Fatal yellow fever mosquitoes

Lately, people have started to know about the diseases that spread from the fatal yellow fever mosquitoes. It has, therefore, become essential to know how to prevent these diseases from spreading. Recently, a study was conducted by researchers at Yale School of the Environment. In the research, they mentioned the new way in which these mosquitoes move through the environment and surroundings. The study will play a very important role in controlling the insect from spreading the diseases it brings in people.

As every year passes by, the number of deaths of people has been increasing due to malignant diseases like the Zika virus, dengue fever, and chikungunya, which are vectored by the yellow fever mosquitoes. Discovering and looking for various other methods, in addition to the ones already existing, to control these insects is a basic yet the most important step in the battle against illnesses as these mosquitoes often bite humans and spread diseases for which the vaccines are not still available.
The research conducted at the Yale School developed the latest method to follow the movement of the yellow fever mosquitoes within the environment. After having combined the genetic data from mosquitoes and the environmental data from satellites, the authors came up with “landscape connectivity”, which shows how a landscape allows movement of different organisms and their genes within largely-spread areas.

Evlyn Pless, who is a postdoctoral researcher at the University of California, Davis, and a Ph.D. graduate of Yale’s Department of Ecology and Evolutionary Biology, said, "Connectivity maps allow managers to make informed decisions based on how mosquitoes are likely to move through a landscape." He further added, "Our results suggest that in the southern U.S., Ae. aegypti travels by a mix of natural and human-aided dispersal, taking advantage of regions that are warmer and flatter, as well as human transportation networks."
