Reducing Dengue Fever Through Biological Control of Disease Carrier Aedes Mosquitoes (Diptera: Culicidae)

Dengue is an infection that is carried by Aedes mosquitoes (Diptera: Culicidae) and can cause severe disease in peoples living in tropics. It is capable to cause headaches, pain and rash, and in other harsh types, may cause internal bleeding and then mortality of the patient. Currently, there is no vaccine for the treatment of dengue sickness and the most widely used methods for control of disease carrier Aedes mosquitoes are certain insecticides. These insecticides sometimes can harm the environment as well as peoples. For this reason, scientists are looking for better ways to prevent the spread of dengue disease by control of Aedes vector mosquitoes. Biological control of disease carrier Aedes mosquitoes is a suitable approach in Integrated Vector Management (IVM) program. Therefore, taking this objective into consideration, a broad biological control schedule is formulated based on the calendar of disease and vector’s profile. The natural enemies of Aedes mosquitoes take part in a vital task to limit their densities in an area. Such natural enemies consist of predators, parasitoids and pathogens. Biological control of dengue carrier mosquitoes can be augmented by means of maintenance of existing natural enemies, establishing new natural enemies and setting up a permanent population, and mass culturing and intervallic release of natural enemies, whichever may be on a seasonal basis or else inundatively. Thus, when non-toxic biological control method is found to control a key vector, the reduced use of pesticides and increased survival of natural enemies frequently reduce the transmission of important mosquito’s borne diseases in the community.
