Abstract：
microRNAs
(miRNAs) are endogenous, single-stranded non-coding RNAs of about 22
nucleotides in length. They regulate gene expression post-transcriptionally by
base pairing with complementary seed sequences (2nd to 8th nucleotides at the
5' end of miRNAs) in the 3' untranslated region (UTR) of mRNA. In insects,
miRNAs have been shown to regulate a variety of physiological processes
including metamorphosis, oogenesis, behavior, and host-pathogen interactions
during development. In recent years, research on the function of miRNAs in
important agricultural insects has attracted widespread attention. Based on a
brief introduction of miRNA biosynthesis and their mechanism of action, this
paper focuses on recent progress in research on the role of miRNAs in insect
reproduction and wing development with the aim of improving the understanding
of insect miRNAs and promoting their application in pest control.
