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

الملخص EN

Cost/benefit analyses are essential to support management planning and decisions before launching any pest control program.

In particular, applications of the sterile insect technique (SIT) are often prevented by the projected economic burden associated with rearing processes.

This has had a deep impact on the technique development and its use on insects with long larval periods, as often seen in beetles.

Under the assumptions of long adult timespan and multiple mating, we show how to find approximate optimal sterile release policies that minimize costs.

The theoretical framework proposed considers the release of insects by pulses and finds approximate optimal release sizes through stochastic searching.

The scheme is then used to compare simulated release strategies obtained for different pulse schedules and release bounds, providing a platform for evaluating the convenience of increasing sterile male release intensity or extending the period of control.
