    Default Nosema symptoms

    I lost my two russian/carniolian hives this February. I believe it is because the winter clusters got too small to raise brood. One over the phone diagnosis was nosema c. and that could be why the cluster size declined. There was never a smattering of brown goop on the outsides of the hives.

    What symptoms should a novice beekeeper be looking for?

    Both packages installed in April 2010 had built up two brood boxes and drew out two supers. I thought that they were booming!

    Nosema symptoms are the same as poor ventilation, high humidity, poor weather, and poor diet. The only way to isolate which is correct is dissection and spore counts of the corpses.

    I've read (don't remember where) that Nosema M. leaves poop but that Nosema C. does not leave poop stains.

    Dwindling, queen supercedures, dead bees in pile on bottom board, refusal to eat syrup or excessive drowning in syrup. All symtoms I've heard, or felt myself from limited scientific info, were from Nosema C.

    Doesn't mean that something else might have some or all of the same symptoms. Best way to know for sure is to send samples in for testing.

    Why are you required to get shots to go overseas?
    Not so you won't get sick.
    It is so you won't bring the sickness back with you!

    This will draw flack but consider treating all new arrivals to your yards with one set of treatments for N.

    Send them in, it's free and takes about ten days. You can send comb or samples of poop. Then you will know and we want be guessing.

    I have already cleaned up the hive and do not have any left to send out. Amateur mistake unfortunately
    Hoping for better luck with new packages arriving next month.

    I may be wrong, but I think you mean Nosema A. and Nosema C. haven't heard of M.

    You're not wrong at all Honeydew...
    I don't know how that A got changed to the M, but there it is in plain sight.
    LOL thanks for catching that and for the correction.
