Impact of Environmental Changes on Mosquitoes and Disease Transmission

Abstract

Mosquitoes are excellent indicators of environmental changes caused by man, especially as environmental degradation promotes the proliferation of mosquito species with adaptive plasticity which can develop in suburban areas and can carry and transmit pathogens to humans and animals. Therefore, environmental changes are evaluated as risk factors of emerging mosquito borne diseases. The current knowledge of diversity and relative abundance of mosquito vectors as a function of habitat change, survival rate of several mosquito species, as well as their biting rates leading to the rapid spread and emergence of new diseases is not comprehensive. Noteworthy, the interaction between vector-host-parasite in natural environment can be disrupted when deforestation occurs. This review provides useful knowledge for vector control, while allowing the monitoring of biological indicators of environmental changes caused by man, an important step in understanding the dynamics of mosquito vector distribution under changing environment.
