Fig. 6

The over-flooding rates (the number of OX5382G male moths per wild male fall armyworm moth) of OX5382G necessary in computer simulations to delay the accumulation of insecticidal protein (Bt) resistance alleles (A, B, and C) and to suppress fall armyworm population (D and E) when either one or two Bt-producing genes are present in the host corn, and 10% of the field are non-Bt refuge plants. In plots A, B, and C, the horizontal dashed line marks the point at which the resistance allele frequency surpasses 0.5. In plot D, the ‘5’ over-flooding rate line cannot be seen because it is nearly colinear with the ‘10’ over-flooding rate line, and in plot B and E, the ‘0.5’ over-flooding rate line cannot be seen because it is nearly colinear with the ‘1’ over-flooding rate line
