Not sure why you think there was a Cicada invasion in the Midwest in 2004. I
did not see it here near Chicago. As far as I know, the most common cycles in
North America are 17 years for the Northern Cicadas and 13 year cycles for the
Sourthern Cicadas.
I'm still confused about whether the Cicadas crawl up the tree trunks to do
their
damage, or fly up to the branches for the same purpose. I think the Nymphs
crawl
out of their holes and up the trees to lay the eggs. Is that the source of the
tree
damage and if you prevent them from crawling up the trunk, would that stem the
damage?

Here in the Midwest, we expect the 17 year Cicadas to appear around
Mid-May and extend to mid June. They like young fruit trees for
laying their eggs by slitting the bark. They can severly weaken a
tree and leave it open for infection. Larger trees may not be
bothered by them. The solutions I have seen are mostly recommending
covering the young trees with a fabric cloth or possibly using
Surround. I don't like either of these two ideas, so if someone
knows of a better solution, please let me know.

Here in the Ohio Valley we had our Cicada invasion back in 2004. For
young trees the solution of covering the trees with a light fabric
cloth is the best solution I found. Neighbors who did not cover their
young trees did have a lot more damage and it took several years for
the trees to recover (but no one that I know of lost a tree).
By the way, I do have some information on my web site,
http://members.iglou.com/brosen/cicada1.htm along with three dozen
pictures of our 2004 invasion.
Why would the mid-west have a different cicada cycle? By the way, I'm
considered to be in the mid-west and we had it here in 2004, too, so I'm
really confused now.
