Previous studies under 1 environment in Cameroon, Central Africa, had found multiple okra genotypes with resistance to A. gossypii. However, the stability and yield performance of the \u201cresistant\u201d genotypes across different environments were unknown. Ten previously identified aphid-resistant okra genotypes along with 1 commercial variety and a local landrace (specific to a given location) were compared during 2 seasons in replicated trials in 4 agro-ecological zones of Cameroon that also represent large areas of Central Africa. Aphid populations and okra yield parameters were evaluated. Breeding values were predicted using a linear mixed model for all data, and genotypes by location interactions were identified. The area under the infestation pressure curve (AUIPC) was calculated using aphid count data and subjected to resistance analysis. The Local\u2014the most susceptible with the highest breeding value (+2.33)\u2014and VI060794\u2014one of the moderately resistant\u2014genotypes had the highest yield per hectare. The only resistant genotype VI036213 had the lowest breeding value (\u20132.20). Genotype\u2005\u00d7\u2005location interactions were significant for yield, pod width, and plant height, while location variance was significant for all parameters evaluated. When considering that higher aphid densities could lead to greater pesticide use and, therefore higher production and environmental costs, the high-yielding VI060794\u2014with moderate aphid resistance across multiple environments\u2014presents an alternative or substitute for local landraces across multiple agro-ecologies of Cameroon and (by extension) Central Africa.<\/jats:p>","DOI":"10.1093\/jee\/toae165","type":"journal-article","created":{"date-parts":[[2024,7,5]],"date-time":"2024-07-05T16:39:42Z","timestamp":1720197582000},"page":"2123-2134","source":"Crossref","is-referenced-by-count":3,"title":["New okra genotypes for the management of aphids (Hemiptera: Aphididae) in the diverse ecological landscapes of Central Africa"],"prefix":"10.1093","volume":"117","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2791-9557","authenticated-orcid":false,"given":"Albert Fomumbod","family":"Abang","sequence":"first","affiliation":[{"name":"International Institute of Tropical Agriculture (IITA) Yaound\u00e9 , Yaound\u00e9 ,","place":["Cameroon"]},{"name":"World Vegetable Center (AVRDC) , Shanhua, Tainan ,","place":["Taiwan"]},{"name":"Department of Animals Biology and Physiology, Faculty of Science, University of Yaound\u00e9 I , Yaound\u00e9 ,","place":["Cameroon"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8454-7331","authenticated-orcid":false,"given":"Srinivasan","family":"Ramasamy","sequence":"additional","affiliation":[{"name":"World Vegetable Center (AVRDC) , Shanhua, Tainan ,","place":["Taiwan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5715-0144","authenticated-orcid":false,"given":"Rachid","family":"Hanna","sequence":"additional","affiliation":[{"name":"International Institute of Tropical Agriculture (IITA) Yaound\u00e9 , Yaound\u00e9 ,","place":["Cameroon"]},{"name":"Center for Tropical Research, Institute of the Environment and Sustainability, University of California, Los Angeles , Los Angeles, CA ,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9058-100X","authenticated-orcid":false,"given":"Sevillor","family":"Kekeunou","sequence":"additional","affiliation":[{"name":"Department of Animals Biology and Physiology, Faculty of Science, University of Yaound\u00e9 I , Yaound\u00e9 ,","place":["Cameroon"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5247-7519","authenticated-orcid":false,"given":"Apollin","family":"Fotso Kuate","sequence":"additional","affiliation":[{"name":"International Institute of Tropical Agriculture (IITA) Yaound\u00e9 , Yaound\u00e9 ,","place":["Cameroon"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3037-2644","authenticated-orcid":false,"given":"Abdou","family":"Tenkouano","sequence":"additional","affiliation":[{"name":"International Center of Insect Physiology and Ecology (icipe) , Nairobi ,","place":["Kenya"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5113-2159","authenticated-orcid":false,"given":"Komi Kouma Mokpokpo","family":"Fiaboe","sequence":"additional","affiliation":[{"name":"International Institute of Tropical Agriculture (IITA) Yaound\u00e9 , Yaound\u00e9 ,","place":["Cameroon"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0138-5718","authenticated-orcid":false,"given":"Charles-F\u00e9lix","family":"Bilong Bilong","sequence":"additional","affiliation":[{"name":"Department of Animals Biology and Physiology, Faculty of Science, University of Yaound\u00e9 I , Yaound\u00e9 ,","place":["Cameroon"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2024,7,29]]},"reference":[{"issue":"3","key":"2024101420414871900_CIT0001","doi-asserted-by":"crossref","first-page":"240","DOI":"10.1080\/19315260.2013.800625","article-title":"Assessing vegetable farmer knowledge of diseases and insect pests of vegetable and management practices under tropical conditions","volume":"20","author":"Abang","year":"2014","journal-title":"Int.
