IPRNG : Message: Zygogramma was tested on how many plant species?

Dear Group Members,
Yesterday I was delivering lecture on Parthenium among school boys.
During discussion on biocontrol I got question about the number of
plant species on which Zygogramma beetles were tested before release in
Australia and India. Experts like Dr. Mahadevappa, Dr.Gautam and
Dr.Throp are with us in this group.

Looking forward for replies.

regards
Pankaj Oudhia
