The Canadian Honey Council (CHC) is the national
organization of the Canadian beekeeping industry
and Hivelights is the industry’s magazine. Our
association is an “organization of organizations”.
One of the benefits of belonging to our member
organizations is that all members receive a copy of
Hivelights magazine. In order to receive Hivelights
you must be a current member of your provincial
association. International subscribers can receive our
high quality magazine for a fee of $50 Canadian per
year.
This was my first swarm. It happened in
Vancouver, in the Little
Mountain area. The bees left their hive
and went across the lane to the
bird house in my neighbour's yard. We
successfully rehived them.

Canadian Honey Council Report
Rod Scarlett, Executive Director, CHC
At the time of writing
this the honey pull is
just starting. The spring
brought some good news
and some troubling events.
While not yet having access
to the final statistics it
looks as though most of
Canada had very good
over-wintering statistics.
Many beekeepers reported losses of
less than 10% and many reported
strong healthy colonies. This
was tempered with a bee kill in
southern Ontario that resulted in
many beekeepers losing substantial
portions of their operations. At the
request of the Ontario Beekeepers
Association the CHC has struck a
committee to investigate what can be
done to prevent the same situation
from occurring. Coupled with the
PMRA announcement that it is
re-investigating neonicitoids, there
should be significant information
available shortly. There is no easy
answer to this nor is the question
very simple. What this event has
shown is that safety net programs
are ineffective, information sharing
needs to improve, and that beekeepers
must continue to work with farmers,
industry, government and through
their associations. Considerable time
and effort has been spent by those
involved in this case and their work
is certainly appreciated. The OBA,
PMRA, PA’s Beekeepers and Bayer
all need to be recognized in trying to
address the situation.
In late June I attended an information
tour in Guelph, sponsored by Bayer
Canada, where the neonecitoid seed
treatment was being further tested
as per Pest Management Review
Agency requests. The Tour had
representatives from the beekeeping
sector, PRMA, USDA, and industry
in attendance. While not addressing
the bee kill incident, it did indicate
Bayer’s commitment to beekeeping
and ensuring science is at the
forefront of decision making.
In late May, CFIA contacted
me and asked that the CHC
gather information from
the industry concerning the
elimination of regulations
on standardized container
sizing. I included the
information in the edition
of b-talk but also arranged for a
conference call with 12 of the largest
packers in Canada. I think it fair
to say that a majority of packers
were not aware of any prospective
changes to container standards and

were surprised when I contacted
them with the slide deck and the
proposals. Those packers that were
cognisant of upcoming changes were
not aware of any process to speed up
the 2014/15 planned implementation
date. It was apparent, that contrary
to the impression that was left with
me, there is little or no appetite to
quickly introduce changes to current
standardized container sizing. The
matter is far more complicated
than just an administrative change.
Packers need to prepare for a number
of expected events and subsequently
need time to adjust to changes in
molds, labels, cartons, designs, and
marketing campaigns. Budgets and
budget planning will be impacted. A
response to CFIA was be forwarded
on June 15, 2012.

With these numerous reports being received the Ontario
Beekeeper’s Association (OBA) executive contacted
various government agencies and chemical companies
to ensure their awareness and involvement. Professional
testing and research is being provided on the poisoning.
The OBA-Technology Transfer Program is working with
these agencies to ensure all pertinent data and samples are
available. Beekeepers are searching for answers.
Nitro-guanidine neonicotinoid is widely used in agriculture,
including soil applications, seed treatment, as well as foliar
and greenhouse uses. OBA recognizes that nitroguanidine
neonicotinoids are widely used by our agricultural
neighbours. As stated by OBA President, Mr. John Van
Alten, “we want a workable solution for all partners in
agriculture, but not at the expense of the pollinators. We
need to ensure that non target insects are not negatively
affected by the use of these chemicals. ”

Over the last six weeks, reports have been received
throughout Southwestern Ontario of honey bee poisoning.
Symptoms ranged from unusually high numbers of dead
or dying honeybees in front of hives to complete beeyards
being depopulated.

Given the high number of reports of acute poisoning, and
with lab results indicating the presence of Clothiandin,
Ontario Beekeepers are pleased with Health Canada’s
initiative to re-evaluate nitro-guanidine neonicotinoid
insecticides and associated products.

