Congestion in the Brood Nest

Congestion. A topic I repeatedly misunderstand. And, in all likelihood I remain confused. Congestion, which leads to swarm behavior.

I used to think congestion was not enough room within the hive to comfortably house all of the bees. Kinda like when your cousin comes to town with his 6 kids and stays for a week. Apparently this is in error. Adding an empty box with foundation may help a little because the wax producing aged bees may go up and draw some wax but that’s not it, really. I mean your cousin’s kids are still holed up in your bathroom even if you make them sleep on the back porch. With my cousin’s kids it’s not congestion in the house, it’s congestion in my bathroom. With the bees it’s not congestion in the hive, it’s congestion in the brood nest.

So, I’ve read about opening up the brood nest with an empty frame. I tried this a few years ago (2015) only I couldn’t bear to place an empty frame in there so I placed a frame with foundation. Mistake again. Placing a frame of foundation only split the brood nest up causing more problems rather than helping.

So a couple years ago (2016) I thought maybe it’s time for me to switch to nine frames since I have drawn comb now. That has to be more “open” right? Turns out I got it wrong again. What this would do is reduce the number of frames for bees to hang out making them more likely to be crowded on each frame.

Okay, so what I understand now, I think, is (how can I really know anything when it comes to bees?) that it is nurse bee congestion in the brood area, not bee congestion. And it is not simply too many nurse bees. I mean it IS too many nurse bees, but more importantly it is unemployed nurse bees in the brood nest. The nurse bees are getting in each other’s way. There is an overabundance of out-of-work nurse bees for the amount of work available. It’s like ladies night and there are only 4 guys in the bar.

So, what does a colony do when it has too many nurse bees, which also happen to be coming into wax creating age? Swarm, that’s what.

So how do we reduce their unemployment and keep them in the hive? Give them work. 1) Add drawn comb in the brood area for the queen to lay in, producing more work space and more employment opportunities for nurse bees as well as spreading them out (reducing congestion). 2) Also add drawn comb above the brood nest for the bees to store nectar in thereby reducing the tendency to backfill the brood nest with nectar.

All this adding of drawn comb into critical areas promotes more work space, egg laying, and work opportunities also creates some disruption in the hive, something I consider beneficial during the period the bees are contemplating swarming. It may also allow for Queen pheromone to be more equally distributed amongst the workers which satisfies another swarm theory.

This worked for me last year so I’m going to confirm by trying it again this year. Good luck with your bees!

Pushing for Colony Reproduction

Not long ago, someone asked when we should start feeding the bees. The answer given was another question – What are your goals?

We want to building strong colonies but for what purpose? To catch the nectar flow? To make splits?, nucs?, or early pollination purposes? Each goal has a different start date.

Much of what we do with our bees involves looking forward. Last year I wrote a piece on when we should start the push towards building them up for purposes of capturing the nectar flow. I’ll bump that article to the top at a later date when it’s more relevant. Today, though, I’d like to think through another planning exercise for the beekeeper wanting to make strong splits from overwintered colonies.

I like bee math!

An experienced mentor and bee buddy of mine called me recently to ask if I wanted to order some early season queens. He caught me off guard just a bit because I really had not done my math homework for the coming splits season. Well, I’d better get hopping and decide if I’m going to order queens or make queenless splits.

And if I’m going to make spilts, when do I need to get busy?

Framing the issue:

We know from prior swarm seasons and winners of the “Golden Hive Tool Award” (given to the first captured swarm of each season) that swarming in the Midlands starts as soon as late, late February but typically early, early March and will remain strong for a month to six weeks into April then taper with an occasional spurts and sputters along the way.

We know that nature provides natural pollen and nectar for buildup in the Midlands around early to mid February (give or take). Some people see some earlier and this is climate and location dependent. So in nature we see feed for the bees a ~ month or so before swarming.

We know that the climate is still a bit dicey March 1st with occasional surprise freezes which could impact the survival of splits. I’m not sure I want to tempt Midlands weather.

