Observations on mosquito breeding in rice fields in two ecological terrains of district Jabalpur, Madhya Pradesh

Studies on ecological succession of anophelines and the malaria vectors were carried out in rice fields located in two ecologically different terrains, i.e. plains and forested hills in Jabalpur district during monsoon (July-October 1995). Nine and fifteen species of anophelines were found breeding in the rice fields of plain and forested hill villages respectively. Anopheles culicifacies and An. subpictus were dominant species in both the areas. The percentage emergence of adults of An. annularis, An. nigerrimus and An. pallidus was higher in plain villages while the percentage of An. theobaldi, An. fluviatilis and An. jeyporiensis was higher in forested hill villages. Among malaria vectors, three species were found breeding in rice fields of hilly terrain, i.e. An. culicifacies, An. fluviatilis and An. stephensi whereas in rice fields of plains An. culicifacies and An. fluviatilis were recorded.
