Since most aeroponics setups are in a controlled environment, the risk diseases and pests are largely eliminated. Of course, in open-air environments pests can attack just like anywhere else, and certain diseases can be carried in on the wind. If diseases are caught early enough, it's possible to handle the situation by removing the individual affected plants, but pests will probably require traditional treatment, whether that's chemical or organic.
In an indoor environment, care should be taken to keep the space clean and relatively sterile. perform regular maintenance to prevent potential problems from taking root includes sterilizing the pump system and the root chamber in between crops. Take care not to accidentally introduce pests or diseases to your aeroponics grow areas by cleaning up organic debris and don't bring plants rooted in soil or organic media in from the outside without a period of quarantine. These common sense measures will keep aeroponics systems remarkably pest and disease free.
