Population dynamics. Insect population over time, with no release (black) or release of ‘sterile’ males homozygous for a bisex‐lethal construct (grey lines) at a release ratio of 1 (dotted), 1.193 (dash‐dot), 1.2 (dashed) or 10 (solid) released males maintained in the environment to the number of wild males at equilibrium. The critical release ratio lies between 1.193 : 1 and 2 : 1. This example is a deterministic, continuous‐time model of a density‐regulated Aedes aegypti mosquito population, illustrating the simulated number of adult females (these are the disease vectors). Model and parameter values as in reported in Alphey et al. (2011a).
