Yes, organic bees survive CCD, which almost proves that a pesticide (or maybe GM plants) must be responsible for CCD.
Also living on refined white sugar and high-fructose corn syrup in winter certainly can kill any advanced life-form.
Disease and low genetic diversity might have caused US bumblebee decline over the past few decades, say scientists
The abundance of four common species of bumblebee in the US has dropped by 96% in just the past few decades, according to the most comprehensive national census of the insects. Scientists said the alarming decline, which could have devastating implications for the pollination of both wild and farmed plants, was likely to be a result of disease and low genetic diversity in bee populations.
Bumblebees are important pollinators of wild plants and agricultural crops around the world including tomatoes and berries thanks to their large body size, long tongues, and high-frequency buzzing, which helps release pollen from flowers.
Bees in general pollinate some 90% of the world’s commercial plants, including most fruits, vegetables and nuts. Coffee, soya beans and cotton are all dependent on pollination by bees to increase yields. It is the start of a food chain that also sustains wild birds and animals.
