First record of fall armyworm (Spodoptera frugiperda) in Indonesia and its occurence in three provinces

Abstract

The occurrence of a new invasive pest species of corn, the fall armyworms Spodoptera frugiperda (Lepidoptera: Noctuidae) in Indonesia is reported. Survey in 3 provinces in Indonesia: West Sumatera, Banten and West Java were conducted from March to June 2019. The first record of this pest was in 26 March 2019 in West Sumatera. Larvae were collected from each of those locations and field symptoms of damage on corn in the field were observed. Larvae were brought to and reared individually in Insect Biosystematics Laboratory of Plant Protection Department, Faculty of Agriculture, IPB University. Identification of fall armyworm employed morphological and molecular analysis. Identification of the larva based on morphological characters of larvae from 3 provinces confirmed the identity of the pest. The pest as fall armyworms, while the molecular analysis indicated that Banten samples belonged to the ‘rice strain’. Collected larvae from Banten were infected by Metarhizium rileyi. The infested plants in the field showed the typical damage symptoms caused by the fall armyworm.

Biostatistics of fall armyworm Spodoptera frugiperda in maize plants in Bogor, West Java, Indonesia

“…The insect used in this observation was confirmed as S. frugiperda from the characteristics of S. frugiperda larva. The larva has a line on the head forming Y letter and there are dots on the last segment abdomen which form a thick and trapezoidal rectangle (Figure 3) correspond to Sartiami et al (2020). The eggs laid by S. frugiperda in group like pearls covered with scales gave moldy appearance.…”

“…FAW is reportedly found in almost all maize production centers in Indonesia in 2020. FAW collected from Banten confirmed classified Rice Strain after molecular identification using phylogenetic analysis (Sartiami et al 2020). In 2019 FAW also reportedly attacked in Bandung, Garut, and Sumedang.…”

The endophytic fungi from South Sumatra (Indonesia) and their pathogenecity against the new invasive fall armyworm, Spodoptera frugiperda

“…Maize in Indonesia is currently facing a big problem in invasion and outbreaks of newcomer insect pests, namely the fall armyworm (Spodoptera frugiperda) (Lepidoptera: Noctuidae). S. frugiperda comes from South America (Nagoshi et al 2017;Otim et al 2018) and entered Indonesia for the first time on March 26, 2019 in West Sumatra, then in June 2019 it was found in Banten and West Java (Sartiami et al 2020) and now it has spread rapidly to various provinces in Indonesia, such as South Sumatra (Herlinda et al 2020b;Hutasoit et al 2020), Lampung (Lestari et al 2020), and Bengkulu (Ginting et al 2020). The fall armyworm has caused maize yield losses in Africa of 250-630 million US dollars per year (Bateman et al 2018).…”

Intensitas serangan Spodoptera frugiperda J.E. Smith (Lepidoptera: Noctuidae) pada pertanaman jagung di Kabupaten Garut dan Tasikmalaya, Jawa Barat

“…Smith (Lepidoptera: Noctuidae) atau dikenal dengan nama ulat grayak frugiperda (UGF). Beberapa provinsi di wilayah Indonesia yang sudah melaporkan keberadaan UGF di antaranya Lampung (Trisyono et al 2019), Jawa Barat dan Banten (Maharani et al 2019;Sartiami et al 2020), Sumatera Barat (Sartiami et al 2020), dan Kalimantan Timur (Subiono 2020). UGF adalah ngengat yang dapat bermigrasi dan bersifat polifag sehingga resiko penyebarannya sangat tinggi (Goergen et al 2016).…”

“…Sementara itu, data kerusakan hanya dapat diperoleh dari perhitungan intensitas serangan. Saat ini, penelitian mengenai UGF di wilayah Jawa Barat baru berkisar survei keberadaan dan gejala kerusakannya (Maharani et al 2019;Sartiami et al 2020). Oleh karena itu, penelitian ini bertujuan untuk mengamati intensitas serangan UGF di Kabupaten Garut dan Tasikmalaya yang merupakan salah satu sentra produksi jagung sebagai salah satu langkah awal untuk pemenuhan informasi dasar terkait penentuan tindakan pengendalian UGF agar dapat diterapkan secara tepat dan optimal…”
