Abstract

Spodoptera frugiperda is one of new invasive pest insect in Indonesia that was initially found in early 2019 in corn field at northern part of Sumatera island. Recently, it has been reported that this pest was already found in some corn field area in Sumatera, including Lampung as well as west part of Java and Sulawesi. As one of the biggest corn producing area in Indonesia, Lampung should be aware of the presence and the spread of this pest. This research was performed to confirm the presence of S. frugiperda in Lampung and investigate the damage including its natural enemies. Observation was conducted during February-April 2019 at four central corn-producing area in Lampung, namely Lampung Selatan, Pringsewu, Lampung Timur and Pesawaran. A purposive random sampling was used in this research. Twenty plants was randomly chosen as sample in every plot. The data collected in this research was species identity, plant damage, and its natural enemies. Identification was performed by morphological and molecular technique. Investigation of its natural enemies was conducted by field observation and collecting larvae as well as egg mass and taken to the laboratory to observe the emergence of the parasites. Based on morphological characteristics and molecular technique it was confirmed that the larvae was S. frugiperda. Plant damage caused by this pest was in the range of 25.60-79.12%. Two kinds of natural enemies found in this study, namely Telenomus sp. as egg parasite and Syrphid fly as the larvae parasite.
