In this review, we focus on recent advances in cross-species miRNA regulation in insect interactions with microbes, plant or animal hosts. We first provide a brief overview of the general functions of miRNAs in insects. We then summarize current studies on cross-species miRNA regulation in insect interactions with associated organisms, across trophic levels, with particular emphasis on recent studies that functionally characterize translocated miRNAs. In addition, we review current efforts that exploit miRNA translocation for insect pest control. Finally, we highlight major unanswered questions and key challenges in the field of cross-species miRNA regulation. Overall, we argue that research on cross-species miRNA regulation in insect systems is rapidly expanding, although still in its infancy in insect-bacterial symbioses, holds significant potential for advancing our understanding of insect associated interactions and for developing innovative and sustainable pest control strategies.","PeriodicalId":11038,"journal":{"name":"Current opinion in insect science","volume":" ","pages":"101612"},"PeriodicalIF":5.5,"publicationDate":"2026-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148890982","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The concept states that there is a pest density where the cost of damage equals the cost of the insecticide treatment, and this density is used to trigger control actions. The economic injury level thus informs decisions about the need for insecticides based on pest sampling data. However, we argue that the concept often overlooks key biological assumptions about herbivory and typically fails to incorporate the role of crop and pest phenology in optimizing pest sampling and insecticide timing. In this review, we first overview the economic injury level concept and highlight the consequences of these limiting assumptions. We then propose that phenology models that incorporate crop susceptibility and pest life stages, combined with insecticide efficacy data, can allow for better timing of pest management actions. We also suggest that pest monitoring and management decisions should focus on minimizing pest damage accumulation, rather than limiting control actions to predefined thresholds. Future research should focus on effectively leveraging crop and pest phenology models along with field sampling to guide control actions only during the most key management times. While the economic injury level has been a historically important concept guiding pest management theory and practice, adapting the concept to specific crop-pest relationships can ensure more efficient use of pest control inputs.","PeriodicalId":11038,"journal":{"name":"Current opinion in insect science","volume":" ","pages":"101609"},"PeriodicalIF":5.5,"publicationDate":"2026-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148879226","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Within Insecta, one of the most species-rich animal groups, TE content and family richness vary dramatically, yet annotation efforts have historically concentrated on Drosophila, leaving roughly half of non-drosophilid insect TEs classified as unknown. Insect genomes thus represent a vast, largely untapped reservoir of TE diversity. This review guides newcomers through the annotation of TEs in insect genomes, clarifying what can and cannot be achieved with automatic versus manually curated TE libraries. We outline the two core stages of modern annotation: de novo discovery of a representative repeat library, comparing the strategies of popular and emerging tools, followed by genome-wide annotation. We critically examine TE classification, including the promise and current limitations of machine-learning classifiers, and detail best practices for quality control and redundancy reduction. We argue that annotation depth should be dictated by the biological question rather than pursued exhaustively, and we survey both manual curation tools and recent automated curation pipelines. Finally, we address the shift toward pangenomic approaches and the evolving TE database landscape, along with the importance of depositing libraries in versioned, open repositories.","PeriodicalId":11038,"journal":{"name":"Current opinion in insect science","volume":" ","pages":"101610"},"PeriodicalIF":5.5,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148873324","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Occasionally, however, mechanism like horizontal transfer disrupt this isolation and transfers genetic information between species. Transposable elements (TEs), short DNA sequences that can multiply within genomes, are frequently involved in such exchanges. The frequency of horizontal transposon transfer (HTT) between species remains a fundamental open question in biology, as classical sequence comparison approaches may substantially underestimate the true extent of HTT. In this review, we highlight that genomic time-series (GTS), i.e., genomes of specimens sampled across different years in the past, enable an alternative approach that may provide a more unbiased estimate of the true magnitude of HTT between species. Analysis of GTS in fruit flies suggests that HTT may be rampant, with 12 events found over the past 200 years. Species may thus exchange genetic material far more frequently than previously thought. We discuss the pros and cons of different approaches for detecting HTT, show how GTS can be generated for diverse species, and highlight various strategies for identifying HTT events. GTS may generally constitute a valuable resource for addressing a broad range of evolutionary questions.","PeriodicalId":11038,"journal":{"name":"Current opinion in insect science","volume":" ","pages":"101608"},"PeriodicalIF":5.5,"publicationDate":"2026-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148857129","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent studies in the hemimetabolous cricket, Gryllus bimaculatus, have revealed that transforming growth factor-β signaling directly regulates JH biosynthesis. In this system, Decapentaplegic (Dpp) promotes juvenile hormone acid methyltransferase (jhamt) expression and JH production, whereas Myoglianin (Myo) represses jhamt transcription. Functional analyses using RNA interference and CRISPR/Cas9-mediated gene knockout demonstrate that loss of myo leads to sustained JH overproduction, supernumerary molts, and failure of metamorphosis, establishing Myo as a key regulator of developmental timing during nymphal development. This review integrates findings from diverse insect lineages to place Myo-dependent regulation of JH biosynthesis within an evolutionary framework, highlighting its conserved endocrine roles in hemimetabolous insects and its lineage-specific diversification in holometabolous species. Together, these studies provide new insights into how Myo signaling links growth status to endocrine control of developmental progression and metamorphosis.</div></div>","PeriodicalId":11038,"journal":{"name":"Current opinion in insect science","volume":"75 ","pages":"Article 101490"},"PeriodicalIF":4.8,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146017783","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
