The effects of seeding dates and insecticide application techniques on Russian wheat aphid Diuraphis noxia (Mordvilko) in winter and spring wheat Triticum aestivum was evaluated in 1988-1990.Autumn infestations declined with later seeding at each location.Winter wheat yields in untreated plots were not adversely affected by infestation levels of 18, 27 and 40%.Infestation levels were low at the 1-2 leaf growth stage?this stage is critical for damage to occur in the autumn.Winter wheat seeded in
