Over 40% of the world's population is under danger from mosquito transmitted diseases, which are a growing global health challenge. Since 2000, malaria control has made significant progress, but of late it has slowed down. Aedes-borne arbovirus risk is also rising quickly due to the remarkable expansion of the dengue and chikungunya viruses, yellow fever outbreaks, and the Zika virus pandemic. To counteract this issues people used many vector control measures. Synthetic pesticides play a significant role in mosquito larval and adult control strategies, although their deployment is hampered by the development of resistance. As an alternative, various biological measures are being used including bacterial bio pesticides. They are extremely effective at controlling larvae due to their lack of resistance development and environmental friendliness. In this present review various biological control measures used for mosquito control are discussed.
