Despite its tropical origin, this species tolerates moderately low temperatures and has an expansion potential that may be enhanced by global warming. However, the molecular mechanisms underlying cold stress remain poorly understood. This study provides a transcriptomic analysis of its larval response to cold stress. Using RNA-Seq on larvae exposed for 7 d to a sublethal low (5 °C) or control (23 °C) temperature, we identified 701 differentially expressed unigenes (580 protein-coding genes, 81 long noncoding RNAs [lncRNAs], and 40 with transposable elements [TEs]), of which 448 were upregulated and 253 downregulated under cold exposure. Functional enrichment revealed strong repression of cell cycle, along with the induction of stress-responsive pathways, including small heat shock proteins, detoxification enzymes (CYPs, UDP-glucuronosyltransferase), immune effectors (antimicrobial peptides, lectins, peptidoglycan-recognition proteins), and genes involved in cuticle remodeling. A subset of differentially expressed lncRNAs and TE-linked genes was associated with immune and chaperone responses, suggesting multilayered transcriptional regulation. These results indicate that R. ferrugineus larvae respond to low temperature by downregulating non-essential, energy-intensive programs while activating molecular chaperones, detoxification and immune defenses, and reinforcing structural barriers. This pattern, probably underestimated by the stronger starvation stress of controls, is consistent with an integrated strategy involving metabolic depression and enhanced cryoprotection. Our results represent a fundamental step that will guide data-driven studies to determine whether the cold-response mechanisms identified here are fully deployed in R. ferrugineus, as well as for future research on novel pest control strategies.","PeriodicalId":16156,"journal":{"name":"Journal of Insect Science","volume":"26 4","pages":""},"PeriodicalIF":2.3,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13387171/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148549190","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Wolbachia is used in mosquito control strategies, and thermal conditions may shape Wolbachia densities. Species-specific thermal tolerances have been documented in mosquitoes but little is known of thermal impacts on embryos. This study investigated Wolbachia density under elevated cyclical temperatures in Culex quinquefasciatus Say embryos, specifically to determine whether high temperatures reduced Wolbachia density. Experiments used cyclic thermal regimes that simulated high summer temperatures similar to those observed where Cx. quinquefasciatus occurs. The relationship between temperature and Wolbachia density was determined through Fluorescent in-situ hybridization (FISH) and relative quantification based on qPCR. The embryo developmental time and Wolbachia density were reduced at the high cyclic temperature (25 to 40 °C) when compared to the control (25 °C). The time for the embryonic maturation at the high cyclic temperature (25 to 40 °C) was reduced by 8 h compared to development at 25 °C. Integrated fluorescence density of FISH-labeled Cx. quinquefasciatus embryos was significantly lower under the elevated cyclic 25 to 40 °C temperature than at control 25 °C. Relative Wolbachia density by qPCR and ΔΔCt of the wsp gene was also lower under the cyclic elevated temperature. Elevated temperatures which reduce Wolbachia loads may disrupt cytoplasmic incompatibility or antiviral protection. The results herein suggest that environmental thermal regimes could disrupt Wolbachia density in mosquito embryos. This could have implications for Wolbachia‑based disease control strategies and merits further investigation.","PeriodicalId":16156,"journal":{"name":"Journal of Insect Science","volume":"26 4","pages":""},"PeriodicalIF":2.3,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13424437/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148630493","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Instead, many insects must acquire symbionts from their local environments. Without mechanisms for vertical transmission, insects are thought to be at risk of experiencing low fitness by acquiring low-quality symbiont strains. For example, insects dependent on environmental symbiont transmission may acquire nonsymbiotic bacteria or symbionts that are adapted to other co-localized hosts. Yet, insects often appear capable of interacting with a wide variety of symbiont strains, and environmental transmission is prevalent across diverse insect species. Therefore, it remains unclear whether the evolutionary history of a symbiont actually impacts its benefit to hosts. Here, we test whether the recent evolutionary history of a symbiont impacts its quality to an insect host by inoculating Anasa tristis De Geer (Hemiptera: Coreidae) insects with Burkholderiaceae strains isolated from a conspecific host, a distantly related heterospecific host, and from soil. We find that the soil strain offers few fitness benefits. In contrast, both strains with a recent history of host association support insect survival to adulthood, but the greatest benefits emerge from the symbiont isolated from a conspecific host, which also improves insect development rates. Overall, our study demonstrates that the evolutionary history of a symbiont may impact its quality to insect hosts and lays a foundation for future work to further examine whether environmental transmission carries costs for insect hosts.","PeriodicalId":16156,"journal":{"name":"Journal of Insect Science","volume":"26 4","pages":""},"PeriodicalIF":2.3,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13420500/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148620220","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Phylogenetic analyses of the cytochrome c oxidase subunit I gene region provided a framework for comparing setal morphology and geographic distribution among genera. This study is the first to compare and describe the morphology of urticating setae across females of multiple notodontid species.

This study combined a 2-yr field mesocosm experiment (2023-2024) conducted in Gwangneung Forest in the central Korean Peninsula with laboratory analyses of the predatory behavior of the 2 species. Our field experiments revealed that the predation effects of the two species on mosquito larval communities were contrasting: Communities with Lt. vorax showed markedly low mosquito diversity and density, whereas those with Tx. christophi exhibited high diversity and evenness but low dominance. The two predators also showed temporal niche partitioning and different occurrence densities per container. In the laboratory experiment, both species displayed type II functional responses. However, Lt. vorax had a higher attack rate and a shorter handling time than Tx. christophi, yielding a greater theoretical maximum consumption. Only Lt. vorax showed significant preferences in tests using three dominant prey-mosquito species: Aedes koreicus (Edwards), Ae. flavopictus (Yamada), and Tripteroides bambusa (Yamada). Collectively, we propose that Tx. christophi and Lt. vorax each act as key predators that drive mosquito larval communities in opposite directions: Tx. christophi promotes greater diversity and evenness as a keystone predator, occurring at lower densities, whereas Lt. vorax collapses community structure through intense and rapid predation with higher densities per container.","PeriodicalId":16156,"journal":{"name":"Journal of Insect Science","volume":"26 4","pages":""},"PeriodicalIF":2.3,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13425651/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148630560","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
