The composition of HIPVs is often specific to the herbivore species, and infestation by multiple herbivore species produces a distinct volatile blend compared to single infestations, potentially influencing tritrophic interactions. Although two decades of research have investigated how multiple herbivory can affect chemically-mediated tritrophic interactions, a comprehensive understanding on this topic remains elusive, as studies have shown varying results depending on the system examined. We performed a quantitative synthesis of 29 studies, extracting effect sizes from 94 experiments that assessed the olfactory preferences of NEs for HIPVs emitted from multiple-infested and single-infested plants. Our analysis revealed that multiple infestations do not affect the attractiveness of HIPVs to NEs, regardless of whether the plant is infested by nonhosts, hosts from different or the same feeding guild, the NE dietary specialization, or guild. However, specialist NEs prefer HIPVs emitted from plants with hosts even if they are infested by multiple herbivores over those infested by only a single non-host herbivore. Our meta-analysis provides valuable insights into the complexity of chemically-mediated tritrophic interactions, demonstrating that the co-infestation with nonhosts or multiple hosts do not affect attractiveness of HIPVs to NEs.</p>","PeriodicalId":11038,"journal":{"name":"Current opinion in insect science","volume":" ","pages":"101347"},"PeriodicalIF":5.8,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143457144","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}

Immune cells, or hemocytes, are integral components of the arthropod innate immune system with notable roles in defining vector competence. Evidence suggests that both blood feeding and infection drive substantial changes in hemocyte phenotypes, including proliferation, immune activation, and differentiation, which directly and indirectly influence pathogen infection outcomes. These dynamics have fueled extensive research into hemocyte biology in recent years, which aided by emerging single-cell technologies and methods of phagocyte depletion, have provided novel molecular insights into hemocyte populations and additional support for their important contributions to parasite, virus, and bacterial infections. Despite this progress, many aspects of arthropod immune cell biology remain unclear. Focusing on mosquitoes and ticks as two of the most prominent and well-studied arthropod vectors, this review summarizes the effects of blood feeding and infection on mosquito and tick hemocytes, highlighting hemocyte classifications, and the known mechanisms by which hemocytes can have positive or negative impacts on vector-borne pathogen infection.</div></div>","PeriodicalId":11038,"journal":{"name":"Current opinion in insect science","volume":"69 ","pages":"Article 101341"},"PeriodicalIF":5.8,"publicationDate":"2025-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143406294","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, throughout the off-season, insects must overcome resource shortages and adverse climates to survive. This off-season persistence affects pest infestations in subsequent crops or seasons. Key pest species employ diapause, migration, and local-scale dispersal to persist during the off-season. Genomic approaches have advanced our understanding of these survival mechanisms. Clock genes regulate the circadian rhythm and interact with neuropeptides and downstream pathways, such as insulin-like peptides and hormonal factors–like ecdysteroids and juvenile hormones that regulate diapause. Migrant insects must manage processes like energy metabolism, oogenesis, and flight orientation. Local-scale dispersal requires mechanisms to locate, select, and exploit the most suitable host and habitat for survival and reproduction during the off-season. Here, we present advances in genomic research on pest survival during the off-season, focusing on diapause, migration, and local-scale dispersion.

We present a novel approach to mite management emphasising the role of immigration. We argue that how mite numbers increase within the colony determines the most effective varroa management techniques. That is, varroa infestations go through phases, where their rate of increase is either driven by varroa reproduction (Chronic phase) or is strongly influenced by immigration into the hive (Acute phase). Identifying chronic and acute phases will enable current varroa control methods to be better targeted. For example, control methods reducing reproduction rates will be most effective during the chronic phase. Identifying when immigration is important to varroa in-hive population increases (acute phase) may enable existing bee management techniques, for example, those that limit the access of some bees into hives, to be co-opted into varroa management. This change in perspective emphasises that in-hive varroa control will be improved by understanding the subtleties of how and when varroa enter hives; it will also identify other gaps in our knowledge of varroa’s behavioural ecology that could lead to new varroa control methods. Therefore, this novel approach to mite management will enable Integrated Pest Management to be better tailored to this pest.</div></div>","PeriodicalId":11038,"journal":{"name":"Current opinion in insect science","volume":"68 ","pages":"Article 101343"},"PeriodicalIF":5.8,"publicationDate":"2025-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143255038","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

I emphasise the importance and methods of early detection, citizen science, public involvement, and the role of advanced technologies, such as artificial intelligence, drones, and radio telemetry for nest detection. Toxic baits remain a vital tool for population suppression, although improvements in their efficacy and selectivity are needed to mitigate nontarget impacts. The review explores the development of targeted control tools, including emerging biological and genetic control methods, which promise potential solutions but require careful consideration of ecological risks. Genetic interventions include gene drives that offer future potential for sustained long-term control but require robust regulatory frameworks. Global collaboration to standardise management is essential, as invasion and control efforts in one region can affect neighbouring countries. The integration of international best practices with legal frameworks, public engagement, and adaptive management strategies will be critical to the success of future management programmes.</div></div>","PeriodicalId":11038,"journal":{"name":"Current opinion in insect science","volume":"68 ","pages":"Article 101336"},"PeriodicalIF":5.8,"publicationDate":"2025-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143064400","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
