Intervention effect Aphid density and infestation timing significantly influenced wheat yield.
Intervention effect Mid-season S. graminum infestations caused the greatest wheat losses.
Intervention effect Late-season S. avenae infestations caused the greatest wheat losses.
Observation In 2023–2024, S. graminum had its lowest EIL in mid infestations, at 4.886 aphids/feddan.
Observation In 2024–2025, S. graminum had its lowest EIL in mid infestation, at 0.46 aphids/kg.
