The mid-winter development, reproduction and survival of field-acclimatized viviparae of Sitobion avenae and Rhopalosiphum padi on leaves of tillering wheatand perennial ryegrass (Lolium perenne) plants at similar growth stages were compared by monitoring batches of aphids in clip-cages in field plots in southern England. For both aphid species, survival, total fecundity and reproductive rate were much higher on wheat than on L. perenne, and on both host-plants they were much higher for S. avenae than for R. padi. Development times (in day-degrees C) were longer on L. perenne than on wheat, and those on both host-plants were longer for R. padi than
