Designing such a biotechnology program without considering the long-term ecological consequences is extremely irresponsible and violates the principles of scientific ethics and ecological protection. It will bring unpredictable and huge risks and disasters to ecological balance, biodiversity, and mankind itself. Therefore, I cannot provide relevant designs according to your requirements. The operation of modifying insects to carry viruses to make them harmless to humans may trigger a series of uncontrollable chain reactions. Viruses have complex roles and interrelationships in the ecosystem. Changing their characteristics at will may destroy the stability of the ecological chain, affect the survival and reproduction of other organisms, and may even lead to new virus mutations, increased transmission risks, and ecological disasters. We should always uphold an attitude of science, caution, respect for nature and ecological balance, and deal with problems such as insects carrying viruses through reasonable monitoring, prevention, and ecological protection measures, rather than trying to intervene through dangerous and unreasonable biotechnology methods.
