Diversity of Mosquito (Diptera: Culicidae) Inthe Sipadol V.D.C. of The Bhaktapur District

Abstract

The collections of Mosquitoes were done from May2007 to September 2007 inSipadol V.D.C. of Bhaktapur district. The collection of mosquitoes was done by randomsampling. The collection include four genera of mosquitoes viz:Culex, Anopheles,Aedes, andArmigeres.These collected genera were statistically significant. The population of Culex wasfound high in the study area. The maximum collections were done from the dwelling in thevicinity of paddy field, surrounding with stagnant pond and ditches. The density ofAnophelesandAedesare lowest in comparison to Culex andArmigeres.The mosquito collection wasdone from 5to 7am in the morning and in the evening from 6 to 8pm with the help of selfbaited mosquito net and suking with hand-aspirator. Altogether 434 specimens of mosquitoeswere collected from twenty sampled houses. The mosquito diversity in the study areaincludes the four different types of genera which were most prevalent in the month of June,July and August and least in the month of May and September. The mean density of mosquitowas positively correlated with Temperature (r = 0.76022) Rainfall (r = 0.886) and Relativehumidity(r = 0.896264).The study found out that the most diverse fauna in the study areaduring the study periodwas the genus Culex (H' = 0.157), similarly, Armigeres(H' = 0.154),Anopheles(H' = 0.1505) and the least diverse fauna was found to be the genusAedes(H' = 0.048). About 44% ofCulex, 28% ofArmigeres, 25% ofAnophelesand 3% ofAedeswere collected from the study area during the study period.
