Abstract
Spodoptera frugiperda (Lepidoptera: Noctuidae) is a pest that boomed in early 2019. The research was conducted descriptively in areas that had never been attacked by S. frugiperda by planting various types of crops such as sweet corn, white corn, hybrid corn, green beans, tomatoes, chilies and sorghum. The results showed that S. frugiperda was very fond of sweet corn, followed by white corn, hybrid corn and sorghum. Green bean, chili and tomato plants were not attacked by S. frugiperda. Pest S. frugiperda began to attack sweet corn plants at 3 weeks after planting with the initial attack in the form of scratches on the leaves and continued to the base / growing point (leaves still curled). Even this pest also attacks the male flowers that have not opened and attacks the sweet corn cobs. S. frugiperda began to attack sweet corn at the age of 20.33 days after planting, on white corn 25.67 days after planting, hybrid corn 25.53 days after planting and sorghum at 28.67 days after planting. In sweet corn, the attack reached the corn cobs, while in white corn and hybrid corn, the attack only showed damage to the leaves, not to the cornflower as well as to sorghum. The percentage of attack on white corn (22.15%) and hybrid corn (18.26%) and on sorghum was only 10.34% less than attack on sweet corn (40.02%).

Summary
Spodoptera frugiperda (Lepidoptera: Noctuidae) merupakan hama yang booming di awal tahun 2019. Penelitian dilakukan secara deskriptif pada areal yang belum pernah diserang S. frugiperda dengan menanam berbagai jenis tanaman seperti Jagung manis, jagung putih, jagung hibrida, kacang hijau, tomat, cabe dan sorghum. Hama S. frugiperda mulai menyerang tanaman jagung manis pada 3 minggu setelah tanam dengan serangan awal berupa goresan pada daun dan berlanjut ke pangkal/titik tumbuh (daun yang masih menggulung). S. frugiperda mulai menyerang tanaman jagung manis ketika berumur 20,33 hari setelah tanam, pada jagung putih 25,67 hst, jagung hibrida 25,53 hst dan sorghum pada umur 28,67 hst. Pada jagung manis serangan sampai pada tongkol jagung, sedangkan pada jagung putih dan jagung hibrida serangan hanya terlihat kerusakan pada daun saja, tidak sampai menyerang bunga jagung demikian juga pada sorghum. Jagung manis merupakan tanaman yang sangat disukai oleh S. frugiperda, diikuti oleh jagung putih, jagung hibrida dan sorhgum, sedangkan kacang hijau, cabe dan tomat tidak disukai oleh S. frugiperda.
