Alternative splicing ultimately plays a role in increasing the diversity of the proteome through increasing transcriptome diversity. Here, we characterized various novel <em>CYP9A19</em> isoforms in <em>Bombyx mori</em>. We first identified an exon 4 deletion isoform that was 203 bp smaller than expected due to a deletion of exon 4 from the protein coding sequence (CDS) region of the <em>CYP9A19</em> cDNA. Within the <em>CYP9A19</em> cDNA, there is a 176 bp 5′-untranslated region (UTR); reverse transcription-polymerase chain reaction results showed 74 bp lower and 122 bp higher molecular-weight products compared with the expected size from the 5′-UTR of <em>CYP9A19</em> cDNA in <em>B. mori</em>. Additionally, we found a new sequence (5′-GTCTCAGGTTCAGGGCTCTAGCAATTTTTCACAG-3′) in the 5′-UTR of <em>CYP9A19</em>. Currently, our understanding of the various <em>CYP9A19</em> isoform functions in pesticide degradation and resistance and insect development and differentiation stages remains limited. Therefore, additional studies on the alternative splicing process are needed to verify the biological role of the novel splicing variant of <em>CYP9A19</em> in <em>B. mori</em>.

The complete mitochondrial genomes of <em>Motaga mengyangensis</em>, <em>Motaga acicularis</em>, <em>Tautoneura albida</em>, and <em>Tautoneura unicolor</em>, which belong to the tribe Erythroneurini from China, were sequenced for the first time. The lengths of the complete mitogenomes of these four species ranged from 15,361 to 15,856 base pairs, and a typical set of 37 genes was identified in each. Among the 13 protein-coding genes (PCGs), except for the <em>atp8</em> gene in <em>T. albida and T. unicolor</em>, which started with the codon TTG, the remaining genes all began with typical ATN codons (ATA/ATT/ATC/ATG). The stop codons were TAA, TAG, or an incomplete stop codon T. Utilizing three datasets from the mitochondrial genomes (PCGs, PCGsrRNA, and PCGs12rRNA) of 36 species (including two outgroups), phylogenetic trees of Erythroneurini were constructed via maximum likelihood and Bayesian inference methods. The results revealed that all phylogenetic trees supported the clustering of <em>M. mengyangensis</em> and <em>M. acicularis</em> into one evolutionary branch, as well as the clustering of <em>T. albida</em> and <em>T. unicolor</em> into another. Furthermore, all the results consistently supported the monophyly of genera within Erythroneurini and uniformly demonstrated that the genus <em>Motaga</em> formed a sister group relationship with the genus <em>Empoascanara</em>.

Currently, this task mainly relies on manual counting, which poses many challenges such as high workload, low efficiency, and being error-prone. To alleviate these problems, this study proposes a deep learning-based method for silkworm egg counting. Images of silkworm eggs were captured from actual environments and annotated using a labeling tool, resulting in more than 300,000 labeled eggs. A counting network based on the You Only Look Once (YOLOv8n) object detection network is proposed, in which an efficient multi-scale attention (EMA) module is embedded in the extraction block of the original network to enhance feature representation capability and suppress interference. To further improve counting performance, a space-to-depth convolution (SPD-Conv) block is introduced to replace the down-sample layer implemented by convolutional layers with a stride of 2. The proposed network is termed YOLO for silkworm egg counting (YOLO-SEC). Experimental results demonstrate that our YOLO-SEC achieves a recall of 99.50 %, a precision of 98.29 %, an F1-score of 0.99, and an AP of 99.31 % for silkworm eggs on the test set. Meanwhile, YOLO-SEC shows significant performance advantages over the original YOLOv8 (n ∼ x), state-of-the-art networks (YOLOv7-tiny, YOLOv9s, YOLOv10n and YOLOv11n), and related networks (YOLOv8-QR, EDGC-YOLO, Faster-YOLO-AP, YOLOv8-ECFS).

The results of demographic analysis suggested that the differences in genetic structure of <em>T. hawaiiensis</em> from different host plants are not obvious, and genetic changes may be related to pesticide stres.
