() Native range research assists risk analysis for non- targets in weed biological control: the cautionary tale of the broom seed beetle. Curculionidae are a large mainly herbivorous family of beetles, some of which have become crop pests. Classical biological control has been attempted for about 38 species in 19 genera, and at least moderate success has been achieved in 31 % of cases. Only two weevil species have been considered to be completely controlled by a biological control by: 1.

Dept. of Agriculture, (OCoLC) Material Type: Government publication, National government publication: Document Type: Book: All Authors / Contributors. Carduus is a genus of flowering plants in the aster family, Asteraceae, and the tribe Cynareae, one of two genera considered to be true thistles, the other being Cirsium.

Plants of the genus are known commonly as plumeless thistles. They are native to Eurasia and Africa, and several are known elsewhere as introduced species. This genus is noted for its disproportionately high Family: Asteraceae.

Concern over the economic and environmental effects of invasive species is widespread (see McKnightOTA).Clearly some plant species, when released from limiting factors in their indigenous environments and spread by their interaction with humans, expand to form large, dense, undesirable stands, e.g., Opuntia spp.

Kelly and Popay () estimated the costs of lost pasture production due to thistles (mainly Carduus nutans with some C. pycnocephalus and Cirsium arvense) in a paddock in New Zealand and found that control with herbicide would have been cost-effective in some seasons but not in all, due to the fluctuation in thistle populations.
