Abstract

The orientational responses of 4th instar larvae of Chilo partellus to different sources of stimuli being artificial diet, leaves and stems of maize and sorghum were tested, under free choice and no-choice situations. Larvae were attracted to maize and sorghum in a moderate to high degree dependent on what choice they were given. The orientational preference of the larvae, offered a choice between the visual and the odour sources, depended upon their stimulating capacities which were represented by the percentages of individuals responding to the sources of stimuli. Odour played a greater role than visual stimuli in this close range attraction when the two competed with each other.
