Dose response analysis for corn earworm larvae fed (a) Mir1-CP, (b) Bt-CryIIA, and (c) sub-lethal doses of Bt-CryIIA and Mir1-CP.

<p>The y-axis is the relative growth rate (RGR measured as Δmg/(mg_avgd) and vertical bars indicate one standard deviation. The least significant difference (LSD) at the 0.05 confidence level for the RGR values were as follows: Mir1-CP = 0.25, Bt-CryIIA = 0.3, sub-lethal doses of Bt-CryIIA and Mir1-CP = 0.42. Numbers (mean±SD) in the histogram bars are the average percentage mortality for each treatment. The least significant difference (LSD) at the 0.05 confidence level for mortality were as follows: Mir1-CP – 7.4, Bt-CryIIA – 9.5, sub-lethal doses of Bt-CryIIA and Mir1-CP combined – 15.94. Results are based on four independent bioassays. Concentrations are given as parts per million (ppm).
