The objective of this work was to evaluate the potential for using Landsat-8 images, with medium spatial resolution and distributed free of charge, to detect leaf-cutting ant nests in Tectona grandis plantations in Brazil, using partial least squares discriminant analysis (PLS-DA). The regression model adjusted by PLS-DA selected three principal components with a cross-validation error of 0.275 to map and predict the presence of leaf-cutting ant nests in these plantations. The most important bands and vegetation indices were selected using the main variables in the projection (VIP) and predicted pixels with the presence or absence of leaf-cutting ant nests with an accuracy of 72.3% on an independent validation data set. The study indicates that Landsat-8 OLI images have the potential to detect and map leaf-cutting ant nests in T. grandis plantations.<\/jats:p>","DOI":"10.3390\/rs11141641","type":"journal-article","created":{"date-parts":[[2019,7,10]],"date-time":"2019-07-10T11:56:51Z","timestamp":1562759811000},"page":"1641","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Remote Sensing to Detect Nests of the Leaf-Cutting Ant Atta sexdens (Hymenoptera: Formicidae) in Teak Plantations"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6810-6272","authenticated-orcid":false,"given":"Isabel Carolina de Lima","family":"Santos","sequence":"first","affiliation":[{"name":"Laborat\u00f3rio de Fitossanidade (FitLab), Instituto Federal de Mato Grosso\u2014IFMT, Caixa Postal 244, 78200-000 C\u00e1ceres, Mato Grosso, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8232-6722","authenticated-orcid":false,"given":"Alexandre dos","family":"Santos","sequence":"additional","affiliation":[{"name":"Laborat\u00f3rio de Fitossanidade (FitLab), Instituto Federal de Mato Grosso\u2014IFMT, Caixa Postal 244, 78200-000 C\u00e1ceres, Mato Grosso, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zakariyyaa","family":"Oumar","sequence":"additional","affiliation":[{"name":"University of Witwatersrand, School of Geography, Archaeology and Environmental Studies, Private Bag 3, Witwatersrand 2050, South Africa"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8725-3697","authenticated-orcid":false,"given":"Marcus Alvarenga","family":"Soares","sequence":"additional","affiliation":[{"name":"Programa de P\u00f3s-Gradua\u00e7\u00e3o em Produ\u00e7\u00e3o Vegetal, Universidade Federal dos Vales Jequitinhonha e Mucuri (UFVJM), 39100-000 Diamantina, Minas Gerais, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J\u00falius C\u00e9sar Cerqueira","family":"Silva","sequence":"additional","affiliation":[{"name":"Departamento de Entomologia, Universidade Federal de Lavras, Caixa Postal 3037, 37200-000 Lavras, Minas Gerais, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ronald","family":"Zanetti","sequence":"additional","affiliation":[{"name":"Departamento de Entomologia, Universidade Federal de Lavras, Caixa Postal 3037, 37200-000 Lavras, Minas Gerais, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jos\u00e9 Cola","family":"Zanuncio","sequence":"additional","affiliation":[{"name":"Departamento de Entomologia BIOAGRO, Universidade Federal de Vi\u00e7osa, 36570-900 Vi\u00e7osa, Minas Gerais, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,7,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"422","DOI":"10.1007\/s00267-017-0884-6","article-title":"Climatic-induced shifts in the distribution of teak (Tectona grandis) in Tropical Asia: Implications for forest management and planning","volume":"60","author":"Deb","year":"2017","journal-title":"Environ.
