  abstract = {{T}he ability of the congeneric braconid parasitoids {C}otesia sesamiae ({C}ameron) and {C}otesia flavipes {C}ameron to discriminate between stemborer larval cues upon contact was studied using their natural hosts, namely the noctuid {B}usseola fusca ({F}uller) and the crambid {C}hilo partellus ({S}winhoe), respectively, and the pyralid non-host {E}ldana saccharina ({W}alker). {W}hen the natural host larvae were washed in distilled water, parasitoid behavior was similar to that displayed when in contact with {E}. saccharina, characterized by the absence of ovipositor insertion. {W}hen washed host or non-host larvae were bathed with water extracts of their natural host, the parasitoids showed a significant increase in ovipositor insertions. {H}owever, the water extracts of host-larvae deposited on cotton wool balls did not induce ovipositor insertion in either {C}. sesamiae or {C}. flavipes. {N}evertheless, the extracts enabled the parasitoids to discriminate between natural and non-hosts as indicated by the intensive antennating of the former. {F}or both parasitoids, frass was found to be important in short-range host recognition as indicated by differences in the time spent on antennating between frass sources. {I}n addition, the regurgitants of {B}. fusca and {C}. partellus induced ovipositor insertion in {C}. flavipes only. {T}hese results indicated that {C}. sesamiae and {C}. flavipes used different chemical cues for acceptation and oviposition in a stemborer larva, and that {B}. fusca and {C}. partellus shared the same chemical cues to induce oviposition in {C}. flavipes.},
