Neonicotinoid Pesticides Cause
Harm to Honey Bees
Mainz researchers discover new mechanism associated with the worldwide decline of bee populations
Johannes Gutenberg Universitaet Mainz
One possible cause of the alarming bee mortality we are witnessing is the use of the very active systemic insecticides called neonicotinoids. A previously unknown and harmful effect of neonicotinoids has been identified by researchers at the Mainz University Medical Center and Goethe University Frankfurt. They discovered that neonicotinoids in low and field-relevant concentrations reduce the concentration of acetylcholine in the royal jelly/larval food secreted by nurse bees. This signaling molecule is relevant for the development of the honey bee larvae. At higher doses, neonicotinoids also damage the so-called microchannels of the royal jelly gland in which acetylcholine is produced. The results of this research have been recently published in the eminent scientific journal PloS ONE.
“As early as 2013, the European Food Safety Authority published a report concluding that the neonicotinoid class of insecticides represented a risk to bees,” said Professor Ignatz Wessler of the Institute of Pathology at the University Medical Center of Johannes Gutenberg University Mainz (JGU). “The undesirable effect of neonicotinoids now discovered is a further indication that these insecticides represent a clear hazard to bee populations and this is a factor that needs to be taken into account in the forthcoming reassessment of the environmental risks of this substance class.” Working in collaboration with Professor Bernd Grünewald of the Bee Research Institute at Goethe University Frankfurt, Professor Ignatz Wessler and his team uncovered this previously unknown damaging effect of neonicotinoids that impairs the development of honey bee larvae.
Wessler and Grünewald were able to directly demonstrate that neonicotinoids reduce the acetylcholine content of the larval food produced by nurse bees. Acetylcholine is a signaling molecule produced in the microchannels of the royal jelly gland of nurse bees. Comparable to neonicotinoids, it stimulates the nicotinic acetylcholine receptors that are also present in this gland.
“In lab tests we artificially removed acetylcholine from the larval food and the result was that bee larvae fed with this died earlier than bee larvae that received food containing acetylcholine,” explained Wessler. In order to examine the effect of neonicotinoids on the acetylcholine content in the jelly in more detail, bee colonies were exposed to various concentrations of neonicotinoids in flight tunnels (clothianidin: 1, 10 and 100 ?g/kg glucose solution; thiacloprid 200 and 8800 ?g/kg). “This exposure led to a reduction in the acetylcholine content of the jelly. Thus we were able to demonstrate that the field-relevant dose of the neonicotinoid agent thiacloprid (200 ?g/kg) significantly reduces acetylcholine content by 50 percent. On exposure to higher doses, we were even able to verify that acetylcholine content can be reduced by 75 percent. Exposure of the bees with the higher doses results in serious damage to the microchannels and secretory cells of the jelly gland,” emphasized Professor Ignatz Wessler. “Our research results thus confirm that the neonicotinoids can jeopardize the normal development of honey bee larvae.”
The EU came to a similar conclusion back in December 2013 and imposed temporary restrictions on the use of three neonicotinoids, i.e., clothianidin, imidacloprid, and thiamethoxam. It had already been reported in several scientific publications that high but not lethal doses of various neonicotinoids could be associated with the falls in the populations of wild bees, bumblebees, and queen bees. Also reported were abnormalities in breeding activity and impaired flight orientation in the case of honeybees. However, at the time there were critics of these reports who pointed out that, among other things, the researchers had used high, non-field-relevant doses of neonicotinoids and had carried out their experiments under artificial laboratory conditions. Moreover, the proponents of the use of neonicotinoids cited other possible causes of bee mortality, for example, the proliferation of the varroa mite and other pathogens.
Great Practical Beekeeping
Information for New Beekeepers

of the Northeastern Kansas Beekeepers’ Association)
Tips for May
- Check for ticks, they love beekeepers
- Wear as much protective clothing as makes you comfortable when working your hives. Work hives with slow, smooth movements. Jerky movements agitate the bees.
- Use your smoker each time you check your bees.
- Organize your bee tools in a toolbox so that you can always find them.
- The best time to work bees is during the middle of the day when the field bees are collecting nectar.
