Summary: The study examined the expression profiles of lncRNAs and mRNAs in the fall armyworm response to virus infection using RNA sequencing. Differential expression of lncRNAs was observed in response to different viruses and in different tissues. DE-LncRNAs were found to be involved in metabolic processes, DNA replication and repair, immune response, insect hormone metabolism, and cell adhesion. This study provides important insights into the role of lncRNAs in the antiviral defense of the fall armyworm.

Summary: Plants have the ability to defend against herbivores and their resistance mechanisms may vary among different genotypes. This study aimed to test the hypothesis that access to nutrients would alter plant resistance to insects and affect insect performance. The results showed that herbivory reduced insect growth and fertilization affected larval performance. The expression patterns of defense-related genes and proteins differed between genotypes, with herbivory often increasing their expression. Overall, these findings highlight the importance of plant nutrition in the defense against insect herbivory.

Summary: This study investigated the impact of scale thickness on fall armyworm (FAW) egg masses and the parasitoid performance of Trichogramma. The results showed that scale thickness decreases with the age of FAW females. Thinner scale layers result in higher parasitism rates by Trichogramma.

Summary: This study conducted integrated transcriptome and metabolomic analyses to explore the changes in gene expression and metabolic processes in sugarcane leaves after herbivory by the sugarcane pest, Spodoptera frugiperda. Several target defense genes against insect herbivory were identified, providing potential targets for improving sugarcane variety resistance to insect pests through molecular breeding.

Summary: This study investigated the effects of nitrogen supply on the induced defense of maize against the fall armyworm. It was found that appropriate nitrogen supply increased plant biomass and enhanced nutrient contents, leading to increased feeding by the armyworm. However, when combined with herbivore attack or jasmonic acid application, lower nitrogen supply increased susceptibility to pests while higher nitrogen supply improved defense against pests. Changes in nutrient levels and volatile organic compound emissions caused by nitrogen supply could explain these opposite induced defense responses in maize.

Summary: This study found that PHB1 is not a receptor for Vip3Aa, but plays an essential role in mitochondria. The downregulation of phb1 expression in Sf9 cells caused instability of mitochondria, and the cells were more prone to apoptosis when challenged with Vip3Aa. The combined use of Vip3Aa and phb1 RNAi showed a synergistic effect against S. frugiperda larvae.

Summary: This study examined the crawling and ballooning dispersal characteristics of Fall Armyworm larvae, one of the world's most important corn pests. The study found that airflow is a crucial factor in larval ballooning and long-distance dispersal. These findings contribute to field monitoring and control strategies against Fall Armyworm.

Summary: This study investigated the physico-biochemical responses of two maize cultivars, 'ZD958' and 'JG218', to Spodoptera frugiperda infestation through a pot experiment. The results showed that the infestation rapidly induced enzymatic and non-enzymatic defense responses in maize seedlings, affecting cellular oxidation and hormone levels. 'JG218' was found to be more susceptible to S. frugiperda compared to 'ZD958'.

Summary: This review provides a list of practical pest management options for fall armyworm in maize, including host plant resistance, agronomical, cultural, biological, botanical, chemical, and biotechnology approaches. The study found that cultivating tolerant genotypes, adjusting sowing windows, and implementing specific intercultural and cropping system measures, along with chemical and non-chemical pest management strategies, showed promising results for the sustainable management of fall armyworm.

Summary: In this study, G-quadruplex (G4) motifs were identified in the genome of Spodoptera frugiperda, and it was found that they were enriched in genic regions, particularly in the upstream regions of start codons. The G4 structures were more frequently present in the promoters of P450 and CarE gene families. Furthermore, the G4 ligand N-methyl mesoporphyrin IX (NMM) was shown to decrease P450 protein activity in larval midgut tissue, and it had synergistic effects with pesticides on toxicity. These findings suggest that G4 motifs could serve as a potential target for pest control.

Summary: This study investigated the effects of Beauveria bassiana infection on the gut microbial community diversity of Spodoptera frugiperda insects. The results showed that B. bassiana infection significantly altered the gut microbial community, with an increase in the relative abundance of Proteobacteria and Serratia. The infection also had a significant impact on the insect's survival and development, reducing egg hatching rate, larval survival rate, and adult lifespan, while increasing pupae rigor rate. The presence of Serratia marcescens in the insect gut inhibited the virulence of B. bassiana to some extent. These findings provide valuable insights into the interaction between entomopathogenic fungi, hosts, and gut microbes, and suggest a potential strategy for pest control using a combination of entomopathogenic fungi and gut bacteria.

Summary: Insect gut microbiota plays crucial roles in insects, and can be influenced by external factors such as food and antibiotics. This study revealed that antibiotic-induced dysbiosis of gut microbiota affects energy and metabolic homeostasis in Spodoptera frugiperda.
