Urban malaria and its vectors Anopheles stephensi and Anopheles culicifacies (Diptera : Culicidae) in Gurgaon, India.

The seasonal variation in the density of immature and adult malaria vectors Anopheles stephensi and An. culicifacies were recorded from January to December, 1986 in urban Gurgaon, India. The highest combined anopheline larval density (2.3 per dip) was recorded in the 31st week. The peak adult density for malaria vectors An. stephensi (4.14 per man hour) and An. culicifacies (1.02 per man hour) were reported in the month of August. The highest percentage of total infestation for anophelines and other breeding habitats were in tanks (48.72%) and ponds (6.41%) in Autumn and wells (4.79%) in the Winter season. The highest population of An. stephensi and An. culicifacies were collected from the peripheral area in comparison to central part of the study area. Maximum malaria cases along with highest larval density (1.8 per dip) were recorded from Sector 3.
