Abstract

Interest in Ceuthorhynchidius Horridus (Panzer) has increased in the past decade because of its potential as a biological control agent for Carduus thistles. C. horridus was imported from Europe on the recommendation of Frick (1969), and underwent host specificity tests (Ward et al. 1974, Kok 1975) and basic biology studies (Kok et al. 1975) prior to official approval for its release in Virginia in 1974. Establishment of this weevil (Kok and Trumble 1979), its life history in Virginia (Trumble and Kok 1979), and incorporation of this species into an integrated pest management program for musk thistle (Carduus nutans L.) and plumeless thistle (c. acanthoides) (Trumble and Kok 1980a) have recently been reported.
