PARASITISM OF RHINOCYLLUS CONICUS FROELICH (COLEOPTERA: CURCULIONIDAE) IN WYOMING
AbstractRhinocyllus conicus Froelich was introduced into Wyoming in 1975 for the biological control of musk thistle, Carduus nutans L. A survey of 15 release sites was conducted in 1986 to determine parasitism of R. conicus. Eight species of parasitic Hymenoptera were identified. Parasitism of R. conicus infecting the flower heads of musk thistle was low (0.6%), but greater for weevils within the peduncles (17%). Parasitism varied among release sites, ranging from 0.0 to 1.3%, but was not significantly correlated with the duration of weevil establishment.
