Both species inflict severe damage on the agricultural industry and international export trade. Their distribution range has expanded due to global warming, posing an increasing threat to fruit production. Heat shock proteins (HSPs), functioning as molecular chaperones, are known to contribute to temperature adaptation in insects. However, the cold adaptation regulatory mechanisms in these two Bactrocera species remain unclear. In this study, eIF4EBP3\u2212\/\u2212 mutations were established by the CRISPR-Cas9 system in both species. The survival rate of the mutations was significantly reduced with cold treatments, and qRT-PCR analysis indicated that eIF4EBP3 regulates the expression of several downstream heat shock proteins, suggesting that it may be involved in rapid cold hardening (RCH) adaptability in both fruit fly species. In addition, this work represents the first application of the CRISPR-Cas9 system in B. correcta, which provides methods to further studies on this species. Our results provide insights into the molecular mechanisms underlying rapid cold hardening adaptation in B. dorsalis and B. correcta and a potential molecular marker for monitoring cold tolerance in field populations which could guide the development of novel control strategies that target the RCH adaptation pathways.<\/jats:p>","DOI":"10.3390\/insects17080844","type":"journal-article","created":{"date-parts":[[2026,8,14]],"date-time":"2026-08-14T09:04:01Z","timestamp":1786698241000},"page":"844","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["The Gene Editing of Eukaryotic Translation Initiation Factor Binding Protein 3 and Its Potential Role in Rapid Cold Hardening of Two Invasive Fruit Flies"],"prefix":"10.3390","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-2086-9633","authenticated-orcid":false,"given":"Yuning","family":"Wang","sequence":"first","affiliation":[{"name":"State Key Laboratory of Agricultural and Forestry Biosecurity, College of Plant Protection, China Agricultural University, Beijing 100193, China"},{"name":"MARA Key Laboratory of Surveillance and Management for Plant Quarantine Pests, College of Plant Protection, China Agricultural University, Beijing 100193, China"},{"name":"Sanya Institute of China Agricultural University, Sanya 572025, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rihui","family":"Yan","sequence":"additional","affiliation":[{"name":"School of Tropical Agriculture and Forestry, Hainan University, Haikou 570228, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xianwu","family":"Lin","sequence":"additional","affiliation":[{"name":"School of Tropical Agriculture and Forestry, Hainan University, Haikou 570228, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Siya","family":"Ma","sequence":"additional","affiliation":[{"name":"School of Life and Health Sciences, Hainan University, Haikou 570228, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lijun","family":"Liu","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Agricultural and Forestry Biosecurity, College of Plant Protection, China Agricultural University, Beijing 100193, China"},{"name":"MARA Key Laboratory of Surveillance and Management for Plant Quarantine Pests, College of Plant Protection, China Agricultural University, Beijing 100193, China"},{"name":"Sanya Institute of China Agricultural University, Sanya 572025, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhihong","family":"Li","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Agricultural and Forestry Biosecurity, College of Plant Protection, China Agricultural University, Beijing 100193, China"},{"name":"MARA Key Laboratory of Surveillance and Management for Plant Quarantine Pests, College of Plant Protection, China Agricultural University, Beijing 100193, China"},{"name":"Sanya Institute of China Agricultural University, Sanya 572025, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,8,14]]},"reference":[{"key":"ref_1","first-page":"1","article-title":"Progress of invasion prevention and control technologies of solid fly pests","volume":"2","author":"Li","year":"2013","journal-title":"Plant Quar."},{"key":"ref_2","doi-asserted-by":"crossref","unstructured":"White, I.M., and Elson-Harris, M.M.
