Abstract
Genomic approaches, such as RNA interference (RNAi) and CRISPR/Cas9, have shown promise for insect pest management. RNAi techniques involve the use of double-stranded RNAs (dsRNA) to silence specific target genes in arthropod pests, which can be highly selective and safe for non-target organisms. CRISPR/Cas9 technology, on the other hand, allows for precise editing of insect genomes, offering potential strategies for controlling pests through various mechanisms such as impairing reproductive capacity or making pests susceptible to insecticides. These genomic approaches provide species-specific and environmentally friendly alternatives to chemical insecticides, which are facing challenges such as resistance and negative impacts on human health and the environment. However, there are still challenges to overcome, such as the delivery of genetic material into the germline of insects, particularly in the Hemiptera order. Further research and advancements in these genomic technologies are needed to fully realize their potential for insect pest management.
