Thanks Alan,! Thanks Vicki!

Yes, Tomatoes are all pollinated this way.  They need to be native bees.  H=
oney bees can't do the sonication, or buzz, pollination.  A very interestin=
g adaptation using a static charge and specific frequencies.  The static ma=
kes the pollen sticks on the bee.

Thank for the other tips on the singing insects.  I will pass this on to th=
e researchers and see if it goes anywhere.
