Topical issues: nature

Our natural world is under assault from human activity. The trouble is, to recognise damage to nature reveals also the risk to ourselves. ‘Progress’ is in the hands not of individual people, nor their elected representatives and politicians. It is in the hands of the free market, the large corporates who set the direction of our world through creating profit streams however they can. We don’t have to identify this as evil; rather it is almost inevitable. We are persuaded of the benefits of convenience and consumerism, and we are the source of the profits and the stimulant to corporate behaviour and the setters of social trends. What we must do is to observe, to ask questions, and be honest enough with ourselves to recognise that nothing we do is without consequence. If we are custodians of our children’s futures, we must accept individual and joint responsibility for the condition of our planet.

Decline of bees, UK and worldwide

‘Honeybees will die out in Britain within a decade as virulent diseases and parasites spread through the nation’s hives, experts have warned. Whole colonies of bees are already being wiped out, with current methods of pest control unable to stop the problem.

‘The British Beekeepers Association (BBKA) said that if the crisis continued, honeybees would disappear completely from Britain by 2018, causing “calamitous” economic and environmental problems. ... Last year, more than 11 per cent of all beehives inspected were wiped out, although losses were higher in some areas. In London, about 4,000 hives – two-thirds of the bee colonies in the capital – were estimated to have died over last winter. Of the eight colonies inspected so far this year, all have been wiped out. ...’


Massive and sudden declines have occurred in bee populations across the world in 2006-2007. Honeybees sustain agriculture through pollination so human food supply depends on their well-being.

Sudden and wholesale loss of bee colonies is described as Colony Collapse Disorder, but does not explain the reason. Primary reasons suggested, and sometimes in the past confirmed, include parasitic mites and consequent viruses. More recently pesticides, GM crop use and climate change have been suggested. However, as this page seeks to demonstrate, the electromagnetic environment is also crucially influential on honeybees, and is undergoing rapid and enormous change from human communications systems.

  • Infestations such as the varroa mite can be tested for quickly and easily, and could confirm this as the current cause, but this has not been reported this time.
  • Pesticide use has not been suddenly altered across the world (Switzerland, Poland, Italy, Germany, Greece, the UK and 24 states of the USA).
  • Agricultural methods are more intensive: hives may be fumigated, electric fan-ventilated, permanently illuminated, bees fed on the wrong sugar solutions over winter, and grown to be over-sized.
  • GM crops have been introduced, and not always as openly as some would like. These indeed can affect insect balance, but again this has not been evenly building across all the affected areas and would be more localised.
  • Climate change is undoubtedly altering plant diversity and honeybees can be very specific, but this would suggest more gradual population density movements rather than disappearance.

The sudden declines are marked by bee disappearance rather than just hives full of dead and diseased bees. The empty hives are not plundered by neighbouring colonies and other insects are not filling the pollination gap. This leaves two further possibilities:

  • the hives are acting as a deterrent to bee return
  • the bees are losing the ability to navigate or communicate.

Nothing in the bees, hives or honey is pointing to chemical toxicity or bio-predation. Since the studies lower down this page show that honeybees depend on natural electric and magnetic fields, and that they are frequency-specific in their communications, it is urgent that this line of enquiry is opened up.

Whilst the last bee species extinction in the UK occurred in 1988, there has been a steady decline in the bee population.

It’s a particularly bad time to cut funding on bee inspectors, but this is exactly what has happened in the UK: Funding cuts threaten bee health (2004).

Bees are not just nice to have around and make honey; they are crucial to crop pollination and a vital element in agriculture and food production. The global economic value of pollination may be as much as £50bn. In June 2006 it was reported that bee decline may hit food crops in Northern Ireland, and the UK in general. The cause appears to be mites and late flowering losing synchronicity with the bees’ nesting cycle. Farmers have been making efforts to restore habitat (eg field margins), and some decline appears to be restored.

