However, its function in the growth, development and morphogenesis of Gryllus bimaculatus remains poorly understood. This study aimed to explore the function of the Scr gene in G. bimaculatus by using CRISPR/Cas9 technology to generate an Scr gene knock-out strain. Intercrossing the G₀ generation knock-out individuals with wild-type individuals yielded the G₁ generation to screen the mutant strain. It was found that the knock-out of the Scr gene had a severe impact on the growth and development of G. bimaculatus, resulting in high mortality and making it difficult to obtain Scr^-/- mutants. Therefore, heterozygous individuals (Scr^+/-) with 1 bp deleted were obtained for investigation. The results showed that the Scr deletion led to ectopic segment formation in the G₀ generation. In the G₂ generation, it was observed that stable Scr^-/- strains displayed abnormal embryonic development, characterized by enlarged, blackened and lethal eggs during embryogenesis. During the post-embryonic stage, Scr^-/- mutants exhibited abnormalities in body segmentation, particularly in the head-thorax region, resulting in a dorsal ridge structure. Furthermore, some Scr^+/- individuals exhibited a dorsal ridge during the nymphal stage. Notably, this characteristic did not persist into the adult stage. Our findings highlight the distinct but crucial roles of the Scr gene in both embryonic and post-embryonic growth and development of G. bimaculatus.</p>","PeriodicalId":13526,"journal":{"name":"Insect Molecular Biology","volume":" ","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143482892","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As with all pesticides, appropriate insect resistance management (IRM) programmes are required to mitigate the selection for resistance in target insect populations and extend product durability in the field. IRM programmes for RNAi products follow the same guidelines that currently exist for insecticidal traits or conventional insecticidal sprays. These guidelines reflect the distinct exposure scenarios for traits versus sprays, that is, continuous exposure when dsRNA is expressed in the crop compared to intermittent exposure when sprayed on foliage. As such, IRM plans for dsRNA traits depend on pyramiding (stacking) non-cross-resistant traits along with a refuge of non-transgenic plants.

The current study examines the effect of synthetic insecticides on the gut microbiome of third instar S. frugiperda larvae using both culture-dependent techniques and 16S rRNA gene sequencing for bacterial community profiling and diversity analysis. In untreated larvae, the sequencing approach revealed a diverse microbiome dominated by the phyla Firmicutes, Proteobacteria and Bacteroidota, with key genera including Bacteroides, Faecalibacterium and Pelomonas. In parallel, 323 bacterial strains were isolated and assigned to the orders Bacillales, Burkholderiales, Enterobacterales, Flavobacteriales, Lactobacillales, Micrococcales, Neisseriaies, Pseudomonadales, Sphingobacteriales and Xanthomonadales. The prevailing culturable species included Serratia marcescens, Klebsiella variicola and Enterobacter quasiroggenkampii. Treatment with sublethal concentrations of three insecticides (broflanilide, spinosad and indoxacarb) caused significant changes in gut microbiome diversity and composition. Treated larvae showed a shift towards increased Proteobacteria abundance and decreased Firmicutes. Specifically, Acinetobacter and Rhodococcus were dominant in treated samples. Functional predictions highlighted significant metabolic versatility involving nutrient processing, immune response, detoxification, xenobiotic metabolism, and stress response, suggesting microbial adaptation to insecticide exposure. Network correlation analysis highlighted disrupted microbial interactions and altered community structures under insecticide treatment.

This study examined the effects of autophagy-related genes Atg3, Atg5 and Atg12 on apoptosis and autophagy during the degeneration of the posterior silk gland in Bombyx mori, employing RNA interference techniques. Apoptosis-specific markers and autophagic processes were evaluated in both control and treatment groups. The knockdown of all three genes resulted in a significant reduction in autophagy, modifications in the apoptosis process, aberrant expression of p53 and impaired lysosomal function. It was determined that Atg3 is involved in the regulation of intracellular mitochondrial homeostasis. Following the silencing of Atg5, evidence was obtained indicating the gene's role in regulating lysosomal pH. Notably, the loss of Atg3 and Atg5 was associated with an increase in apoptotic markers, whereas the silencing of Atg12 inhibited apoptosis. Elevated levels of the p53 transcription factor following gene silencing suggested a potential interaction between these genes and p53. Our findings further underscore the importance of autophagy-mediated cell death, involving Atg3, Atg5 and Atg12, in the proper progression of degeneration in the posterior silk gland.

Insect sex determination pathways are comprised of primary signals, relay genes and terminal genes. Primary signals of coleopteran, dipteran, hymenopteran and lepidopteran species are highly diverse and regulate the sex-specific splicing of relay genes based on the primary signal dosage, amino acid composition or the interaction with paternally inherited genes. In coleopterans, hymenopterans and some dipterans, relay genes are Transformer orthologs from the serine-arginine protein family that regulate sex-specific splicing of the terminal genes. Alternative genes regulate the splicing of the terminal genes in dipterans that lack Transformer orthologs and lepidopterans. Doublesex and Fruitless orthologs are the terminal genes. Doublesex and Fruitless orthologs are highly conserved zinc-finger proteins that regulate the expression of downstream proteins influencing physical traits and courtship behaviours in a sex-specific manner. Genetic pest management methods can use different mechanisms to exploit or disrupt female-specific regions of different sex determination genes. Female-specific regions of sex determination genes can be exploited to produce a lethal gene only in females or disrupted to impede female development or fertility. Reducing the number of fertile females in pest populations creates a male-biased sex ratio and eventually leads to the local elimination of the pest population.

The results indicated that the body weight of silkworms decreased, along with damage to the morphology of their digestive tracts and midguts after starvation treatment. Additionally, mitochondrial swelling, autophagy and apoptosis were observable. Further investigation revealed that starvation upregulated the transcription of Ca²⁺ release channel-associated genes (e.g., BmIP3R, BmRyR) but suppressed the expression of Ca²⁺ efflux genes (BmPMCA), resulting in Ca²⁺ overload in midgut cells and subsequent upregulation of BmCalpain transcription. In addition, starvation increased the transcription of key autophagy genes (BmATG5, BmATG7, BmATG8) and the expression of the LC3-II protein. Upon prolonged starvation, the NtATG5 protein levels increased, a process that facilitated the transition from autophagy to apoptosis. These results indicate that Ca²⁺ overload activates the calpain-mediated apoptosis pathway and promotes apoptosis of midgut cells.

In the present study, the AKH was identified from Panonychus citri and contained the conserved functional domain 'Q-[LIV]-[NT]-F-[ST]-X (2)-W' that characterises the AKH family. The relative expression levels of PcAKH revealed different patterns of AKH expression at different developmental stages of P. citri. Feeding of double-standard RNA against PcAKH induced decreased fecundity and reduced survival, which was accompanied by the down-regulation of vitellogenin gene expression. In addition, after silencing the PcAKH, lipid metabolism and carbohydrate homeostasis were disrupted, manifested by increased body width and weight, and fasting phenomenon. Further investigation found that compared with the control, physiological changes in trehalose and triglyceride contents were accompanied by variations in the mRNA expression levels of genes related to lipid metabolism and carbohydrate metabolism. The disorder of lipid and carbohydrate metabolism may affect adult female reproduction, which may lead to insufficient vitellogenin deposition. Moreover, the silencing of PcAKH seriously affected the growth and development of larvae, which was manifested as delayed development period and difficulty in moulting.
