The functional response of female Cotesia marginiventris (Cresson) was determined for 5 host densities of fall armyworm at two temperatures. The effect of meridic diets containing a susceptible or resistant corn genotype on functional response was also evaluated. C. marginiventris females exhibited a Type-2 functional response at both temperatures. There was no significant (P over 0.05) difference in rates of parasitism between fall armyworm reared on meridic diet containing a resistant corn genotype versus those reared on diet containing a susceptible genotype
