Anopheles stephensi is the principle vector of malaria. The present study is based on the ovipositional site preferences of An. stephensi with respect to different pH, colour, and water types. For the study, we used different pH range such as 3, 5, 7, 9, and 11, different coloured bottom petridishes like, red, green, blue, yellow, white, and black were used. Different water samples were collected from various sites of Kota. We used different water like rainwater, fresh standing water, standing water with algae, sandy water, sewage water, distilled water, and tap water. The present study was carried out under laboratory conditions. Our findings showed that An. stephensi deposited more number of eggs in pH 7 (Tap water) suggesting that female mosquito prefer this pH range for oviposition whereas more number of eggs were observed in black bottom petridishes suggesting that black colour is comparatively more attractive than other colours. In the case of different water types, fresh standing water with algae showed a greater number of eggs laid than other water types.
