This study used a survey method with purposive sampling, to determine the location of maize plantations that were attacked by S. frugiperda. Furthermore, in the field, the symptoms of attack were observed and the incidence of attacks was calculated based on the presence or absence of attack symptoms, and calculated the level intensity of S. frugiperda pest attack.
