Giving Eduction Method Another Chance...

I just can not give eduction method a rest, so, I am at it again using one of the stingless bee colonies at CVSU.  I am not doing it step-by-step. I immediately connected an eduction hive to the main hive. I am hoping the stingless bees are as intelligent as the cerana bees in finding their way out and then back again, though I think it would be much of a challenge for them considering their size.  They have a long way to walk to reach the exit.

I was able to take a small piece of brood from the main hive and put it in the eduction hive. This is suppose to speed up the process.  Now I think I know why, or at least I know one reason.  If new bees are to emerge from the piece of brood I put, then, those bees will consider the eduction hive their real home and they will start working on it.  I don't think they will be going to the main hive.  There should be at least a hundred bees in that piece of brood.

It is actually Day 2 of the experiment, and I still have to see a clear indication that the bees are able to make their way back to the main hive.  The photo was taken this morning and there was very little activity going on.  Hopefully, this coming friday, I will be able to observe the bees the whole day so I can track the movement of some pollen carriers.

I put plastic sheets on top of the hives so now I can watch the bees without them flying out.  Here are some photos I took.

this is the eduction hive...

and these are photos of the main hive...

To Feed or Not to Feed...

My dilemma right now is whether I should feed my bees or not.  About two weeks ago, I checked my hive and almost all frames were covered all over with bees... and a lot more bees are coming up because there are still lots of capped broods.  But I did not see any stored honey!  I did see a few open cells with nectar dotting here and there, which I believe were once brood cells. 

I am getting mixed info about honey flow period.  A beekeeper from Alfonso (about 8 km away from Amadeo), told me that their honey flow is over and he is not expecting anymore honey harvest this summer.  And he also told me that if I have lots of bees and no stored honey, my bees are in danger of starvation and the bees might abscond.  However one of my professor at CVSU (5 km away) told me that this summer is the period of honey flow.  Indeed, lots of trees are in bloom like mango, coconut, coffee, narra, and acacia. My galo tree is also in bloom right now and so is my guyabano tree.

Below is the map of Amadeo, Cavite.  The greenish circle represents 300-meter radius of foraging area while the reddish circle represents 900-meter radius.  Of course, Apis cerana has been recorded to forage up to 3 kilometers away from its hive.  Unless climate change will have considerable negative effect on the flowers, I don't think my bees are in danger of running out of natural food, especially since there are very few beekeepers around my area.  

For health reasons (mine and the bees), I really don't want to feed sugar-water.  I believe it is like giving bees junk foods.  The more I intervene with nature, the more harm I might cause.

But to be on the safe side, I actually put a liter of sugar-water outside the hive.  The last time I did that, the bees did not touch it.  Maybe the beekeeper at Lipa, Batangas is right.  He told me that if there are lots of natural forage in the area, the bees will not feed on the sugar-water even if it is inside the hive.   So, I guess, I will leave the decision to the bees.

Another issue I am facing is overcrowding.  During my last visit this week, again there were lots of bees outside near the entrance.  Maybe they did not like the box-hive super I added below.  I just hope they will not swarm again and reduce the strength of the colony.

Slice of (Bee) Life...

Finally, I was able to take photos of my Apis cerana bee frames!  The population looks good.  I was able to see some nectar in some of the cells which I believe were once brood cells.  But I did not see any pollen cells.  I also did not see any queen cells, which is a relief.  I am sure none of them will take off anytime soon.  Last time I visited them, I thought the bees were bearding at the entrance of one of the hive in which I installed the hive converter.  I plugged the original entrance so the bees will make their way down the box hive in order to get out.  Today, I did not see any "bearding" but just their regular "fanning" to keep the hive cool this summer.

The bees seem to hate having their pictures taken.  The moment I pointed the camera at them, they became aggressive and actually attacked the camera lens which was several inches away compared to my hand which is holding the frame.  The dark blurry patches on the foreground are bees attacking the camera lens.

Wow!!! This frame is almost completely covered with bees.

Looking down inside the hive.  Below the wooden grille is the expansion chamber which I hope, the bees will use in the coming days to come to build their new brood cells.  I am converting the frame hive to a Japanese type box hive.  It is similar to a Warre type hive but with fixed top bars instead of frames.

Capped brood cells (covered with yellow wax) occupy most of the lower half of the wax comb.  This is where new bees will come out.  The upper half is a bit new, which you can tell by its light color. The previous owner often harvest the top portion where the bees store their honey.  Fresh wax cells are used for raising broods first, then later filled with honey after the young bees emerged.  Already I can see some old brood cells (dark colored cells) filled with nectar.

Bees forming chains...

The queen is laying some drone (male) bees... you can tell by the cell cappings... drone cell cappings are dome shaped, bulging instead of flat like a regular worker cell cappings.  Drone cell cappings also have pin holes or at least a black dot at the center of the cappings.  Can you find the drone cells in this picture?

Some more close-up shots... I have yet to see a live Apis cerana queen... so, if you managed to find her in any of these photos, please let me know!

My sister's little 'La Presa' on our rooftop...

My sister took a vacation and left her little "La Presa" to me... it's a small 2 x 4 square-foot garden I built for her.  I think it is looking good now or at least it is getting better.  The tarragon looks happy. and the strawberries, well, they are fruiting... I think I will be having another strawberry tomorrow. The fruits are getting smaller though so maybe I should put more compost.  The runners seem to be shooting all over the tiny roof-top garden.  I hope it likes the micro-climate and spread like wildfire so we can have a small basket of delicious red jewels!
