Culextritaeniorhynchus breeds extensively in paddy fields in villages located in Sonipat district, Haryana close to Nerela border, North Delhi from where field studies carried out at NICD led to the discovery of a tiny microbe Chilodonellauncinata (protozoan parasite) that kills JE vector larvae growing in paddy fields and burrow pits. In contrast, in the absence of paddy fields in East and South Delhi vast marshes and disused ground pools with profuse growth of water hyacinth were the most preferred breeding habitats for Cx. tritaeniorhynchus mosquitoes. Larvae of this species in Delhi were found to be tolerant to Ch. uncinata infection. Though Delhi and adjoining villages of Haryana are not endemic to JE, sporadic cases were reported from many areas of Delhi during 2002–2005 and recently during 2011. Aim of this chapter was to use the BPD hop cage method in the ecological study of Cx. tritaeniorhynchus, principal vector of JE in India in and adjoining areas of Delhi, non endemic area in Northern India. Differential role of Chilodonellauncinata was demonstrated on the population abundance of Cx. tritaeniorhynchus in diverse ecological situation in and around Delhi. Situation specific JE vector control/management strategies are suggested to prevent transmission of the disease.
