  abstract = {{S}onchus oleraceus {L}. ({A}steraceae), an annual species native to {E}urasia and northern {A}frica, is among the most widely distributed plant species on {E}arth. {I}n {A}ustralia, {S}. oleraceus, is a common weed in disturbed areas such as crop fields, pastures, gardens and roadsides. {I}n agricultural settings, it can dominate fallows and cultivated fields where it uses stored soil moisture and reduces crop yield. {T}his weed has also developed herbicide resistance, predicating the need for alternative management solutions. {I}n this context, we undertook field surveys and preliminary host range studies in the native range of {S}. oleraceus to determine the feasibility of developing classical biological control solutions for {A}ustralia. {F}ifty-nine phytophagous arthropod species were recorded and nine pathogenic fungi were recovered from disease symptoms. {F}our arthropod species were selected for initial host-specificity testing based on information available in the literature. {P}reliminary host-specificity tests were also performed with representative isolate(s) of six of the pathogenic fungi. {A}ll these candidate agents were shown in the tests to affect key native species in {A}ustralia in the same subtribe as {S}. oleraceus (i.e. {S}onchus hydrophilus and {A}ctites megalocarpus). {T}he results of our investigations suggest that classical biological control may not be a feasible option for the management of {S}. oleraceus in {A}ustralia, and that alternative integrated weed management tactics may need to be pursued to mitigate the impacts of this weed.},