After devastating hive loss due to acute poisoning symptoms,
Ontario Beekeepers were relieved to hear of Health
Canada’s decision to re-evaluate neonicotinoid insecticides.
The Ontario Beekeepers’ Association, established in
1881, is one of the oldest established farm organizations
in Ontario. It is incorporated under the Agricultural and
Horticultural Organizations Act (1987). The OBA’s mission
is to ensure a thriving and sustainable beekeeping industry
in Ontario.

As this is being written

the lack of brood in the

Spring 2012 seemed to
start as a good one for
most Ontario beekeepers.
Early warm weather had
the bees in good shape and
building up fast. Much of
the province was reporting
a winter loss rate of 10
to 15 percent. With a
spring like that swarming
was a problem for many
to manage but after the
past several years it was a
welcomed change. Then a
new challenge appeared.
As the corn-planting season
began in the southwest
portion of the province and
progressed northeastward
with the warming

temperatures, beekeepers
were seeing catastrophic
affects on their bees.
What appeared to be acute
pesticide poisoning was
affecting a large number
of hives and bee yards. It
was observed by many
beekeepers within 24 hours
of a neighboring field being
planted with corn that bees
were rolling out of the
hives to form a twitching
dying carpet in front of the
entrance. It was observed
that the affects seemed to
be seen only next to fields
that were being seeded
with pneumatic seed drills
and “theories” of the air
pressure combined with the
pesticide treated talc on the
seed may be a factor.
Since that time meetings
have been held with
the PMRA, Bayer, and
OMAFRA to try and
determine the cause and
come up with options to
prevent further occurrences.
Some of the affected
beekeepers were invited to
a meeting with the Federal

Agriculture to share first

June is

some sunshine. June was a
very wet and cool month in
southern and central Alberta.
It was very challenging as it
seemed like we could only get
2 or 3 days of good work in
the bees done every week due
to weather. Overall, it seems
that the bees have built up
ok. We had very good pollen
flows here and we had a
pretty decent dandelion flow
as well.
As I am writing this, we are
in the process of moving
bees in for pollination. It
has been going ok. Southern
Alberta has been very wet
as well. Some fields are not
accessible as they had up to
3 inches of rain last week in
some thunder shower areas.

things move along and we

high winter losses again in

reports indicate that Alberta’s

While most beekeepers across

Millions of bees stolen
from Alberta honey
producer
A honey producer near
Grande Prairie, Alta.,
suspects another beekeeper
may be responsible for the
theft of millions of his bees.
"You would have to have
pretty good knowledge of
beekeeping," Bill Termeer said.
"You'd have to have the right
kind of equipment to go in
there and open up these hives."
More than 150 of his 3,000
hives were taken over the
past several weeks, a loss
of about three million bees.
Termeer estimates the
theft will cost him $60,000.
The loss is not covered by
insurance.
"It just sickens my stomach,"
he said.
The province's chief
beekeeper Medhat Nasr
says bee thefts are rare, with
only five in Alberta over the
past decade. However, that
number is expected to rise as
new diseases and parasites
kill bees.
"If somebody did not take
care of their bees . their
winter kill will go sky high,"
Nasr said. "So, either you buy
new bees or look for some
other sources."
RCMP are now investigating
the theft of Termeer's hives.

