Abstract ：
Plants have developed various resistance mechanisms against herbivorous insects through prolonged coevolution. Plant defence responses can be triggered by specific compounds present in insect saliva. Apyrase, a known enzyme that catalyzes the hydrolysis of adenosine triphosphate (ATP) and adenosine diphosphate (ADP) into adenosine monophosphate (AMP) and inorganic phosphorus, has recently been identified in some herbivorous insects. However, whether insect salivary apyrase induces or inhibits plant responses remains poorly understood. In this study, we identified an apyrase-like protein in the salivary proteome of the fall armyworm, Spodoptera frugiperda, named Sfapyrase. Sfapyrase was primarily expressed in the salivary gland and secreted into plants during insect feeding. Transient expression of Sfapyrase in tobacco and maize enhanced plant resistance and resulted in decreased insect feeding. Knockdown of Sfapyrase through RNA interference led to increased growth and feeding of S. frugiperda. Furthermore, we showed that Sfapyrase activates the jasmonic acid signalling pathway and promotes the synthesis of secondary metabolites, especially benzoxazinoids, thereby enhancing resistance to S. frugiperda. In summary, our findings demonstrated that Sfapyrase acts as a salivary elicitor, inducing maize jasmonic acid defence responses and the production of insect-resistant benzoxazinoids. This study provides valuable insights into plant-insect interactions and offers potential targets for developing innovative insect pest management strategies.

Abstract ：
Research on the interactions between herbivorous insects and plants, facilitated by insect secretions, has increasingly emphasized species with chewing mandibles over time. However, the molecular mechanisms underlying the interaction between Spodoptera frugiperda and plants remain poorly understood. In this study, we identified a protein disulfide isomerase (SfPDI) from the salivary glands of S. frugiperda that regulates the interaction between S. frugiperda and plants. We found that SfPDI is highly expressed in the salivary glands of S. frugiperda and is secreted into plants as a secretory protein. The RNAi revealed that SfPDI contributes to the growth and development of S. frugiperda on host plants, while its overexpression in tobacco induces necrosis in tobacco leaves and triggers a burst of reactive oxygen species (ROS). Differentially expressed genes suggested that SfPDI may suppresses the expression of plant JA by positively regulating MYC2 and TIFYs and negatively regulating WRKYs. Notably, SfPDI may modulate these high expression of receptors (NB-LRR, GL-RLK, and RLK) lead to hypersensitive response (HR) cell death and the accumulation of lignification of plant. This study provides a foundation for further exploring insect-plant interaction mechanisms and a theoretical basis for developing insect-resistant germplasm and environmentally friendly pest control strategies.

Abstract ：
Tuta absoluta is a significant agricultural pest primarily affecting Solanaceae plants, resulting in substantial economic losses in agriculture. Insect saliva is an intermediary between insects and plants, playing a crucial role in modulating host adaptability and plant defense. This study analyzed the adaptive differences of T. absoluta on four plants using the two-sex life table method. Results indicated that the host adaptability of T. absoluta to tobacco is worse than its adaptability to the other three varieties of tomatoes. The salivary gland transcriptome analysis and signal peptide prediction revealed that Trypsin, B5 V51-1498, and Ta74 were highly expressed in the salivary glands of T. absoluta subjected to tobacco treatment and exhibit the characteristics of secretory proteins, alongside significant feeding selection differences. Our findings elucidate the adaptive strategies of T. absoluta larvae on various Solanaceae plants and offer new insights into the salivary protein-mediated plant defense processes.

Abstract ：
The invasion of the fall armyworm poses substantial threats to local agricultural safety, including the sugarcane industry. Exploring the insect-resistance mechanism is crucial for breeding resistant varieties. This study selected three representative materials from the Saccharum genus-Saccharum officinarum L. (Badila), S. spp. hybrid (GT58), and Saccharum spontaneum (SES208), to investigate feeding preferences and developmental fitness of Spodoptera frugiperda. Larvae exhibited a strong preference and highest fitness parameters in Badila leaves compared to SES208. Additionally, proteomic analyses of larval saliva from insects feeding on Badila and SES208 were carried out to test the types and abundance of proteins on different hosts. Furthermore, we identified fatty acid-binding protein 1-like activates plant defense responses, while aldehyde dehydrogenase negatively suppressed plant defense response. Our findings suggest that the plasticity of salivary proteins induced by different host plants, and also offer new insights into the molecular interactions between S. frugiperda and plants.

Abstract ：
Sugarcane (Saccharum spp. hybrid) is the primary sugar crop in China, which accounts for over 86 % of the nation's total sugar output. However, sugarcane cultivation faces increasing threats from different insect species, among which the stem borers stand out as the most destructive pests for sugarcane yield. These pests undergo multiple generations per year, leading to escalating infestations. In the current review, we first introduced the occurrence patterns and economic losses caused by stem borers in China. Then, we compared current integrated pest management (IPM) strategies for stem borers including chemical communication, biological control, pesticides and resistant varieties domestic and international. In light of scientific advancements, emerging technologies such as transgenic insect-resistant sugarcane, RNA-based pesticides, the Sterile Insect Technique (SIT) and AI-driven intelligent control technologies show promise for future pest control efforts. This review specifically focuses on sugarcane stem borers management, providing insights into regional pest dynamics, climate-adaptive control strategies and emerging biotechnological solutions tailored to future sugarcane pest management practices.

