Transgenic approaches applied to the sterile insect technique of codling moth control
The sterile insect technique (SIT) is a relatively new approach to controlling the codling moth. Compared with the traditional irradiation method, the application of transgenic techniques is much better at producing sterile males. In addition to manual control of developmental conditions this involves using plasmid vectors based on the piggyBac transposon, inserting a dominant conditional lethal gene to culture genetic sexing strains and inserting marker genes such as fluorescent proteins to elucidate the efficacy of gene transfer.
