“…Taking the advantages of stLFR and Hi-C technologies with long fragment reads, super high coverage and reads quality, we de novo assembled a high-quality FAW genome, which is so far the largest FAW genome assembly with a size of 542.42 Mb (Nandakumar et al, 2017;Zhang et al, 2019Zhang et al, , 2020Xiao et al, 2020). The genome of FAW was greatly different (Kakumani et al, 2014;Gouin et al, 2017;Nam et al, 2018Nam et al, , 2019Nandakumar et al, 2017;Zhang et al, 2019Zhang et al, , 2020Xiao et al, 2020) (Table 1), which led to the different genome size and unmapped reads among different individuals. However, the FAW genome assembled in the current study is a high-quality genome in most of the key parameters, including the BUSCO evaluation, WGS mapping rate and RNA mapping rate.…”

With the advancement in genome sequencing and assembly technology, three chromosome-level genome assemblies of FAW have been published or pre-printed (Nam et al, 2019;Zhang et al, 2019Zhang et al, , 2020Xiao et al, 2020).

Genomic and transcriptomic analysis unveils population evolution and development of pesticide resistance in fall armyworm Spodoptera frugiperda

The fall armyworm (FAW), Spodoptera frugiperda, is a destructive pest native to America and has recently become an invasive insect pest in China. Because of its rapid spread and great risks in China, understanding of FAW genetic background and pesticide resistance is urgent and essential to develop effective management strategies. Here, we assembled a chromosome-level genome of a male FAW (SFynMstLFR) and compared re-sequencing results of the populations from America, Africa, and China. Strain identification of 163 individuals collected from America, Africa and China showed that both C and R strains were found in the American populations, while only C strain was found in the Chinese and African populations. Moreover, population genomics analysis showed that populations from Africa and China have close relationship with significantly genetic differentiation from American populations. Taken together, FAWs invaded into China were most likely originated from Africa. Comparative genomics analysis displayed that the cytochrome p450 gene family is extremely expanded to 425 members in FAW, of which 283 genes are specific to FAW. Treatments of Chinese populations with twenty-three pesticides showed the variant patterns of transcriptome profiles, and several detoxification genes such as AOX, UGT and GST specially responded to the pesticides. These findings will be useful in developing effective strategies for management of FAW in China and other invaded areas.

“…The human-assisted spread model 42 was also used to warn China and South East Asian nations of imminent impact by FAW following confirmation of the pest in India 43 . This model further forms the basis of international research efforts to track the movement, including using molecular tools to examine invasion biology (e.g., 19,44,45 ), and simulations to model long distance dispersal (e.g., 42,46,47 ). Indeed a meteorological data-based simulation study (i.e., wind currents, monsoon wind patterns) concluded the Yunnan FAW populations originated from Myanmar, consistent with FAW being officially reported earlier in Myanmar (December 2018 48,49 ) than in China (January 2019 35 ).…”

Accurate genomic knowledge can elucidate the global spread patterns of invasive pests. The highprofile invasive agricultural pest Spodoptera frugiperda (fall armyworm; FAW) is a case in point. Native to the Americas, the FAW was first reported in West Africa in 2016 and has rapidly spread to over 64 countries across the Old World, resulting in significant economic losses. The chronological order of reported detections has led to the hypothesis that the FAW moved eastwards across Africa and then Asia, however genomic evidence remains lacking to test this hypothesis and to identify the potential origin of invasive populations. Using a whole genome sequencing approach, we explored the population genomic signatures of FAW populations from the Americas and the Old World. Analyses of complete mitochondrial DNA genomes identified 12 maternal lineages across the invasive range, while genomic signatures from 870 high-quality nuclear genome-wide single nucleotide polymorphic (SNP) DNA markers identified five distinct New World populations that broadly reflected their native geographical ranges and absence of host-plant preference status. Unique FAW populations in the Old World were also identified that suggested multiple introductions underpinned their rapid global spread. We identified in Asian FAW individuals, genomes lacking evidence of admixture; while analysis of identified complex substructure revealed significant directional geneflow from Asia into East Africa, in contrast to a simple east-towest spread. Our study highlights the need for population genomics approaches in analysing complex pest invasions, and the importance of international partnership to address global biosecurity challenges presented by emerging high priority insect pests.

A fundamental understanding of the underlying mechanisms involved in biological invasions is crucial to developing effective risk assessment and control measures against invasive species. The fall armyworm (FAW), Spodoptera frugiperda, is a highly invasive pest that has rapidly spread from its native Americas into much of the Eastern Hemisphere, with a highly homogeneous nuclear genetic background. However, the exact mechanism behind its rapid introduction and propagation remains unclear. Here, a systematic investigation is conducted into the population dynamics of FAW in China from 2019 to 2021 and found that FAW individuals carrying “rice” mitochondria (FAW‐mR) are more prevalent (>98%) than that with “corn” mitochondria (FAW‐mC) at the initial stage of the invasion and in newly‐occupied non‐overwintering areas. Further fitness experiments show that the two hybrid‐strains of FAW exhibit different adaptions in the new environment in China, and this may have been facilitated by amino acid changes in mitochondrial‐encoded proteins. FAW‐mR used increases energy metabolism, faster wing‐beat frequencies, and lower wing loadings to drive greater flight performance and subsequent rapid colonization of new habitats. In contrast, FAW‐mC individuals adapt with more relaxed mitochondria and shuttle energetics into maternal investment, observed as faster development rate and higher fecundity. The presence of two different mitochondria types within FAW has the potential to significantly expand the range of damage and enhance competitive advantage. Overall, the study describes a novel invasion mechanism displayed by the FAW population that facilitates its expansion and establishment in new environments.
