- Corn Z mays L. is one of the agricultural products that has a strategic value in fulfilling food self-sufficiency. Corn is used as an alternative staple and a source of raw materials for making renewable bioenergy. Recently, Spodoptera frugiperda attacks on maize plantations in the highlands and in the lowlands are quite high. Almost all corn plantations are attacked by these pests. Information about the level of attack by these pest on corn plantations is not yet available. The S. frugiperda attack was thought to be closely related to the presence of their natural enemies. Therefore information will be sought regarding the extent of damage to maize plants caused by S. frugiperda and its natural enemies from various stages of the pest insect life-cycle. To find out the level of S. frugiperda attack on maize plantations at various altitudes from sea level areas that cultivate corn plants and to know the natural enemy species. This research was carried out on maize plantations in the lowlands and highlands in Ogan Ilir Regency and in Pagar Alam Regency. In the fields of various stages, several groups of morphological egg, larvae, pupae and imago S. frugiperda were encountered during the survey of maize fields in the lowlands and in the highlands. The survey results concluded that the percentage level and intensity of S. frugiperda pest attacks on maize in the lowlands were higher than in the highlands.
