AI Technical Summary

Technical Problem

Existing chemical pesticides cause ecological pollution and increase pesticide resistance in the control of brown planthoppers. There is a lack of environmentally friendly and efficient pest control methods, and there are no reports on the application of rice-derived miRNAs in the control of brown planthoppers.

Method used

The rice-derived miRNA Osa-miR160e-3p and its mimics are used to enhance their function through chemical synthesis. These mimics are then used to prepare insecticides or transgenic plants, which are then sprayed or injected directly into pests to interfere with their growth, development, and reproduction.

Benefits of technology

It significantly reduces the survival rate and molting success rate of brown planthopper nymphs, providing a safe and effective pest control method and reducing the use of chemical pesticides.

Abstract

This invention belongs to the field of pest control technology and discloses the application of Osa-miR160e-3p in the control of brown planthoppers, specifically its application in pest control and / or the preparation of pest control products. This invention is the first to discover that injecting brown planthoppers with artificially synthesized Osa-miR160e-3p mimics significantly reduces the survival rate of brown planthopper nymphs compared to the control group injected with DEPC water, proving that Osa-miR160e-3p can be used for the control of brown planthoppers. Therefore, Osa-miR160e-3p can be directly used for field spraying and in transgenic plants, demonstrating good application value.
