Anopheles darlingi Root, a dominant vector species for malaria in Central and South America, has a broad distribution spanning from southern Mexico to northernArgentina and from the eastern side of the Andes Mountains to the Atlantic and Caribbean Coastline. It has not been reported in Nicaragua or Costa Rica. Variability in genetics, morphology and behavior has been reported across its range. It has been suggested that An. darlingi is a cryptic species. A deep divergence, detected by the nuclear white gene, separates the species into a northern lineage Belize, Guatemala, Colombia, Venezuela and Panama and a southern lineage Amazonia and southern Brazil. It is unknown if these lineages confer differences to epidemiologically relevant behaviors. Variation in study methodologies do not allow for direct comparison of behavior across the range of An. darlingi. The objectives of this research were to compare l house entry, house exit, and host preference behavior and 2 wing morphology between field populations of An. darlingi representing the two genotypes using a standard methodology that can allow for a statistical comparison.
