  abstract = {{M}aize fields in {A}frica are usually surrounded by land occupied by wild plants many of which harbor lepidopteran stemborer species not found on crops. {I}t is not known if the exotic braconid parasitoid {C}otesia flavipes, which was released in {K}enya in 1993 against the invasive crambid {C}hilo partellus, searches for and attacks these borers in their natural habitats and whether they are suitable for parasitoid development. {T}he objective of this study was to assess the relationship between acceptance and suitability of six stemborer species attacking cultivated sorghum ({C} partellus, {B}usseola fusca, {S}esamia calamistis, and {S}. nonagrioides) or {N}apier grass ({B}usseola phaia and {S}ciomesa piscator) to {C} flavipes. {A}lthough all stemborer species were equally accepted for ovipositor probing by {C} flavipes, only {C} partellus and {S}. calamistis were suitable and produced parasitoids. {I}n olfactometric bioassays, {C} flavipes females were more attracted to stemborer-infested than uninfested plants. {A}nalyses of the volatile compounds showed that they produced richer volatile profiles, mainly comprising {C}5-{C}6 alcohols, terpenoids, aromatic and aliphatic compounds, than uninfested plants. {I}t can be concluded that stemborer species, that were accepted for oviposition but were unsuitable for parasitoid development, form a reproductive sink and that the exotic parasitoid would not establish in areas where these are the predominant species.},
