AI Article Synopsis
- - Juvenile hormone (JH) is crucial for controlling reproductive diapause in insects, but its specific effects on gene expression are not well understood at the transcriptome level.
- - In a new pest in Inner Mongolia, applying a JH analog, methoprene, before diapause delays the onset of diapause and affects lipid accumulation.
- - Analysis revealed significant changes in gene expression related to metabolism and reproductive functions, indicating that JH signaling significantly influences the reproductive diapause process in this pest.
Article Abstract
Juvenile hormone (JH) signaling plays an important role in regulation of reproductive diapause in insects. However, we have little understanding of the effect of JH on gene expression at the transcriptome level in diapause. is a new pest in the Inner Mongolia grasslands with obligatory summer diapause in the adult stage. Topical application of a JH analog methoprene at the pre-diapause stage delayed the adults entering diapause and inhibited lipid accumulation whereas it did not during diapause. Using Illumina sequencing technology and bioinformatics tools, 54 and 138 differentially expressed genes (DEGs) were detected at 1 and 2 d after treatment, respectively. The KEGG analysis showed that the DEGs were mainly enriched in the metabolism pathways. qRT-PCR analysis indicated that methoprene promoted the expression of genes encoding vitellogenin, fork head transcription factor and Krüppel homolog 1, whereas suppressed the expression of genes encoding juvenile hormone-binding protein, juvenile hormone esterase, juvenile hormone acid methyltransferase, juvenile hormone epoxide hydrolase and fatty acid synthase 2. These results indicate that JH signaling plays an important role in regulating reproductive diapause of .

Background: Juvenile hormone (JH) is a key endocrine governing insect development, metamorphosis and reproduction. JH analogs have offered great potential for insect pest control. In adulthood, JH titer rapidly increases in the previtellogenic period and reaches a peak in the vitellogenic phase.

Background: Nano(micro)plastics (NMPs) and agrochemicals are ubiquitous pollutants. The small size and physicochemical properties of NMPs make them potential carriers for pollutants, affecting their bioavailability and impact on living organisms. However, little is known about their interactions in terrestrial ecosystems.
