Neonicotinoids Pesticides

Neonicotinoids Pesticides 

One of the major concerns is the use of pesticides to protect crops from harmful vegetation, fungal diseases and bacteria growth. One of the major pesticides used is neonicotinoids a very popular pesticide used in the United States to promote growth in crops. However this pesticide is a toxin for the bees and has a direct correlation between the use of this pesticide and the resulting death of the honey bees.

There is a direct correlation between the introduction of the neonicotinoids pesticides in the United States and the start to a loss of approximately 50 million pounds of honey produced in the next fourteen years.
The neonicotinoids pesticides do not have an immediate acute death on the honey bees. The way it effects the bees is that it effects the immune system leaving bees and hives more vulnerable to the infestation of deadly diseases such as nosema. The pesticides impairs a lot of the bees key function navigation, food collecting, queen bees production etc. This all leading to the vulnerability of winter to the hives and hence the massive losses that have been seen since winter 2006.

Ontario, Canada has been a case study for the use of pesticides, where movement is starting to occur from beekeepers in the area to ban the pesticides. Beekeepers report that there has been at increase from 15% losses to a large 50% since the increased use of the pesticide.  A beekeeper in Ontario Dave Schuit recorded losses of 600 hives totalling to an approximate amount of 37 million bees dying, “Once the corn started to get planted our bees died by the millions”.

Regulations have been put in place as part of the Plant Protection Product Regulations 2005 a two stage process undergoing two approval stages. EU members in Europe comply with these processes which takes a look at the environmental effects of using particular chemicals in the area of interest. In the case of neonicotinoids the surrounding habitats and how they affect their behaviour and of course mortality rates, Germany have made a conscious effort to protect the bees from these pesticides by banning the substance produced by bayercropscience in 2008. Needless to say there is sufficient evidence that this pesticide has direct links to the mortality rates of bees. Some urgent action needs to be taken to tackle this problem.