- Work each hive from the side or the back, out of the bee flight path.
- Inspect hives by removing an outside frame first. Lift straight up to avoid damaging bees on the frame
- When supering your hives add more than one super at a time if you have drawn comb. If you have new foundation add only one super at a time and start with 10 frames. Put your second super on after the first one is almost filled.
- Use queen excluders to prevent brood in your honey supers and as a deterrent to wax moths.
- Double check medication dates – safety matters. Don’t misuse any chemicals in the hive. Follow all time guidelines. Absolutely never medicate hives with supers on. It is illegal.
- Keep the grass mowed in front of your hives – it makes it easier for the bees to land. Old carpet scraps, roof shingles or weed barriers can be used to keep grass under control.
- Keep supers on until the honey is capped, unripe honey will ferment.
- Do not feed sugar syrup during a honey flow since the bees will store the syrup in your supers rather than your honey.
- Don’t get excited on hot humid days if the bees are hanging outside the hive. They are trying to relieve the congestion in the hive to cool it off inside. Earlier in the year this is an indication of swarming, but as hotter summer temperatures return it is natural, so don’t worry.
- Keep up with your record-keeping so next year you’ll know which hives produced the best for you.
Swarm Call Questions
Here are some questions to ask if you get a call wanting you to come get a swarm:
- Have you called someone else?
- How big is it?
- How high is it?
- Do you have a ladder?
- What have you sprayed them with?
- How long has it been there?
- Is it on your property?
- What is your contact number?
- Do you have pets that might bother me?
Just before putting on your supers you’ll want to check your hives to make sure that you have a laying queen and that everything looks ok. You should have both hive bodies mostly filled with brood and some honey and pollen. Avoid opening up the hive to look at the brood area unless you suspect a management problem.
Weak colonies should be combined with stronger colonies or requeened.
How do you know if the honeyflow is “on”?
- Fresh white wax is on the edges of drawn comb or top bars.
- Wax foundation is quickly drawn out
- Bees are fanning at the entrance
- Bees are extremely active at the entrance – they are coming, and going like crazy
- You can smell it – the odor in the apiary is incredible – it smells sweet, like honey
- Bees are docile and easy to work
If you have supers with drawn comb put on more than one at a time, this encourages the bees to bring in more honey and gives them more room to let the honey dehumidify. However, if you put on too many at a time the bees will “chimney” or just go up the middle and fill out only the center combs. You can encourage them to fill out the whole super by taking the full center frames and exchanging them for the outside frames – move the outside frames in the inside frames out – voila!
Since bees are hoarders, the more space you give them, the more bees will go out to collect nectar.
If you are using supers with new foundation then just put on one at a time and keep 10 frames in the supers. When the super is almost full move your outside frames inside and add your next super.
Make sure to mark any comb honey supers or frames so you don’t extract them. Best to paint these supers a different color or paint a stripe on each side.
Move your full supers to the top and your newer supers lower (just above the queen excluder).
Keep supers on the hive until they are capped with beeswax (have a layer of beeswax covering the honey).
This group is primarily for those living in Watauga and the surrounding counties who are interested in beekeeping. However, anyone who is interested in bees is welcome! We are striving to be kinder, gentler beekeepers.
From our club president:
Our meetings have ended for this year. We will all take a break, read some bee books, and plan our strategy for next year. Our next meeting will be the first Tuesday in March. Check here for updated messages. Happy Winter!!
Check out the Holiday Honey recipes under the Recipes tab!!
We beekeepers do get together on a regular basis to enjoy speakers and demonstrations and to share our thoughts and concerns. Meetings are typically held the first Tuesday evening of each month at 6:00 P.M. Meetings are held in the downstairs conference room of the Watauga County Cooperative Extension Building located at 971 W King Street, Boone, NC 28607. It is advised to park in the back, accessible from Poplar Hill Drive. Click on Events (above) for more information.
