Smith) (Lepidoptera: Noctuidae), is a devastating pest of maize, and host plant resistance offers a sustainable alternative to chemical control. This study evaluated the resistance of the maize germplasm CH1 against FAW through life table parameters, feeding and oviposition preferences and greenhouse experiment. Results showed that FAW larvae reared on CH1 exhibited significantly prolonged larval development (21.61 d vs. 12.49 d), reduced survival (65.00% vs. 94.00%), and lower fecundity (689.00 vs. 1369.93 eggs per female) compared to those on the susceptible control Huang C. Population parameters, including the intrinsic rate of increase (r) and net reproductive rate (R0), were significantly lower on CH1. Behavioral assays revealed strong feeding and oviposition preferences for Huang C over CH1. Greenhouse experiment confirmed that CH1 plants sustained only minor damage (Davis scale grade 2, resistant), whereas Huang C plants were severely damaged (grade 7, susceptible). These findings demonstrate that CH1 possesses multi-dimensional resistance against FAW, providing a promising genetic resource for breeding FAW-resistant maize varieties and supporting sustainable pest management strategies.<\/jats:p>","DOI":"10.3390\/insects17090897","type":"journal-article","created":{"date-parts":[[2026,8,27]],"date-time":"2026-08-27T09:00:35Z","timestamp":1787821235000},"page":"897","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["A Maize Germplasm Is Resistant to Fall Armyworm: From Life Table Analysis to Greenhouse Assays"],"prefix":"10.3390","volume":"17","author":[{"given":"Lingling","family":"Li","sequence":"first","affiliation":[{"name":"Institute of Plant Protection, Guizhou Academy of Agricultural Sciences, Guiyang 550006, China"},{"name":"Guizhou Key Laboratory of Agricultural Biosecurity, Guiyang 550006, China"},{"name":"Guizhou Branch of State Key Laboratory for Biology of Plant Diseases and Insect Pests, Guiyang 550006, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peiying","family":"Li","sequence":"additional","affiliation":[{"name":"Institute of Plant Protection, Guizhou Academy of Agricultural Sciences, Guiyang 550006, China"},{"name":"Guizhou Key Laboratory of Agricultural Biosecurity, Guiyang 550006, China"},{"name":"Guizhou Branch of State Key Laboratory for Biology of Plant Diseases and Insect Pests, Guiyang 550006, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-6011-6144","authenticated-orcid":false,"given":"Wenmeng","family":"Li","sequence":"additional","affiliation":[{"name":"Institute of Plant Protection, Guizhou Academy of Agricultural Sciences, Guiyang 550006, China"},{"name":"Key Laboratory of Forest Disaster Warning and Control in Yunnan Province, College of Forestry, Southwest Forestry University, Kunming 650224, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Changgeng","family":"Dai","sequence":"additional","affiliation":[{"name":"Institute of Plant Protection, Guizhou Academy of Agricultural Sciences, Guiyang 550006, China"},{"name":"Guizhou Key Laboratory of Agricultural Biosecurity, Guiyang 550006, China"},{"name":"Guizhou Branch of State Key Laboratory for Biology of Plant Diseases and Insect Pests, Guiyang 550006, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hongbo","family":"Li","sequence":"additional","affiliation":[{"name":"Institute of Plant Protection, Guizhou Academy of Agricultural Sciences, Guiyang 550006, China"},{"name":"Guizhou Key Laboratory of Agricultural Biosecurity, Guiyang 550006, China"},{"name":"Guizhou Branch of State Key Laboratory for Biology of Plant Diseases and Insect Pests, Guiyang 550006, China"},{"name":"Key Laboratory of Crop Genetic Resources and Germplasm Innovation in Karst Region, Ministry of Agriculture and Rural Affairs, Guiyang 550006, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,8,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1295","DOI":"10.1007\/s12571-022-01288-7","article-title":"Global Maize Production, Consumption and Trade: Trends and R & D Implications","volume":"14","author":"Erenstein","year":"2022","journal-title":"Food Secur."},{"key":"ref_2","unstructured":"FAO (2024).