March 1st looks to be an intersection between climate and colony readiness.

So, with natures help,some colonies are ready to swarm as early as ~ March 1. What constitutes being “ready?” Well, colony swarm preparations are a topic in itself but one hardwired componet is drone production. So we deduce that swarming colonies will have made drones ready to mate. I presume nature and the bees assume other colonies have done the same so as to provide some genetic diversity. But back to the point. If a colony is ready to swarm with ready drones when did they start those drones? The answer might help me as to when to start pushing buildup.

Let’s try to nail down a date to promote drone production by reviewing our bee math for drones: 3 days as an egg; 6 1/2 days as a larvae, and capped by day 10. 14 days as a pupa – 24 days. Right? Oh, but we must not forget that that drone is but a wee tot when born and needs to get to his “adolescence” to be ready for mating. That occurs after another 14 days give or take. Okay, I need to start making drones 38 days prior to making queenless splits. Right?…Wrong. Remember that if I make a split the bees will have to begin queen cells and we don’t need ready drones at the start of queen cells. We need them to coincide with the time it takes to make a queen and allow her to “harden” ready for her mating flight. Oh my, that probably negates some of my original calculations.

Nature tells me it will start making the splits for me (i.e. swarm) around March 1st. Let’s use that a  date that nature chooses as the earliest date swarms are likely to survive and use subtraction to come to the date I need to start building up my hives in order to maximize my success with queenless splits. March 1st minus 38 days leaves me at January 16th. I know this date as the birthday of Johann Dzierzon, father of parthenogenesis. (In animals, parthenogenesis means development of an embryo from an unfertilized egg cell. Ain’t that a coincidence?) But, as much as I would like to start pushing for drone production on Johann’s birthday, remember I need to deduct (or add back) the time for the colony to create a mating ready queen or approximately 20 to 24 days. My head is starting to hurt. Okay, January 16 plus 24 days = February 7th (or three days before Ormond Aebi’s birthday).

Isn’t it a curiosity that my efforts at calculations results in a bunch of needless time wasting when mother nature gave me the buildup date to begin with – the bloom of Red Maples! That is, when the maples bloom is the start date when nature itself provides the necessary ingredients to maximize successful colony reproduction on a date conducive to climate and impending nectar flow. You can’t fool mother nature. I’m exhausted but it serves me right. Beekeepers should probably reply to questions like this with bloom dates rather than calendar dates.

Will your bees be Olympians this year?

It takes preparation to get to the Olympics. Are your bees going to the Olympics this year?

Time is short. Will you be ready? Have you coached them up and prepared them for the adventure of the spring nectar flow? Are they building strength in population? Are they healthy? Is their mite count 1% or less? Is your equipment ready?

It takes approximately 6 weeks to prepare a bee population of sufficient size to fully capitalize on the nectar flow. The time to stimulate that increase is now. It is time to do everything you possibly can to get your bees healthy and increase their populations. The saying is, “build your bees before the flow, not on the flow.”

One either prepares before the nectar flow begins or one stays behind the entire spring. Nature does not wait for the procrastinator.

Winter Solstice for Bees

Bees in March

Bubbling over! These bees are overdue for some spring nectar!

Beginning of bloom

 

The Winter Solstice means something different to beekeepers. It’s typically associated with the beginning of winter for humans. But for the bees it’s the beginning of spring. Very slowly, as the days lengthen the queen will begin an increase in the number of eggs she lays. On a colony level, for the bees, the goal is to have a full staff of bees ready to reproduce on a colony level (i.e. swarm) at the beginning of plant nectar and pollen production (best chance of survival). That means preparations such as brood rearing begin during the first months of the new year resulting in hives bubbling over with bees by March. But it has other ramifications for the beekeeper wishing to discourage that workforce from leaving. The beekeeper seeks to 1) encourage brood rearing while 2) protecting the colony from starvation as the bees feed ever increasing numbers of larvae, while 3) discouraging swarm preparations in the same time period. It’s like walking a tightrope!
