This latest volume of The Biology of Mosquitoes addresses fundamental aspects of the interactions between mosquitoes and the viruses and bacteria that infect them, bringing together the latest information and older important findings from the lab and the field, providing readers with the broadest coverage available anywhere on the subject. Following an introduction that reviews developments in the taxonomy and nomenclature of aedine mosquitoes, chapters describe host-parasite interactions and mosquito immune responses to their pathogens and bacteria, the characteristics of arboviruses and viruses infecting only mosquitoes, the transmission and epidemiology of the most important arboviruses, and the interactions between mosquitoes and three bacteria identified as potential means of controlling mosquito populations and disease spread.
