This study investigated circadian rhythms in Scolytinae communities using flight interception traps in an oak forest in the southern part of Czechia. Ordination biplot revealed a flight activity gradient, with nocturnal dispersers distinct from diurnal species. Species richness gradually decreased from the 20:00-24:00 interval through to the 12:00-16:00 interval, with the most notable decline observed between the 08:00-12:00 and 12:00-16:00 intervals. A combination of fourth-corner and partial canonical correspondence analyses identified tribal affiliation, trophic specialisation, and microhabitat preference as key drivers of flight structuring. Members of the tribe Xyleborini showed negative association to the 16:00-20:00 interval. Xylomycetophagous species, such as <i>Xyleborinus saxesenii</i> exhibited multimodal activity peaks, with increased flight from nighttime to early morning. In contrast, species that feed in the phloem such as <i>Scolytus intricatus</i> showed no significant association with any specific time interval. Several species that utilise stumps as potential breeding substrates showed significantly reduced flight activity during the crepuscular period, which supports the hypothesis that microhabitat preference contributes to diel periodicity. Our findings show the complex interplay between abiotic and biotic factors in shaping circadian flight periodicity, which leads to distinct flight activity patterns between Scolytini bark and Xyleborini ambrosia beetles. These results emphasise the ecological significance of maintaining heterogeneous forest structures that provide a balance of shaded and sun-exposed deadwood habitats to support diverse assemblages.</p>","PeriodicalId":9370,"journal":{"name":"Bulletin of Entomological Research","volume":" ","pages":"1-11"},"PeriodicalIF":1.6,"publicationDate":"2025-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144944075","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}

In this study, We identified five key <i>GST</i> genes (<i>TaGSTs1, TaGSTs2, TaGSTe1, TaGSTe3</i>, and <i>TaGSTd1</i>) by screening from the comparative transcriptomes of two regional populations of <i>T. absoluta</i> in Xinjiang, China. Among the five GSTs, <i>TaGSTs1</i> exhibited a significantly high expression level during the larval stage of <i>T. absoluta</i> following exposure to the LC₅₀ dose of spinetoram. This gene was subsequently cloned, and its expression was knocked down using RNA interference to further analyse its role in the detoxification of spinetoram, as well as in the growth and development of <i>T. absoluta</i>. The results showed that <i>TaGSTs1</i> contains a typical <i>GST</i> gene domain and was highly conserved within the Lepidoptera clade. Silencing of the <i>TaGSTs1</i> gene led to a significant increase in the susceptibility of <i>T. absoluta</i> to spinetoram, as evidenced by an extension in the duration of leaf-mining and in the development time from the 2^nd to the 4^th instar larval stage, which were 35.7% and 19.6% longer, respectively, than those of ddH₂O and ds<i>GFP</i> controls. Furthermore, the mortality rate of larvae treated with ds<i>TaGSTs1</i> reached 57.3% by the 7th day.

This wasp species is widely utilised in biological control programmes targeting these economically significant lepidopteran pests. In this study, the sublethal effects of four insecticides (tetranelypyrole, flupyradifurone, flubendiamide, and spirotetramat) on the biological parameters of the parasitoid wasp <i>H. hebetor</i> were investigated using demographic toxicology methods.

Differential gene expression analysis, coupled with GO and KEGG pathway annotations, facilitated the identification of olfactory receptor genes. The reliability of transcriptome data was subsequently validated through quantitative real-time-polymerase chain reaction analysis. Transcriptomic analysis revealed 12,356 differentially expressed genes (DEGs) between inhibitor and control groups, with 276 genes showing significant differential expression. Similarly, 12,356 DEGs were identified between the agonist and control groups, among which 672 genes exhibited significant differential expression. The GO annotation revealed that the DEGs in the inhibitor group and the agonist group were mainly enriched in the biological process such as cellular process, metabolic process, and biological regulation; in cellular component, enrichment was mainly observed in cell, cell part, and organelle; and in molecular function, the main enrichment was in binding and catalytic activity. KEGG pathway analysis indicated that DEGs from both groups were primarily enriched in signal transduction pathways. Among the DEGs, three olfactory receptor genes were identified in the inhibitor group: odorant receptor 19, odorant receptor 22, and odorant receptor 5. The agonist group exhibited two olfactory receptor genes: odorant receptor 109 and odorant receptor 26. All these olfactory receptor genes demonstrated downregulated expression patterns.
