Abstract
Entomological surveys were conducted for three consecutive years in core and buffer zone of the Dibru-Saikhowa biosphere
reserve in pre monsoon, monsoon and post-monsoon seasons. A total of 52 species of mosquitoes under eleven genera have been
detected. The genus Anopheles (18 species) was the predominant followed by Culex, Aedes, Mansonia, Armigeres, Mimomyia, Ochlerostatus,
Malaya, Toxorhynchites, Ficalbia and Aedeomyia. The buffer zone of the forest reserve where human habitations are there exhibited the
presence of maximum number of species (49 species under 10 genera) in comparison to core zone (42 species under 10 genera). In buffer
zone, maximum numbers of species (38) were recorded in monsoon season followed by post- monsoon (35 species) and Pre-monsoon
season (34 species). Whereas in core zone, maximum number of species were collected in post monsoon season followed by pre monsoon
season and monsoon season. In Core and buffer zone, the maximum species were recorded from the ground pool habitat and slow flowing
stream respectively. Among the disease vectors, the potential Japanese encephalitis vectors incriminated in India were very much
prevalent. This study provides the list of available mosquito species recorded for the first time in the Dibru-Saikhowa biosphere reserve.
