Varroa out of control - what pesticides got to do with it

http://www.immenfreunde.de/docs/PKB_engl.pdf

Put down a summary of what I think is the trouble with pesticides and bees.

Brilliant work, Bernhard - a clear summary.
Thank you.

Nice. I placed it on my blog into the Links section. Well worth propagating.

Brilliant Bernhard.

I will share this with others...

Thank you.

Please see this link - do neonicotinoids somehow 'assist' Varroa mite? - I actually think they probably do!

Info about neonics and farmland wildlife in the UK. And usage of neonics in the UK.

If that is true, there are lots of implications.

Sublethal doses of imidacloprid decreased size of hypopharyngeal glands and respiratory rythm of honeybees in vivo

In order to create warmth carbohydrates and oxygen are needed. Thus a disorder of the respiration means a disorder of the heat balance of the Bien. What are the consequences?

Winter loss?

F.....n pesticides! Big time to fight back this ignorant system we live in!

Presentation at the 2013 American Beekeeping Federation by Dr Jim Frazier of Penn State:
We are focusing on synergistic and sublethal effects of multiple pesticides on the chemical senses and chemically mediated behaviors of honeybees in relation to honeybee health and CCD in collaboration with Chris Mullin and Maryann Frazier. Graduate student Daniel Schmehl is also looking at a comparative approach with the solitary bee, Osmia cornifrons.

This study went over three years:

On a German beekeeper and scientist convention the following has been presented. Some studies on neonics and varroa. Findings:

Insecticides affect the population dynamics of mites!
Insecticides cause stress!
Significant effects in the fall if varroa + pesticides
varroa load is higher in the A and B group (which was fed with sublethal doses of neonics
Feeding of neonicotinoids leads to the reduction of hemocytes.
Neonics affect wound closure (wound may not heal well).
For thiacloprid this effect occurs only after high doses. For Clothianidin the effects occur after low doses

How does it effect the varroa population? I wonder if varroa gets more virulent thanks to the pesticides?

There is so much proof that pesticides and mono crop agriculture are causing bee decline yet our overpaid politicians do nothing!

In Denmark they will by 2020 protect 20.000 hectares but I doubt they will do so in my locality.

Here in UK Che, politicians are worse than doing nothing but have given farmers a derogation allowing them to use neonics on Oil Seed Rape despite record harvests last year when they were not allowed to use it!

The fact is here in the UK. government is in the pockets of big business and agri chemical profits are HUGE, so they will always do what they are told by the money men who own those businesses.

Are the big energy companies bleeding you dry?
