How do you know the bees seem happy for the lift? sorry had to ask
These bees could be carrying disease and should be left on the ground. Weak bees weaken the hive. Let the hive get healthy. The disease will just expand in the hive to the point of taking it down completely
You have not mentioned your mite counts. Monitor monitor monitor. It is the basis of knowing what is going on in your hive! If you have the live and let die mentality then monitoring is a mute point. However if your goal is to get honey to pay for the up keep of you hive, and to see your bees grow, you need to know what is going on in the hive.
Gone are the days of our father's and grandfather's beekeeping where we place a hive and get honey and worry of nothing else.
A simple knowledge of what varroa mites do is good for any beekeeper to understand the detriment to the hive. As well a simple understanding of the hierachy of a hive will then increase the knowlege of how the mites take down the hive peice by piece
Bees start out as cleaners, then nurse bees, securty, and then foragers. Basically, there might be other jobs but those are the basic ones. As a bee moves up to a new job, a healthy bee takes it's place. A continous cycle of movement in hive.
Varroa start with the brood box bees, attaching themselves puncturing the cuticle of the bee. This allows for the diseases to vector into the bee, weakening the bee and shortening it's life span. If the bee who becomes a forager dies too soon, there is nothing to take the place, so a secutity or nurse bee moves up to soon, this in itself will cause the bee to die earlier than scheduled....and so on. This change in cycle will cause a ripple effect in the hive. When the work force is reduced, less food comes in, less bees to clean, less eggs get laid
Now add in the damage the varroa does to the larva.
The Varroa now enter the cells just before capping, they rest in the royal jelly until the larva has consumed it all. Then the varroa feeds off the larva, puncturing holes in the bee. The varroa lays another varroa male, the male sheds some "skin" in the cell, both mites, use the cell as a bathroom. The male and female mate, producing more females. All varroa in the cell, feed of the bee, defacate in the cell, and shed their skins. Now you have a weak bee who emerges who is to clean the cells, and follow the path of all the rest of the bees.
Only, that bee will not make it to the end of it's natural life. It will be unable to forage for food, due to the weakened state.
Mites double in % every three weeks. So this problem is not in just one bee cell. At 4% you will see brood damage. At the spring time (say May) of year 1% mite infestation will lead to a loss in honey production and a loss in winter survival if the mites go unchecked.
So if you get the picture i just painted, it is easy to see how mites can so quickly take down a hive in a two fold manner. One is on the bees when they are in the hive working and one is on the brood while developing. AT the same time. These mites are aptly named the Varroa Destructor.
I forgot to mention the diseases they vector in. Once in the hive, really hard to get rid of and cleaned up.It is costly, and will set the hive back for quite a while.
You have just recieved mite damage on brood and bees 101....
