The Y-autosome translocation results in the linkage of Y chromosome and wild-type phenotype because they are heterozygous, one other allele carrying a wild-type allele on their Y-translocated chromosome and the other mutant allele on their free autosome. white pupae ( wp), black pupae ( bp), temperature-sensitive lethal ( tsl) mutations). GSSs have been developed based on a classical genetic approach, which requires a combination of Y-autosome translocation (T(Y A)) and a selectable marker (e.g. The elimination of females lowers the cost of mass rearing and field release.įor tephritid fruit flies, the development of genetic sexing strains (GSSs) is made possible by the separation of the male and female individuals in the mass rearing. The presence of sterile females also distracts the mating between the released sterile males and wild females during SIT application. The release of sterile females is not desirable because ovipositing by pest damages fruits. One way to improve the effectiveness and cut operational costs of the SIT is to release high quality male-only sterile insects. Hence, the reproductive potential of these wild males is reduced. Subsequently, the sterile insects are systematically released to compete against the wild male population. The SIT program involves mass rearing and sterilisation by radiation of a target insect colony in a facility. Pest-free areas can also be developed, maintained and protected by the integration of SIT.
The sterile insect technique (SIT) is a widely accepted pest population suppression method due to its species specificity and environmentally-friendly nature.
