Canadian beekeepers are suing the makers of popular crop pesticides for more than $400 million in damages, alleging that their use is causing the deaths of bee colonies.
The proposed class action lawsuit was filed Tuesday in the Ontario Superior Court on behalf of all Canadian beekeepers by Sun Parlor Honey Ltd. and Munro Honey, two of Ontario’s largest honey producers, the Ontario Beekeepers Association announced Wednesday.
“The goal is to stop the use of the neonicotinoids to stop the harm to the bees and the beekeepers,” said Paula Lombardi, a lawyer with London, Ont.-based law firm Siskinds LLP, which is handling the case.
As of Thursday morning, more than 30 beekeepers had signed on to participate in the class action.
The lawsuit alleges that Bayer Cropscience Inc. and Syngenta Canada Inc. and their parent companies were negligent in their design, manufacture, sale and distribution of neonicotinoid pesticides, specifically those containing imidacloprid, clothianidin and thiomethoxam.
The pesticides, which are a neurotoxin to insects, are widely coated on corn, soybean and canola seeds in Canada to protect the plants from pests such as aphids. Studies have shown that bees exposed to the pesticides have smaller colonies, fail to return to their hives, and may have trouble navigating. The pesticides were also found in 70 per cent of dead bees tested by Health Canada in 2013.
The European Commission restricted the use of the pesticides for two years and Ontario has indicated it will move toward regulating them, due to concerns over bee health.
Bayer maintains that the risk to bees from the pesticide is low, and it has recommended ways that farmers can minimize bees’ exposure to the pesticide.
Both Bayer and Syngenta told CBC News they wouldn’t comment on the lawsuit because they haven’t yet been served with it.
The lawsuit is seeking more than $400 million in damages, alleging that as a result of neonicotinoid use:
- The beekeepers’ colonies and breeding stock were damaged or died.
- Their beeswax, honeycombs and hives were contaminated.
- Their honey production decreased.
- They lost profits and incurred unrecoverable costs, such as increased labour and supply costs.
Beekeepers or companies involved in beekeeping services such as honey production, queen bee rearing and pollination who are affected and want to join the lawsuit are asked to contact Lombardi.
The Ontario Beekeepers Association is not directly involved in the lawsuit, but along with the Sierra Club Canada Foundation, helped connect beekeepers with the law firm. The association also helped with the research for the lawsuit.
February 11, 2014 – News Release
Once the snow melts, Canada’s bee population will be back in business — pollinating, making honey and keeping busy doing bee things. For at least two urban bee species, that means making nests out of plastic waste.
A new study by a University of Guelph graduate and a U of G scientist reveals that some bees use bits of plastic bags and plastic building materials to construct their nests. The research was published recently in the journal Ecosphere.
It’s an important discovery because it shows bees’ resourcefulness and flexibility in adapting to a human-dominated world, says lead author Scott MacIvor, a doctoral student at York University and a 2008 U of G graduate.
“Plastic waste pervades the global landscape,” said MacIvor. Although researchers have shown adverse impacts of the material on species and the ecosystem, few scientists have observed insects adapting to a plastic-rich environment, he said.
“We found two solitary bee species using plastic in place of natural nest-building materials, which suggests innovative use of common urban materials.”
Figuring out that the bees were using plastic in place of natural materials took some detective work by U of G’s Andrew Moore, supervisor of analytical microscopy at Laboratory Services.
Moore analyzed a grey “goo” that MacIvor discovered in the nests of one kind of bee, Megachile campanulae, which uses plant resins to build its nests,
“Scott thought it might be chewing gum originally,” Moore said. His team uses a scanning electron microscope to take highly detailed pictures of items, x-ray microanalysis to determine the elements in the sample and infrared microscopy to identify polymers. They can distinguish the finest detail on the surface of an animal hair.
Turns out that M. campanulae was occasionally replacing plant resins with polyurethane-based exterior building sealant, such as caulking, in its brood cells–created in a nest to rear larvae.
The researchers also discovered another kind of bee, Megachile rotundata, an alfalfa leafcutter, was using pieces of polyethylene-based plastic bags to construct its brood cells. The glossy plastic replaced almost one-quarter of the cut leaves normally used to build each cell.
Markings showed that the bees chewed the plastic differently than they did leaves, suggesting that the insects had not incidentally collected plastic. Nor were leaves hard to find for the bees in the study.
“The plastic materials had been gathered by the bees, and then worked – chewed up and spit out like gum – to form something new that they could use,” Moore said.
In both cases, larvae successfully developed from the plastic-lined nests. In fact, the bees emerged parasite-free, suggesting plastic nests may physically impede parasites, the study said.
The nests containing plastic were among more than 200 artificial nest boxes monitored by MacIvor as part of a large-scale investigation of the ecology of urban bees and wasps, a project involving numerous citizen scientists.
The nest boxes are located in Toronto and the surrounding region in backyards, community gardens and parks and on green roofs. They are used by a variety of bee species.
“The novel use of plastics in the nests of bees could reflect the ecologically adaptive traits necessary for survival in an increasingly human-dominated environment,” MacIvor said.