As we near the completion of our
research project, we are pleased to
report updates on those objectives
already met and the status of those
objectives nearing completion. One of
our initial objectives was to compare
methods of disinfecting N. ceranaecontaminated comb, evaluated over a
16-month period during 2009 and 2010.
An updated dataset on the efficacy of
these methods at suppressing N. ceranae
spore production and their impact on
colony productivity and survival is
presented. Also shown are initial results
from a study comparing the effect of
different sample sizes and sampling
locations on Nosema infection levels
within colonies. During the summer
of 2011, we continued our work testing
promising alternative compounds to
fumagillin, based on those previously
identified from our bioassays in 2010,
as well as testing novel compounds
synthesized specifically for this work.
We also undertook an additional
experiment examining the effect of fall
fumigillin treatments on overwintered
colonies in commercial apiaries.
Objectives in 2011:
1. To complete our evaluation of acetic
acid fumigation, heat treatment and
irradiation as methods of disinfecting
N. ceranae-contaminated comb, and
their subsequent impact on colony
productivity, and colony survival.
2. To compare the accuracy and
variability of different sampling methods
in determining N. ceranae infection levels
in colonies.
3. To further investigate the efficacy of
alternative compounds identified during
the summer 2010 for Nosema control, and
to test additional new synthetic compounds
in incubator-based cage trials.
4. To compare the efficacy of fall-applied
label dose treatments of fumagillin, in
large and small volumes of sugar syrup,
for suppressing N. ceranae infections.
1. Evaluation of methods of
disinfecting Nosema ceranaecontaminated comb.
Though first discovered as a parasite
of Apis cerana, N. ceranae is now
closely associated with Apis mellifera
throughout most beekeeping areas of the
world. As a newly-identified parasite
of A. mellifera, the mode of transmission
and epidemiology N. ceranae is not fully
understood. Based on our knowledge
of N. apis, however, it is known that the
re-use of contaminated comb is a likely
avenue for transmitting spores within
and among colonies. Therefore we
hypothesized that methods previously
used to disinfect N. apis1, 2 on comb
might also be effective at disinfecting
N. ceranae¬-contaminated comb and
equipment.
The experiment involved artificially
infecting frames of comb with N.
ceranae spores, disinfecting them
using acetic acid fumigation, heat or
irradiation then placing these frames
into brood chambers, and comparing the
subsequent infection after establishing
bees on the comb.
Methods:
One hundred and ninety-two full-depth
Langstroth frames containing fullydrawn honey comb were sprayed with
an aqueous suspension of N. ceranae
spores, prepared the previous day
from adult bees sampled from infected
colonies. Confirmation of N. ceranae was
performed by polymerase chain reaction
(PCR)3.
Each inoculated brood chamber
prepared for the experiment had four
of these frames placed in its centre,
surrounded by five additional noninoculated frames. Each inoculated
brood chamber contained an overall
dose 4.51 × 108 N. ceranae spores.
After the addition of inoculated comb,
each brood nest was assigned to one of
the following treatment groups, with
each treatment group consisting of
12 replicate colonies: (1) Acetic acid
fumigation, (2) heat-treatment, (3)
irradiation, (4) inoculated-untreated
(inoculated combs that were not
disinfected), and (5) uninoculateduntreated (combs neither receiving
inoculation, nor disinfection). Sixty
1-kg New Zealand packages were hived
on the experimental equipment. (For a
detailed description of treatments and
colony establishment please refer to our
previous report).
JMP version 74 was used for subsequent
statistical analyses in all experiments.
Data are expressed as means ± standard
error.
Results and Discussion:
Multivariate analysis of our 16-month
data set confirmed significant differences
in Nosema spore levels in colonies among
treatments (F = 27.34; df = 4, 33; P =
<.0001) and across sampling dates (F =
10.7548; df = 6, 28; P = 0.0035), however,
there was no significant interaction
between the date of sampling and
treatment applied (Wilkes’ Lambda: F
= 1.0282; df = 112, 26.418; P = 0.4893)
(Fig.1).
Thirteen days after colony establishment,
spore levels within inoculated-untreated
colonies rapidly proliferated to 10.9
million spores/bee, whereas the spore
levels in the other treatments remained
below one million spores per bee. By 21
May 2009, 19 days after establishing the
package colonies, inoculated-untreated
colonies had ten-fold more spores per
bee than the other treatment groups.
The increase, however, began to reverse
by 4 June 2009 and continued to decline
until 30 July 2009, when infections
among the inoculated-untreated colonies
appeared to rebound to 1.6 million
spores.

increases were observed not among the
inoculated-untreated colonies, as was
the case the previous spring, but among
the colonies on heat-treated comb where
infection levels exceeded 1 million
spores per bee by 15 May 2010. As was
the case in the spring of 2009, however,
all infection levels declined for the
remainder of the summer by late May.

species composition during the course
of the experiment we analyzed the bee
macerates, generated initially to count
spores, by PCR techniques. Results
indicate that while none of the package
bees were infected with N. ceranae
at the time of colony establishment,
approximately one third had low levels
of N. apis (Fig. 2). This finding confirms
that N. ceranae was transmitted to the
bees via the inoculated comb as it was not
present among the package bees. This
pattern, however, reversed after the bees
were established on comb, such that both
Nosema spp. were detected in virtually all
colonies.
N. ceranae appeared to follow a temporal
pattern in which the incidence of colonies
exhibiting an infection declined to about
one third by fall after peaking in the
spring. Infections were seen to rebound
again in April 2010, however colonies
on heat-treated comb had the highest
proportion of mixed infections compared
with other treatments (Fig. 2). When
infections declined to very low levels
toward mid-summer 2010, all irradiated
colonies maintained pure N. apis while
the other disinfection treatments
harboured some proportions of mixed
species infections. The inoculated,
untreated colonies during this time period
had single-species infections only.
Collectively, our results also tend to
suggest that N. ceranae has a seasonal
phenology similar to N. apis in northern
latitudes, whereby spore reductions tend
to occur by the mid-summer periods
after peaking in the spring. Our results
further suggest that under northern
temperate climates, N. apis is not readily
outcompeted and replaced N. ceranae in
colonies.
As reported in previously, the positive
effect of disinfecting comb also appeared
to influence the productivity of colonies,
presumably through reducing N. ceranae
infection. There were significantly

