guianense has wide geographical distribution and some populations are zoophilic whereas others are anthropophilic
, it is suspected that the species is a complex of 2 or more sibling species (i.
Aedes vittatus appears to be playing no role in dengue transmission in these areas because of its poor anthropophilic
nature and no isolation of virus from a very few adult specimens obtained in the field.
Research into the host preferences of identified SBV vector species and, if proven anthropophilic
, their feeding rates could clarify this issue.
Although it is possible that this pattern is due, at least in part, to sampling error (diseases associated with anthropophilic
species would be the first to come to our attention), the pattern could be the logical consequence of several characteristics of opportunistic species (high vagility, rapid growth, early reproduction, high fecundity, and capacity to sustain high population densities that are conducive to the transmission of pathogens) that would facilitate the evolution and maintenance of pathogens.
aegypti is an anthropophilic
mosquito, which has evolved intimate relationship with humans and exhibits several behavioural traits like oviposition in man-made and man-used natural and artificial containers (3).
Both the species are attracted to shady places but the former is highly anthropophilic
preferring urbanized habitats while the latter is more zoophilic that lives in woody rural habitats around residences (8).
We tested anthropophilic
mosquitoes for the presence of R.
On the anthropophilic

data), although feeding patterns of these mosquitoes are zoonotic rather than anthropophilic
in certain areas (32).
Silent transmission of dengue viruses in rural areas has been shown in Tamil Nadu, where circulation of all four dengue virus serotypes were detected during transmission season with a high anthropophilic
index of vectors and high abundance of vectors but no apparent DF cases were reported (10).
In many foci of VL, there is at least one species of sandfly that is common and anthropophilic
to be considered as a probable vector, although good evidence to support this belief is lacking, such as the detection in wild caught females of this species and the parasites causing the VL.
albopictus mosquitoes are also potential DENV vectors in Africa where they are considered more anthropophilic
