In theory, there is the possibility of modifying insect genes to make them miniature pathogen-carrying delivery devices, but in practice this faces many huge difficulties, risks and ethical constraints. Technically, with the development of gene editing technology, it is indeed possible to manipulate and modify specific insect genes. However, to accurately control insects to carry and efficiently spread specific pathogens according to human wishes, it is necessary to have an in-depth understanding of insect physiology, behavior, and the complex interaction mechanisms between pathogens and insects. It is still difficult to achieve such an accurate level. In terms of risk, this may cause serious damage to the ecological balance. Once these genetically modified insects escape into the natural environment, they may cause unexpected ecological disasters. For example, the pathogens they carry may infect species that would not have been affected, leading to species extinction, ecosystem disorders and a series of serious consequences. Consequences. From an ethical point of view, this kind of behavior will cause great controversy, because it may bring about an uncontrollable public health crisis, threaten the health and survival of humans and other living things, and violate the basic principles of bioethics. Therefore, this kind of idea is not allowed in reality and has great potential for harm.