after being established on irradiated

cover had the lowest level of infection
compared with the honey frames (F =
8.30; df = 2; 26; P = 0.002). In examining
composite samples of 60 bees, these
trends were again evident (13.62; df = 2,
25; P = 0.0001). Composite samples of
90 bees showed that the brood nest had
the lowest infection level and the honey
frames the highest with the inner cover
being intermediate (F = 4.86; df = 2, 25;
P = 0.017).
It is clear that bees collected from honey
frames consistently had higher spore
levels than those collected from the
inner cover and the brood nest. For
beekeepers wanting to increase their
sensitivity of detection for N. ceranae
within a colony, sampling from these
peripheral frames is desirable. In
general, brood nest bees appear to
have lowest levels of infection or
may, at times, be similar to sampling
from the inner cover. These findings
support historical work performed
with N. apis in which older bees on
peripheral frames had higher infection
levels compared with the youngest
bees in the brood nest area, with bees
on the inner cover being of mixed age
cohorts making infection levels from
this location intermediate between the
other two sampling locations. Sampling
from the inner cover, as we have
predominantly done in our work, is
likely to yield better information on the
average level of infection across all age
cohorts of the colony.
We are processing remaining samples,
particularly those of the 30 individual
bees per colony, in order to make
more robust conclusions about the
appropriate size and precision with
which Nosema infection levels can be
determined within colonies and apiaries.
3. Screening Alternative Compounds
Against N. ceranae.
During the summer 2011, we further
evaluated the two promising compounds
identified from our laboratory bioassays
on caged bees conducted during
the summer 2010. These included
carbendazim, a fungicide, and JP-P145a, an aspiring analogue of fumagillin
synthesized by Ph.D. student Johan
van den Heever. Mr. van den Heever
provided us with four additional
functional analogues of fumagillin which
were coded as: JP-P1-59a, JP-P1-50a,
JP-P1-56a and JP-P1-58a. One of
the objectives behind testing fumagillin
analogues was to understand the mode
of action of fumagillin against Nosema.
This is important because fumagillin’s
mode of action against microsporidia is
not well understood and as such using
a fumagillin analogue will allow us to
determine what functional regions of
the molecule contribute to its biological
activity. The second objective was to
determine if specific analogues have the
same efficacy as fumagillin but with more
desirable properties in terms of ease of
manufacture, stability in sugar syrup or
reduction in residue production in honey.
Methods:
ad libitum that contained 0, 0.04, 0.4 or
4 mmol of each test compound, except
fumagillin which was administered at
0.04 mmol. Each concentration was
replicated across 6 different cages.
Treatment efficacy was assessed by
comparing the density of spores among
live and dead bees from each cage
after 16 days of feeding on treated
syrup. Compounds were considered
promising if: a) spore levels declined in
a concentration-response manner, similar
to that for a positive control (fumagillin),
b) were significantly reduced compared
to those fed untreated syrup or c)
toxicity to the bees was low.
Of the two promising compounds
selected during 2010 for further
evaluation, and those additional
compounds tested during the summer
2011, only JP-P1-45a (coded in 2010
as JP-P1-7a) showed a dose-response
relationship against N. ceranae infections,

