Pic: honey bee lice

[van from Arkansas]

Probably 12 lice on this queen in the pic

The louse prefer the queen bee and feeds via the mouth of the queen as the queen is fed by workers.  The larva are maggot and feed on honey and pollen.  The louse are commonly confused with Varroa which are about the same size.  Varroa have eight legs, Louie hav 6 legs with distinct head throax and abdomen.  Apparently, the louse don?t harm the bees except for comb damage.  Not so sure I agree, but what do I know?

Braula coeca numbers have greatly reduced, perhaps wiped out, in managed colonies that are treated for varroa.  I can't remember seeing any in the last 20 years.  When I did see them, the colonies appeared normal and would make a honey crop.

I hope that ain't one of your queens, Van.
I've never heard of this pest before.  I can see how high numbers of them could interfere with feeding and perhaps the overall health of the colony. 
If OA or other organic acids help keep them in check it's just one more item on the balance scale in favor of OA treatment.

Not my queen, Mr. Hops.  Top of the morning to you Sir,   Yep, the Varroa treatments hammered the louse.  Not an issue for most.  I just wanted beeks to be aware of yet another yet never mentioned possible issue.

For ten years I have been studying bees and that is the first picture that I have seen of them.
Thanks for posting.

The louse look so similar to Varroa.  There are tiny, same size as Varroa.  Varroa are kinda circular shaped whereas the louse are more elongated but again, so tiny, hard to tell.  However, the louse are not a problem in the US.  They are here, but don?t harm the bees to my knowledge, only the food stores.

If a human needs a constant treatment of antibiotics is the human considered healthy?  No treatment comes without side effects.

Ace you make a good point about antibiotics, except OA is not and antibiotic.

OA treatment ain't constant or prophylactic.  It's responsive to tested condition.  And yes, there are side effects.  That's why we follow treatment and dosage protocols. 
Ignoring the pests has its own set of side effects, too.

Using OA in the hive for a pest that can't be eradicated year after year is IMV constant and prophylactic.  IMV OA or any other chemical should be used outside the hive with the addition of a luer.  Draw the pest away from the hive and kill it.  If you can make such a luer the results will be better.  But nobodies tried.