This group is primarily for those interested in keeping bees that live in Watauga and the surrounding counties, although we welcome anyone who is interested in bees. We will regularly post announcements as to meetings and events of interest to beekeepers, including fairs where we are exhibiting. In addition, we aim to provide a place for discussion of up-to-date modern beekeeping practices and procedures using the art and skills learned in our day to day endeavors. We hope to share our joy in working with bees, as well as our knowledge, with everyone interested in bees or beekeeping.
Honey Bee Disease Alert
Kaira Wagoner, University of North Carolina at Greensboro Biology Department’s first doctoral student, has uncovered a chemical that could increase the odds of honey bee survival by helping them better combat the parasites within their hives.Wagoner has been working in Prof. Olav Rueppell’s lab under his mentorship since August 2011, when she began working on her Ph.D. in the newly established environmental health science program. She received bachelor’s degrees in biology and health science from Guilford College, and earned her master’s degree in biology from UNCG in 2011.
After studying the effects of malaria-carrying mosquitos in her master’s program, Wagoner said she wanted to study a “beneficial” insect for a change. She added that the “complex behaviors” of social insects such as honey bees added to their intrigue.
Wagoner’s research focuses on Varroa destructor, also called the Varroa mite.
The mite is “probably the single most problematic” issue for honey bees, she said. Not only is the mite a “physical burden to the honey bee,” it can also transmit viruses to the honey bee.
Varroa mites reproduce by infiltrating the special cells in a honey bee comb built for larvae. The mites lay their own young in the cell to feed off the baby honey bee. When that happens, the honey bee larvae give off a chemical signal that alerts the nurse honey bees to the presence of the mites and the disease that comes with it.
In response, the nurse bees uncap the wax covering from the cell to check for the mites, and if mites are present, they remove the larvae from the hive to prevent the spread of disease. That behavior is called “hygienic behavior,” Wagoner said.
Her research suggests that the chemical could be used as a tool to breed hygienic honey bee colonies that show increased hygienic behavior and are therefore more disease resistant hives.
Wagoner said she believes that if that specific chemical is sprayed over the top layer of all the honey bee cells in a hive, the nurse honey bees will uncap and check all the cells, increasing their chances of catching and emptying cells with the Varroa mites. Cells without mites will be recapped and the larvae left to develop normally.
“We think it will help reduce the parasite load of the colony,” Rueppell said.
And reducing the parasite load means reducing illness and death, leading to more honey bees to pollinate crops.
Urban Environments Boost Pathogen Pressure on Honey Bees
North Carolina State University
Researchers from North Carolina State University have found that urban environments increase pathogen abundance in honey bees (Apis mellifera) and reduce honey bee survival. The finding raises significant questions as urban areas continue to grow at the expense of rural environments, and urban beekeeping becomes more popular.
“We wanted to determine if the increased temperatures and impervious surface areas associated with urban environments have an effect on the number of pathogens bees are exposed to, and to the bees’ immune responses,” says Steve Frank, an associate professor of entomology at NC State and co-author of a paper on the work.
“We also wanted to look at both managed honey bee colonies and ‘wild’ ones, to see if that made a difference – and it did,” says David Tarpy, a professor of entomology at NC State and corresponding author on the paper.
Working with volunteers, the researchers identified 15 feral colonies, living in trees or buildings without human management, and 24 colonies managed by beekeepers in urban, suburban, and rural areas within an hour’s drive of Raleigh, N.C. The researchers collected worker bees from all of the colonies, and analyzed them to assess the bees’ immune responses and their overall “pathogen pressure.” Pathogen pressure accounts for both the types of pathogen species present and the abundance of those pathogens.
The research team found that colonies closer to urban areas and those managed by bee keepers had higher pathogen pressure.
“Overall, we found that the probability of worker [bee] survival in laboratory experiments declined three-fold in bees collected from urban environments, as compared to those collected in rural environments,” Frank says.
However, the researchers also found that immune response was not affected by urbanization.
“Since immune response is the same across environments, we think the higher pathogen pressure in urban areas is due to increased rates of transmission,” Tarpy says. “This might be because bee colonies have fewer feeding sites to choose from in urban areas, so they are interacting with more bees from other colonies. It may also be caused by higher temperatures in urban areas affecting pathogen viability or transmission somehow.”
