Is this bee dysentery?

[Gurus_username]

If it is, what should i do about it?

I'm a new beek, with one hive in Victoria.

No.
What is the device the spots/debri sit on?

Cheers.

I would guess that it's propolis, but it's difficult to tell.

It's a billie blu ventalated bottom board.

Thanks for the reply

Okay.
Out of interest (mine) would you be able to supply landscape pix of frames
#3+#4+#5+#6 for one side of each, please?
No rush. I'll mark this topic as "watch".
Thanks.

The girls cleaned up everything that was on the bottom board the other week. No worries there. Now my worry is that my queen spent a couple of weeks above my excluder, my honey super is getting near to full so she didn't have much room to lay, poor thing,  hopefully things will be close to back to normal at my next inspection

You should add another brood box and give her some more room to lay. Put it on top with a few frames from the bottom brood box and they'll build upward.

@Gurus_username.

Firstly do accept my gratefull recognition of the work you
went to in supplying photo stories - you help way more
than you could know.
Having noted and taken a keen interest in the VBB (type)
you are using I'll go on to say why the interest now I have
your hard evidence.
The single most significant problem with SBBs is the mesh,
bees cannot handle that extent of open realestate and whilst
some (races) do try to close it up some for most they simply
retreat from the near side of combs to mesh when localised box
temperatures drop below a point they can raise brood in.
Your location (Footscray) is important in that respect as aside
from some areas in alpine Aussie and Tassie, along with periods
of that miserable weather of KI and SouAussies peninsula, there
would exist not so many locations a SSB would make a whole
lot of difference to box temperature in holding brood rearing back.
What I was looking for was evidence that VBB is not affecting
the extents of brood rearing in the BC (broodchamber) and with
that an active broodnest front....24/7.
I have marked up two of the images to demonstrate the use of
 realestate with this VBB on board. Given the measurements
of the vents I would fully expect that in some conditions the bees
would close these up partially simply because they can, in contrast
to SBBs where it is 'better' for them to simply not use those areas.
One image is upside down - apologies.
Were you to force bees to place the stores above the BC I would fully
expect they would produce a broodnest close to the other attached
 example. Yet as it is with honeybands as shown they are doing very
well.
Now you have the queen below the excluder (QX) they will quickly
return brood to it's rightfull place. Given the close of summer coming
I would recommend you do no more than observe for now as being a
first year for this colony they are going to require *all* they have stored to
set themselves for next Spring after whatever Winter does arrive.
Of course they could get lucky with a local late flow, your call on that.
What is not clear in all that ramble..?.. please do ask clarification.

Cheers.

Bill

Interesting device.  I think of a SBB as a device for letting debris and mites out of the hive not a ventilation device.  It is hard to tell physical size of the slots from the photo but it looks like the bees could propolise it up if they wanted to.  Also without letting the debris fall through it might get plugged.

Yes Ace, a perspective generated from continually owning "dirty" BBs which is
a direct outcome of either low numbers than the box volume requires or bees
not inclined towards hygiene. One can be fixed, the other culled.

Regardless of how you view SBBs the fact there is a bloody great hole bees cannot
control is "ventilation".
Some apply a closure below the screen which in turn generates a rubbish/trash
 bin/can bees cannot access and so creates yet another problem for bees. Sure
regular removal to clean off has merits _provided_ it is done regularly like every
other day where the colony is active and not viewed from the stoop/patio (beer
in hand) with a "must pull those corflutes, shortly" approach to beekeeping.

Cheers.

For cleaning purposes I would say once a week is more then adequate unless you are monitoring mites.  Then it is every day.  This work you speak of is the difference between how a hobbyist thinks vs. a commercial operator.  The commercial operator doesn't fret over one or two hives where as a hobbyist does nothing but fret over one or two hives.

Rest assured any commercial operator in this Country would be fretting
over the boxes running SSB, which is likely why it would be rare to find a
savvy b'keep (any) using the design yet partly why my interest in this newer
style VBB is piqued. I say "newer" as VBB of another style was introduced
here in the late '60s as a miracle cure for hot stacks. Similar to SBB in
construction a solid round of failed colonies saw the concept dropped.
Back then WM was our only concern.
Some light reading for you.
