Summary: The cosmopolitan family Cleridae with approximately 4000 species has been studied for the first time using mitochondrial genomes to reconstruct its phylogeny and determine the timing of divergence. The results support the monophyly of the family and each subfamily, with Korynetinae sister to the remaining clerids, and provide a time estimate of the earliest divergence of Cleridae not later than 160.18 Mya during the mid-Jurassic, demonstrating the importance of mitochondrial biology in understanding the evolutionary relationships within the family.

Summary: The mitochondrial genomes of six species of Phylloscopus were sequenced using the Illumina platform. The genomes were circular molecules of about 17,000 base pairs, containing various genes and control regions. The gene order was conserved among the samples, and the phylogenetic analysis showed the evolutionary relationships between the species. These findings provide valuable resources for studying the taxonomy and phylogenetic history of Phylloscopidae.

Summary: Using mitochondrial phylogenomic analyses of 139 mitochondrial genomes, the study reveals the major interfamilial phylogeny of Chalcidoidea. The results suggest that Chalcidoidea arose near the Jurassic/Cretaceous boundary and underwent two dynamic shifts in diversification. The potential codiversification between chalcidoids and their hosts may have played a crucial role in accelerating the diversification of Chalcidoidea.

Summary: This study compared and analyzed the mitogenome features of parrotfish species and found that they exhibited both conserved and unique characteristics. The structure and organization of the mitogenomes were relatively conserved, while the base composition and intergenic spacers varied. The phylogenetic analysis revealed two clades of parrotfishes with distinct ecological adaptations, with early divergence likely associated with sea grass expansion and later diversification linked to geomorphology alteration since the closing of the Tethys Ocean. This research provides fundamental materials for further studies on parrotfish evolution and conservation.

Summary: This study focuses on the impact of parasitoid Cotesia vestalis on the immune system of its host, the diamondback moth. The findings reveal that parasitization by Cotesia vestalis leads to a decrease in host hemocytes, disrupting the encapsulation reaction. Moreover, a viral gene called CvBV_28-1 is highly expressed in the hemocytes of parasitized hosts and plays a role in inhibiting the proliferation of host hemocytes. Additionally, CvBV_28-1 demonstrates the ability to clear gram-positive bacteria through agglutination in a calcium-dependent manner.

Summary: Horizontal gene transfer (HGT) is a significant evolutionary force that plays a crucial role in insect adaptation. In this study, we systematically analyzed 218 high-quality insect genomes and identified 1,410 genes acquired through HGT from non-metazoan donors. Lepidopterans had the highest number of HGT-acquired genes. Genes with introns showed higher expression levels, suggesting the involvement of intron gains in HGT adaptation. Additionally, we successfully edited a prevalent but previously unreported HGT-acquired gene in diamondback moths, which was found to affect courtship behavior.
