I just found a raspberry crown borer (looks like a yellow jacket) laying eggs on our blackberries.  I don't believe there are any chemical controls for labeled for raspberry crown borer except RU pesticides.  Is there anyone out there that has found a good cultural control in dealing with these grubs?  Also I found some information indicating parasitic nematodes can offer some control.  Anyone used them?
