The mosquito genome: organization, evolution and manipulation.
Apart from the genetic flexibility of the vectors, impediments to the control of vector-borne diseases include the rapid spread of drug resistance throughout parasite populations, the increasing movement of people to and from disease-endemic regions and the limited funds and public health infrastructures of most developing countries. The widely used residual insecticides and antiparasitic drugs have been inadequate solutions to the problem of vector-borne disease control. New approaches are needed. The enormous impact of recent developments in molecular genetics on the understanding of basic biology and human disease has stimulated a re-examination of the prospects for genetic manipulation of vector populations as a means for reducing or eliminating vector-borne diseases, especially malarial. Although control scenarios that exploit this technology may never be realized, Nora Besansky and Frank Collins emphasize that the increase in knowledge of basic mosquito biology on which these ideas depend will inevitably stimulate novel approaches to the control of mosquito-borne diseases.
