Other claims from this paper (8)

Intervention effect R. padi feeding at 600 aphid-days at the boot stage caused a 19% grain yield loss.
Intervention effect R. padi feeding at 1,200 aphid-days at the boot stage caused a 31% grain yield loss.
Intervention effect Aphid feeding at 300 aphid-days during the anthesis stage caused a 14% yield loss in spring wheat.
Intervention effect Aphid feeding at 600 aphid-days during the anthesis stage caused a 15% yield loss in spring wheat.
Intervention effect Aphid feeding at 1,200 aphid-days during the anthesis stage caused a 20% yield loss in spring wheat.
Intervention effect Regression showed that only R. padi feeding caused a significant yield loss of spring wheat, and only during the boot stage.
Association Reduced spikelet number per head during the boot stage was a principal component of cereal aphid yield loss in wheat.
Association Reduced average seed weight during later growth stages was a principal component of cereal aphid yield loss in wheat.
