I love this photograph of two pollinators visiting summer flowers. That’s a honeybee on the left, and a big, fat bumblebee on the right. I love to watch bees, all kinds of bees, and other pollinators enliven my garden. But you have probably heard that honey bees are severely threatened by a syndrome that has been named Colony Collapse Disorder. Although multiple causes may be implicated, the smoking gun points to one major culprit: neonicotinoid pesticides. And you can bet that it’s not just honeybees that are being affected. Other pollinators, birds and aquatic life are all at risk as well.

In Europe, precautionary bans of some neonicotinoids are being instituted.

The Ontario Beekeepers’ Association is supporting a call for a ban of neonicotinoids in Ontario. The banner, above, is from their website. You can sign their petition and read more information at ontariobee.com.

The Sierra Club of Canada is also supporting a ban. You can sign their petition and read more information at Sierraclub.ca.

The American Bird Conservancy have looked into the effect of neonicotinoids on birds.

ABC commissioned world-renowned environmental toxicologist Dr. Pierre Mineau to conduct the research. The 100-page report, “The Impact of the Nation’s Most Widely Used Insecticides on Birds,” reviews 200 studies on neonicotinoids including industry research obtained through the US Freedom of Information Act. The report evaluates the toxicological risk to birds and aquatic systems and includes extensive comparisons with the older pesticides that the neonicotinoids have replaced. The assessment concludes that the neonicotinoids are lethal to birds and to the aquatic systems on which they depend.

The beauty of bees and the desperate crisis that threatens them, and by extension, us, is documented in the award-winning video, The Vanishing of the Bees. I was able to borrow a copy from my local library and highly recommend it.

In addition to becoming informed and supporting a ban on neonicotinoids, you can help by buying local organic honey. Did you know that a lot of commercial honey isn’t pure? It has been ultra-filtered to disguise ingredients:

Ultra filtering is a high-tech procedure where honey is heated, sometimes watered down and then forced at high pressure through extremely small filters to remove pollen, which is the only foolproof sign identifying the source of the honey. It is a spin-off of a technique refined by the Chinese, who have illegally dumped tons of their honey – some containing illegal antibiotics – on the U.S. market for years.

In the U.S., the Food and Drug Administration says that any product that’s been ultra-filtered and no longer contains pollen isn’t honey. However, the FDA isn’t checking honey sold here to see if it contains pollen.

Food Safety News found that more than three-fourths of the honey sold in U.S. grocery stores had been ultra-filtered.

Helianthus ‘Lemon Queen’

I have many plants in my garden that are very popular with bees and other pollinators. Pictured above is a favorite, the perennial Lemon Queen Sunflower (Helianthus ‘Lemon Queen’), which blooms profusely in late summer.

I reserved one corner of the garden for a few plants that can be a bit unruly, but are beloved by pollinators. I call it Bee Corner. There are an assortment of monarda varieties. Monardas can be a bit rambling, and it is welcome to spread out at will here. There’s also some agastache ‘Black Adder’, which did very well this summer.

New to the corner are wild quinine (Parthenium integrifolium) and hairy mountain mint (Pycnanthemum pilosum). They’re both North American natives that attract pollinators and have settled in well. Next year, they can take engage in a turf war with the monardas.

All comers can feast without fear of poisoning. I never use pesticides of any kind on my plants. The plants are all strictly on their own, thrive or die, and mostly, they thrive.

Lately, Colony Collapse Disorder has been in the news, and the rise in the use of neonicotinoid pesticides and fungicides is suspected as a contributing cause. The jury is still out on the exact causes of honey bee die-offs and because of their economic importance, honey bees are getting a lot of attention. One thing is for certain though. It’s not just honey bees that are affected by rampant pesticide use.

As Bridget Stutchbury points out in Silence of the Songbirds, the banning of DDT didn’t end the threat of pesticides to species such as birds:

We are as hooked on pesticides today as we were in the 1960s, when, in her seminal book Silent Spring, Rachel Carson warned us of the rain of poison that was bringing death to our waters and killing thousands of birds…. In many ways, birds are in greater danger today than in the 1950s because modern pesticides are more lethal. Older OC pesticides (organochlorines, fat soluble pesticides that can be stored in the fatty tissues of animals) were replaced in the 1970s and 1980s by “safer” pesticides like organophosphates and carbamates. These pesticides are safer because they break down within a few days and are not stored in the body, and so do not accumulate in the food chain. But many, like monocrotophos, are vastly more toxic to birds (and people) than were the OC pesticides. Modern insecticides are designed to kill their target swiftly and then break down before “non-target” animals come into contact with the poison. This is easier said than done. Birds can be exposed to these insecticides via direct contact with sprayed plants, by eating insects and fruits in areas that have been recently sprayed, or by eating pesticides that are applied to the ground in the form of granules….We have traded persistence for toxicity.

Many insecticides are lethal to birds because they are neurotoxins and interfere with the nerve impulses inside the bodies of animals. They disrupt the signal that must jump from neuron to neuron via chemical messengers, causing severe shaking, then paralysis and asphyxiation. Pesticides that are effective in killing insects are also very toxic to birds and other animals, including humans.

Agastache ‘Black Adder’

You can help reduce the use of agricultural pesticides by buying organic foods. You may feel that buying organic items such as bananas is not worthwhile because you peel the bananas anyway. But by buying organic bananas you support the reduction of the pesticide burden where the bananas were grown. You can also step more lightly on the land by buying other earth-friendly products such as shade-grown coffee. For more on threats to birds and ways you can make a difference, Silence of the Songbirds is a great read.