Abstract ：
Spodoptera frugiperda possesses a remarkably broad host range and causes substantial economic losses in global agricultural production. Insect saliva secreted onto plant surfaces plays a vital role in regulating both plant defense responses and insect adaptation. However, the mechanisms by which S. frugiperdasalivary proteins that respond to plant defense responses and regulate host adaptation remain elusive. The two-sex life table evaluation indicates that the host adaptability of S. frugiperda varies under different feeding schemes. Transcriptome analysis of differentially expressed genes in the salivary glands revealed that PTL, CSP2, and SPI are specifically responsive to host plants but not to an artificial diet. In S. frugiperda fed on adaptive host plants, the primary secretory proteins PDI and esterase FE4 are involved in enhancing host adaptation. When fed on nonadaptive host plants, S. frugiperda invests more energy in synthesizing detoxification metabolic enzymes such as trypsin, SPSL, and CLE2A. This study offers valuable insights into the adaptation mechanisms of phytophagous insects and identifies candidate genes involved in insect-plant interactions, offering targets for sustainable pest control strategies.

Abstract ：
The microRNAs (miRNAs) play an important role in the regulation of gene expression, influencing the outcome of many biological processes in insects. The introduction of miRNA into the insect body can lead to pest developmental abnormalities indicating that miRNAs are potential targets for pest control. In this study, we employed small RNA sequencing to characterise and analyse the expression of miRNAs in the sugarcane shoot borer Chilo infuscatellus (Snellen). By integrating previously published transcriptome sequencing data, we predicted and identified miRNAs and their target genes involved in the ecdysone metabolic pathway. We confirmed the target relationships between Ci-miR-4, Ci-miR-5 and CiCYP18A1 by RT-qPCR and dual-luciferase reporter assays in vivo and in vitro. Additionally, injection of miRNA mimics reduced the transcripts of CiCYP18A1 and led to abnormal moulting, which is similar to the defect phenotype of depletion of CiCYP18A1 by dsRNA. Furthermore, we also mixed the synthesised Ci-miR-5 mimic into artificial diets and found similar stunting results of the injection method. These results demonstrated that Ci-miR-5 could target CiCYP18A1 to regulate the moulting process and the successful use of an insect miRNA for gene silencing studies in this sugarcane pest. The method provided an effective novel approach for future RNAi-based pest control strategies.

Abstract ：
BACKGROUND: The fall armyworm, Spodoptera frugiperda, is one of the most dangerous pests to various crops. As the most crucial sugar crop, sugarcane is also constantly threatened by these pests. Plant wound-induced proteinase inhibitors (WIP) are natural defense proteins that play important roles in the defense system against insect attack. Breeding for resistance would be the best way to improve the variety characteristics and productivity of sugarcane. Screening and verification for potential plant endogenous insect-resistant genes would greatly improve the insect-resistant breeding progress of sugarcane. RESULTS: A sugarcane WIP5 gene (ScWIP5) was up-regulated 536 times after insect feeding treatment on previous published transcriptome databases. ScWIP5 was then cloned and its potential role in sugarcane resistance to fall armyworm evaluated by construction of transgenic Nicotiana benthamiana. The toxicity of ScWIP5 transgenic N. benthamiana to fall armyworm showed lower weight gain and higher mortality compared to wild-type N. benthamiana feeding group. Furthermore, the concentration of JA and NbAOC, NbAOS, and NbLOX from the Jasmin acid biosynthesis pathway was significantly induced in ScWIP5 transgenic N. benthamiana compared to the control. In addition, digestive enzyme actives from the insect gut were also evaluated, and trypsin and cathepsin were significantly lower in insects fed with ScWIP5 transgenic N. benthamiana. CONCLUSION: These results indicate that ScWIP5 might enhance insect resistance by increasing JA signal transduction processes and reducing insect digestive enzyme activities, thus impacting insect growth and development.

Abstract ：
昆虫和植物是自然界生物类群中重要的组成部分,在长期进化的过程中形成了复杂的相互作用关系,如植物进化出了复杂的防御策略来抵御昆虫为害,同时,昆虫为了获取更多的生存资源也进化出了更多的适生方式。因此,分析和了解昆虫与寄主植物相互适应的研究进展对害虫的有效防治和抗虫植物的培育具有重要作用。在昆虫与寄主植物互作的研究中,植食性昆虫的口腔分泌物(唾液或反刍液)、卵分泌物、肠道合成物及微生物等作为连接昆虫和植物的中间媒介,其有效成分不仅起着诱导或增强植物防御的作用,而且部分还具有抑制或削弱植物防御的功能,因此,按有效成分发挥的作用,植食性昆虫的口腔分泌物主要可分为激发子和效应子。本文从昆虫分泌物的角度介绍了昆虫钙结合蛋白类、酶类效和毒液蛋白类等效应子以及脂肪酸氨基酸共轭物类、多肽类和酶类等激发子以及介导植物防御的主要方式,明确了植食性昆虫适应寄主植物防御的不同策略,不仅有助于对昆虫植物两者互作机制的深入解析,而且为绿色有效防治害虫和植物抗性品种的选育提供新的思路。
