Abstract

Spodoptera frugiperda with the common name Fall Army Worm (FAW), this pest comes from the United States and invades corn crops throughout the world. In Indonesia, S. frugiperda began to attack maize plantations in West Pasaman, West Sumatra in March 2019, while in South Sulawesi the presence of S. frugiperda was reported to have started attacking maize plantations in July 2019. Yield losses due to S. frugiperda attacks could reach up to 73 %. This study aims to observe the use of resistance varieties resistant to S. frugiperda attack, the parameters observed population and the percentage of attack on maize. The study was carried out in Jeneponto Regency, South Sulawesi in July-September 2020. The study used a Randomized Block Design (RAK) consisting of 4 treatments and the treatment was five times, the type of treatment used A: Corn Varieties NK-7328, Pulut Corn Varieties, Corn Varieties Sweet (Paragon) and BISI-18 Corn Varieties. The parameters observed in this study were the population of S. frugiperda, the percentage of attacks and the population of predators. The results showed that the Sweet Corn (Paragon) variety had the percentage of FAW attacks, the total population of S. frugiperda and the average predator population highest compared to other varieties.
