Biological control of Lilioceris lilii (Scarlet lily beetle)

As far as I am aware, there arent any biological controls that are widespread yet in the northeast.   The wiki link has some promising possibilities but I have never seen a parasitized lily beetle, and they are abundant here in lower NY.  While it may not be registered officially as a control, I find that imidicloprid applied to the shoots shortly after emerging and maybe once more when they are fully grown is the only way to control the lily beetles.   They really do a number on lilies once they find them and hand control is ineffective in my experience (or if one has a lot of lilies).  I fear what they may be doing to our wild lily populations in the northeast, not that there are many wild lilies around here, the deer would also be a problem locally.

Hi guys,

First of all, I would like to thank you for letting me (us) join this so
interesting forum and email exchange!

Do anyone of you have any tips and experiences about biological control of
the Scarlet lily beetle beside the Wiki's informations?

Many thanks,

Louis Richard…
