To investigate the adaptability of Hap3 and Hap17 <jats:italic>A. gossypii<\/jats:italic> to various <jats:italic>C. annuum<\/jats:italic> varieties, including \u2018Lvzhou101\u2019 (LZ), \u2018Lashen\u2019 (LA), \u2018Saierweilvtianjiao\u2019 (SE), \u2018Haimaihongri\u2019 (HM), \u2018Chaotianjiao\u2019 (CT), and \u2018Luosijiangjun\u2019 (LS), we employed life tables to analyse growth and population parameters post-feeding and conducted petri dish host choice experiments to assess the host plant preference of <jats:italic>A. gossypii<\/jats:italic>. Survival rates of <jats:italic>A. gossypii<\/jats:italic> varied significantly across <jats:italic>C. annuum<\/jats:italic> varieties. Notably, Hap3 and Hap17 thrived on \u2018LZ\u2019 but failed to establish populations on \u2018LA\u2019. The net reproductive rate (<jats:italic>R<\/jats:italic><jats:sub>0<\/jats:sub>), average generation time (<jats:italic>T<\/jats:italic>), and intrinsic rate of increase (<jats:italic>r<\/jats:italic><jats:sub>m<\/jats:sub>) differed markedly between Hap3 and Hap17 across <jats:italic>C. annuum<\/jats:italic> varieties. Feeding on \u2018LZ\u2019 resulted in a significantly higher <jats:italic>R<\/jats:italic><jats:sub>0<\/jats:sub> value (26.49) for Hap3 relative to other varieties. The <jats:italic>T<\/jats:italic> (7.60\u00a0days) and <jats:italic>r<\/jats:italic><jats:sub>m<\/jats:sub> (0.27) values for Hap3 on \u2018SE\u2019 were superior to those observed on other <jats:italic>C. annuum<\/jats:italic> varieties. These findings indicate that \u2018SE\u2019 is the optimal host for Hap3 growth, while \u2018LZ\u2019 best supports Hap17. Both haplotypes exhibited the lowest adaptability to \u2018LA\u2019. Therefore, the utilisation capacity of <jats:italic>A. gossypii<\/jats:italic> populations on <jats:italic>C. annuum<\/jats:italic> demonstrates differentiation, and the resistance levels among <jats:italic>C. annuum<\/jats:italic> varieties to <jats:italic>A. gossypii<\/jats:italic> vary. This differentiation can inform targeted management strategies for aphid infestations on pepper crops.<\/jats:p>","DOI":"10.1017\/s0007485325000100","type":"journal-article","created":{"date-parts":[[2025,3,21]],"date-time":"2025-03-21T10:56:18Z","timestamp":1742554578000},"page":"287-295","update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":3,"title":["Adaptability
