Abstract
Genetic regulation of insect populations is a powerful system. It is set up based on the integration of regulation of species specific target gene and sexual specified control elements through genetic transformation. The offsprings produced in the system will have normal males bringing female lethal or abnormal genes. With advantages of species specificity, eco-friendliness and high efficiency, genetic regulation technique (GRT) established with the insect sterile technique becomes a better choice for insect population control. So far, GRT has evolved into the new generation called ‘Release of Insect with Dominant Lethal (RIDL) from the primitive radiation caused sterility and succeeded in several insects. In this review, we introduce the history of GRT and related theories and methods, including the specific regulating elements, lethal or defect genes and the transgenic system. Some successful cases, such as mosquitos, silkworm and cotton bollworm are also listed. Finally, we discuss potential problems and the future of GRT.
