Mosquito Biology and Disease Transmission

The video tutorial covers the role of vectors, particularly mosquitoes, in transmitting diseases. It explains the life stages of mosquitoes and identifies three main types: Anopheles, Aedes, and Culex. The video details the differences in their eggs, larvae, and adult features, and discusses their feeding habits, highlighting that only female mosquitoes suck blood. It also identifies diseases caused by these mosquitoes, such as dengue, chikungunya, malaria, filariasis, and Japanese encephalitis. The tutorial concludes with a follow-up activity for students to research the full form of MDA.
