Abstract

The species diversity, breeding habitats and biting activities of the mosquito vectors of Japanese B Encephalitis were investigated in Malawak, Bustos, Bulacan from July 2005 to April 2006. A total of 2,336 mosquito larvae were collected from various aquatic habitats, namely: idle land, trapped water, fishpond, rice paddy and irrigation canal. The predominant species collected were Culex tritaeniorhynchus, Cx.gelidus and Cx.bitaeniorhynchus, Larvae of Cx.tritaeniorhynchus were abundant in idle land and fishpond. Cx.gelidus were mostly collected from trapped water. Cx. bitaeniorhynchus were consistently collected from rice paddy, trapped water and idle land. Relatively few mosquitoes were collected from irrigation canal. Three species occurred most frequently in a habitat with 10-30 cm deep stagnant, murky water containing abundant emergent and/or floating vegetation under full sun exposure. Results showed that the predominant mosquito biters collected in Carabao-baited trap were Cx. quinquefasciatus (30%), Cx. tritaeniorhynchus (29%) and Cx. gelidus (14%). On the other hand, Cx. tritaeniorhynchus (52%) and Cx. quinquefasciatus (36%) were the most abundant biters collected in the pig-baited trap
