“…The best evidence for pathogen-mediated frequency-dependent selection in plants comes from only one species (Chondrilla) and from other kinds of experiments besides reciprocal transplant experiments (Burdon et al 1981(Burdon et al , 1984Supko et al 1988;Chaboudez and Burdon 1995). Pathogen-mediated frequency-dependent selection is dicult to test because it is an evolutionary process that involves changes in genotype frequencies over time, which is dicult to assess in long-lived species.…”

Reciprocal transplant experiments have been used to estimate the probability that negative frequency-dependent selection by natural enemies has occurred in host populations by determining whether pest populations are less adapted to "foreign" (rare) hosts, which originate from a population with which the pests have not coevolved. However, these experiments usually confound the effects of frequency and origin: the rare genotypes are also genotypes that did not originate at a site. When clonal organisms are used, and the clones occur in more than one population, it is possible to separate the effects of origin and frequency. Here I present the results of an experiment in which Arabis clones of known frequency were reciprocally transplanted among sites. Contrary to expectations, clones at their site of origin had less disease, less herbivory, and higher fitness than foreign clones. However, variation within and among sites in herbivory and infection was large, suggesting that the number of sites and clones needed to thoroughly test the hypothesis of negative frequency-dependent selection in this system is very large: thus, these results are suggestive but not conclusive.

“…The fungus was closely related to skeleton weed, and fi nally the fi rst strain of this fungus was released in Australia, capable of suppressing the skeleton weed (Hasan 1988 ). Puccinia chondrillina also proved to be effective in the control of skeleton weed when released in western USA (Suopkoff et al 1988 ). The other examples of classical biological control agents are smut fungus Entyloma ageratinae imported from Jamaica to control Hamakua pamakani ( Ageratina riparia , Asteraceae family) in Hawaiian forests and rangelands, and Uromycladium tepperianum has been used to control the invasive tree Acacia saligna in South Africa (Morris 1997 ).…”

AbstractAgents for biological control of weeds have been used for more than 100 years. The classical biological control, which is the introduction of adequate natural enemies from the homeland of a weed of foreign origin, often results in successful control of the weed populations. This method is used all over the world and is considered economically effective, efficient and environmentally safe. Long-term programmes for biological control require a very careful approach and management. The present paper overviews the existing programmes for biological control of one of the most invasive and most aggressive weeds -Chondrilla juncea L. (Asteraceae). After many years of research the weed is successfully controlled in Australia and some States of America with a year-round warmer climate. Further research on potential bioagents that could be effective in the States with a cooler climate is being carried out while focusing on the center of origin of the weed treated -the Balkan countries.As a result of a research conducted during 2000-2007, 51 insect species were identified, feeding on the host plant and causing damages on its root system, vegetative and reproductive parts. The moth Schinia cognata Fr. (Lepidoptera: Noctuidae) proved to be of significant scientific interest with regard to the purposes of the biological weed control.Êëþ÷îâè äóìè: Chondrilla juncea, áèîëîãè÷åí êîíòðîë íà ïëåâåëè, áèîàãåíòè.
