READ: Brood diseases and lagging bees

by HoneyLover Susan Rudnicki

Spring is the time of year when bees go into high gear to get ready to do their instinctive reproductive act of procreation—swarming. A colony grows to fill its space, replacement queens are drawn and nurtured, and the final event is a leaving from the mother hive of about 50% of the workers and the old queen. These bees will attempt to found a new colony somewhere else and begin the cycle again. During this build up in Spring we urban beekeepers must watch carefully for the signs of swarm preparation and guide it so that a swarm is not the outcome—in the city such swarms are not appreciated by the general public living in close proximity to us.

I have now been keeping bees almost four years and am getting a better feel for the rhythm of the growth cycle in a colony. We have mild winters in Los Angeles, so the Spring brooding up period often begins in January. This means we will begin seeing drones and drone brood, new brood comb being drawn, and a general increase in the number of bees and activity of the queen.

However, early this year, two of my hives at the house were not showing these changes and I really began to notice by February. It seemed they were just staying in a holding pattern—no new comb was being drawn and, at first, this was the most noticeable issue. By the beginning of March, I was seeing sac brood, perforated cappings (small holes in the brood caps), lots of uncapped pupae in the purple eye stage, dried up “mummies” of brood in cells, and some cells of open brood with watery goop that may have been European Foul Brood.  There were also some adult bees with DWV, or deformed wing virus. The wings of the bee are twisted little stumps or thread-like and useless. The colonies had plenty of stored honey and many frames of bee bread. Together, these conditions and the different maladies of the larvae and pupae are sometimes lumped under the name “Bee Parasitic Mite Syndrome”  which describes diseases vectored by the activities of the varroa mite.

Here is a website entry detailing what I was seeing—

Information compiled by Beekeeper Lonnie E. Campbell of The Loudoun Beekeepers Association.

Bee Parasitic Mite Syndrome was first named by The Beltsville Bee Lab to explain why colonies infested with both varroa mites and tracheal mites were not thriving. BPMS was first reported by European beekeepers whose colonies were already stressed by varroa mites. Colonies that are apparently very healthy and productive suddenly experience a sudden decrease in adult population often resulting in the total loss of the colony. Plenty of food stores are often present, but very spotty and unhealthy brood are observed.

I began searching my readings and books to find out what I might do to help these two formerly thriving hives (one hive is 5 mediums, the other 2 deeps and 3 mediums). I wanted to support them before their population dropped too much that they would be weakened beyond recovery. I saw on inspection March 22 that very little open brood was present and no eggs. One queen was seen (in the biggest colony) but in the other I didn’t find the queen.

Michael Bush’s book offered the best information for this situation that I could find. A brood break, or a cessation of egg laying by the queen, is one of the best responses for breaking the cycle of the pests and diseases that may afflict a hive. By denying the pathogens a food source the disease cycle is automatically broken. One way of doing this is to find and kill the queen and then introduce a new queen. Another way is to dispatch the queen and let them raise another one. By the time the new queen is laying, the brood break will have cleansed the disease cycle.

But the method I thought I would settle on was the use of a push in cage. This is a small confinement cage made out of eighth inch hardware cloth that holds the queen on the face of a frame for a period of time to prevent her laying eggs in the normal pattern. It is just a shallow 3 sided box of wire, 5 X 10 inches, pushed into the face of the wax comb. You try to place it in a zone with some honey cells, some emerging brood, and some open cells—all of these to serve the needs of the confined queen.

On March 28, after preparing two cages and getting my mind clear about what I was going to do, I opened up the first hive to start my search for the queen. I had at hand a  good tool for safely catching a queen— a “hair clip” catcher.

However, I soon saw that something better than my plan had already occurred. The frames that had lacked any eggs or open brood were now completely filled with eggs! The queens had stopped laying eggs by their own accord and interrupted the brood cycle of the diseases and varroa that had been afflicting them. I was very excited that the queens and their workers seemed to have a inborn strategy to get over their problems. My notes to Michael Bush to report this were confirmed in his answer here:

         Yes, the bees often do a brood break to resolve the issues.  Sometimes it’s done by dispatching the old queen and sometimes she just shuts down. EFB usually clears up on it’s own when whatever stress was the cause is relieved.  Usually by a flow in a dearth.

