Summary Malaria has declined around Chilika Lake (85°20′ E, 19°40′ N) in Orissa State, India, from hyperendemicity in the 1930s to hypoendemicity during recent decades. Six decades ago, 21 spp. of Anopheles mosquitoes (Diptera: Culicidae) were recorded from this area, including the well known Indian malaria vectors An. culicifacies Giles , An. fluviatilis James , An. maculatus Theobald , An. stephensi Liston and An. sundaicus (Rodenwaldt), the last formerly regarded as the main vector locally. Surveys of Chilika area during 1995–96 found 8 spp. of culicine plus 14 spp. of anopheline mosquitoes, the latter comprising An. subpictus Grassi sensu lato , An. hyrcanus (Pallas) s.l., An. vagus Dönitz, An. annularis van der Wulp s.l ., An. culicifacies Giles s.l. , An. aconitus Dönitz , An. varuna Iyengar, An. barbirostris van der Wulp s.l. , An. philippinensis Ludlow, An. ramsayi Covell, An. jeyporiensis James, An. pallidus Theobald, An. tessellatus Theobald and An. karwari James in decreasing order of abundance. Among indoor‐resting female mosquitoes, the anthropophilic index was 4–7% and some species ( An. culicifacies, An. subpictus, An. vagus ) tended to enter houses for resting after blood‐feeding outside. Females of potentially infective age (three‐parous) were obtained for An. culicifacies (11%) and An. annularis (< 2%), the more abundant established vector in this coastal area, but not for small samples of An. subpictus and An. vagus . Anophelines reported previously but not found in our survey were An. fluviatilis, An. jamesii Theobald , A. maculatus, An. splendidus Koidzumi , An. stephensi , An. theobaldi Giles and the former main vector An. sundaicus.
