Rice stem borer causes major damage to rice plants during its infancy, resulting in decreased quality production of rice and crop failure. Yellow stem borer Scipophaga incertulas Walker is a type of rice stem borer that attacks rice plants. To prevent the decreasing quality production of rice and crop failure, the growth rate of rice stem borer must be controlled. In this research, the control is carried out by utilizing its natural predators by using egg parasitoid of the Telenomus rowani Gahan. Therefore, it is necessary to study based on the Mathematical Model to represent the spread of pests so that control can be carried out. From the mathematical Model, it is obtained that the critical point is free from pests and endemic attacks by pests. The stability of the model is analyzed by using the Jacobian Matrix at the critical point. The stability is guaranteed by the existence of the critical point, that is, the egg laying rate parameter of the moth subpopulation. The simulation at the critical point shows that the existence of egg parasitoid can reduce the growth rate and spread of the yellow rice stem borer so that it can reduce the number of rice populations attacked by pests.