“Feral bees expressed some immune genes at nearly twice the levels of managed bees following an immune challenge,” Frank says. The finding suggests that further study of feral bee colonies may give researchers insights that could improve honey bee management.
“Honey bees are important pollinators and play a significant role in our ecosystems and our economy,” Tarpy says. “This work is really only a starting point. Now that we know what’s happening, the next step is to begin work on understanding why it is happening and if the same negative effects of urbanization are hurting solitary, native bee species that are presumably more sensitive to their local environment.”
Ten beekeeping crimes you should not commit
What are beekeeping crimes? A beekeeping crime is a skipped step, a missed opportunity, or an unfortunate assumption about either honey bees, beekeeping, or the environment we live in. They are crimes because they often result in the death of bees, the spread of disease, or unhappy neighbors. I’ve limited my list to ten, but you certainly know of others.
The order of these beekeeping crimes is unimportant, except for the first one.
Skipping the basics: Nearly every beekeeper I know started by reading a book about beekeeping. It’s fine to read a book about beekeeping, but only after you’ve read about honey bees themselves—how they work, what they do, how they’re built—in other words, basic bee biology.
It’s hard to manage something if you don’t understand the something you are trying to manage. Beekeeping is the art of managing honey bees, so all the beekeeping books make a heck of a lot more sense after you know something about bees. Trust me on this.
My favorites include The Buzz about Bees: Biology of a Superorganism by Jürgen Tautz and Honey-Maker: How the Honey Bee Worker Does What She Does by Rosanna Mattingly. If you realize that beekeeping practices are designed around honey bee biology, you will realize how much sense it makes to start at the beginning.
Not feeding soon enough or long enough: New beekeepers do not realize how disadvantaged a package of bees really is. You dump them in an empty hive and expect them to perform, but they have no home set up, they have no comb for a nursery or for food stores, and they have no food. To build comb and collect what they need—and to raise new generations of offspring—requires a ton of energy. As a beekeeper, that’s where your job begins. Feed those bees.
Folks argue that they don’t want to feed because they want “natural bees.” But in fact, nothing about that bunch of bees is natural. Those bees are most probably unrelated to each other, they never met their queen, they are far from home, and the move wasn’t their idea—not the time, not the place, not the method. You’ve done everything possible to make it hard for them, so the least you can do is give them a meal.
Natural beekeeping is something you grow into with time and experience. Natural bees don’t come out of package that was just shipped halfway across the country on the back of a truck. With a brand new colony in a brand new hive, do not be surprised if you have to feed all summer.
Ignoring Varroa mites: If you ignore Varroa mites or pretend they don’t exist, you are offing your bees. In North America, Varroa remains the number one problem that honey bees face. It is easy to blame other things for colony loss: neonics, Nosema, CCD, and yellowjackets are common fall guys when, in fact, it is most often Varroa mites that destroy the colony.
Here again, people argue against treatments because they want “treatment-free” bees. I applaud those dedicated bee breeders who are working toward treatment-free bees. But what they are doing is hard, expensive, exacting, and time-consuming work based on sound scientific principles and lots of experience. Ordering bees from a large producers and letting them die every year from Varroasis is not treatment-free beekeeping. In fact, it’s not beekeeping at all—it’s the negligent and unconscionable act of a neophyte.
Furthermore, those who practice the “live-and-let-die” method are hurting those that are trying to breed true treatment-free stock. That is because a Varroa infested colony that collapses is a “mite bomb” or a ”mite factory” that releases scores of Varroa into the environment for other beekeepers to deal with. The mites are transmitted by robbers or absconding bees and can infect other colonies for miles around. Even the carefully-bred treatment-free bees can fail in the face of a massive influx of mites from a careless beekeeper.
If you want to segue into treatment-free beekeeping, you can. But you need knowledge, resources, and a plan. You can’t just install a package from California and watch it die.
Opening a hive without a plan: Each time you open a hive you are committing a home invasion; you are going in there and screwing things up. Granted, beekeepers need to manage, and to manage you need to know what’s going on. But excessive muddling through the hive is counterproductive. Temperature readings in hives skyrocket after beekeeper intrusion, and much energy is spent trying to get their lives back in order.
