Latin American Student Competition I

Latin American Student Competition I

89 - Detritus and larval interspecific competition on female Aedes aegypti phenotypic traits, nutrient profile, and DENV-1 vector competence

Wednesday, March 5, 2025
8:50 AM – 9:00 AM AST
Location: 202
Abstract: Larval environment can influence phenotypic traits of adult mosquito vectors and possibly, their arbovirus vector competence. Laboratory experiments showed that detritus and larval density influenced female Aedes aegypti survival, development time, wing length, nutrient profile, and dengue vector competence. Low density-low detritus females had lower DENV-1 vector competence, while high density-intermediate detritus females had higher. We show how environmental changes influence Ae. aegypti and its potential to transmit dengue, an important arbovirus affecting human health.
