Mosquitoes are a serious threat to public health transmitting several dangerous diseases for over 2 billion people in the tropics[1]. Aedes aegypti (Ae. aegypti), the primary carrier for viruses that cause dengue fever, dengue hemorrhagic fever and yellow fever is widespread over large areas of the tropics and subtropics. Mosquito control and personal protection from mosquito bites are currently the most important measures to control these diseases. Many approaches have been developed and tried to tackle mosquito menace. The use of larvicides and repellents is an obvious practicality and economical means of preventing the transmission of these diseases to humans.
