gypsy moth origin

[Teri T]

Potterkat--I've been hunting for the same information.  How odd....Since
I've found that they came into New Jersey in 1911 in an infested
shipment of plants.  Unfortunately, I need to know about their arrival
in contaminated plants that came to Massachusetts in that same year.  Is
there anyone out there who can give us an answer?