And this one:

It doesn’t always work out well, but then interfering doesn’t always work out well either.

“Our attentions may be useful to them but are oftener noxious to them; thus far goes our interference.” –Francis Huber (in a letter to Elisa)

“…without the foresight, or rather the astonishing presence of mind of the bees, who always do at the proper time what needs to be done…” –Francis Huber (in a letter to Elisa)

So, there we have it. Another beek lesson learned!

READ: Urban beekeeping becomes therapy for at-risk communities

By North By Northwest, CBC News

Julia and Sarah Common started their urban beekeeping non-profit organization in 2012

Bees play an important role in the ecosystem, as they pollinate plants and produce honey, but it turns out they can also play a therapeutic role for humans.

Since 2012, Julia Common and her daughter Sarah have been engaging at-risk communities in urban beekeeping through their non-profit organization, Hives for Humanity.

Mother and daughter started by placing a colony of bees at a community garden on Vancouver’s Downtown Eastside.

“The community really quickly took ownership of that hive and responsibility for the protection and care of this living, breathing colony of working insects that are just this inspiration to everyone who sees them,” Sarah told North By Northwest‘s Sheryl MacKay.

The Commons say beekeeping is therapeutic because it brings people together and the responsibility gives them a sense of self worth and community pride.

“At the beginning, we thought it was the beekeeping, but then from beekeeping, other things come,” said Julia.

“The bees have wax, someone needs to [process] the wax. Other people come forward who want to help with equipment maintenance.”

Hives for Humanity now has almost a hundred hives placed in community gardens, the rooftops of single room occupancy hotels and people’s backyards.

“No matter where you are, people take great pride in taking care of the bees, keeping them safe,” said Julia.

“Everyone from kindergarten right up to somebody who is 92 realizes bees are threatened and they just feel wonderful that they’re playing their [part].”

READ: Bees prefer the buzz of a town

Bees prefer the buzz of a town: Urban sites found to have more species than rural areas

By Fiona Macrae via dailymail.co.uk

  • Agriculture and mass crops blamed for decline of bee numbers 
  • Towns and cities have wider variety of plants and flowers in autumn
  • Pesticides, climate change and disease causing bee numbers to fall 

We think of them as thriving in wildflower meadows and rolling fields. But new research suggests Britain’s bees are happier near towns and cities.

A study of wildlife sites across four English counties has found that most are home to fewer species of bee today than they were in the past.

It found that the expansion of farmland has actually been more damaging to Britain’s bee population than the concreting over of the countryside for housing.

Reading University researcher Deepa Senapathi believes intensive agriculture is to blame.

While the gardens, parks and churchyards of towns and cities provide bees with a variety of plants to forage on and an extended flowering season, popular crops such as oilseed rape only bloom for a few weeks.

She said: ‘While concreting over the countryside may appear to be bad news for nature, we’ve found that progressive urbanisation may be much less damaging than intensive agriculture.

‘Urban areas may benefit bees more than farmland by providing a wide variety of flowering plants, providing a cosmopolitan menu for insects from spring through to autumn.

‘Over the past century rural landscapes in Britain have become increasingly dominated by large expanses of monoculture – the growing of a single type of plant, which has helped boost crop production.

‘But without a mixture of habitat and food sources, rural areas can sometimes be little better than green deserts for biodiversity.

Scientists around the country are trying to work out why populations of bees and other insects are plummeting.

Pesticides, climate change and disease may, like intensive farming, be playing a role.

