Stop Home Depot from downplaying bee-killing pesticides. Home Depot announced last year that it would require a label on plants grown with a family of pesticides that are worsening the bee die-off.

Stop Home Depot from downplaying bee-killing pesticides

Yet despite scientific concerns, here is how their label describes the effects: This plant is protected from problematic aphids, white flies, beetles, mealy bugs, and other unwanted pests by Neonicotinoids. No mention whatsoever of the harmful impact on honeybees, butterflies, or other pollinators! Pesticides : quand les abeilles ont le bourdon …

Les abeilles sont considérées comme les “reines de la biodiversité”.

Pesticides : quand les abeilles ont le bourdon …

Et pourtant, leur nombre continue de diminuer. La raison : un système d’agriculture intensive qui utilise à outrance des produits chimiques. Ce système est promu par des entreprises agrochimiques telles que Bayer, Syngenta ou encore BASF. Mobilisation de Greenpeace devant le siège de Bayer, en Allemagne Nous souhaitons démontrer que le modèle agricole actuel a des effets néfastes sur les abeilles. L’étude a révélé que plus des deux tiers du pollen prélevés dans les champs et ramenés à la ruche par les abeilles ouvrières ont été contaminés. Le redoutable “effet cocktail”

Pesticides et prise en compte politique (scientifique)

Frelon asiatique. Like a Bee to the Clover. The “Show Bees Some Love” actions in seven metropolitan areas attracted local and national media, drawing much-needed attention to the critical role pesticides play in decimating the world’s honeybee population.

Like a Bee to the Clover

Home Depot responded to the campaign, telling a CNBC reporter that the retail chain has been “working on” an alternative to neonicotinoids (the class of pesticides scientists now believe play a key role in Colony Collapse Disorder) for “some time,” and that several of its suppliers are already using replacements. We plan to hold their feet to the fire until they follow through. Meanwhile, Lowe’s is still giving us the silent treatment. We, along with our allies Friends of the Earth, SumOfUs.org, Pesticide Action Network and other groups, plan to keep the pressure on Home Depot and Lowe’s. Through petitions, letters, talks with the companies’ CEOs. And what about the U.S. GMOs Are Killing the Bees, Butterflies, Birds and . . . ? "It is ironic to think that man might determine his own future by something so seemingly trivial as the choice of an insect spray.

GMOs Are Killing the Bees, Butterflies, Birds and . . . ?

" - Rachel Carson, Silent Spring When the honeybees, our most important food pollinators, started dropping like proverbial flies, scientists scrambled to identify their killer (or killers). Attention eventually turned to the increased use of a class of pesticides known as neonicotinoids. Importante mortalité des abeilles: le cri d'alarme des apiculteurs ariégeois.

C’est reparti non pas comme en 14 mais comme en 2009!

Importante mortalité des abeilles: le cri d'alarme des apiculteurs ariégeois

Le danger ne vient plus de la plaine mais de la montagne. Depuis le début de l’hiver les apiculteurs ariégeois dénombrent plus d’un millier de ruches mortes ou très affaiblies (au total près de 3000 ruchers seraient hors service). Un constat qui s’alourdit inexorablement tous les jours et qui s’étend sur toute la chaîne des Pyrénées. Si bien que ces professionnels ont décidé de monter un collectif pour alerter les pouvoirs publics. Ils ont tenu ce jeudi une conférence de presse pour parler de leur situation devenue très critique.

Plant STD linked to honeybee collapse. It’s time to have a little talk about the flowers and the bees.

Plant STD linked to honeybee collapse

ASH/FDA Workshop in Clinical Endpoints in Multiple Myeloma - ReportHoneyBeeHealth.pdf. Common crop pesticides kill honeybee larvae in the hive. UNIVERSITY PARK, Pa. -- Four pesticides commonly used on crops to kill insects and fungi also kill honeybee larvae within their hives, according to Penn State and University of Florida researchers.

Ces produits tueraient seulement les espèces "nocives". Bien sûr que non ! Enfin si ce genre d'études peut prouver UNE FOIS POUR TOUTE que diffuser des pesticides, fongicides, herbicides, enfin bref tous ces produits soit-disant "phyto-sanitaires" (alors que ce sont de purs et simples poisons !) est nocif pour la totalité des êtres vivants et doit être proscrite on aura gagné. Mais que le chemin est long ! – alwen

Les abeilles sacrifiées sur l'autel de l'agriculture intensive. Les colonies d'abeilles connaissent une surmortalité depuis 20 ans.

Les abeilles sacrifiées sur l'autel de l'agriculture intensive

Les causes en seraient multifactorielles. Mais celles-ci ne ramènent-elles pas toutes à un mode de production agricole ? La question de la santé des abeilles interpelle les professionnels mais aussi la société civile, comme l'a montré le succès des rencontres scientifiques organisées par l'Agence nationale de sécurité sanitaire de l'alimentation, de l'environnement et du travail (Anses) le 21 novembre 2013 à Maisons-Alfort. La tapisserie tout entière. Bees can’t find flowers because of your car. As a species, we are not doing right by bees.

