Abstract: The results showed that the most preferred host-stage of E. longipes was the 3rd instar of A. takabashi. The parasitization rate of E. longipes was significantly affected by temperature, valuing 4.8% at 18°C, 27.3% at 23°C, and 55.1% at 33°C, respectively. The whitefly immature stages and the parasitoid vertically selected all the layers of jasmine plant as their feeding niches, but the whitefly nymph preferred to gather on the top layer, which was considered as its suitable feeding niche, while the parasitoid selected the middle layer as its feeding niche. To measure the ability to utilize spatial resources, the feeding niche breadth was introduced to demonstrate that the parasitoid had the less wide feeding niche breadth among the all stages tested on jasmine; which revealed that the spatial activity for the parasitoid was smaller than that for any stage of the whitefly. The cluster analysis showed that the feeding niche of the parasitoid was more closely related to the 3rd instar than to any other stage of the whitefly. It was suggested that relation between the whitefly and its parasitoid was not only depending on the host-stage preference but also on the feeding niche similarity.