READ: Scientists discover what’s killing the bees and it’s worse than you thought

Outlawing a type of insecticides is not a panacea. (AP Photo/Ben Margot)

As we’ve written before, the mysterious mass die-off of honey bees that pollinate $30 billion worth of crops in the US has so decimated America’s apis mellifera population that one bad winter could leave fields fallow. Now, a new study has pinpointed some of the probable causes of bee deaths and the rather scary results show that averting beemageddon will be much more difficult than previously thought.

Scientists had struggled to find the trigger for so-called Colony Collapse Disorder (CCD) that has wiped out an estimated 10 million beehives, worth $2 billion, over the past six years. Suspects have included pesticides, disease-bearing parasites and poor nutrition. But in a first-of-its-kind study published today in the journal PLOS ONE, scientists at the University of Maryland and the US Department of Agriculture have identified a witch’s brew of pesticides and fungicides contaminating pollen that bees collect to feed their hives. The findings break new ground on why large numbers of bees are dying though they do not identify the specific cause of CCD, where an entire beehive dies at once.

When researchers collected pollen from hives on the east coast pollinating cranberry, watermelon and other crops and fed it to healthy bees, those bees showed a significant decline in their ability to resist infection by a parasite called Nosema ceranae. The parasite has been implicated in Colony Collapse Disorder though scientists took pains to point out that their findings do not directly link the pesticides to CCD. The pollen was contaminated on average with nine different pesticides and fungicides though scientists discovered 21 agricultural chemicals in one sample. Scientists identified eight ag chemicals associated with increased risk of infection by the parasite.

Most disturbing, bees that ate pollen contaminated with fungicides were three times as likely to be infected by the parasite. Widely used, fungicides had been thought to be harmless for bees as they’re designed to kill fungus, not insects, on crops like apples.

“There’s growing evidence that fungicides may be affecting the bees on their own and I think what it highlights is a need to reassess how we label these agricultural chemicals,” Dennis vanEngelsdorp, the study’s lead author, told Quartz.

Labels on pesticides warn farmers not to spray when pollinating bees are in the vicinity but such precautions have not applied to fungicides.

Bee populations are so low in the US that it now takes 60% of the country’s surviving colonies just to pollinate one California crop, almonds. And that’s not just a west coast problem—California supplies 80% of the world’s almonds, a market worth $4 billion.

In recent years, a class of chemicals called neonicotinoids has been linked to bee deaths and in April regulators banned the use of the pesticide for two years in Europe where bee populations have also plummeted. But vanEngelsdorp, an assistant research scientist at the University of Maryland, says the new study shows that the interaction of multiple pesticides is affecting bee health.

“The pesticide issue in itself is much more complex than we have led to be believe,” he says. “It’s a lot more complicated than just one product, which means of course the solution does not lie in just banning one class of product.”

The study found another complication in efforts to save the bees: US honey bees, which are descendants of European bees, do not bring home pollen from native North American crops but collect bee chow from nearby weeds and wildflowers. That pollen, however, was also contaminated with pesticides even though those plants were not the target of spraying.

“It’s not clear whether the pesticides are drifting over to those plants but we need take a new look at agricultural spraying practices,” says vanEngelsdorp.

Those Insecticides We’re Told Aren’t Killing Bees Are Also Hurting Birds

by Steve Williams

Despite many politicians being in complete denial about the mounting evidence of a connection between certain insecticides and the collapse of bee populations, new research shows that those same insecticides are probably indirectly leading to bird die-offs, too.

A new study published this month in Nature looks at data from the Netherlands which the researchers say shows a sharp decline in certain bird populations in areas where insecticides known as neonicotinoids were used the most.

Neonicotinoids are among the new wave of insecticides that have been developed in the past 50 years. They were supposed to be revolutionary for the farming industry and were billed as less damaging for the environment and wildlife. However, study after study has linked them to a decline in pollinators and even to bee Colony Collapse Disorder, while a 2013 examination of peer reviewed literature called for tighter restrictions on neonicotinoid use as, used in the concentrations and amounts that we see on farms today, the scientists concluded there is enough evidence to suggest that these insecticides are harming bees and other insects who aren’t supposed to be targeted.

