There's no shortage of speculation on the
internet about colony collapse disorder, which is the name given to the
recent decrease in honey bee populations.
I'll share with you two things I've discovered that may or may not be
connected --- you be the judge.
In the May,
1988 Journal of Comparative Physiology, Sensory, Neural, and Behavioral
Physiology a group of German scientist confirmed that
magnetic field bursts at a frequency of 250 Hz induced unequivocal
"jumps" of misdirection in honey bee navigation of up to 10 degrees.
The Ground
Wave Emergency Network (GWEN) is an array of 300 transceivers
distributed across the continental United States with a spacing of
about 250 miles. GWEN was designed to transmit critical warning and
response messages that would be immune to the effects of
electromagnetic pulses, which would be generated by a high altitude
nuclear explosion. The system was supposedly replaced by the Milstar
satellite system, but it seems to me a satellite might be vulnerable
and they might want to keep GWEN on the back burner. The Wikipedia
entry on GWEN proves the system has a wide range of frequencies and
might be capable of producing signals within the 250 Hz range.
Every year we add some kind of new gadgetry to make cell
phones work better and internet's to run faster, all the while
polluting the air with electromagnetic frequencies. It's not such a bad
thing to live in a hilly area that seems to be mostly blocked from cell
phone signals and TV stations. Maybe our bees will avoid this problem
thanks to our unique geography.
