First record of fall armyworm Spodoptera frugiperda (J.E. Smith (Lepidoptera: Noctuidae) on maize in Viet Nam

Abstract

The neotropical fall armyworm (FAW), Spodoptera frugiperda (J.E. Smith) is an important lepidopteran pest with a broad geographical distribution (Goergen et al. 2015, Early et al. 2018, Sharanabasappa et al. 2018). Larvae of S. frugiperda feed on more than 350 plant species, including several economically-important crops such as maize, sugarcane or rice (Montezano et al. 2018). Following its invasion of the African continent and of South Asia in 2016 and 2018 respectively, FAW has caused important crop losses and associated livelihood impacts (Baudron et al., 2019). During 2019, FAW rapidly spread across Southeast Asia and FAW-attributed feeding damage was recorded on maize in Viet Nam. In Viet Nam, maize is the second most important staple food crop after rice, is extensively used for livestock production and poultry feed, and thus plays a central role in sustaining rural livelihoods (Dang et al. 2004). Hence, the recent FAW invasion and the anticipated pest-induced yield losses will carry important repercussions for local maize value chains and are likely to degrade farmers’ revenue base. In this study, we conducted a morphological and molecular identification of locally-collected FAW individuals to better characterize the species’ invasion history in Viet Nam.

Spodoptera frugiperda (JE Smith) in India: Pervasiveness, Host Range, and Management

“…In 2019, researchers from Sri Lanka (Perera et al 2019), Nepal (Bajracharya et al 2019), the Philippines (Navasero et al 2019), Vietnam (Hang et al 2020) and Indonesia (Trisyono et al 2019) documented incidents of Fall Armyworm (FAW) invasions. The FAW's impact was not limited to Asia, as it also spread to Oceania, as demonstrated by studies conducted by Ma et al (2019), Prasanna et al (2021), andTambo et al (2023).…”

Interspecific Competition between Invasive Spodoptera frugiperda and Indigenous Helicoverpa armigera in Maize Fields of China

“…The fall armyworm (FAW), Spodoptera frugiperda (J. E. Smith) (Noctuidae), native to tropical and subtropical America, is an important invasive pest worldwide [11]. In 2018, FAW invaded India, Southeast Asia (such as Myanmar and Vietnam), and Yunnan Province in China [12][13][14][15], serving as the source population for northern China, Japan, and South Korea [16,17]. Although FAW has been known to feed on 353 host plants across the globe, maize has become the most seriously affected in China, accounting for around 95% of the total area damaged by the pest in 2019 and 2020 [18][19][20][21].…”

Insecticidal efficacy and possibility of Combretum trifoliatum Vent. (Myrtales: Combretaceae) extracts in controlling Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae)

“…It is native to tropical and subtropical areas in the Americas. Since 2016, it has spread on the African continent, and recently, it has been found in Asia and all of southeast Asia, including Thailand 1–4 . The damage caused by the larval stage has been reported in several cultivated economic plant species, principally Poaceae, Asteraceae, and Fabaceae.…”

“…Since 2016, it has spread on the African continent, and recently, it has been found in Asia and all of southeast Asia, including Thailand. [1][2][3][4] The damage caused by the larval stage has been reported in several cultivated economic plant species, principally Poaceae, Asteraceae, and Fabaceae. All plant organs are consumed, especially leaves, stems, and reproductive organs, causing significant losses in product yields.…”
