Abnormal Conditions Part II – Wax Moth, Monitoring Mites, and Antibiotics


[music] OK so today we actually have
another pest a couple things we are going to
show you relating to a couple different
abnormal type situations. So the first thing we
here to show you today is a colony that
has died within the last week so it is a
fairly recently dead colony, and what we have
inside, and we’ll just have a quick little
peek inside, is the very beginnings of a pest
called wax moth. And so you can see right
away this is an adult wax moth, so things have
obviously gotten to the point where they’ve gone
through their larval and their pupal stage and
now have emerged as adults, but the first
thing to notice and it’s kind of tough because
it’s very dark here, but this silky sort of
webbing that’s seen either on the surface of
the frame or sometimes we actually see these
little channels silk tunnels just underneath
the surface of the comb. Those are the signs and
symptoms of the wax moth larva chewing
their way through the comb, eating that and
starting to destroy it. So we see the adult and a
little bit more, we’ll see if we can see some more
signs and symptoms. So again we have
another adult here, we actually have a
little bit of extra. We actually see some
pupil casings, so they are a little white cocoon silk
cocoon that’s actually the wax moth in their
pupil stage and on the outside of that all that
black stuff is what’s called fraz and that’s all
the wax moth droppings. So something, obviously the
bees, would be cleaning up in their hives if they were
a good strong colony, so the bees do
take care of this. Wax moth is really only
a problem in dead colonies and comb that has
been stored I mean that is typically more in brood
chamber comb than honeycomb so
there’s those two. Last but not least the
last very clear sign you have wax moth
going on, here’s what we see we have a
couple again of these pupil casings, but these
silky tunnels going just underneath the
surface of the colony. When you see them in
your colonies you can’t miss them, you can’t
mistake them, they are very silky and very
clear as a tunnel just underneath the comb. So this is the very
beginnings of wax moth. Once they really
kind of take charge and if we were
to leave this colony out for a couple of extra
more weeks in this sort of heat the wax moth
would just completely take over this colony
and when they get to a certain point they do
destroy your comb, and if it is plastic it’s
not bad you just have to scrape that off
and start all over again, so you do kind of waste
a bit of the bees’ resource, but if it is if it gets to a
point where the wax moth have actually chewed
holes right through your comb,
if it’s a wood frame the best thing to do is
just burn that and start all over with some
new fresh frames. So wax moth there’s kind of
two different ways we can deal with wax moth. The first thing they like
warm dry sort of areas, so the sunlight isn’t so
much of a thing putting them out
they won’t really deter them too much,
but if you can somehow put them in a
room below 16 degrees centigrade, that seems
to deter the wax moth population from exploding
and you can get on top of the wax moth
that way, but what we’ve started to do is take
this colony this hive, put it above a queen
excluder on a good strong healthy hive for two days
and let the bees from that healthy colony
go up, clean that wax moth out and then
we can take that brood chamber away and
store it in a cool place, and that way the wax
moth has been cleaned up and we have a good
clean hive to get going at with what ever we
need to do after that. So that’s wax moth, and we don’t
actually have any products registered
for dealing with wax moth, so it’s more of a just
keeping on top of things and good maintenance
is the biggest thing when dealing
with wax moth. The second thing we have for
you today is how we monitor for varroa mites, so we use
what’s called a sticky paper method, so it’s
just an office folder that we’ve opened up and
then smeared with crisco just to make it
sticky so when the debris and these varroa
mites fall off they do get stuck and they don’t
blow away off these sheets. So we just line
that with crisco and put it underneath the
colony and then come back three days later
and take that out and that way it’s been in
there long enough that we can actually see
some mite fall, but not long enough that there’s
too too much debris on there and we are having
to sort through things. So we put it under
there for three days, take it out and it’s
just on a little tray here, so we can
slide that tray out and there we have
our sticky paper. So on a windy day you
have to be a little more careful, but on a day like
today all you have to do is just close that up and
make sure all the mites and debris stay in there
and then we can take it to our house or the
lab, count those mites get a mite count or
a mite fall per day. So this has been in for
three days we take the number of mites divide
by three and then it’s up to you to go and find
out in your area what the recommended treatment
levels are for mite fall per day, depending
on what time of year you are monitoring
for your mites. So that’s our sticky paper
method for monitoring varroa mites. The last thing we are
going to show you for the time being is just
a couple of the products that we have for
dealing with certain sorts of pests and
especially varroa mites, but as you can see
we have a variety of different varroa mite
controls and we also have a couple of different
antibiotic treatments here for your colonies. In your local jurisdiction,
if you live outside of Ontario, best thing
to do is just go online and find out what
sort of products and treatment levels and
all that sort of stuff is recommended in your
area, but in Ontario the best place to go is
to the OMAFRA website and we’ll have a link
in this video in the description below and
going to that OMAFRA website you can see
the products that we have available. The sort of pests they
do have these info sheets which are excellent
for reading up on what these pests are, who they
are, what they do and how to monitor
and treat these. So the OMAFRA website
is probably the best place to go in Ontario
for dealing with all these sorts of pests and
diseases, and that’s what I have for you
right now.

  1. Thank you to everyone for watching and supporting our videos! If you have any questions about our videos, please check out our list of FREQUENTLY ASKED QUESTIONS on our website, which can be found at http://www.uoguelph.ca/honeybee/videos-FAQs.shtml .

  2. Treating bees can make a strong colony weak, you disrupt the microbiological environment inside the hive.
    What about the varoamites that survive the treatment, will they not in the long run become resistent and a bigger problem, just like the multiresistent bacteria in hospitals?

  3. what is the bag of stuff and what is it used for I think it is Oxytet-25 but could not see the label very good thanks

  4. Say I have a super that I just harvested and I'm planning on storing it during the winter. I pack it inside a black garbage bag and seal it tight. Is there still a chance of waxmoth getting in there?

  5. Knowledge is paramount in the bee rearing arena, thanks!! You might want to reduce the amount of times you say "a" and "um", sorry, just a pet peeve of mine.

  6. Do you practice any treatment free methods? seems there are quite a lot of successful beeks keeping colonies thriving with varroa.

  7. In the light of new regulations on antibiotic use, and in the face of what seems ubiquitous foulbrood rates, would appreciate a video dedicated to the whole foulbrood issue, especially how to protect your colonies against mobile stocks of possibly infected bees.

  8. Hi I was told you can store combed frames with wax moth in the freezer for a couple of days and that sorts them out. Is that a satisfactory method?
