  abstract = {{S}onchus oleraceus is an annual species native to {E}urasia and {N}orthern {A}frica that has become a major weed of cultivated fields and ruderal areas in {A}ustralia. {P}opulations are difficult to manage in cropping systems because of the development of resistance to common herbicides. {B}iological control is being investigated as an additional tactic for managing the weed. {A} literature review was conducted to identify the phytophagous arthropod species already associated with the species in {A}ustralia to guide such a biological control programme. {T}o identify opportunities for biological control agents to aid in management, we undertook field surveys across {Q}ueensland and {S}outh {A}ustralia in different environments. {W}e also investigated factors that may influence their performance in {A}ustralia. {B}oth the literature review and field surveys identified 21 arthropod species associated with {S}. oleraceus in {A}ustralia, most of them being generalist species and pests of exotic origin. {C}apitula were the most damaged plant part while stems were relatively free from insects, except aphids. {T}he field surveys recorded an unexpected new interaction between {S}. oleraceus and the gall midge, {C}ontarinia jongi ({D}iptera: {C}ecidomyiidae). {T}his association was surprising as the midge, only known to develop on {A}lstroemeria ({L}iliales: {A}lstroemeriaceae), a very distant relative to {S}. oleraceus ({A}sterales: {A}steraceae), was reported in {A}ustralia only a few years ago under greenhouse conditions. {T}he midge and the moth {E}ublemma cochylioides ({L}epidoptera: {E}rebidae) were the two species that occurred most frequently in developing flower head samples. {W}e considered their infestation rate as a proxy of herbivory and tested whether the environment surrounding the plant may influence herbivory. {B}oth {E}. cochylioides and {C}. jongi showed the highest infestations in ruderal sites compared with the sites located in conventional farming areas. {W}e discuss the implications of our results in the context of selecting and releasing candidates for the biological control of the weed, especially in agricultural landscapes.},
