In order to clarify the influence of temperature on the parasitism of Habrobracon hebetor (Say), the paralysis and the parasitism of the parasitoid H. hebetor as a biological control agent against Indian meal moth, Plodia interpunctella (Hubner), were determined at 17, 20, 23, 26, 29, 32 and 35[degree]C in the laboratory. The functional response of H. hebetor parasitizing P. interpunctella was examined at different host densities. A functional response equation was fitted to each temperature regime. The results indicated that within the temperature range of 17 to 29[degree]C, the handling time was inversely proportional to temperature, ranged from 0.341 d at 17[degree]C to 0.068 d at 29[degree]C. But over 29[degree]C, the handling time was extended. But over 32[degree]C, the instantaneous search rate decreased as the temperature increased. A temperature mediated functional response equation was fitted to the data, in which the handling time was a quadratic function of temperature. Accordingly, H. hebetor can parasitize more individuals of hosts within the temperature range of 26 to 29[degree]C, which id favorable for its reproduction.
