The Yellow Starthistle Hairy Weevil, Eustenopus villosus, is our best new insect for this poisonous weed. Adult weevils feed externally on the flowers and larvae feed within, destroying seed production. A good disperser, this agent can become widespread and have a significant impact on starthistle seed production. The Yellow Starthistle Hairy Weevil appears to have significant potential as a bio-control agent of yellow starthistle. Releases of 105 adults are $50.00 in July.
