Figure 7From: Density-independent population projection trajectories of chromosome-substituted lines resistant and susceptible to organophosphate insecticides in Drosophila melanogasterA 19 × 19 Leslie matrix, used for calculating density-independent population projection trajectories from a single adult female. Age-specific fecundity, f(x), and survival probabilities, P(x), over 19 days were used to construct a 19 × 19 Leslie matrix for each chromosome-substituted line.Back to article page
