The information above is from daily cankerworm counts for several years in Charlotte NC.

In 2006, I only have the monthly totals. 

If the migration starts early, and January is a big month, then we will have a heavy infestation. IMO

I think that 2009/2010 will be a lite year for most areas around Charlotte.  No promises…….
