Royal jelly conservation

[jeff33]

Random question but I have filled a test tube with some royal jelly which I planned to use on Thursday or Friday to prime my cells before grafting. It is out of 6 days old cells, should I assume that it will still be usable by then or freeze it?

Dry grafting works just fine so why bother? Also Royal jelly varies in content throughout the larval development so 6 day RJ not the same as that fed to 1 day old grafted larvae.

If you look closer couple of hours later, bees eate that old stuff away and start feeding from beginning.

However I use that jelly, because it is easy to put larva onto jelly. It is like a glue.

Do you collect it and keep it in the fridge ( not freezer at -18)??

Nowadays I rear queen in swarming hives. I use to change the larva in swarming cells.

I take jelly from some hive.

( I wonder from where that red face appeared?)

It keeps well in a deep freeze, I store it in small plastic Eppendorf tubes, when needed I put a tube in my shirt pocket to warm up a couple hours before doing grafts, have even used it after being in the freezer for two or three years.

It seemed to be a shame to waste it as it was readily available and a 2 minute job. I will try a bar with and 1 without to see if it makes a difference although as I have never grafted before this exercise may be pointless.
