For several years, we have been attracting the attention of policymakers but also to a wider audience in the highly dangerous, for many reasons and in many modalities, systemic pesticides placed on the market since today more than 20 years. If the public was aware of it via the issue of bees, there are many other areas that suffer the negative consequences of the use of these poisons, since the loss of biodiversity to human health through the birds and entire aquatic environment. The Task Force on Systemic Pesticides, international consortium of fifty scientists from fifteen countries is about to release a study on uplifting the multiple consequences of these pesticides. Stéphane Foucart, journalist in the world, we present the work.
"J e think I had to wake up in the mid-2000s. One day while I was walking near my home, in the scrub, I wondered what had happened to insects, home shopping network because it seemed that there was much less than before, says Maarten van Bijleveld Lexmond. And then I realized there were also less stuck to the windshield home shopping network and grille of my car. Almost, actually. "In July 2009, at his home in Notre-Dame-de-Londres (Hérault), Dutch biologist, 77 years, brings together a dozen entomologists sharing the same concern.
All noted an accelerated decline of all insect species since the 1990s. According to them, the collapse of honeybee is only the visible part of this phenomenon, with considerable consequences for the entire ecosystem. home shopping network
"After a long day of discussions, we decided to look at everything that was published in the scientific literature on systemic insecticides called" neonicotinoids, "he continues. This new generation of molecules, placing on the market in the 1990s, we seemed to be a decisive factor home shopping network to explain the situation. "
Still had to support this suspicion. Over the months, the small group of researchers has become an international consortium - the Working home shopping network Group on systemic pesticides (TFSP for Task Force on Systemic Pesticides) - fifty scientists from 15 countries, mostly university or researchers within public home shopping network bodies, all having joined the personae of intuiti panel. OUR AGRICULTURAL ENVIRONMENT AND NATURAL THREATENED
The result of their five years of work, to be published in the next edition of the journal Environmental Science and Pollution Research, was to be released Tuesday, June 24 "The evidence is very clear, says Jean-Marc Bonmatin (Centre of Molecular Biophysics CNRS), member of TFSP. We are witnessing a threat to the productivity of our agricultural and natural environment. Far from secure food production, the use of neonicotinoids threatens pollinators that make it possible.

Overall, experts TFSP reviewed 800 studies published in the scholarly literature on these insecticides. They fired seven long thematic overviews on their modes of action, their fate in the environment, their impact on various organizations, etc..
These molecules (imidacloprid, thiamethoxam, clothianidin, fipronil but) now share about 40% of the global market for agricultural insecticides and represent a market of over 2.6 billion dollars (1.9 billion euros). They are first distinguished from previous generations by their toxicity, 5 000 to 10 000 times that of the famous DDT, for example.
Their mode of application is also different. These products are not only applied as sprays, but are also used in treatment of soil and seed dressing, as part of a systematic use
