Dear Pankaj,
The shipment of zygogramma bicolorata was held in quarantine for host-specificity test (40 plant species only) before field releases in 1983. (Jayannth, K.P. and Sudha Nagarkatti, 1987, Investigations on the host-specificity and damage potential of zygogramma bicolorata Pallister introduced into India for the biological control of Parthenium hysterophorus. Entomon 12(2):141-145 ).

Thanks Dr.Gautam for the information.
Please quote the source of information about forty test species. I
feel that it is very less number as Zygogramma tested on forty
species has been released in nature having thousands of plant and
insect species of economical value. Why researchers have not tested
it on as much as possible species?

quarantine conditions was done on 40 plant species. Out these, no
adult feeding oviposition or larval feeding were observed except on
Parthenium hysterophorus. Slight adult feeding was observed on niger
(Guizotia abyssinica) and jasmine (Jasminum grandiflorum). Hope,
other experts will also be responding. In case Australian position
remains unattnded, let me know I will get back to you after recovery
from my ill health in order to reply this part.
