Several studies suggest that an increased density of\n                    <jats:italic>Aedes aegypti<\/jats:italic>\n                    and the presence of dengue cases may be associated with climatic conditions. This study aimed to establish the phenotypic variations of\n                    <jats:italic>Ae. aegypti<\/jats:italic>\n                    from four cities (Asunci\u00f3n, Itaugu\u00e1, Minga Guaz\u00fa, and Ciudad del Este) and the potential association of environmental variables with the number of eggs in capture sites. Eleven morphometric phenotypic characters were evaluated, and environmental data were obtained from Earth Engine and local meteorological stations. An analysis was carried out using principal component analysis and linear discriminant analysis, and we estimated the correlation using [relative humidity, Normalized Difference Vegetation Index (NDVI) and Normalized Difference Water Index (NDWI)] between variables and the number of eggs in each site. Differences in mean NDVI and NDWI between cities and their relationship with the morphometric performance of individuals were also assessed. The study demonstrated morphometric variations between the populations of\n                    <jats:italic>Ae. aegypti<\/jats:italic>\n                    from two ecoregions, with the Litoral ecoregion populations presented a greater phenotypic variation than those observed in the Alto Paran\u00e1 ecoregion. Significant statistical associations were registered between the number of eggs with relative humidity (\n                    <jats:italic>r<\/jats:italic>\n                    = \u20130.45) and the NDVI at 100 meters from the capture points (\n                    <jats:italic>r<\/jats:italic>\n                    = \u20130.61) for Minga Guaz\u00fa, and with the NDWI at 100 meters (\n                    <jats:italic>r<\/jats:italic>\n                    = 0.54) for Ciudad del Este. Future studies on these\n                    <jats:italic>Ae. aegypti<\/jats:italic>\n                    populations, and its dispersion could contribute to improve vector control measures and foster future genetic studies.\n                  <\/jats:p>","DOI":"10.4269\/ajtmh.21-1184","type":"journal-article","created":{"date-parts":[[2022,6,20]],"date-time":"2022-06-20T08:45:19Z","timestamp":1655714719000},"page":"300-307","source":"Crossref","is-referenced-by-count":3,"title":["Phenotypic Variations of Aedes aegypti Populations and Egg Abundance According to Environmental Parameters in Two Dengue-Endemic Ecoregions in Paraguay"],"prefix":"10.4269","volume":"107","author":[{"given":"Milena Beatriz","family":"Britos Molinas","sequence":"first","affiliation":[{"name":"Centro para el Desarrollo de la Investigaci\u00f3n Cient\u00edfica, Asunci\u00f3n, Paraguay;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elvio","family":"Gayozo Melgarejo","sequence":"additional","affiliation":[{"name":"Universidad Nacional de Asunci\u00f3n, Facultad de Ciencias Exactas y Naturales, Departamento de Biolog\u00eda, Laboratorio de Mutag\u00e9nesis, Carcinog\u00e9nesis y Teratog\u00e9nesis Ambiental, San Lorenzo, Paraguay"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Antonieta","family":"Rojas de Arias","sequence":"additional","affiliation":[{"name":"Centro para el Desarrollo de la Investigaci\u00f3n Cient\u00edfica, Asunci\u00f3n, Paraguay;"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2795","reference":[{"key":"b1","series-title":"Infect Genet Evol","first-page":"11","article-title":"Heritability and adaptive phenotypic plasticity of adult body size in the mosquito Aedes aegypti with implications for dengue vector competence","volume":"11","author":"Schneider","year":"2011"},{"key":"b2","series-title":"Funda\u00e7\u00e3o Oswaldo Cruz","first-page":"625","article-title":"Estructura gen\u00e9tica poblacional del mosquito del dengue Aedes aegypti en Venezuela.