Concerns have also been raised about the wider impact on wildlife beyond our pollinators. While neonicotinoids are billed as not being as toxic to mammals, and in particular birds of prey, scientific literature has suggested an unintended impact: by killing insects that the mammals eat, they may be driving down certain sensitive populations, and that’s precisely what the study from the Netherlands found.

Interestingly the researchers from Radboud University in the Netherlands started their research not by exploring the impact of neonicotinoids, but by looking at two different data sets, one of bird counts, and the other of surface water measurements of the most common neonicotinoid, and through this the scientists were able to track the decline in bird numbers during the period of 2003 to 2010 while leaving the door open for other possible causes of bird population decline.

They found that there may be several factors contributing to the fall in numbers, such as an intensification of farming which often means uprooting bird habitats, like digging up hedges or dismantling barns.

Still, the researchers found that the presence of imidacloprid, one of the leading neonicotinoids, is incontrovertibly impacting birds and may be the main cause of bird decline in the region. They found that if ground water had just 20 nanograms of neonicotinoid per liter, there was a 30 percent fall in bird numbers during the study period–and what’s more, some areas had pollution levels that was 50 times higher than that figure.

In total, the researchers found that 14 out of 15 common insect-eating bird species, like barn swallows, tree sparrows and starlings, had suffered sometimes dramatic population declines.

Research similar but not identical to this has been dismissed in the past because it didn’t control for other factors, but this research did, yet the pattern still emerged. That is why lead researcher Hans de Kroon believes its time to take this problem seriously because, if neonicotinoids are indirectly harming birds, they’re probably harming other wildlife that prey on insects, too.

David Gouslon of the University of Sussex, who wasn’t involved in this study but did write a separate commentary, says this research is convincing. He tells the Guardian: “The simplest, most obvious, explanation is that highly toxic substances that kill insects lead to declines in things that eat insects. … This work flags up the point that this isn’t just about bees, it is about everything. When hundreds or thousands of species or insect are being wiped out, it’s going to have impacts on bats, shrews, hedgehogs, you name it. It is pretty good evidence of wholesale damage to the environment.”

Goulson also highlights that unlike the Netherlands, the UK (and much of Europe) isn’t monitoring neonicotinoid pollution. The UK agency responsible for overseeing matters dealing with the environment and wildlife, called Defra, remains stalwart that the research isn’t overwhelming and that, at the moment, there isn’t compelling evidence to show a definite link between neonicotinoids and harm to wildlife.

Defra says that these kinds of pesticides are safe when used as recommended and points to the admittedly (usually) rigorous short-term trials carried out by neonicotinoid producers. The problem though is precisely that they are only short-term trials. Manufacturers haven’t used longer-term systematic trials but if they did, scientists say the data would show the harms neonicotinoids can create over longer periods of time.

It was hoped that this message was, at last, getting through, when in 2013 the EU imposed a two-year suspension of thre neonicotinoids, but it emerged the suspension is largely toothless because the EU is failing to track data during this time, and a two year suspension is unlikely to give any meaningful data anyway.

We have to be clear that this latest study implies a link and not causation, but because this adds to a wider body of data that all suggests a link, the evidence for probable causation is growing ever more formidable. All this leads us to ask: how much scientific data do we need, and how many impartial experts need to speak out, before our politicians will act?

Or perhaps the better question is, how many animal populations have to collapse before our governments see fit to do something and actually tackle the issue of neonicotinoids?

Spokane Washington bans neonicotinoid pesticides

Another City Has Made Its Public Spaces Safer for Bees

Spokane, Wash., is the latest city to pass an ordinance limiting the use of neonicotinoid pesticides.

 

It’s happening very slowly, one midsize to large city at a time, but the Pacific Northwest is inching its way toward becoming a haven for honeybees. Earlier this week, Spokane, Wash., joined Eugene, Ore., and Seattle in passing citywide bans on neonicotinoids, a class of pesticide that’s widely believed to be harming the pollinators that play such an important role in our agriculture system—a full 33 percent of the crops grown worldwide depend on honeybees.

