The sterile insect technique is protected from evolution of mate discrimination.

ABSTRACT:

Background

The sterile insect technique (SIT) has been used to suppress and even extinguish pest insect populations. The method involves releasing artificially reared insects (usually males) that, when mating with wild individuals, sterilize the broods. If administered on a large enough scale, the sterility can collapse the population. Precedents from other forms of population suppression, especially chemicals, raise the possibility of resistance evolving against the SIT. Here, we consider resistance in the form of evolution of female discrimination to avoid mating with sterile males. Is resistance evolution expected?

Methods

We offer mathematical models to consider the dynamics of this process. Most of our models assume a constant-release protocol, in which the same density
