摘要： Helicoverpa armigera, cotton bollworm, is one of the most disastrous pests worldwide, threatening various food and economic crops. Functional genomic tools may provide efficient approaches for its management. The clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein 9 (Cas9) system, dependent on a single guide RNA (sgRNA), has been used to induce indels for targeted mutagenesis in cotton bollworm. However, genomic deletions may be more desirable to disrupt the function of noncoding genes or regulatory sequences. By injecting two sgRNAs with Cas9 protein targeting different exons, we obtained predictable genomic deletions of several hundred bases. We achieved this type of modification with different combinations of sgRNA pairs, including HaCad and HaABCC2. Our finding indicated that CRISPR/Cas9 can be used as an efficient tool to engineer genomes with chromosomal deletion in H. armigera.
