Population dynamics of the citrus leaf‐miner (CLM) Phyllocnistis citrella Stainton, and its major parasitoid Citrostichus phyllocnistoides (Narayanan) were investigated from June to September 1994 at the teaching and research farm of the Fujian Agricultural and Forestry University (FAFU), south‐east China. Based on the field investigation, the functional and numerical responses of C. phyllocnistoides were studied in laboratory experiments. During the survey period, four peaks of CLM and C. phyllocnistoides populations were observed in the growing stage of summer shoots and two peaks of CLM and C. phyllocnistoides populations, respectively, in the growing stage of fall shoots. C. phyllocnistoides is the most abundant parasitoid both in seasonal and spatial dynamics, and demonstrates a Holling type III functional response to CLM. Parasitism varied with the densities of both parasitoid and host. A 1 : 10 ratio was recorded to be an optimal proportion of C. phyllocnistoides to CLM.
