The invention relates to the field of warehouse management, and discloses a stored-grain insect habitat regulation and control system. The regulation and control system comprises an insect condition sensor (1), an in-warehouse temperature and humidity detection device (2), a temperature and humidity regulation device (3) and a control device (4), and is characterized in that the insect condition sensor (1) is used for detecting stored-grain insects; the in-warehouse temperature and humidity detection device (2) is used for detecting the temperature and humidity in a warehouse and/or grain pile; the temperature and humidity regulation device (3) is used for regulating the temperature and humidity in the warehouse and/or grain pile; and the control device (4) is used for judging the species of the insects, controlling the temperature and humidity regulation device (3) to regulate the temperature and humidity in the warehouse and/or grain pile according to a habitat range of the insects to enable the temperature and humidity in the warehouse and/or the grain pile to exceed the temperature and humidity required by the habitat range of the insects so as to control the insects. The regulation and control system can automatically change the warehouse environment in a most economization and environmental protection mode, thereby suppressing the insects, and protecting the safety of the stored grain.
