Impact On Honeybee Navigation
In the latest research published by the team of Dr. Randolf Menzel, Dr. Johannes Fischer, Dr. Teresa Müller, Dr. Anne-Kathrin Spatz, Dr. Uwe Greggers, and Dr. Bernd Grünewald, titled, Neonicotinoids Interfere with Specific Components of Navigation in Honeybees,the impact of three neonicotinoids was tested to see the effects on honeybee navigation.
The neonicotinoids: imidacloprid, clothianidin and thiacloprid were selected because of how they directly work on the brain and change the function of the brain. The chemicals were applied at non-lethal doses in order to test their effects on honeybee navigation.

The Complexity Of The Honeybee Brain
Most people think of a honeybee as a simple insect. However, they are social beings that communicate in multiple ways. The Honeybee, Apis mellifera has been studied extensively with respect to its sensory and neural capacities in navigation, communication, visual and olfactory learning and memory processing. The Virtual Brain Project was formerly funded by the BMBF as a subproject of the Virtual Neuro Lab and is now continued in the Project DigiNeuro.

Learn About The Virtual Atlas of the Honeybee Brain
The goal of this project serves to integrate the entirety of information into a Virtual Atlas of the Honeybee Brain. This common spatial reference map will potentiate the representation of structural and functional data obtained in different experiments and from different individuals. Pictured above is the Virtual Honeybee Standard Brain Atlas which is an interactive three-dimensional surface model with integrated neuron and neuronal tracts.

Learn About The Brilliant Mind of Dr. Randolf Menzel:
Dr. Randolf Menzel pioneered the honeybee as a model system in neuroscience with respect to color vision, olfaction, learning, and memory.
Dr. Randolf Menzel
Combining levels of analysis from natural behavior to single neurons, he traced perceptual and cognitive capacities to their neural and cellular substrates. He established the first evidence for the role of the insect mushroom body in memory formation and characterized the cellular and neural correlates of different phases of memory.
We are in Ontarion and have had devastating deaths in our operation.
Thank you for sharing the interview!
Don’t know if this makes any difference. We live in Climax NY. I have s couple car tents that we used to live with Yellow jackets and Bumble bees that we have always had to co-exist as I needed parts from the tents for things and we just had to live together. That was the past, this past summer there were no Bees! No Yellow jackets, no Honey bees, all I seen were 2 sand wasps and 3 honey bees in 2015, no other bees, no bees in any car tents. Ya know after spending many years with them, you just expect them and go through the process of co-existing with them. Where are they?

Frankly, I don’t have the foggiest idea how you figure out how to do great work each and every time. Done! ??????????????
