Setothosea asigna is one of the important pests that attack oil palm plants and can cause economic losses. The purpose of this survey was to identify the symptoms of Setothosea Asigna attack and how to control it on oil palm plantations. The method used is by using the survey method, namely collecting data or information by taking direct samples at random. From the results of observations in the field, the results of the symptoms of the attack are clear. On the leaves observed, it is very visible leaves like burning. On the leaf blade there is an elongated hole. It is very clear that the impact that occurs on the leaves is that the strands are eroded from the bottom of the leaf to the top and this makes the leaves only leave the bones. In general, leaves that are attacked by Setothosea asigna are leaves that are getting old. As a result, oil palm plants cannot photosynthesize properly and the production of bunches is not optimal. In order to maximize the production of oil palm bunches, it is necessary to do intensive prevention and control of pests that attack oil palm plants, one of which is the caterpillar (Setothosea Asigna).
