One beekeeper in France measured the temperatures in his hive when the outside air temperature was 44°F. I have read that to keep the air flowing in the front of the hive, this is a practical way of doing it. Your support matters.

I have nice friends and go to a fantastic school.

The warmest place within a hive is in the center of the cluster. In my opinion, there is no need to close off the screened-bottom board in most parts of the country. Notify me of follow-up comments by email. This site uses Akismet to reduce spam.

Regardless of dictionaries, we have in entomology a rule for insect common names that can be followed. The third solution, which I have not tried, is to forego upper ventilation or quilts and simply place a thick sheet of nonporous insulation (e.g. That is because warm air rises. But the R-value of a pine board is not much, which means the difference in temperature between the inside air and the outside air is not great. I haven’t closed up the bottoms in years, and I know beekeepers in MA who don’t either. They exercise like mad whenever the mercury dips below about 50 degrees. The warmest place within a hive is in the center of the cluster. I just spent 20 minutes searching my own site for a photo I have of this, but of course, I can’t find it. The amount of heat lost (lumped thermal conductance) from conventional wooden hives, polystyrene hives, trees and other hives is discussed in this paper as well as the implications. When talking about open vents and ventilation there is little to no discussion of fluid dynamic issues related to the surface location of the air vents (or air entrances). Although my quilts have ventilation holes, the chips restrict the rate of airflow, conserving energy but allowing the dew point in the hive to rise. It seemed unnecessary to me, but might be fun to experiment with. It made the bees dramatically more aggressive in terms of defending their hive. The temperature is easily one of the most significant factors in when bees come out.

In fact, a whole new crop of workers will typically take over in the spring. The amount of energy/stores they have to consume in a wooden hive to keep warm and especially to evaporate water off honey stores (Hint – latent heat of vaporisation) is astounding and we should be surprised that we ever get a harvest in the first place! The other thing he said was noteworthy was the design of the hive, with rows of exposed honey combs. Bee Season. Thanks!

Beehives need to be kept at 95° F to be the right temperature to produce honey. I love bees and I do not want them to die because there wouldn't be any food for us to eat. What temp is too cold to break clusters for inspection of: brood health, is there a queen, etc…. 3. This is a good thing: you want some air flow through the hive to remove moisture, but you don’t want a wind tunnel.

Is it also recommended/suggested to insert the entrance reducing block to further restrict air flow? Andy, you can cut a small front opening in your inner covers, you can add an Imirie shim, or you can drill a hole in the upper corner of the top brood box. There are (at least) three ways to solve this problem. 2″-4″ thick styrofoam) above the inner cover.

It is amazing because the bees will provide enough ventilation to keep the temperature in the hive at 95° F. If the brood, the baby bees, get hotter than 95° they will die. Flowers that stink February (4) About Me. An old timer in my local group was talking about it. Also, because it is very dense, it has a high heat capacity. I enjoy reading this “physics” section. Honey bees can sense light, temperature, humidity, rainfall, wind and time of day. “While a European bee will chase an intruder up to 30 yards and then settle down, Africanized bees attack en mass and will give chase for 300 yards,” warns the Africanized bee section of the West Mountain Apiary website.

Rusty, this is great info. It also creates moving air currents inside the hive that serve to expel carbon dioxide and moisture.

1. I like my moisture quilts for the time being, but as I expand I might try the insulated-top-only approach. All rights reserved Honey Bee Suite © 2009-2020 by Rusty Burlew. Styrofoam, wood chips, or a layer of another material will slow the loss through the roof. The guy is kind of a kook honestly so, I wasn’t sure what to make of his idea. It’s warm enough here now for robbing, but most of the asters are gone. Beehive temperature is really critical to good honey and bee health no matter where the hive is located. Please email me at [email protected] so I can send you a link to the article once it’s done!

Nevertheless, the air inside the hive is slightly warmer than the ambient outside air. The cluster forms around and in the hive. As I mentioned in the beginning, natural systems do not waste energy.
