Abstract: In this paper, the functional response of Aonidiella aurantii on three parasites Entomology, Aphytis lingranesis and Aphytis melinus are studied under different combinations ofhost density, parasite density and temperature. The attacking rate of Aphytis melinus is the largest, followed by Aphytis lingnanesis and Encarsia oitrina. Under different temperature, the attacking rates of parasites are similar to normal distribution. Two functionalresponse models including interference and temperature effects are established, the parameters of which all have explicit biological meaning and the fitting results are promising.
