First you'd better change your name. Russian have learned english, I see.
Russian queen doesn't seem to be laying yet..no larvae and no caps.
There is something really wrong. Would you put in Russian hive one italian larva frame. If they are queenles, you will se queen cells.
Russian hive was terribly aggressive until yesterday.....don't know what changed...had been stung EVERY time I checked them until yesterday. I mean, I take the inner cover off with plenty of smoke through the hole and BAM...they're all over me.
No hive is worth that. Varroa is not so difficult to handle that you must stand that kind of offensive. Not nice at all.
Italian queen has slowed down in laying and there are 6 or 8 supercedure cells. We did have 4 days of cool weather and rain last week. I'm gonna leave them alone and hope the queen is okay and the workers destroy the supercedures. Anything to worry about??
When bees has started those queen cells, they are not going to destroy them.
Two possibilities: 1) colony will swarm 2) or it will change the queen.
If your colony is full of brood and food, there is not enough free space, it may also swarm..
You can give larvas and eggs to russian bees. They grow them upp, when they have no brood work to be done. So Italian queen can lay eggs more.
You can also give queen cell to Russian and you see, what happens.
*** Very interesting knowledge. We have not Russian queens in Finland but it seems, that I am not going to touch that one even with stick.
From my bee hives it is 50 km to Russian border. I got 23 years ago my first varroa hive. To keep varroa in order is not problem here.
