Abstract The wild rats in the genus Rattus represent a group of murids characterized by rapid lineage diversification but limited morphological variation. Within this genus, there are several commensal species with high invasive capacity, such as norvegicus and R. rattus , which pose global threat. Investigating mechanisms behind their adaptive evolution is utmost importance. In study, we conducted study whole‐genome sequencing on distributed China adjacent regions to gain insights into differentiation, well genomic divergence gene flow using assembled mitochondrion genome high‐quality single nucleotide polymorphisms. Despite similarity large overlap morphospace, our analyses revealed significant genetic differentiation at level among regions. Specifically, intraspecific was observed nitidus tanezumi may be related habitat heterogeneity geographic isolation. We hypothesize that expand habitat, ecological environments might lead more environmentally adapted accelerated differentiation. Furthermore, Dsuite TreeMix detected substantial introgression different species, particularly evident between R . Strong signals suggest frequent hybridization events these facilitate acquisition new environmental adaptability during expansion territories. This provides preliminary analysis serves foundation for comprehensive investigation species.

Climatic variation stands as a significant driving force behind genetic differentiation and the evolution of adaptive traits. Chilo (C.) suppressalis, commonly known rice stem borer, is highly destructive pest that crucially harms production. The lack natural population genomics data has hindered more thorough understanding its climate adaptation, particularly basis underlying To overcome this obstacle, our study employed completely resequenced genomes 384 individuals to explore structure, demographic history, gene flow C. suppressalis in China. This observed occurred asymmetrically, moving from central populations peripheral populations. Using genome-wide selection scans genotype-environment association studies, we identified potential loci may be associated with climatic adaptation. most robust signal was found cold tolerance, linked homeobox gene, goosecoid (GSC), whose expression level significantly different low high latitudes. Moreover, downregulating by RNAi enhances tolerance phenotypes. Our findings have uncovered delved into foundation ability adapt environment. essential ensuring continued effectiveness sustainability novel control techniques.

Abstract BACKGROUND Helicoverpa armigera is a highly polyphagous species that causes huge losses to agricultural and horticultural crops worldwide. In the cotton industry, H. armigera, including Australian subspecies conferta , largely managed using genetically modified express insecticidal toxins, such as Cry1Ac. Resistance Cry1 proteins occurs and, in some cases, mediated by changes HaCad1 gene encodes midgut protein cadherin. Around world, numerous resistance‐associated polymorphisms have been identified of but Cry1Ac resistance rare subspecies. We used CRISPR/Cas9 disrupt cadherin characterised resulting phenotype with bioassays transcriptomics. RESULTS Compared parental strain, newly generated knockout strain 44‐fold 16‐fold more resistant Cry1A.105, respectively, while wild‐type insects were equally insensitive Cry1F.

Sex pheromones play crucial role in mating behavior of moths, involving intricate recognition mechanisms. While insect chemical biology has extensively studied type I pheromones, II remain largely unexplored. This study focused on Helicoverpa armigera, a representative species noctuid moth, aiming to reassess its sex pheromone composition. Our research unveiled two previously unidentified candidate pheromones-3Z,6Z,9Z-21:H and 3Z,6Z,9Z-23:H-in H. armigera. Furthermore, we identified HarmOR11 as an orphan receptor 3Z,6Z,9Z-21:H. Through AlphaFold2 structural prediction, molecular docking, dynamics simulations, elucidated the basis key residues governing sensory nuances both receptors, particularly HarmOR13. not only reveals presence but also establishes comprehensive framework for PRs, contributing understanding connections between evolutionary adaptations emergence new types.
