Abstract
Rhinocyllus conicus (Froelich), a weevil introduced into the Gallatin Valley for biocontrol of musk thistle, was found to also infest 3 related species, Canada, bull, and wavy-leaved thistles. High weevil infestations within seed heads, reduced seed production, and reduced seedling density all indicated a strong suppressing effect on the musk thistle population.This publication has 1 reference indexed in Scilit:
