  abstract = {{T}he host recognition and acceptance behaviour of two braconid larval parasitoids ({C}otesia sesamiae and {C}. flavipes) were studied using natural stemborer hosts (i.e., the noctuid {B}usseola fusca for {C}. sesamiae, and the crambid {C}hilo partellus for {C}. flavipes) and a non-host (the pyralid {E}ldana saccharina). {A} single larva was introduced into an arena together with a female parasitoid and the behaviour of the wasp recorded until it either stung the larva or for a maximum of 5 min if it did not sting the larva. {T}here was a clear hierarchy of behavioural steps, which was similar for both parasitoid species. {I}n the presence of suitable host larvae, after a latency period of 16-17 s, the wasp walked rapidly drumming the surface with its antennae until it located the larva. {A}fter location and antennal examination of the host, which lasted 60-70 s and 30 s, respectively, the parasitoid inserted its ovipositor. {S}tinging that resulted in successful oviposition usually lasted 5-6 s. {I}n the presence of non-host larvae, the latency period was between 25-70 s, and parasitoids spent significantly more time walking and antennal drumming on larvae without ovipositing. {I}t is likely that these two parasitoid species use their antennae for host recognition, and both their antennae and tarsi for final acceptance of a host for oviposition. {I}n both {C}. sesamiae and {C}. flavipes tactile and contact-chemoreception stimuli from the hosts seemed to play a major role in the decision to oviposit.},