ceranae infections to almost undetectable
levels at 0.04 mmol, similar reductions
were only observed for JP-P1-45a at
higher concentrations (0.4 and 4 mmol).
Based on the results of all cage bioassay
trials to date, fumagillin is by far the
most effective compound identified
against N. ceranae infections in honey
bees. In 2011, carbendazim did not
prove to have suppressive effects over
the concentrations tested. The efficacy
observed for JP-P1-45a, the aspirin
analogue of fumagillin, continues
to suggest that the side chain of the
parent molecule may not be very
important for enzymatic recognition
and biological activity. This structureactivity relationship warrants further
investigation as a means of producing an
alternative to fumagillin.
Beekeepers are advised not to purchase
commercial products which purport to
reduce Nosema infections in honey bees,
other than fumagillin, as our tests over
the last several years have not been able
to substantiate any such claims.
4. Fall Fumagillin Treatment and
Monitoring through Winter 2011 and
Spring 2012
Fumagillin is the only registered
treatment for Nosema spp. in honey
bees. While its use in managing N.
apis is well understood, it remains
unclear how best to apply fumagillin to
provide optimal control of N. ceranae.
For example, label recommendations
for applying fumagillin to control
N. apis in overwintered colonies may
not be optimal for N. ceranae, as the
latter has been suggested to be more
prevalent during summer months
in certain regions7. Furthermore,
recommendations for syrup-feeding
fumagillin to individual colonies are
becoming increasingly inapplicable
with the widespread adoption of barrel
feeding in some regions. In order to
test the importance of the timing of
treatments as well as the effectiveness of
alternative formulations, we established
several experiments examining either
spring of fall-applied treatments of
the drug. Reported here are the
results of our latest experiment, which
16
August 2012
commenced in the fall of 2011.
Methods:
Thirty-six naturally N. ceranae-infected
colonies were identified on 7 September
2011 in a commercial beekeeping
operation in Northern Alberta. These
colonies were randomly divided among
three treatment groups, each group
with 12 replicate colonies. The first two
treatment groups received fumagillin
applied to the colonies at a rate of 97.5
mg a.i. per application as either a ‘Drench’
or ‘Syrup’. The drench treatment was
applied in 250 ml sucrose syrup (1:1 v/v)
poured directly onto bees in the frame
spaces. The syrup treatment was applied
in 2 L sucrose syrup in a frame feeder.
Control treatment colonies received
2 L unmedicated sugar syrup. All
treatments were applied in two successive
applications, one week apart, on 12 and
19 September 2011. As a result, each
colony received a cumulative dose 195
mg a.i. fumagillin, the recommended fall
dose for treating N. apis.
Samples of 50 bees were collected
weekly, from 7 September 2011 to 22
October 2011 from the inner cover of
the colony. From October 2011- April
2012 these indoor-wintered colonies
were sampled monthly from the winter
cluster. From April 2012 until early
June 2012, samples will be collected
biweekly, from the inner cover. Data
collected at the time of writing this
report is presented.
At the time of establishment of the
experimental apiary (7 Sept 2011), the
average Nosema load was 3.22 ± 0.51
x 106 spores per bee and the infection
level did not differ among treatment
groups (F=0.05 df=2, 35; P=0.94, (Fig.
6). Multivariate analyses of spores levels
over time showed significant differences
among treatments (F=8.92, df=2, 23;
P=0.0014), over sampling dates (F=16.30;
df=10, 14; P= <0.0001), and a significant
interaction between time and treatment
(Wilks’ Lambda: F= 1.87; df= 20, 28;
P=0.062). Five days post-establishment,
on 12 Sept 2011, there was a natural
decline in the spore level observed in
all treatments (overall mean: 1.8 ± 0.40
x 106), with the colonies in the syrup
treatment having the lowest spore level
and colonies in the drench treatment
having the highest spore loads; untreated
colonies had intermediate infection levels.
However, one week after the second
application, irrespective of treatment,
spore loads started to increase with
continued increases observed throughout

Figure 6. Mean number of N. ceranae spores per bee among colonies after treatment in the fall with

sampling date, the untreated colonies
had the highest infection level (20 x 106
spores per bee), the drench treatment had
intermediate spore loads (8 x 106) and the
syrup treatment had the lowest levels of
Nosema spp. (4.8 x 106).
In general, based on the results of all
spring and fall application experiments
performed to date, fumagillin has been
shown to suppress infections of N. ceranae
in commercial beekeeping operations.
Label dose applications of the product in
the spring confer significant suppression
of Nosema spp. until the end of summer,
irrespective of formulation. Applications
of 195 - 200 mg a.i., of fumagillin in the
fall, whether in full volume syrup or
drench applications, appear to suppress
spore levels lower than untreated colonies
immediately after application. Few
treatment differences have been observed
over winter months and suppression of
infection levels has been observed during
the majority of weeks of the following
spring. Under both treatment paradigms,
however, monitoring of colonies during
the subsequent fall or spring season is
essential to make appropriate treatment
decisions as levels of spores, though
suppressed compared with untreated
colonies, still may exceed the nominal
economic threshold value of 1 x 106
spores per bee and can be variable among
colonies. Our experience also speaks
to the need to improve and standardize
bee sampling techniques to reduce
the potentially large variances among
samples.
General Project Conclusions:
1. Irradiation is the most effective
method of disinfecting comb
contaminated with N. ceranae spores and
promoting long-term colony survival.
2. In Northern Alberta, N. ceranae spore
levels appear to naturally decline during
mid-summer, exhibiting phenological
patterns historically seen for N. apis.
3. Applications of 100 mg a.i. fumagillin
during spring, irrespective of the
formulations evaluated, are effective
at suppressing active infections of N.
ceranae until fall.
4. Applications 195 - 200 mg a.i.
fumagillin in low or high volumes of syrup
during the fall are effective at suppressing
active infections of N. ceranae immediately
after treatment and continue to depress
spore levels below that of untreated
colonies during the following spring.
5. For both spring and fall applications
of fumagillin, monitoring of spore levels
is still essential during the subsequent
fall or spring periods to make
appropriate treatment decisions.

