One, A. alexanderi, is a generalist and the risks of non-target damage to the native phycitid and pyralid moth faunas of the United States may eventually disqualify biological control of C. cactorum as a viable strategy. However, when biological control agents are introduced outside of their natural range to control invasive plants, there is the potential for unpredictable and irreversible ecological consequences. For example, the Eurasian weevil (Rhinocyllus conicus) was introduced to control musk thistle (Carduus nutans); however, it also feeds on native. The introduction of exotic biological control agents is not an intrinsically safe operation, but one that is made safe by the way it is practiced (McClay and Balciunas ). This is understood by every responsible biological control practitioner, and is reflected in the wording of the HSNO Act, and in the Methodology Order that interprets it.

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. Weed Sci. 24, Dunn, P.

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.

Several insects have been introduced to North America as biological control agents for non-native thistles (Cirsium arvense, Cirsium vulgare, and Carduus nutans (= Carduus thoemeri).The root and stem weevil Hadroplontus litura (= Ceutorhynchus litura) was released in North America in specifically for C.

The. In the United States, the weevil Rhinocyllus conicus contributes to the control of exotic thistles (Carduus spp.) on rangelands, but it also reduces the reproductive success of native thistles (Cirsium spp.) and, consequently, their insect fauna in national parks and nature reserves (Loudaetal.

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.

In this article, we evaluate the evidence for success and risks of classical biological control of weed species using arthropods. Two recent syntheses have addressed the success of biological control of invasive plants (Clewley et al.
