(Reuters) The European Commission decided not to renew approval for thiacloprid. The Commission based its assessment on findings of the European Food Safety Agency published in January last year. The findings highlighted concerns about the active substance being toxic for humans and present in too great a concentration in ground water. The pesticide also harms bees and bumblebees, weakening their immune systems and impairing their reproduction, the findings said.
(British Ecological Society) Researchers found that exposure to chronic low-dose radiation, similar to levels found in the Chernobyl exclusion zone, negatively affects bumble bee energy use by increasing their metabolic rate and food consumption. “An increase in nectar consumption for an individual bee could have important ecological consequences…”
(Julius-Maximilians-Universität) Wild populations of the western honey bee were widely assumed to be extinct in Europe. “However, recent fieldwork studies reveal that wild honey bees still exist in forests: Their colonies mainly nest in tree cavities.” So far, wild honey bees have only been observed in northern Poland and Germany, but new research estimates there could be as many as 80,000 wild honey bee colonies in European forests.
(EU News) The Environment, Public Health and Food Safety Committee for the European Union on Tuesday approved a resolution highlighting weaknesses in the EU Pollinator Initiative that render it inadequate to address the main causes of pollinators’ decline in Europe. The committee proposes that a reduction in the use of pesticides be set as a “common indicator” to evaluate how effective national measures are in protecting bees and other pollinators. To help further decrease pesticide residues in bee habitats, members of the European Parliament want the reduction of pesticide use to become a key part of the future Common Agricultural Policy.
(CNRS) Despite a 2013 moratorium on the use of neonicotinoids in the European Union, residues of these insecticides can still be detected in rape nectar from 48 percent of the plots studied, their concentrations varying greatly over the years. These findings indicate that persistent use of neonicotinoids with certain crops in open fields threatens bees and pollinators frequenting other, untreated crops; they confirm that residues remain and spread in the environment.
(StarTribune) The European Parliament on Wednesday blocked a diluted proposal by the 28-nation bloc’s executive arm on protecting bees from pesticides, arguing it didn’t go far enough. European lawmakers adopted a resolution urging the European Commission to “table new legislation based on the latest scientific and technical knowledge.” They said the Commission weakened its initial proposal due to the opposition of 16 member states which did not want provisions in the draft on how pesticides should be tested to protect bees from chronic exposure.
(Bloomberg Environment) The European Union plans to tighten the criteria it uses to assess how harmful pesticides may be to honey bees, potentially making it harder for manufacturers to get authorized for some of their products. The tighter criteria would become mandatory when evaluating how pesticides affect bees in the short-term, under a draft rule the European Parliament’s environment committee discussed Sept. 25.