Why this is not just interesting, but a critical issue: ‘Approximately 80% of all insect pollination is accomplished by honey bees. According to the University of California at Davis publication “Don’t Underestimate the Value of Honey Bees,” the remaining 20% of other insect pollinators are drastically reduced in number as well, making one wonder if the problem is the varroa mite or something else affecting the broader insect world.’ [Source: Suite 101]

Then in February of 2007 the bad news arrived of massive colony collapses across the US:

In Austria, an enquiry was made via the beekeepers’ newspaper. 25 replied that they encountered problems after mast installations in the proximity:

  • 37.5% reported an elevated bees aggressiveness
  • 25.0% reported a tendency of bees to leave the hive
  • 62.5% reported the collapse of the bee population.

No-one knows why

Pesticides and habitat?

Central to the argument of pesticide use has been Imidacloprid [more], a systemic nicotinoid agent that accumulated across harvest seasons and becomes available to pollinators. It attacks the nervous system, affecting learning and memory. See: Honey Bee Disappearances: Could Pesticides Play A Role?. Apparently after nicotinoids were withdrawn in France in 1994, bee colonies have still not yet fully recovered.

Whilst pesticides and loss of habitat appear mostly to blame, it isn’t just farmers who can make a difference. Growing traditional plants in gardens would help, but we must remember that climate change is already visible, with the migration of many species (butterflies, insects, birds, fish etc.) all on the move, in a northerly direction. It may be worth considering therefore, the predictions about domestic gardens and the change to mediterranean plant varieties.

Another possibility is that agricultural methods, including bee-keeping is increasingly monocultural, reducing variety in both bee populations and the nectar they collect. See: A surprising decline of pollination services in USA. One factor in agricultural methods is bee size, and this does appear to make a difference in their resilient to mites. By pushing cell sizes up, commercial beekeepers develop bees up to 50% larger, that ostensibly are more productive. However, pushing this boundary has led to greater varroa problems that organic, natural-sized bees just do not suffer. [Opinions from an organic beekeeper.]

Some have pointed to GM crops, but this does not explain either the 20 year trend, the international aspect, or the suddenness of the 2006 USA event:

Furthermore the bees have not just been dying in the hives, or being found dead, they have just been disappearing in their millions.

April 07, Palm Beach News reported: ‘Troy Fore [executive secretary of the American Beekeeping Federation] and other bee industry figures and scientists said the phenomenon resembles many of the ways bees have always died, but for one notable exception: the empty hive is shunned by other bees and also by insect scavengers.

‘“I was very much a skeptic about this thing when I first heard of it,” said Danny Weaver, a Novosota, Texas, bee breeder who is president of Fore’s group.

‘He said his skepticism vanished when he obtained honeycomb from a collapsed hive and put it in an area heavily populated with bees and bee parasites, including wax moths.

‘“Nothing would go near it,” Weaver said. “Ordinarily, other bees would be robbing that honey, moths would be all over it. But nothing.”’

Urgent investigation required

This observation must be tested further. A comb from a deserted hive and a comb from a thriving hive must be placed together where other species are plentiful.

  • If the ‘affected’ comb is rejected but the ‘control’ is robbed, then this indicates the issue is embedded in the comb, not with the bees.
  • If the comb and honey are then separated, each could similarly be tested for its influence on bees.
  • If neither comb attracts other than opportunistic attention, then either the environment is disturbing normal activity or the bees and moths are being affected by something in the environment around the combs.
  • The combs could then be tested separately to determine if one is itself influencing the environment of the other.

Since this is easily repeatable in many sites, it would quickly focus attention where it is due: comb, honey, pollinators or surrounding environment. (See below on bees, EM fields and their sense of smell.)

A man-made electromagnetic environment?

One trend that also causes concern is the electromagnetic environment. Ironically, power line pylons provide agricultral margins that are a haven for bees. In the US, it has been proposed that utilities do not mow the power line strips in order to halt the US decline in bees. Studies by Ulrich Warnke on bee behaviour in low frequency fields have, however shown supressed metabolic rates in bees, and a paper by J O Husing, ‘Biene und Elektrizitat’ in Imkerfreund (Beekeeper Friend) in 1965 noted effects of low frequencies on bee behaviour patterns. See also Bee World, 1976: Effects of Electric Charges on Honeybees.

