Nosema -The Deadly Pathogen fungus that kills bees
Until not long time ago we thought that pesticides were the main cause of the mass death of bees in Spain. The report Nosema ceranae, the murderer that kills bees and this thesis presents a pathogen as the main cause of this ecological disaster. But how does it work? How can we avoid it?
The discoverers of this fungus from Spanish scientists give us more information.
Nosema ceranae was first described in 1996 and was identified as a disease of Apis mellifera in 2004 in Taiwan (Huang et al, 2007; submitted in 2005 but published in 2007).
Nosema ceranae is a relentless killing machine for bees, able to kill an entire colony in just six months. It is a fungus that comes from Asia and was first detected in Europe in 2005 by Mariano Higes, Agricultural Research Center of Marchamalo.
Once the pathogen contacts Bee massively invades their cells, destroys their digestive system.
The fungus affects adult bees, which are responsible for collecting pollen. These bees get sick and do not get back to the hive.
Nosema ceranae is everywhere. Climate change and changes in the agricultural environment aimed to monoculture, will facilitate the expansion.
