Hi Karsten,

The folks from Pipfuit New Zealand are very 
interested in the potential to import Heringia 
calcarata (a specialized predator of woolly apple 
aphid in apple orchards here in the mid-Atlantic 
of the USA) to NZ for supplemental biological 
control of the aphid. I have a sabbatical pending 
toward that end from January through April of 
2010 and need to address a number of fundamental 
questions pertaining to that goal in advance of 
the visit. Perhaps the most important of those is 
whether or not we can have Heringia mate in 
captivity. So, the details any of your 
experimental approaches that have or have not 
worked would be of great interest.

Thanks so much for your help.

Cheers - Chris
