Mosquito Larvae Sampling

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. (Photo by Soumyabrata Roy/NurPhoto via Getty Images)
