Abstract
Since most insect vectors cause indirect injury to crops, the utilization of natural enemies for their control is considered as a promising. A case study was done on an Eulophid parasitoid Tamarixia radiata introduced in Taiwan to control Diaphorina citri, the insect vector of the citrus greening disease. The biological data of T. radiata were collected in the laboratory. Results showed that T. radiata preferred the 5th istar D. citri nymphs as its host. High percentage of parasitism was found on Jasmine orange hedges which had relatively high host density. Pruning hedges adversely affected the parasitism by T. radiata.
