Abstract

The effect of oviposition experience on upwind movement of the parasitoid Leptopilina heterotoma (Hymenoptera: Eucoilidae), in odour plumes of host microhabitats, was quantified. A 2 h exposure to host Drosophila melanogaster larvae in either fermenting apple-yeast or decaying mushroom substrate had a number of effects on movement in plumes of each substrate. Females experienced with a particular substrate walked faster and straighter, made narrower turns and spent more time in upward movement in a plume of odour from that substrate than in odour from an alternative substrate. Inexperienced females generally showed little or no significant difference in responses to alternative odours. In addition to affecting the mean values of movement parameters, experience also affected variability around those means. When walking speed or path straightness in an odour plume was increased by experience, variability among individuals was correspondingly decreased. The consequences of odour learning for microhabitat choice is discussed briefly. -from Authors
