Below is a link to a University of Nebraska fact sheet on Musk Thistle (includes information about thistle head and rosette weevil as biological control). This fact sheet mentions that the thistle head and rosette weevils as well as the tortoise beetle have been used in Nebraska. It also mentions that the thistle head weevil is the only species that has been firmly established across Nebraska.
I would recommend that your friend contact one of the authors on this fact sheet. There may be a location in Nebraska with an established population of rosette weevils, etc. where he could make collection. In terms of timing, etc., a population from Nebraska would likely be more successful than a population from Arkansas.
I have not found a commercial source that rears either of these weevils.

I hope this helps.
Below is a link to the Musk thistle fact sheet (with information on the flower head and rosette weevils). The latest revision has not been posted. However, the 2001 fact sheet is still accurate and should be helpful to your friend in Nebraska.

I'll let you know if I find a commercial source for weevils.
