## Anopheles stephensi Breeding Habitat **Key Point:** Anopheles stephensi, the primary urban malaria vector in India, breeds in clean, stagnant water in artificial habitats such as wells, tanks, cisterns, and domestic water storage containers. This is the defining ecological feature that makes it an urban vector. ### Indian Malaria Vectors and Their Habitats | Vector | Primary Habitat | Breeding Water | Geographic Distribution | |--------|---|---|---| | An. stephensi | Urban/peri-urban | Clean stagnant water (wells, tanks, cisterns) | Cities, towns (Delhi, Mumbai, Bangalore) | | An. culicifacies | Rural/foothill | Clean flowing streams, springs | Foothills, rural areas | | An. fluviatilis | Rural/foothill | Clean flowing streams | Foothill zones | | An. minimus | Forested/foothill | Clean flowing streams | Forested areas, foothills | | An. sundaicus | Coastal | Brackish water, lagoons | Coastal regions | **High-Yield:** An. stephensi is anthropophilic (human-seeking), endophilic (indoor-resting), and breeds in urban water storage — making it the most significant vector for urban malaria in India. Its adaptation to artificial water bodies is crucial for epidemiological control strategies. **Clinical Pearl:** The presence of An. stephensi in urban areas like Delhi, Mumbai, and Bangalore has shifted malaria epidemiology from a predominantly rural disease to an urban public health threat. This vector's ability to breed in small quantities of clean water in household containers makes it difficult to control. **Mnemonic:** **STEP-CLEAN** — Stephensi breeds in STEP-wells and CLEAN stagnant water (artificial habitats), unlike other Anopheles species that prefer flowing water.
