 en Anopheles aquasalis eggs from two Venezuelan localities compared by scanning electron microscopy
V Maldonado; HJ Finol & JC Navarro


Anopheles (Nyssorhynchus) aquasalis, is the main coastal vector of malaria
from northeastern Venezuela to southeastern Brazil. Several authors have
argued that An. aquasalis is a highly polymorphic species while others
indicited that it is a complex of closely related species. This
investigation compared the morphology of An. aquasalis eggs from Sinamaica
(Zulia State) and Yaguaraparo (Sucre State), the west and east of
Venezuela, respectively. We were able to separate eggs from the two
localities using discriminant analyses based on ratios and percentages of
anterior and posterior tubercles measured by scanning electron microscopy.
The results of this work suggest that An. aquasalis has high intraspecific
