"Baby mites" on worker brood (???)
« on: October 08, 2020, 04:01:04 am »
This is from the weakest hive in the apiary. Five frames of brood, almost no nectar stores, good pollen stores. Brood pattern is solid but they have a lot of drobe comb in patches and obviously she's skipping those now. They have a "mann lake" feeder on top but this hive hasn't found it (and I'm askeered to put in a scent).

Anyway, look here at this brood. I see this sort of thing a lot and I don't know quite what to make of it. Referring to the three worker pupae in the center of the pic: I think they've been uncapped from outside and they're dead in the cell. Then when I dug one out you can see they have some tiny brown specks on them. What's that about? Some day I'll have a microscope setup maybe but surely yall have seen this. 

I think they look like baby mites, maybe what they call the "protonymph" stage. In which case it's an "Oh no! Oh yes!" situation -- oh no because that's a lot of mites, oh yes, because apparently the bees think so too and they're doing something about it.

Your observations welcome. ;)

Looks like mite overload to me.. A good dose of OAV might help tremendously. One weekly for 3 treatments.

Do you treat your bees?

Thanks Matt. There are those who do not treat but is seems that approach is like trying to paddle upriver in a equally forceful current. I have been here for 2 1/2 years and it seems the results reached in most cases of non treating gradually end up in this way. Some do not like the idea of. chemicals, you can always treat organically as pointed out by Iddee.  Organically is a big word. I personally see no disgrace in going this route. On the contrary. At least we have effective natural options. Thats my opinion anyway. Wishing you the best.


Organically

adverb
1.
from or in connection with living matter.
"organically enriched soil"
2.
without the use of chemical fertilizers, pesticides, or other artificial chemicals.

The male mite is 1/3rd the size of the female.

The very small brown specks on the pupa are probably debris from the bees uncapping the cell, or flakes from the cell walls.

If it were me....
I'd take a clear pic on hi-res with my phone, then zoom in on the speck and see what it is, or if it has legs.

I don't bother with magnifying lenses anymore.  The phone cam is so much better quality, and has flash if I need it.

I thought of that. But at Beefest 2019 we spotted some male mites and they were grey/translucent. Definitely not the brown of these.

Totally a possibility. I could have gotten a better pic even with my phone. I didn't double check the focus. I also could have sampled those other cells. Next time!

Five kids being homeschooled so a microscope is in our future anyway. ;) may as well get some extra mileage. I would like a digital one for purposes of capturing images to share.

if no treatment works thats great and more natural. however i consider bees to be livestock and should be cared for as such. I have used the shop towel saturated with oa and glycerine. this placed on the brood chamber will eventually be chewed up and removed from the hive . in the process the treatment is distributed throughout the hive for an extended time ,supposedly for as much a month. :beemaster:

Those specs don't look big enough for mites.  The lower stages of the Varroa mites are white and not purplish brown like adults.  For each foundress there is one male (the first egg that is laid) and then another female egg every 32-36 hours or so.  So at the end when they emerge there are eight or nine female mites.  But of these only one or two make it to maturity and get mated and only those are viable.