Bees can’t find flowers because of your car

They work so, so hard to pollinate the plants that form the basis for human existence, and, at every junction, we try to thwart them. A new study, for instance, has found that diesel fumes from cars essentially eliminate bees’ ability to smell flowers. If bees can’t smell the flowers, they can’t find them, which means they can’t feed off them or pollinate them, either. The researchers found, specifically, that the nitrogen oxides in diesel fumes mingle and react with flowers’ smell chemicals, changing them into other chemicals that are meaningless to bees.

The Guardian reports: The researchers strapped bees down and taught them to associate floral scents with food in the form of a sugar solution. Farm kills millions of bees with illegal pesticide spraying, gets slap on wrist. A huge Florida citrus farm is being fined by state officials for poisoning millions of honeybees to death — but it’s not being fined very much.

Farm kills millions of bees with illegal pesticide spraying, gets slap on wrist

Ben Hill Griffin Inc., one of the state’s largest growers and a supplier to Florida’s Natural orange juice, is accused of illegally spraying pesticides (i.e., not following the directions on the labels) in ways that led to the deaths of bees kept by nearby beekeepers. One apiarist told officials that the farm used crop-dusters to douse its groves at least a dozen times — presumably to control Asian citrus psyllid, which spreads the devastating citrus greening disease. Scientists discover another cause of bee deaths, and it's really bad news. So what is with all the dying bees? Scientists have been trying to discover this for years. Meanwhile, bees keep dropping like... well, you know.

Is it mites? Pesticides? Cell phone towers? Quartz reports: 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. The researchers behind that study in PLOS ONE -- Jeffery S. The discovery means that fungicides, thought harmless to bees, is actually a significant part of Colony Collapse Disorder. And it is not just the types of chemicals used that need to be considered, but also spraying practices. The authors write, "[M]ore attention must be paid to how honey bees are exposed to pesticides outside of the field in which they are placed. The Mystery of Bee Colony Collapse.

What's tipping honeybee populations into huge annual die-offs? For years, a growing body of evidence has pointed to a group of insecticides called neonicotinoids, widely used on corn, soy, and other US crops, as a possible cause of what has become known as colony collapse disorder (CCD). Rather than kill bees directly like, say, Raid kills cockroaches, these pesticides are suspected of having what scientists call "sub-lethal effects"—that is, they make bees more vulnerable to other stressors, like poor nutrition and pathogens. In response to these concerns, the European Union recently suspended most use for two years; the US Environmental Protection Agency, by contrast, still allows them pending more study. But according to a new peer-reviewed paper, neonicotinoids aren't the only pesticides that might be undermining bee health. But it was the fungicides that caused the most concern in the second part of the experiment.

E.U. bans another bee-killing insecticide. Antibiotiques et pesticides : un cocktail mortel pour les abeilles américaines - LeMonde.fr#xtor=EPR-32280229-[NL_Titresdujour]-20111106-[titres]#xtor=EPR-32280229-[NL_Titresdujour]-20111106-[titres]#xtor=EPR-32280229-[NL_Titresdujour]-20111106-[titres] Leruisseau - Antibiotiques et pesticides : un cocktail mortel pour les abeilles américaines. Common Pesticide Makes Honey Bees Picky Eaters. A new study offers further evidence about the dangerous effects of pesticides on honey bees. Biologists at the University of California at San Diego have found that a commonly used crop pesticide makes honey bees picky eaters and also makes them reduce the number of waggle dances they perform.

Waggle dances are how the bees communicate the location of a food source; bees exposed to the pesticide performed four to ten times fewer dances. Indeed, as Daren Eiri, a graduate student and the first author of the study in the Journal of Experimental Biology, says, some bees simply stopped performing waggle dances altogether after exposure to pesticides. The chemical in question is imidacloprid, which is a type of neonicotinoid — which has been linked to bees’ deaths. Imidacloprid has come under increasing scrutiny in the US and is banned for use in some crops in some parts of Europe. Heather Pilatic: Widely-Used Pesticides Killing Bees. Bees are still dying and EPA is still sitting on its hands. Luckily for those of us who like to eat, scientists have been hard at work cracking the "mystery" of colony collapse disorder (CCD). Today two new studies were published in Science, strengthening the case that neonicotinoid pesticides are indeed key drivers behind recent pollinator declines.

To avoid in advance some of the inevitable confusion on this topic, nobody is saying that neonicotinoids are the culprit behind CCD. Sharp bee population decline 'linked to pesticides' Entomologists: “Stop feeding corn syrup to honeybees.” Duh. If you want to a kill a honeybee hive’s buzz, take all its honey away and feed the bees a steady diet of high-fructose corn syrup.

Believe it or not, apiarists have been doing just that since the 1970s — feeding HFCS to their colonies as a replacement source of nourishment for the honey that gets taken away from them to be sold. And believe it or not, HFCS, which is bad for humans, is also bad for honeybees.
