celcius !) and I had every entrance open.

Towards autumn I close most of them.
Main reason is that bees need not walk so much inside hive and they get out and in easily. They like to use entrance in the middle of hive.
-
I have both , top and bottom entrances, the top entrance is mainly for ventilation, I proped up the top cover and cut a 3/8 high and 3 inches long notch out of the intercover's front, the notch is on bottom of the intercover. I also have screen bottom boards and never close them off, leave all open all year.
-
I have all screened bottoms with no bottom entrance and only a top entrance. I can open up the SBB to get air coming in. I went to all top entrances because of :
Mice,
Skunk,
Opposums,
Snow,
Grass
I don't think I'll ever go back to bottom entrances. I've lost too many hives to possums, skunks and mice and I don't like cutting the grass or clearning the entrances of snow.
-
Of course, each beekeeper will decide what works best for them. I take this position because of long experience with beekeeping and observing their behavior in an apiary with many hives.
Every non-migratory hive should ideally have an elevated hive stand. This solves the problem with raiders like skunks, possums, etc. It also helps making lifting hive boxes and general maintenance easier. When used with a screened bottom board, it automatically decreases varroa population. It avoids the constant weed-cutting maintenance. And it has many other uses. See http://www.beecare.com/Hardware/Elev-Hive-Stand.htm for more detail.
In summary, a hive with a good elevated hive stand, screened bottom board, and ventilated hive components, solves all these issues without unnecessarily introducing additional entrances and the potential problems they can present, especially with weaker hives.

Your hives must be shorter than mine. I had elevated (on top of 8" concrete blocks) hives and got very tired of lifting that top super off when it was full. I had to stand on a box just to reach it. Mine are all on treated four by four rails now.

A little suggesition to stand: The lenght of vertical support should be at the level of horisontal support. So weight of hive will be directly on vertical boards.
Here is construction of mine http://bees.freesuperhost.com/yabbfiles/Attachments/Kuva_051.jpg
You have nice selection of pictures and easy to look. :P
-
I go to Austin soon,
wmakjones, it seems to me your place is not so far from Austin?
Finsky,
Why your upper entrances are not in center?
Michael,
Do you have some kind of landing board on top entrance?
-
Finsky,
Why your upper entrances are not in center?
When I put my hand into handle of box, and if entrance is very near, bees will sting into hand.
But really I do not know why holes are where ever :P

The elevated hive stands I build have a 16" height from the ground to the bottom board. The weight is distributed properly, and the stand is reinforced. See http://www.beecare.com/Getting%20Started/Assembling%20Hdw/Elev%20Hive%20Stand/Assemble%20Hive%20Stand.htm for some detailed pictures. These stands have stood up to many years of very heavy weight (often 300+ lb) and have not shown any signs of weakening or instability.

If the ventilation hole is actually an ENTRANCE, you will have this problem. Guard bees protect an entrance. They do not protect a screened ventilation hole.

So it is.
And hole is real entrance. Often big hive use more middle entrances than than major bottom entrance.
Usually I keep honey box entrances pluged because boxes would be too cold.

Well, so it is good and tested! It seem to be impregnated wood.

Only the wood for the legs is treated chemically, to prevent rot when in contact with the ground. The primary frame structure of the stand can be a soft wood, such as pine, if painted properly. Ideally, you should use a high-quality, exterior acrylic latex. See http://www.beecare.com/Hardware/Instructions/Painting/UBB/PaintUBB%20-%20Paint.htm for an example. Also, it is critical that you use screws designed for outdoor use that will not corrode and rust, such as deck screws.

You ever have issues with dead bees collecting on the bottom board? I suppose if the hive is nice and healthy it is not an issue, but if the hive is not as strong as it should be, do the bodies and other debris ever get out of hand?
-

Taw is right? Why bees dont defence their nest?
Is Michael the only beekeeper on globe who does not use bottom entrance
:?

With a bottom entrance the dead bees often block the exit in the winter. They accumulate to some degree with a bottom entrance or not. But the bees haul out the dead with a top entrance about the same. I usually dump the bees off of it in the spring and fall if there are any. Sometimes tehre are. In the fall they are usually drones. In the spring they are usually workers. But it's the same with a bottom entrance. Usually between spring and fall the bees keep it clean.
>Taw is right? Why bees dont defence their nest?
They do fine agains mice until winter sets in. The skunks are another matter altogether. it's defence that gets them eaten. They scratch on the hive until a bee flies out, catch it, roll it on the ground and eat it.
>Is Michael the only beekeeper on globe who does not use bottom entrance
Not at all. I've had corespondence from many beekeepers who have only a top entrance. Lloyd Spears's new top Sundance II trap requires only a top entrance.
BTW you can't use a queen excluder and only a top entrance. The drones have to have some kind of escape from the brood nest.
-
And what about landing board?
-
I don't use landing boards on the bottom entrance. Don't see the need for them.
-
And what about landing board?
I didn't use a landing board at all last season, but plan to this season and all that follow.
-
I like landing boards. On cold weather it is very good.
When bees bring heavy loads numerous bees drop onto board.
And it is fun to look how they walk to hive and what pollen they have in their legs.
Bees prefer round middle entrance. Often there are "rush hours" near openings.
-
>And what about landing board?
I don't use them. I don't see any use for them.

Thank you all. All your opinions are very interesting to me.
For few days i go to Austin TX. Do you have any suggestion what to see or buy there?
-
I don't use them. I don't see any use for them.
Yuo use lower entrance either. Do you mimic nature way ?
I look your homesides and you have landingboards there. :P
I see a lot of use to landingboard. It is just nice for many reasons. At spring when it is cold I put larger landingboard. When bees come home they should get in quickly. On rape field when bees come with heavy load they drop to grass. There are hunders of bees resting in front of hive when they tried to fly into hive. Last summer I had good pastures and bees need to fly only few hundreds meters to home. They flyed direct into hive.
Lower entrance is very good because it keeps hive warm. Warm air goes upp. In our climate warm is very important. We have just few days over 25C during summer.
But in Finland many are such opinion that landingboadr is vain. As you see, it is same what you use.
