This review describes efforts being undertaken to develop new tools and strategies to monitor and control dengue fever mosquitoes, mainlyAedes aegypti. With the growing realization that the magnitude of the global dengue/dengue haemorrhagic fever problem rivals that of malaria and infectious diseases such as hepatitis, and that old strategies are unsuitable in today's world, this problem requires urgent attention. The new tactics involve proper targeting of important breeding sites and diverse control methodologies ranging from biological control to molecular transformation of the vectors themselves.