In 2011-12, Mr. Johan van den
Heever continued as a part-time Ph.D.
student in chemistry at the University
of Alberta. Mr. van den Heever has
been devising the LC-MS/MS residue
detection technique for fumagillin and
its degradation products in honey and
has synthesized novel compounds as
alternatives to fumagillin.
Future Activities
6. With collaborators at the Agri-Food
Laboratories of the Province of Alberta,
a new LC-MS/MS technique for the
detection of fumagillin and its primary
thermal and UV degradation products
has been developed.
7. An aspirin analogue of fumagillin
appears to be a promising synthetic
compound at suppressing N. ceranae
infections in caged bees.
Continued research in this area will
focus on the determination of incurred
fumagillin residues in colonies and
further bioassay work with novel
compounds to treat Nosema spp.

Poland Beekeepers Dump Thousands
of Dead Bees in Protest
Submitted by The Editor
On March 15, over 1,500 beekeepers
and anti-GMO protesters marched
through the streets of Warsaw,
depositing thousands of dead bees
on the steps of the Ministry of
Agriculture in protest of genetically
modified foods and their pesticides
which are together largely responsible
for the killing off of bees, butterflies,
moths and other beneficial pollinators
in great numbers.
Later that day the Minister of
Agriculture, Marek Sawicki,
announced plans to ban MON810,
which has already produced millions
of hectares of pesticide resistant
“superweeds” in the US.
The Polish Beekeepers Association
organized the protest, joining forces
with International Coalition to Protect
the Polish Countryside (ICPPC) and
the Coalition for a GMO Free Poland.
Targeting Monsanto’s MON810 GM
corn in particular, they also called
for a complete ban on all genetically
engineered crops as well as the
pesticides found to be most damaging
to the environment (and particularly
to bees).
In 2008, the Polish Parliament banned
GM feed, including both the planting
and importing of GM crops. “Despite
this progressive step,” reports Food
Travels, “the European Commission
has refused to accept regional bans
on GMOs, keeping Polish farmers,
producers, and activists on the offensive.”
Regardless, says the ICPPC, “None
of the nine European Union countries
that have already prohibited MON
810 did so by asking the permission of
the EU.”
There was a great variety of attire as
beekeepers dressed in their work bee
suits and masks and ran their hive
smoke guns as they marched, many
wore yellow jackets with the famous
Einstein quote, and many more
original signs, props, and costumes.
The ICPPC is asking Polish residents
to write Minister of Agriculture
Marek Sawicki, demanding that he
implement an immediate moratorium
on GM crops, without waiting for EU
approval.

In a honey bee hive, an
interesting find
F
David Ostermann, Business Development Specialist - Pollination Apiarist
Manitoba Agriculture, Food and Rural Initiatives, Winnipeg, Manitoba
For those interested, larvae of an as-of-yet unidentified insect
were found on some honey bees in a hive in Manitoba. See picture
attached
At this point it’s suspected they are beetle larvae, perhaps of the
family Meloidae, which includes blister beetles. Larvae are being
sent out for id. A cluster of the larvae was between the thorax and
abdomen (see picture) of some live bees in the brood area of the
hive. It‘s estimated less than 1% of the bees had these on them.
The honey bee colony was in 3 standard boxes but appeared to be
struggling from varroa which was seen on some bees. The larvae
were only found on live bees on frames. On the way home from
the site, a couple bees I collected with these larvae on them were
twitching and seemed otherwise paralysed. Other bees with the
larvae on them seemed ok.
