Abstract

Fall armyworm or Spodoptera frugiperda (J.E Smith) is a significant economic pest of maize. S. frugiperda is reported for the first time to attack and damage the corn in Indonesia since 2019. The study was aimed to find the effectivity of chlorantraniliprole to control the larvae of S. frugiperda on maize. The study was divided into two steps, in the laboratory and the field. The laboratory treatment was application of chlorantraniliprole 2 cc/l, Metarhizium anisopliae (10? conidia/ml), and Beauveria bassiana (10? conidia/ml) that applied onto the leaf, larvae, and leaf + larvae with five replications for each treatment. The field test used three treatments i.e., chlorantraniliprole field, farmer field, and control with three replications for each treatment. The research showed that chlorantraniliprole at a dose of 2 cc/l had the highest mortality of S. frugiperda with 100% mortality on average during five days after application. However, the application of M. anisopliae and B. bassiana did not affect the mortality of S. frugiperda for 3 days after application. There was no difference in mortality when chlorantraniliprole applied onto leaf, larvae and leaf + larvae. Application of chlorantraniliprole in the field at a dose of 2 cc/l at 1, 3, and 5 weeks after planting was effective to control S. frugiperda on maize.

Abstract

Molecular confirmation of the existence of Spodoptera frugiperda J.E. Smith (Lepidoptera: Noctuidae) on Java Island has not been widely reported. This study aimed to identify the armyworm from Java Island molecularly based on DNA mitochondrial cytochrome oxidase I (MtDNA COI). There were six armyworms collected from West Java Province (Cirebon - JWB1, Garut - JWB2), Central Java Province (Wonogiri - JWTH), East Java Province (Gresik - JWTR), DI Yogyakarta Province (Bantul - DIY), and Banten Province (Serang - BNT). The results showed that the fall armyworm originating from Java was verified as Spodoptera frugiperda. There were genetic variations between them, which had species closeness between regions and countries, namely the genetic similarity of S. frugiperda Java and West Sumatra, as well as to China, Korea, and India. S. frugiperda from Central Java (JWTH), Banten (BNT), West Java 1 (JWB1), and Yogyakarta (DIY) has genetic similarity to S. frugiperda from Solok (No. Acc. MW876212.1), West Pasaman (No. Acc. MW876211.1), China (No.Acc. MK591010.1) and Korea (No.Acc. MN427930.1). Meanwhile, S. frugiperda West Java (JWB2) and East Java have genetic similarity to S. frugiperda from India (No. Acc. MT732476.1), Padang Pariaman (No. Acc. MW876208.1), and Tanah Datar (No. Acc. MW87621.0).
