Genome and transcriptome analysis of the beet armyworm Spodoptera exigua reveals targets for pest control
<p>The genus <i>Spodoptera</i> (Lepidoptera: Noctuidae) includes some of the most infamous insect pests of cultivated plants including <i>Spodoptera frugiperda</i>, <i>Spodoptera litura</i> and <i>Spodoptera exigua</i>. To effectively develop targeted pest control strategies for diverse <i>Spodoptera</i> species, genomic resources are highly desired. To this aim, we provide the genome assembly and developmental transcriptome comprising all major life stages of <i>S. exigua</i>, the beet armyworm. <i>Spodoptera exigua</i> is a polyphagous herbivore that can feed from > 130 host plants including several economically important crops.</p> <p>The 419 Mb beet armyworm genome was sequenced from a female <i>S. exigua</i> pupa. Using a hybrid genome sequencing approach (Nanopore long read data and Illumina short read), a high-quality genome assembly was achieved (N50=1.1 Mb). An official gene set (OGS, 18,477 transcripts) was generated by automatic annotation and by using transcriptomic RNA-seq data sets of 18 <i>S. exigua</i> samples as supporting evidence. In-depth analyses of developmental stage-specific expression in combination with gene tree analyses of identified homologous genes across Lepidoptera genomes revealed four potential genes of interest (three of them <i>Spodoptera</i>-specific) upregulated during 1<sup>st</sup> and 3<sup>rd</sup> instar larval stages for targeted pest-outbreak management.</p> <p>The beet armyworm genome sequence and developmental transcriptome covering all major developmental stages provides critical insights into the biology of this devastating polyphagous insect pest species with a worldwide distribution. In addition, comparative genomic analyses across Lepidoptera significantly advance our knowledge to further control other invasive <i>Spodoptera</i> species and reveals potential lineage-specific target genes for pest control strategies.</p>

Analysis of the occurrence of the fall armyworm (Spodoptera frugiperda) in the winter season on the southwestern islands of Japan using the insect's strontium radiogenic isotope ratio (87Sr/86Sr)
<p><em>Spodoptera frugiperda</em>, an invasive pest insect that targets maize and other crops, first arrived in Japan in the summer of 2019. This species occurs year-round in East Asian subtropical regions such as southern mainland China and the island of Taiwan, where the mean air temperature in the coldest month is above 10°C. Adults are similarly found throughout the year on the southwestern islands of Japan. Trap monitoring there showed continuous or intermittent <em>S. frugiperda</em> catches in the 3 winter seasons since 2019. However, it was difficult to distinguish between immigrants arriving from these neighboring areas and local individuals occurring on each Japanese island. In this study, the possible natal origin of captured insects on 5 small islands (Yonagunijima, Taramajima, Okinawajima, Amamioshima, and Tanegashima) was determined by investigating the strontium radiogenic isotope ratios (<sup>87</sup>Sr/<sup>86</sup>Sr) and comparing them with those of reference hosts and insects. Since trapping data and the <sup>87</sup>Sr/<sup>86</sup>Sr values of trapped insects didn't support <em>S. frugiperda</em>'s winter breeding on the northernmost island, Tanegashima, further analysis was limited to the 4 southern islands. The <sup>87</sup>Sr/<sup>86</sup>Sr values of reference host plants and reared insects on the 4 islands ranged from 0.70929 to 0.71009, while those of catch insects ranged from 0.70885 to 0.71090. The <sup>87</sup>Sr/<sup>86</sup>Sr values of the catch insects and the reference on the 4 islands did not differ significantly. In addition, the monthly averages of daily mean air temperature in January and February 2020–2022 were above 10°C, and the wind direction at the surface was mostly from the northeast or northwest. These pieces of evidence, together with winter host availability, suggested that <em>S. frugiperda</em> occurs year-round on the islands. In other words, the year-round occurrence area of <em>S. frugiperda</em> in East Asia extends to the Japanese southwestern islands below Amamioshima Island.</p>
The potential of using different legume species in a push-pull approach to manage Spodoptera frugiperda in maize in China
<p>Fall armyworm (<em>Spodoptera frugiperda</em>)<em> </em>is a notorious pest on crops, especially on maize. The push-pull strategy based on the intercropping system has been reported to effectively reduce the damage of <em>S. frugiperda</em>. However, the suitable mode for <em>S. frugiperda</em> management in maize-based intercropping systems in China has not been reported thoroughly. In this study, the adaptability, feeding, and oviposition preferences of <em>S. frugiperda</em> on maize (<em>Zea mays</em> L.), mung bean (<em>Vigna radiata</em> L.), soybean (<em>Glycine max</em> L.), kidney bean (<em>Phaseolus vulgaris</em> L.), red bean (<em>Vigna angularis</em> Willd.) and cowpea (<em>Vigna unguiculata </em>L. Walp), were firstly compared through lift table analysis and indoor cage tests. Subsequently, based on the results from the laboratory tests, mung bean –cowpea was selected as the push-pull system for <em>S. frugiperda</em> occurrence studied in the field. Results showed that maize is the most suitable host for <em>S. frugiperda</em>, as indicated by the shortest developmental duration and the highest pupal weight. However, among all the tested bean plants, the cowpea is the best for <em>S. frugiperda</em>, on which the larval duration, pre-adults, and adult durations were significantly shorter than others. Meanwhile, the feeding and oviposition preference tests revealed that <em>S. frugiperda</em> had a strong preference for maize and cowpea, while the opposite was true for mung bean. Compared to maize monoculture, the number of eggs of <em>S. frugiperda</em> laid in maize-mung decreased by 67.25%, and that in maize-cowpea significantly increased to 2.04 times. In a randomized block experiment in the field, it was found the incidence of maize in the mung bean-cowpea system was significantly lower than that of maize monocropping and maize only surrounded by cowpea. This study indicated that mung bean and cowpea are promising candidates as a repellent plant (push) and attractant plants (pull) to be intercropped with maize using the push-pull strategy to lessen the damage caused by <em>S. frugiperda</em> in maize-based intercropping systems.</p>
