The present invention relates to an insect pest control apparatus capable of effectively conducting biological pest control for a large-scale crop storage facility by using a biological control agent. More specifically, the apparatus is capable of periodically and continuously controlling the spreading amount, spreading period, and spreading interval for a predetermined period by controlling the period, in which a natural enemy is hatched into an imago, through a raising part which is able to raise eggs, larvae, and pupae of the natural enemy separately. Moreover, the apparatus is capable of protecting the natural enemy from an external physical environment without a significant influence on the fatality and feed explorability of the natural enemy during the periods from raising to spreading by using a spreading part which is able to be opened or closed. As such, the present invention is capable of increasing the efficiency of pest control and reducing general expenses such as expenses for a natural enemy loss and spreading.;COPYRIGHT KIPO 2018
