SUMMARY The levels of resistance present in two cereal and four grass hosts of M. f. cerealium were assessed in terms of the percentage of alatae flying from the host and reproductive rates of alatae. Festuca rubra and F. arundinacea exhibited highest levels of resistance, inducing a greater proportion of the alatae to fly (94% and 84% respectively) after producing only a few nymphs. Although between 38% and 64% of alatae flew from L. multiflorum , oats, L. perenne and wheat these alatae deposited more nymphs on the hosts before flight than occurred on Festuca . The weight of alatae did not influence the flight response. The differences in the flight/reproductive response of M. festucae to various host plants are discussed in relation to possible host selection strategies of this species and to antixenotic/antibiotic host resistance experiments in general.
