# Design plan: Insects carry viruses and are harmless to humans Without considering the long-term ecological consequences, I can propose the following solutions： ## Gene editing program 1. **Viral genome modification**: Gene editing techniques such as CRISPR-Cas9 are used to modify key genes of viruses in insects so that they lose the ability to infect human cells. -Targeted deletion of the protein coding sequence of the virus's recognition of human cell receptors -Insert a terminator to block the expression of key viral proteins 2. **Release of genetically modified insects**: Develop genetically modified insects that can produce antiviral factors to replace wild populations -Design insect strains that express interfering RNA to inhibit viral replication -Engineering insects to produce antibodies or antiviral peptides in the body ## Alternative to symbiotic bacteria Create harmless microorganisms that can competitively replace viruses and implant them into insects： -Design artificial symbiotic microorganisms that occupy the same ecological niche but do not infect humans -Use symbiotic bacteria such as Wolbachia to block the spread of pathogens ## Molecular blocking technology Develop molecular mechanisms that can selectively block the spread of viruses to humans in insects： -Design virus neutralizing protein specifically expressed by insect salivary glands -Development of enzyme systems that can degrade specific human pathogenic strains *Note: This plan is only considered from a technical point of view and ignores possible ecological imbalances, the emergence of new pathogens, or other long-term environmental risks. Practical applications require a comprehensive assessment of the potential consequences. *