There has been a deal of research on other insects, some relating to dimensional aspects on insect antennae. T Jaski noted in 1960 (‘Radio waves and life’, Radio Electronics, 31. pp. 43), that orientational reactions were observed in large ants when exposed to a SHF field of 10,000 MHz. They oriented their antennas along this electric lines of force and lost their ability to communicate the location of food to others. It was noted that the antenna length of the ants used in these experiments was almost a quarter of the wavelength to which they were they were exposed.

High electric fields present a greater problem in conductive hives (Bidokas et al., 1988). But it may not be hives and electrical fields that add to bee problems, so much as magnetic fields. Bees have a magnetoreception system sensitive down to 26nT at 10 to 60Hz, according to Kirschvink et al. (1997), decreasing rapidly with increasing frequency. Maybe living under power lines isn’t a completely good idea. Balmori 2006, ‘Effects of the Electromagnetic Radiation emitted by Mobile Telephony on Insects; Ecosystems’ recounts the effect of mobile phone antennas on insects more generally.

Are EM fields to blame? This is one environmental burden that matches the decline of bees, and the rapid recent rise in universal infrastructures may explain more.

Bees that vanished when a house went wireless

There was only one snag with Ryan Ferguson’s new home, a three-storey Georgian house in Bath. When the 29-year-old digital sales director moved in three years ago, he found 30 nests of bees in his attic. ‘They got everywhere𔄩, he says. ‘In the shower, the windows, the light fittings. It used to be quite dangerous. You would walk about at night without shoes on and they’d be all over the floor.’

He twice called in exterminators, but the bees just came back. Then, last summer, he installed a WiFi system. They left and never returned.

Explore the bee crisis more

As the months have gone by, the expected confirmations of mites or other parasites have not been forthcoming. Autopsies on bees show totally destroyed immune systems. Correlation with GM crops does not appear to be true, and whilst originally organic bees appeared immune, now it seems they are not. Beekepers say that the stresses of breeding, transport, winter syrup nutrients are nothing new. Historical ‘dwindles’ or disappearances have always been due to known pathogens.

One beekeper in the US has imported Australian bees and placed them in untreated, sterilised and irradiated abandoned hives. In the latter the bees thrived, suggesting a biological factor. However, with still so much uncertainty and no identified single pathogen, a combination of factors may well be the best explanation: the ‘perfect storm’ where all the wrong things come together at the same time with a catastrophic result.

Bees are frequency-sensitive, like all living organisms:

It is interesting to reflect that many people complain of ‘the hum’, relating electromagnetic sources with an apparently acoustic phenomenon. There may indeed be more than one ‘hum’, but since bees are so sensitive to particular frequencies, this is a worthwhile route for research, especially if hives resonate in response to the now all-pervasive EM fields. GSM mobile phone systems produce a structural pulse frequency of 217Hz, DECT (cordlesss phones) 100Hz, TETRA 70.6Hz.

Research summary:

  • 2 beehives were unexposed and 2 beehives were exposed to a DECT phone.
  • 25 bees were selected from each beehive and released 800 meters away.
  • Unexposed beehives: 16 and 17 bees returned after respectively 28 and 32 minutes.
  • DECT-exposed ones: 6 bees returned after 38 minutes to one hive. The other hive remained deserted.
  • In the exposed beehives, there were 21 per cent fewer cells constructed in the hive frames after 9 days.

Bees rely on key enzyme for their sense of ‘smell’ in their antennal lobes:

It is interesting that the interpretation given in the February 2007 US news (above), is that the bees left in the hive being so diseased is due to immuno-suppression. If you take a look at our health pages under EM Fields you will see the evidence that electromagnetic fields (EMF) affect the behaviour of key enzymes that produce and regulate nitric oxide in living organisms, and why this is so important. If this is true of insects, then this avenue of research is also vital.
