Review: Genetic Improvements to the Sterile Insect Technique for Agricultural Pests

The sterile insect technique (SIT) relies on area-wide mass-releases of sterile male pest insects, which mate with their wild counterparts and thereby cause a drop in the wild population. In order to improve SIT efficacy or to avoid potential negative effects of such releases, strains of insects hav...

Summary:The sterile insect technique (SIT) relies on area-wide mass-releases of sterile male pest insects, which mate with their wild counterparts and thereby cause a drop in the wild population. In order to improve SIT efficacy or to avoid potential negative effects of such releases, strains of insects have been developed by genetic means. Methods of strain improvement fall into two categories: those generated by classical genetics and those through transgenesis. Here, we describe development and successes of agriculturally important pest insect strains developed through the former, and how transgenic technology is offering a broad spectrum of potential improvements to SIT in a wider range of insects. Also discussed are future prospects and non-technical challenges faced by transgenic technology. The need for environment-friendly pest control methods in agriculture has never been more pressing. SIT and related technologies offer a solution with proven effectiveness.