The 5–2 city council vote (the dissenting votes came from two councilmembers who said the research wasn’t convincing enough) came just after Pollinator Week, amid a rush of bee-related news. There was President Obama’s announcement of a Pollinator Health Task Force, a preview of a report that says neonics are worse for bees than DDT, and another study that showed that the supposedly bee-friendly plants you can purchase at major retail chains contain high levels of the pesticide. Eight years after the first instances of colony collapse disorder occurred, sparking increased interest in pollinator health among both scientists and environmentalists, it appears that new momentum is building behind efforts to protect bees.

In Spokane, the new ordinance won’t cover all city-owned land, as the parks department manages a chunk of public property, but it has assured City Council President Ben Stuckart that neonics aren’t being used in Spokane’s parks. The ordinance mandates that “no department may knowingly purchase or use products or products in packaging containing neonicotinoids,” but it does not apply to personal use of the pesticide on private property.

“This ordinance simply says Spokane prioritizes the protection of our food supply over the ornamental use of pesticides,” Stuckart said in a statement.

Spokane may not have a vested economic interest in protecting honeybees, but Washington state certainly benefits from the estimated $15 billion in increased crop value the bees bring with their highly efficient pollination. The state is the country’s leading apple producer, and the 175,000-some acres of orchards that grow there depend on a healthy population of honeybees and other insects to yield a good crop.

What remains unclear is whether limiting the use of neonics will help stem the nearly one-third of managed beehives that die off every year, on average. Dave Goulson, a professor at the University of Sussex in England, who worked on the latest neonic study, told the BBC he wasn’t in favor of an outright ban. “I think we should use them much more judiciously,” he said. Dennis vanEngelsdorp, a bee researcher at the University of Maryland, told me something similar, saying, “I think it’s a little bit naive to think that if we ban neonics, all of our problems will go away.”

The federal Pollinator Health Task Force doesn’t promise any sweeping ban, but perhaps the local actions of cities like Spokane can help propel more measured reforms—ones that could bring limits on neonics and other chemicals that are harmful to bees—out of the city and onto farms.

Los Angeles Considers Legalizing Urban Beekeeping

By Krista Simmons in Food on Feb 12, 2014 12:45 PM

Urban beekeeping, along with other more typically rural pursuits like raising chickens and planting edible gardens, has become more popular as a part of the homesteading movement. Not only do urban beekeepers actually have several advantages over their rural counterparts—rural areas are doused with pesticides, they don’t offer the same variety of plants as cities and the bees don’t have to be trucked in to Los Angeles—but the bees are already here. They also have a more diverse, year-round source for pollen. Unfortunately, up until this point, beekeeping in city limits has been against the law.

Many have been campaigning to change that. And today the Los Angeles City Council voted unanimously to conduct a study on legalizing urban beekeeping in Los Angeles, according to City News Service.

The study would look into overturning the law banning beekeeping in areas where there are single-family homes. The council also passed a motion that calls on the city to explore more humane ways of removing bees other than extermination. A third motion passed supports federal protections for bees against pesticides.

Councilman Paul Koretz said the state has been losing a third of its bees a year since 2006, threatening California’s avocado and almond growing industry.

“Almonds alone are $4 billion of our state’s economy,” he said. “Bees, it turns out, are thriving in Los Angeles, he said, possibly because there is no large-scale agriculture and fewer pesticides in use. “It’s important to protect these bees that thrive here locally.”

Beekeeping proponents showed up to the City Council meeting to show their support. The LA Times’ Emily Alpert Reyes said there was at least one beekeeping outfit and a fair number of bee costumes, including a doggie bee costume in attendance this morning.

“Bees are in real trouble, and urban beekeeping is part of the solution,” Rob McFarland of HoneyLove, an organizing supporting bee farming in Los Angeles, told the City Council.

Hopefully the buzz will turn into a sweet resolution for city dwellers and aspiring hive owners alike.
