Location: Pastures in Montgomery and Giles
Counties, Virginia.
Objective: To determine the response of musk and
plumeless thistle to the thistle rosette weevil.
Summary: In 1980, two sites were selected, each
heavily infested with musk thistle, and each a
site at which the thistle rosette weevil had
become established. Fifty weevil-infested and 50
non-infested rosettes were sampled from each site.
In 1981, 100 each of the infested and non-infested
musk thistle plants were sampled. In 1982,
rosettes between 10-15 cm in diameter (small) and
