Abstract ：
Aphids (Hemiptera: Aphididae) are well-known agricultural pests, affecting global crop production both through direct feeding and as the vector of multiple plant viruses. The classification of citrus aphid species was outdated and limited within the Zhejiang Province, China. A comprehensive investigation was conducted to determine the aphid species associated with citrus cultivars from 2019 to 2024. The present study included an analysis of occurrence rate, ecological contexts, and microscope slides photographs of apterous viviparous female, along with the key morphometric parameters such as body length, antenna, rostrum, hind tarsus, cauda, and siphunculi. Our morphological and molecular data revealed five species in this particular citrus region. Among the identified species, Aphis (Aphis) gossypii Glover and A. (A.) spiraecola Patch were the most prevalent, followed by A. (A.) craccivora Koch, A. (Toxoptera) citricidus (Kirkaldy), and A. (T.) aurantii Boyer de Fonscolombe. Furthermore, the genetic variation among aphid clades was assessed using Kimura 2-parameter (K2P) model. The results showed that citrus aphid species exhibits low intraspecific genetic variation and high interspecific genetic variation. Although the morphometric parameters of these aphid species are relatively similar, they can be distinguished through extensive morphological characteristics and cytochrome c oxidase subunit I (COI) fragment. Additionally, this study also addresses the historical and current distinctions among A. (A.) spiraecola and A. (T.) citricidus. These findings will significantly contribute to the ongoing research and management of citrus aphids in citrus plantations.

Abstract ：
Serial grinding microscopy (SGM) facilitates the 3D visualization of organisms and industrial samples across multiple domains. Despite the development of light microscopy using serial slicing techniques for 3D reconstruction of insect specimens, the serial grinding technique has not been explored in entomology. An improved SGM prototype with a standardized workflow was developed, enabling high-resolution 3D visualization and reconstruction of intricate insect structures. The methodology's efficacy was validated through comprehensive testing of insect specimens encompassing a wide range of cuticle types and sizes (e.g. beetles, ants, and fruit flies), as well as an insect fossil in amber. This prototype features the finest x-y plane resolution and a z-axis step distance of 1 mu m. Further exploration of this technique may uncover its potential as a crucial research and diagnostic tool in zoology, other biological domains, and even non-biological materials such as industrial components.

Abstract ：
Insects transmit diverse arthropod-borne viruses. However, it remains largely unknown whether insect innate immune pathways regulate the expression of antiviral factors to mediate the degradation of viral capsids. Here, we discover that transcription factor Dorsal in leafhopper Toll immune pathway binds to the promoter of vertebrate homolog myxovirus resistance-like (MxL) protein to activate its transcription. MxL associates with two different viral particles, promoting ubiquitinated degradation of viral capsids via E3 ubiquitin ligase SIAH1. Notably, MxL forms biomolecular condensates to recruit capsid protein P8 of a destructive rice reovirus and SIAH1. The disordered N-terminal region of MxL is essential for condensate formation. The Arg residue at position 159 of MxL is essential for MxL-P8 interaction and P8 recruitment into condensates. Viral nonstructural protein Pns11 interacts with Dorsal, effectively blocking its nuclear translocation and attenuating antiviral MxL1 expression. Our finding represents the first evidence that MxLs in invertebrates possess broad-spectrum antiviral functions.

Abstract ：
Huanglongbing (HLB), one of the most destructive diseases of citrus, is caused by the fastidious Gram-negative alpha-proteobacteria bacterium Candidatus Liberibacter asiaticus (CLas) and vectored by the Asian citrus psyllid (ACP), Diaphorina citri. Currently, there are no highly effective management strategies for HLB. This review focuses on specific aspects of HLB research, including the global distribution of Candidatus Liberibacter species in citrus, HLB status in major citrus-producing countries and plant-pathogen interactions. The elucidation of virulence effectors used by CLas is explored, focusing on the molecular mechanisms that enable the pathogen to manipulate the host plant, and the insect vector ACP to evade their immune systems. Biotechnological approaches and possible management methods for minimizing HLB and ACP risks are reviewed. This review provides a summary of the CLas Sec-delivered effectors, CLas flagellar genes, tight adherence pilus, transcriptional regulators and facilitates the development of integrated and sustainable solutions to safeguard citrus cultivation.

