“…The inherently superior biological characteristics of S. frugiperda such as high fecundity, strong migratory ability, and wide range of hosts contribute to its invasiveness [3]. In the last 3 years, it has invaded 47 African countries, 18 Asian countries, and Australia [4]. Spodoptera frugiperda was first detected in Africa in January 2016 and rapidly spread to sub-Saharan Africa [5,6].…”

Background Spodoptera frugiperda (JE Smith), or fall armyworm, is one of major migratory agricultural pests with a wide range of hosts. The effect of different hosts (maize and kidney bean) on the growth and reproduction of S. frugiperda were investigated using the age-stage, two-sex life table method. Results The results showed that S. frugiperda could complete its entire life cycle on both hosts, albeit with significantly different development and reproduction. The durations of larval and pupal development were significantly prolonged whereas adult lifespan was shortened on kidney bean compared to maize. The differences of survival rates at each instar, prepupal and pupal stages between the two hosts were not statistically significant. The total pre-oviposition period was longer on kidney bean than that on maize (42.05 vs 39.04 days), but there was no difference in the oviposition rate (64.77 on kidney bean vs 62.48 on maize). The differences of net reproductive rate, intrinsic rate of increase and finite rate of increase were nonsignificant, while the mean generation time on kidney bean (42.05 days) was significantly longer than that on maize (40.92 days). Conclusions The results indicate that S. frugiperda can grow and reproduce normally on both hosts, although maize is more suitable. Nonetheless, the data show that this pest is harmful when the population density is high or when the preferred host is scarce. Graphic abstract

“…Therefore, this pest seriously threatens corn production and food security around the world [2][3][4]. At present, the S. frugiperda has invaded 46 countries or regions of Africa and nine countries of Asia [5][6][7]. In January 2019, S. frugiperda was first discovered in a cornfield of Jiangcheng City, Yunnan Province, China.…”

As an accurate and convenient technique, the qRT-PCR is always used in the quantitative expression analysis of functional genes. Normalization of the data relies on stable reference genes. The fall armyworm Spodoptera frugiperda (J. E. Smith) is an important invasive and migratory pest that seriously threatens corn production around the world. In this paper, we selected 10 candidate reference genes (18S, AK, RPL10, RPS24, 28S, SOD, ATP, GAPDH, ACT, and a-TUB) and determined their expression levels under different conditions (different developmental stages, various tissues, mating status, hormones, diets, and temperatures). Subsequently, the stability of reference genes was evaluated by four algorithms (Delta Ct method, geNorm, NormFinder, BestKeeper). The optimal combination of reference genes for each treatment was obtained by geNorm. Finally, the comprehensive ranks were determined by the online tool RefFinder. Results showed that the most stable reference genes were SOD, RPL10, and RPS24 for developmental stages, α-TUB, RPL10, and ATP for different tissues, AK, RPL10, and 18S for mating status, 18S and AK under hormone treatment, 18S, RPL10, and SOD under diet treatment, RPL10, 18S, and RPS24 under temperature treatment. This study confirmed recent data on a few reference genes and provided an evaluation of a number of additional reference genes of S. frugiperda under various conditions.

“…It is one of the most dangerous invasive pests originated from the tropical and sub-tropical regions of the Americas ( Capinera, 2002 ). FAW possesses a wide range of hosts, including at least 353 plants belonging to 76 families, such as corn, wheat, rice, sorghum and others ( Wan et al, 2020 ), it has caused great damage to crops, thus leading to huge economic losses to agriculture. FAW is an alien invasive pest in China and quickly invaded the Yunnan Province, southern China in December 2018 ( Sun et al, 2021 ; Wu, Jiang & Wu, 2019 ).…”

“…At the end of 2020, it had colonized corn fields of 1,338 counties of 27 provinces in China, and the damaged area caused by FAW has reached as high as 11,125–12,780 hectares ( Zhou et al, 2021 ). FAW adult has a strong capability of long-distance migration, and the average flight distance was more than 100 km per night under proper environmental conditions ( Tendeng et al, 2019 ), which aggravating its rapid spreading ( Wan et al, 2020 ). Additionally, the fecundity of FAW is extremely high, the average number of laying eggs per female is 1,052–1,323 ( Wan et al, 2020 ).…”

Background Spodoptera frugiperda (J. E. Smith), commonly known as fall armyworm (FAW), is one of the most destructive agricultural pests in the world and has posed a great threat to crops. The improper use of insecticides has led to rapid development of resistance. However, the genetic data available for uncovering the insecticide resistance mechanisms are scarce. Methods In this study, we used PacBio single-molecule real-time (SMRT) sequencing aimed at revealing the full-length transcriptome profiling of the FAW larval brain to obtain detoxification genes. Results A total of 18,642 high-quality transcripts were obtained with an average length of 2,371 bp, and 11,230 of which were successfully annotated in six public databases. Among these, 5,692 alternative splicing events were identified.
