The University or Rhode Island Entomology Department has developed and
distributed a wasp which lays its eggs in the larvae (which do the most
damage) of the Red Lily Leaf Beetle and parasitizes them. AFAIK, these
have only been released in Rhode Island and Eastern Massachusetts. It will
take some years for these to be more generally distributed.

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
