Probable trajectories associated with the transport of Ochlerotatus albifasciatus during a strong wind event in Buenos Aires city (Argentina)

Because of its capacity to infect human beings and domestic animals with a number of different viruses, the study of the mosquito Ochlerotatus albifasciatus (Macquart, 1938, (Diptera: Culicidae)) assumes great importance from the point of view of sanitation. It is a well-known fact that the abundanc...
