Summary of model, data transformations, fixed effects, parameters and coefficients of response variables comparing trends in ear damage and infestations of Helicoverpa zea in Cry1A.105+Cry2Ab2 Bt and nonBt sweet corn hybrids during 2010–2016 in Maryland.
The negative coefficient estimates for the interaction parameter (Year: TreatmentNon-Bt) indicates that the rate of changes (damage, consumption, instar growth and late instar proportion) over the past 7 years was lesser for non-Bt than Bt varieties.
