Seasonal dynamics and abundance of mosquitoes in Sivasagar district of upper Assam, India with special reference to environmental factors

Author(s): Daisy Konwar, Rimen Bordoloi and Niranjan Nath
Abstract: The study was conducted on diversity as well as dynamic of mosquito fauna of the Sivasagar district, Assam, India for a period of one year. Total 26288 female mosquitoes belonging to 36 species under 6 genera were collected. T-test, Correlation and Regression were used to evaluate the collected data at significance level below .05 and .01. The dominant species was Cx.quinquefasciatus Say (13.77%) followed by Cx.tritaeniorhynchus Giles (11.27%), Ar.subalbatus coquillett (8.9%) and Cx. vishnui Theobald (8.25). PMHD of Anopheles (56.24), Culex (104.84), Mansonia (9.7) and Armigeres (14.55) were higher in the monsoon while Aedes (4.83) were higher in Post monsoon and Toxorhynchites (0.12) were higher in Premonsoon. Mosquito abundance were significantly positively correlated with temperature (r=0.88; p< .01), rainfall (r=0.91; p<.01) and humidity (r=0.83; p<.01). The Regression analysis showed strong linear relationship between mosquito abundance and environmental factors (R2= 0.788, 0.915, 0.832 for temperature, rainfall and humidity respectively).
