Description
Abstract
En el presente estudio se analiza la amplitud del nicho ecológico
de Aedes aegypti (Diptera, Culicidae), el principal transmisor del virus
del dengue en la región de las Américas, a fin de entender los
mecanismos básicos de su actual distribución espacial en un área
de Camagüey, Cuba. Se calculó el Índice Recipiente específico
(IRe) por tipo de depósitos positivos, así como la correlación entre
el total de focos y los depósitos permanentes y útiles positivos/mes
mediante la correlación no paramétrica de Spearman (R=0,93;
p<0,001). Esta especie es la más frecuente y abundante en los recipientes
artificiales, con un alto nivel de exclusividad. Los depósitos
permanentes y útiles deben tener la primacía en la ejecución
de las intervenciones de vigilancia y control larvario.
ABSTRACT: The ecological niche width of Aedes aegypti (Diptera, Culicidae), the main vector of dengue virus in the Region of the Americas, was studied in order to understand the basic mechanisms of its current spatial distribution in an area of Camagüey, Cuba. The specific container index (SCI) was calculated and the association between the monthly values of total of breeding sites and the total of both kind of receptacles (habitual-use and non-disposable) was evaluated by means of the nonparametric Spearman’s correlation index (R=0,93; p<0,001). This mosquito was the dominant species in regard to the whole set of water reservoirs by reaching a noticeable level of exclusivity. Habitual-use and non-disposable containers should receive top priority regarding the application of larval surveillance and control interventions.
