The functional response ofCyrtorhinus lividipennis Reuter attacking the brown planthopper(Nilaparvata lugens (Stål.), BPH) eggs on rice was determined at six constant temperatures of 20°C, 23°C, 26°C, 29°C, 32°C and 35°C. Rogers’ (1972) random predator equations were fitted to the data for each temperature separately. The equation model adequately described a Holling’s Type II functional response forC. lividipennis and produced biologically realistic estimates of attack rates and handling times at five experimental temperatures between 20°C and 32°C. However, at 35°C, a negative handling time(Th = - 0.0029) was produced. The effect of temperature was incorporated in to Rogers’ equation by making the attack rate(a) and handling time(Th) functions of temperature within the range 20°C to 32°C. The attack rate and handling time were fitted as hyperbola and reciprocal hyperbola functions of temperature respectively. The temperature incorporating fourparameter composite model fitted the combined data as well as did separate Rogers’ equations based on the parameter estimates.
