Figure 2: Cry1Ac Dose-Response Assay.
Dose-response curves for H. zea neonates in diet-incorporated bioassays (Experiment 1). One of the diets was a commercially available (CD) carbohydrate-biased rearing diet commonly used for Bt resistance monitoring. The other two diets were modified (MCD1 and MCD2) to reflect protein-carbohydrate profiles that are more physiologically- and ecologically-relevant and to align with H. zea’s self-selected P:C intake target. Mortality represents the average for three trials; the LC50 concentrations are listed for each diet (N = 22–28 larvae per concentration).
