I watched a video on a course Mel Disselkoen taught on queen rearing. In that video he takes a significant moment to address his theory on soy and or corn dust being a cause of CCD.
I am interested in finding out what others think on this theory.
In a nut shell Mel seems fairly well convinced that this dust is fatal to bees and has observed an increased loss of hives in relation to them being located near corn or soy fields during harvest. He compares this hazard to his initial practice of dusting larva with flower in order to selectively kill them as his earlier queen breeding program taught. in a similar manner he suspects the dust is lethal to adult bees. Those that survive the fields return with this dust which in turn may be lethal to larva in the hive. He makes some mention that soy dust is outright toxic and this is fairly well known.
Okay that is the nut shell of his theory as I understood it. Mainly I am interested in a more rounded collection of thoughts on this.
