Entomologist categories around 3500 species of mosquitoespresent in the world. Some species of mosquitoes act as vectors, carriers and
pathogen that cause diseases like, Malaria, Dengue, Chikungunya, Filariasis and
Encephalitis.
The male mosquitoes feed on plant and fruit saps. But the
female mosquitoes feed on human and animal blood, which has the protein
required by them to lay their eggs.
Anopheles stephesi and Anopheles culicifacies causes
Malaria. These types of mosquitoes breed in clear water and tanks. They are
night biting mosquitoes. They transmit virus from the saliva to humans and
animals. Human and animal blood has the ability to clot. To stop clotting and
enable them to draw blood, mosquitoes first inject saliva which has enzymes
that retard clotting of blood when pierced. Thus the virus gets transmitted
through the saliva of mosquitoes.
Aedes aegypti and Aedes albopictus are the two species that
causes Dengue, Chikungunya. They are known as Asian Tiger Mosquitoes, for
having white lines on them. They are usually found in forest and breed in
artificial containers with stagnant water like pots, cups, mugs, coconut shells
and plastic bags. They are day biting mosquitoes and more active in morning and
evenings. So coils and nets may not be useful. The name Dengue means break bone
fever and cramping pain.