Abstract ：
Insect Janus kinase/signal transducer and activator of transcription (JAK/STAT) pathway plays a crucial role in antiviral defense, yet how arboviruses activate this pathway remains unclear. Here, we reveal that outer capsid protein of a double-stranded RNA (dsRNA) arbovirus (rice gall dwarf virus, RGDV) directly binds the Dome receptor's extracellular domain, triggering receptor dimerization and JAK/STAT activation. Structural and mutational analyses pinpoint cysteine 743 in Dome as essential for viral recognition, establishing Dome as the first identified viral pattern recognition receptor (PRR) in insects capable of initiating JAK/ STAT signaling, a pathway previously thought to be exclusively cytokine dependent. Furthermore, we identify viperin as a transcriptional factor STAT-regulated antiviral effector with broad-spectrum activity against multiple rice viruses. Intriguingly, RGDV's nonstructural protein Pns11 competitively binds STAT, blocking its phosphorylation by JAK and nuclear translocation, thereby suppressing viperin expression. These findings elucidate how leafhopper Dome functions as a viral PRR and how arboviruses antagonize Dome-JAK-STAT signaling to promote persistent viral infection.

Abstract ：
Janus kinase/signal transducer and activator of transcription (JAK/STAT) immune response traditionally requires cytokine binding to receptors for activation; however, it remains unclear whether cytokine receptors function as direct pattern recognition receptors (PRRs) that recognise viral envelopes. In this study, we demonstrate that cytokine receptor Domeless (Dome) in leafhopper Recilia dorsalis directly recognises glycoprotein (G) of an important rice rhabdovirus. This binding induces Dome dimerisation, which initiates JAK/STAT pathway and leads to STAT-dependent expression of antiviral immune effector in R. dorsalis (RdIE1). RdIE1 suppresses viral replication by inhibiting the RNA-binding activity of viral large polymerase (L). Dome residue T659 is essential for G recognition and L residues E774 and D775 are required for RdIE1 target. Notably, virus-encoded phosphoprotein competitively inhibits the phosphorylation of STAT by casein kinase II (CK2 beta), thereby abrogating STAT-dependent transactivation of target genes. Our findings redefine Dome as a viral sensor and reveal a biphasic strategy that balances antiviral immunity with persistent viral infection in insect vectors.

Abstract ：
Phloem-inhabiting unculturable bacterial pathogens are persistently transmitted by insect vectors. However, how they evade insect immune responses to ensure persistent transmission remains unknown. The important melanization immune response in insects is triggered by cleavage of prophenoloxidase (PPO) into active phenoloxidase (PO) via clip-domain serine proteases (CLIPs). Here, we demonstrate that infection of Candidatus Liberibacter asiaticus (CLas) in psyllid vectors activates the peptidoglycan recognition protein (PGRP)-CLIP1-CLIP4-PPO-PO signaling cascade to induce a mild melanization response, ensuring persistent CLas infection without causing significant insect fitness costs to the insect. A CLas-encoded secretory protein, SDE3230, directly interacts with PGRP and suppresses its activity in transducing this signaling cascade. CLIP4 cleaves PPO between arginine 125 and methionine 126 residues to active PO to induce melanization, and this cleavage pattern in psyllid is distinct from other insects. However, SDE3230 competitively binds to this cleavage site of PPO with CLIP4, thereby suppressing PPO effective cleavage. Collectively, these findings reveal the dual role of SDE3230 in facilitating the mild melanization response, benefitting persistent CLas infection and insect fitness.IMPORTANCEPsyllid-borne huanglongbing is the most destructive citrus disease worldwide, causing billions of dollars in annual production losses and threatening the entire citrus industry. Currently, the mechanism by which the causal agent Candidatus Liberibacter asiaticus (CLas) antagonizes psyllid innate immune responses to facilitate its coexistence with psyllid vectors is still unknown. Here, we report that CLas exploits the highly expressed secretory protein SDE3230 in psyllids to suppress the important melanization immune response in hemolymph via inhibiting the pattern recognition receptor PGRP activity and the cleavage of prophenoloxidase into active phenoloxidase by clip-domain serine proteases. The pattern of PPO cleavage is novel, and this process ultimately ensures persistent CLas infection and insect fitness. Our findings provide insights into how CLas has evolved novel strategies to evade the insect melanization response, thereby facilitating persistent CLas transmission.
