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.
在季风来临前、季风期和季风过后的季节，对迪布鲁-赛库瓦生物圈保护区的核心区和缓冲区连续三年进行了昆虫学调查。共检测到11个属的52种蚊子。按蚊属（18种）占主导地位，其次是库蚊属、伊蚊属、曼蚊属、阿蚊属、小毛蚊属、脉毛蚊属、马来蚊属、巨蚊属、费蚊属和伪费蚊属。与核心区（10个属的42种）相比，森林保护区有人类居住的缓冲区出现的物种数量最多（10个属的49种）。在缓冲区，季风季节记录到的物种数量最多（38种），其次是季风过后（35种）和季风来临前（34种）。而在核心区，季风过后季节采集到的物种数量最多，其次是季风来临前季节和季风期。在核心区和缓冲区，分别从地面水池栖息地和缓流溪流中记录到最多的物种。在病媒中，印度认定的潜在日本脑炎病媒非常普遍。本研究首次提供了迪布鲁-赛库瓦生物圈保护区记录的现有蚊子物种清单。
