Re: Light Brown Apple Moth

Here in California they are unlikely to be held in
check by their natural predators (since those species
don't likely live here), and if the LBAM is active
during certain times of certain temperature ranges,
the possibility exists that in our milder coastal
regions they would remain active for much longer than
in habitat. 
There's no telling how an exotic species will perform
out of its natural context.
