Global Simultaneous Die-Offs of Multiple Species

This great article in two parts, from Australia, details the mass die-offs around the world, of many species - including the beautiful Ladybird Beetle that is surprisingly important to the web of life: Original Articles at: Part One: http://hydroponics.com.au/free-articles/where-have-all-the-ladybirds-gone and Part Two: http://hydroponics.com.au/free-articles/where-have-all-the-ladybirds-gon...

Where have all the ladybirds gone? Part 1

By Marilyn Steiner and Stephen Goodwin

In this two-part article, the authors shine a spotlight on neonicotinoid pesticides against a backdrop of widespread use of this group and concerning reports of an alarming and increasing loss of biodiversity. While honey bees have been the focus of concern, other pollinators and invertebrates, birds and even the lowly earthworm are at risk.

Major Study: Multiple Routes of Pesticide Exposure for Honeybees Living Near Agricultural Fields

A major new study from Purdue University researchers highlights that honeybees face a long list of pesticide dangers near agriculture. Multiple toxic agents combined, via several simultaneous routes of exposure mean bees are in peril from many sources.

Toxic food.

I'm concerned that our food would be toxic in multiple ways simultaneously.

Imidacloprid contaminates the pollen of seed-coated crops : A high risk for bees

Conclusions for Imidacloprid (Gaucho) :

  • A long persistence / soils (t1⁄2 = 9 months)
  • An uptake in flowers (mean level at 7 ng/g)
  • Mean level at 2-3 ng/g in pollen
  • Subletal effects at 2-4 ng/g (4 days)
  • Chronic mortality from 0.1 ng/g (10 days)
  • Main metabolites as much toxic as imidacloprid for bees
  • High risk for the beehives (PEC/PNEC >> 1)
  • Synergies with other pesticides, pathogens and parasites
  • Generalization of these results to nicotinoids and pyrazoles (clothianidin, thiamethoxam, fipronil...)
