Endangered Bees

Scientists are sounding the alarm. 

Bees and other pollinating insects have their number dropped alarmingly, putting their future survival at risk, and could have dramatic consequences for ecosystems and agriculture.

More and more scientific studies suggest that changes in farming practices could make bee populations vulnerable to pests and parasites, dangerously increasing mortality rates. Changes in pesticide use could even be responsible for the collapse of entire bee colonies.

Effects of pesticides on honeybee hives

INRA (National Agronomic Research Institute) researchers have recently shown that it is the combination of an infectious agent and an insecticide that threatens hives. A deadly cocktail that should require a review of the procedure for the evaluation of pesticides.

The imidacloprid, the active agent of the Gaucho, a systemic insecticide, and Nosema Ceranae and a microparasite of the bowel weaken together bees or kill them massively.

This was shown by Cédric Alaux, Yves Leconte and their colleagues at INRA Avignon, in a previous study curiously unnoticed: “Our study shows that if they are contaminated with Nosema, bees exposed to Imidacloprid even in minute quantities, succumb to Nosema” said Yve Leconte.

A result that may shed a new light on the decline and mass mortalities observed in bee colonies in the United States, France, and in most European countries. For today, according to the ANSES (the French Agency for Food, Environmental and Occupational Health Safety) Imidacloprid residues are found in 50% of France’s hives. And the presence of Nosema Ceranae has proven in almost all of them since at least 2002, as shown by Marie-Pierre Chauzat – from the ANSES.

But until then, as the pesticide industry continues to proclaim, the insecticide alone is not considered lethal at low doses. No more than also Nosema – Marc-Edouard Colin, of Supagro (Montpellier) has already shown in 2006 that Nosema was present in hives that worked perfectly normally.

However, the combination of the two is a time bomb.
