Recent evidence highlights pronounced geographic and strain-level variation in facultative symbionts, reflecting local adaptation and shaping aphid ecological interactions. Symbiont diversity allows redundancy and functional flexibility, enabling aphids to cope with fluctuating thermal regimes, but may also constrain adaptability if symbiont functionality is compromised. However, how these partnerships govern aphid resilience under climate change remains incompletely resolved. We synthesise evidence that symbionts act as both levers and limits of climate resilience in a context-dependent manner. Key priorities are (1) to identify climatic thresholds that determine failure and recovery of symbiont-mediated provisioning and (2) to document how strain-level variation in symbionts shapes aphid-symbiont interactions across climatic gradients, revealing patterns of resilience and vulnerability. Future research should test how symbionts coexist under climatic stress, including warming effects on symbiont diversity. It should also examine how symbionts modulate interactions with plants, natural enemies and mutualists, while accounting for trade-offs, stability and host-specific outcomes. These goals require climate-gradient field sampling, controlled laboratory experiments and multi-omics to resolve genetic and functional variation, paired with high-resolution measurements of aphid performance under ecologically realistic thermal regimes.

Pollination success depends not only on the presence of flower visitors but also on their behaviour and traits. Although Chile is among the world's leading cherry producers, information on the diversity and pollination roles of insect visitors in its orchards remains scarce. In this study, we used video monitoring to assess the foraging behaviour of floral visitors in 16 conventional orchards in central Chile. In 2023, we recorded 3012 insect visits. Bees comprised 65% of visits, with honey bees (<i>Apis mellifera</i>) alone accounting for 64% and fewer than 1% for wild bees. Besides, 33% of the visits were attributed to flies—mainly <i>Dilophus</i> sp. (Bibionidae) and several syrphid species—and 2% to beetles. Bees spent the shortest time per flower, exhibited greater inter-floral movement and contacted the stigma most frequently, behaviours associated with high pollination potential. In contrast, flies and beetles typically remained longer on flowers, moved little between them and often consumed floral resources without making contact with the stigma. These behavioural patterns suggest that hymenopterans are the most effective pollinators in these systems. Nevertheless, the high abundance of flies in the orchards may partly compensate for their limited pollination efficiency. Additionally, we found a significant positive relationship between body size and the likelihood of stigma contact, highlighting a key morphological trait associated with pollination effectiveness. The overall low diversity and small size of floral visitors in these conventional cherry orchards may explain why few of the species present have the potential to be effective pollinators. Promoting practices that enhance bee floral visitor diversity could increase the presence of alternative pollinators, reduce reliance on managed honeybees and contribute to more stable cherry yields.</p>\u0000 </div>","PeriodicalId":14987,"journal":{"name":"Journal of Applied Entomology","volume":"150 4","pages":"475-486"},"PeriodicalIF":2.0,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147683993","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The behavioural transition in post-mating female insects constitutes a critical adaptive strategy for optimising reproductive success, but little is known about the detailed regulatory molecules. The JAK/STAT signalling pathway has been confirmed to play an important role in insect cell growth, immunity and reproductive processes, but its potential role in post-mating behavioural transformation is still unclear. In this study, we initially identified core components of the JAK/STAT signalling pathway, <i>HaJAK2</i> and <i>HaSTAT5B</i>, in <i>Helicoverpa armigera</i> through screening of the NCBI database and transcriptomic data. Then phylogenetic analysis and multiple amino acid sequence alignment revealed high homology of HaJAK2 and HaSTAT5B with homologues of <i>Spodoptera litura</i> and <i>Helicoverpa zea</i>, respectively. QRT-PCR analysis demonstrated tissue-specific expression patterns of <i>HaJAK2</i> and <i>HaSTAT5B</i>, showing predominant expression in the spermathecae/parovaria tissue. Furthermore, RNAi-mediated gene knockdown experiments indicated that suppressing <i>HaJAK2</i> and <i>HaSTAT5B</i> expression altered post-mating behaviours, including reduced oviposition, extended longevity and diminished re-mating propensity. Finally, we revealed that the transcription factor <i>HaGATAa</i> dynamically regulates the expression of <i>HaJAK2</i> and <i>HaSTAT5B</i>. In conclusion, this study reveals that the GATAa-JAK/STAT axis governs reproductive state-dependent behavioural transitions in lepidopteran post-mating processes, advancing our understanding of insect reproductive strategies and identifying the JAK/STAT cascade as a potential target for novel pest control interventions to disrupt key reproductive behaviours in agricultural pests.</p>\u0000 </div>","PeriodicalId":14987,"journal":{"name":"Journal of Applied Entomology","volume":"150 4","pages":"506-515"},"PeriodicalIF":2.0,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147682969","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
