To find suitable targets for disruption of its reproduction, we observed the testis and ovary development of <i>H. armigera</i> and conducted deep sequencing of the ovary and testis small RNAs of <i>H. armigera</i> and quantitative RT-PCR (RT-qPCR) validation to identify reproduction-related micro RNAs (miRNAs).

Many of these target transcripts are assigned to reproduction-related GO terms (e.g., oocyte maturation, vitellogenesis, spermatogenesis) and are members of multiple reproduction-related KEGG pathways, such as the JAK-STAT signaling pathway, oocyte meiosis, the insulin signaling pathway, and insect hormone biosynthesis. These results suggest that the 8 gonad-biased miRNAs play important roles in reproduction and may be used as the targets for the development of reproductive-destruction-based control of <i>H. armigera</i> and, possibly, other lepidopteran pests.https://www.mdpi.com/2075-4450/12/8/749miRNAspiRNAsovarytestisreproductive destructiondevelopment |

The high fecundity of the most destructive pest <i>Helicoverpa armigera</i> and its great resistance risk to insecticides and Bt crops make the reproductive-destruction-based control of this pest extremely appealing. To find suitable targets for disruption of its reproduction, we observed the testis and ovary development of <i>H. armigera</i> and conducted deep sequencing of the ovary and testis small RNAs of <i>H. armigera</i> and quantitative RT-PCR (RT-qPCR) validation to identify reproduction-related micro RNAs (miRNAs).
