America’s agricultural landscape is now 48 times more toxic to honeybees, and likely other insects, than it was 25 years ago, almost entirely due to widespread use of so-called neonicotinoid pesticides, according to a new study published today in the journal PLOS One. This enormous rise in toxicity matches the sharp declines in bees, butterflies, and other pollinators as well as birds, says co-author Kendra Klein, senior staff scientist at Friends of the Earth US. “This is the second Silent Spring.
Gisteren werd een motie door de Tweede Kamer aangenomen waarin de regering wordt opgedragen om in Brussel van positie te veranderen, en nu de invoering van de Bee Guidance te steunen. De Bee Guidance is een Europees richtsnoer dat beoogt bestrijdingsmiddelen beter te testen op hun schadelijkheid voor bijen en hommels. ‘Minister Schouten [Landbouw] zal haar beleid nu 180 graden moeten wijzigen,’ zegt Esther Ouwehand van de Partij voor de Dieren, die de motie indiende.
Experts from Suffolk Wildlife Trust, Buglife and the RSPB have all pointed to species in danger of disappearing from East Anglia. They include stone curlew - only 202 pairs nested in the East of England last year; the shrill carder bee - common in the region 25 years ago but now found only in the Thames Gateway area; and the crested cow-wheat - a plant limited to a small number of roadside verges because grassland has disappeared to farming or construction. Indeed, habitat destruction and human disturbance are cited as the two most common reasons these species are on the brink.
Sie werden immer weniger: Eine Biene auf einer Blüte. Doch der Einsatz von Pestiziden in der Landwirtschaft macht den Insekten zu schaffen. Der Rückgang der Insekten im Werra-Meißner-Kreis ist dramatisch. Hauptursache sei der massive Einsatz von Pestiziten in der Landwirtschaft, so Wolfram Brauneis, Naturschützer und Ornithologe.
The American Bumblebee—a species once more commonly seen buzzing around Southern Ontario—is critically endangered, according to a new study led by York University. The finding, published in Journal of Insect Conservation, found the native North American species, Bombus pensylvanicus, is facing imminent extinction from Canada, considered the highest and most at-risk classification before extinction.
A widespread loss of pollinating insects in recent decades has been revealed by the first national survey in Britain, which scientists say “highlights a fundamental deterioration” in nature. The analysis of 353 wild bee and hoverfly species found the insects have been lost from a quarter of the places they were found in 1980. A third of the species now occupy smaller ranges, with just one in 10 expanding their extent, and the average number of species found in a square kilometre fell by 11.
In Michigan, half of its bumblebee species have declined by 50 percent or more, Michigan Radio reported. "Of those twelve species, about half of them have declined and the other half are stable," Thomas Wood, a post-doctoral research associate at Michigan State University, told the radio station. Of the six species that have declined, their numbers dropped by more than 50 percent, Wood added. One species, the rusty patched bumblebee (Bombus affinis), has even gone extinct in Michigan. In 2017, the U.S.
Twelve pesticides made with chemicals shown to harm bees and other pollinators are slated to be banned as part of a proposed settlement with the manufacturers, the EPA announced Dec. 12. The pesticides, marketed by Syngenta AG., Bayer AG, and Valent USA Corp., contain either thiamethoxam or clothianidin, two chemicals in the neonicotinoid class that are linked to declining bee populations.
