The Culex mosquito, or house mosquito, is a significant vector of West Nile virus, Japanese encephalitis, St. Louis encephalitis, filariasis, and avian malaria--diseases that affect humans, birds, and other animals. Known for feeding on human blood, a Culex mosquito was observed sitting on a mirror, with multiple reflections visible, inside a house in Tehatta, West Bengal, India, on September 20, 2025.

Mosquito larvae, commonly known as ''wrigglers,'' are aquatic and characterized by a large head, a broad thorax, and a narrow, wormlike abdomen. They typically hang just below the water's surface, breathing air through tubes located at the end of their abdomen. The nutrients acquired during the larval stage are crucial for the mosquito's development into an adult. Larvae possess a specialized organ called a siphon, which they use to breathe air at the water's surface. They feed on organic matter found in standing water, such as that in unused fountains, buckets, paint cans, and rain barrels. Mosquitoes are vectors for numerous diseases, including dengue, malaria, chikungunya, Zika, West Nile virus, La Crosse virus, Japanese encephalitis virus, and yellow fever. According to the World Health Organization (WHO), vector-borne diseases account for more than 17% of all infectious diseases, causing over 700,000 deaths annually. Mosquito larvae sampling is currently underway in Tehatta, West Bengal, India, as of 15/09/2024.

Armigeres mosquito (Armigeres sp.) is a genus of mosquitoes belonging to the Culicidae family. Some species of Armigeres can raise their hind legs to create an egg. Adults of Armigeres are morphologically similar to species of other Aedine generic-level taxa in the Oriental and Australasian regions, but they are generally larger and usually have the proboscis slightly curved downwards and flattened laterally. Armigeres species are associated with lowland and dipterocarp forests but are never found in primary forests. Many species of Armigeres attack humans. For example, Armigeres subalbatus is a species complex of zoophilic mosquitoes found in Sri Lanka, India, and Bangladesh. It can carry parasites and viruses that cause diseases in humans, including malaria, Japanese encephalitis, and filariasis. It is also a potential vector for the Zika virus. Armigeres subalbatus is part of the Culicinae subfamily and is similar in morphology and genetic phylogeny to Aedes mosquitoes. It feeds on blood from both humans and animals and thrives in areas near human habitation. Armigeres subalbatus was originally associated with forests but now thrives in rural and suburban areas. An Armigeres mosquito is resting under a leaf in a forest in Tehatta, West Bengal, India, on 04/04/2024.

Diseases transmitted by mosquitoes and other insect vectors continue to place a critical burden on the world's poor, particularly in tropical and subtropical areas including countries in the South-East Asia Region. Some pockets in Nadia, North 24 Parganas and Hooghly have seen a sudden rise in cases, and at least five people in Kolkata have died due to dengue in the last week. According to World Health Organization (WHO), Vector-borne diseases account for more than 17% of all infectious diseases, causing more than 700 000 deaths annually. They can be caused by parasites, bacteria or viruses. Malaria parasitic infection transmitted by Anopheline mosquitoes causes an estimated 219 million cases globally, and results in more than 400,000 deaths every year. Most of the deaths occur in children under the age of 5 years. Dengue viral infection is transmitted by Aedes mosquitoes. More than 3.9 billion people in over 129 countries are at risk of contracting dengue, with an estimated 96 million symptomatic cases and an estimated 40,000 deaths every year. Other viral diseases transmitted by vectors include chikungunya fever, Zika virus fever, yellow fever, West Nile fever, Japanese encephalitis. Mosquito larval or larvae sampling is underway by a voluntary organization at Tehatta, West Bengal; India on 31/07/2023.
