Nuclear Technology Aids Pest Control: Sterile Insect Technique Achieves Results in Multiple Countries

The application of nuclear technology is not limited to power generation and heating. In areas such as agricultural pest control, animal health, and disease vector management, the Sterile Insect Technique (SIT) based on cobalt-60 gamma rays is playing an important role. The core approach of SIT involves mass-rearing target pests in specialized facilities, separating males, and then irradiating them with a cobalt-60 gamma ray source. The radiation causes DNA breaks in the reproductive cells of male insects, leaving them able to fly and mate with wild females but unable to produce viable offspring. As large numbers of sterile males are continuously released, the proportion of ineffective matings in the wild population increases, pest numbers decline generation after generation, and under certain conditions...

Chinese Team Proposes "Toxic Blood Meal" Pre-Treatment Approach to Boost Sterile Insect Technique for Mosquitoes

Chinese researchers have recently proposed a novel sex-sorting approach for the Sterile Insect Technique (SIT) in mosquitoes: adding a specific agent to the blood meal ingested by female mosquitoes, leveraging the biological difference that female mosquitoes feed on blood while males do not, to substantially reduce the number of females before release. The study was published in the June issue of the Journal of Medical Entomology. The Sterile Insect Technique is a pest population control method centered on radiation-induced sterility. Its basic process involves mass-rearing male target insects in the laboratory, sterilizing them through radiation exposure to render them reproductively incapable, and then releasing them into the field, where they mate with wild females to produce non-viable eggs, thereby suppressing target population growth. This technique has been incorporated into integrated pest management systems and is regarded as a relatively environmentally friendly pest control approach.
