Mosquitoes are unquestionably the most medically important arthropod vectors of disease. The maintenance and transmission of the pathogens that cause malaria, lymphatic filariasis, and numerous viral infections are absolutely dependent on the availability of competent mosquito vectors. Although the medical community has known for over a century the role played by mosquitoes in the transmission of malaria and lymphatic filariasis, these diseases continue to have a devastating influence on less privileged populations throughout the tropical and subtropical regions of the world. The present study was done to identify the different culicine mosquitoes in four different districts in Sohag Governorate and to describe and compare the various types of sensilla located on their antenna and maxillary palps using scanning electron microscopy.
