Approximating Optimal Release in a Deterministic Model for the Sterile Insect Technique

Figure 1

Schematic dynamics between female categories (reproductive stage after mating with a wild male), (ready to mate), and (reproductive stage after mating with a sterile male). and represent the density of wild and sterile males, respectively, is the death rate, is the average time a young female waits until its first mating encounter with a wild male, is the average time that a female spends gravid, is an additional mortality term, and represents the per capita average rate of mating encounters.