My rule of thumb is simple: have a plan. Know exactly why you are opening the hive and what you hope to learn. Once you have discovered what you need to know, get out.
The most frequent objection to this advice is, “But new beekeepers have to open the hive to learn. If they never open it, they never learn.” So? Why can’t learning be a plan?
If your new beekeeper plan is “to learn to distinguish worker brood from drone brood” then go for it. Find what you’re looking for, take photos if you want, but once you’ve accomplished your goal, get out. Is that so hard to understand?
Assuming where the queen won’t be: This is an extension of Murphy’s law. If you assume you know where the queen won’t be, you will be wrong. I can tell you from personal experience that I have assumed the queen wouldn’t be in burr comb before I scraped it away. Wrong. I assumed the queen wouldn’t be in the empty super I threw in the grass. Wrong. I assumed the queen wouldn’t be on the outside of the end frame. Wrong. I assumed the queen wouldn’t be on the inside of the telescoping cover. Wrong. And most impressively, I assumed the queen wouldn’t be strolling across my bee-suited stomach. Wrong.
Please, please do not ever assume you know where the queen won’t be.
Following advice that doesn’t come with a reason: If a friend or mentor tells you to do something and they can’t give you a reason, don’t do it. Why anyone would do something to a beehive without a reason is beyond comprehension. Now, maybe it turns out to be perfectly good advice, but if there is no reason behind it, how will you learn anything? How will you know why you are doing it or if you should ever do it again? Or when? “Why?” should always be your first question.
Remember, too, that not all mentors are created equal. Some are a wealth of knowledge, some not so much. If your mentor tells you he does it that way because his father did it that way, you need a new mentor.
Cutting all queen cells: Nothing perplexes me more than the idea that if you see a queen cell anywhere, anytime, any season, you should dispatch it with vigor and malice aforethought. Why?
Queen cells are not virulent, they don’t cause death and destruction, they are not dangerous, dirty, lethal, poisonous, pathogenic or vulgar. And where are all the right-to-lifers hiding during this discussion?
How many times have I heard a new beekeeper say he destroyed all the queen cells, but can’t understand why his colony failed to raise a new queen? Really? Or “I killed all the queen cells then realized the hive already swarmed.”
This goes back to ignoring the basics and following advice without a reason. There are times to cut queen cells and times to cherish them. The beekeeper’s job is to know the difference.
Failing to recognize a nectar dearth: If you fail to recognize a nectar dearth, bad things can happen. Your colony may starve. Your colony may be robbed by bees from your own apiary or one miles away. Your hive may be invaded by wasps. Your bees may decide to up and leave.
These outcomes can be avoided by good management. You can protect your surplus honey by removing it from the hive; you can protect your bees by reducing their entrances or closing extra entrances, you can feed your bees, you can trap and kill wasps. The list of options goes on and on, but if you fail to recognize the dearth in the first place, you can lose your honey, your colony, or both in a matter of days.
Harvesting honey too soon: Of all the beekeeping crimes, this is probably the most common and it comes from beekeeper impatience. You’ve gone your whole life without homegrown honey, but now you need it immediately.
Remember, depending on how you started your hive (full hive, nuc, package) you may or may not get a harvestable crop the first year. Don’t rush it. If you do things properly and learn as much as you can, you will soon be drowning in honey. If you take honey too soon, your bees may starve and you will be starting over again.
In the meantime, I advise people who absolutely cannot wait to taste their own honey to go ahead and carve a small chunk from one of the frames. You don’t need to harvest gallons in order to have a taste. If you cut a few square inches from a frame, you can have that long awaited treat without compromising the health of the colony. Besides, nothing compares to a spoonful of honey still warm from the heat of the hive. Taste it and wait.
Attempting too much too soon: Mastering the art of beekeeping is a process. Don’t try to go treatment free, raise queens, try out six kinds of hives, sell nucs, harvest pollen, extract honey, capture propolis, and expand to fifty colonies all in your first year. There will be time enough to do those things and more, but take it slowly. There is an incredible amount to learn and you will never know it all. If you learn how to do one thing well before you add another, all of it will come out better in the end.
