Understanding its population genetic structure is critical for tracing origins, elucidating dispersal patterns, and informing sustainable pest management. The present study focused on 11 geographically distinct Indian populations (Akola, New Delhi, Hyderabad, Umiam, Parbhani, Solan, Surat, Udaipur, Raichur, Coimbatore, and Kovilpatti) using multilocus mitochondrial DNA markers, viz., <i>cytochrome c oxidase subunits I and II</i> (<i>COI</i> and <i>COII</i>), <i>cytochrome b</i> (Cytb), and 16S rRNA. Phylogenetic analyses revealed moderate genetic differentiation, with no strictly location-specific clades, indicating partial geographic structuring alongside widespread haplotype sharing. COI sequences showed minimal divergence, reflecting strong genetic cohesion and recent common ancestry, while COII and Cytb provided higher resolution for detecting regional variation. The 16S rRNA marker captured deeper evolutionary divergence, particularly among northern, central, and southern populations. Haplotype networks displayed starlike topologies with dominant central haplotypes and multiple low-frequency derivatives, consistent with recent population expansion and high gene flow. Nucleotide polymorphism analyses identified locus-specific hotspots contributing to haplotype differentiation but not to strong population-specific signatures. Overall, Indian <i>C. partellus</i> populations exhibit low-to-moderate mitochondrial diversity and weak phylogeographic structure, suggesting a common genetic origin with extensive contemporary gene flow likely facilitated by contiguous cropping systems, migratory behaviour, and anthropogenic movement. These findings underscore the importance of area-wide integrated pest management strategies and highlight the utility of multilocus mitochondrial markers in resolving both historical and recent population dynamics in migratory insect pests.</p>","PeriodicalId":9370,"journal":{"name":"Bulletin of Entomological Research","volume":" ","pages":"1-11"},"PeriodicalIF":1.6,"publicationDate":"2026-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148041306","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}

Seasonal mean aphid density differed significantly among genotypes for each sowing date. Of the 12 genotypes of wheat studied, two were highly susceptible and two consistently showed lower infestation. Aphid outbreaks peaked between 14 and 27 February, with maximum populations recorded on 20 and 27 February across several genotypes. Natural enemies such as <i>Coccinellids, Chrysopids, Syrphids</i>, and parasitoids displayed significant positive associations with aphid abundance, suggesting they are able to track cues to find prey, and may play a regulatory role. Abiotic factors were strongly predictive of infestation: averaging across all genotypes of wheat, aphid abundance decreased with temperature, with temperature alone explaining 73.5% of the variation in abundance. Aphid abundance also decreased with hours of daylight (explaining an additional 14.1% of the variation in abundance). These findings demonstrate that aphid population dynamics in wheat are genotype-specific and environmentally driven, with mid-to-late February identified as the most critical infestation window.

Understanding how local and landscape factors shape spider assemblages throughout the season is essential for designing effective agro-ecological infrastructures that can sustain their services in crop systems. We investigated ground-dwelling spider communities in Belgian winter cereal fields and their margins. Pitfall traps were used across seasons to assess the effects of habitat (field vs. margin), surrounding crop cover, and seasonal dynamics on spider richness, activity-density, and community structure. Results show that spider activity-densities were consistently higher in margins than in fields, whereas species richness showed no significant differences between these habitats. Significant seasonal variations were detected on both spider richness and abundance. The landscape effect of the annual crop cover was context dependent, showing seasonal and species-specific patterns and even positive associations in autumn. Seasonal shifts also reflected life stage and sex-specific phenologies. This study reveals that spider communities in Belgian cereal systems are shaped by interacting local, landscape, and seasonal factors. Margins mainly act as refuges that bolster spider numbers rather than species pools, while the influence of the surrounding landscape depends on the season and the species identity. These findings highlight the need to incorporate temporal and biological context when designing margins and other agro-ecological infrastructures to support natural pest regulation providers such as spiders.</p>","PeriodicalId":9370,"journal":{"name":"Bulletin of Entomological Research","volume":" ","pages":"1-13"},"PeriodicalIF":1.6,"publicationDate":"2026-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147763297","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}
