Conteúdo: | The objective of this study was to establish whether there are olfactory interactions in the Lysiphlebus testaceipes, Toxoptera citricida and Citrus aurantium tritrophic system. The response of male and female L.testaceipes to different odour sources of the host plant C. aurantium, the aphid host T. citricida and aphidplant complex were investigated using a Y-tube olfactometer. Laboratory experiments were conducted by exposing individually aged male and female L. testaceipes to eight different odour treatments. Response of the parasitoids was taken after 15 min exposure to the volatiles from the different odour sources and based on their orientation to the particular chamber. Seventy percent of both male and female L. testaceipes showed high attractivity to aphid infested leaves. There was no significant difference based on age and sex of the parasitoid on their choice of odour. The organic compounds released by these combinations acted as semiochemicals in the tritrophic interactions and it is suggested that insect feeding induced attraction of the parasitoid L. testaceipes.
