Abstract
The study of the aquatic insects was carried out in the ‘Na pukhu’ pond of Bhaktapur
Municipality during March 2014 to August 2014 in pre monsoon and monsoon. A total of
4181 insects belonging to five genera under five families and three orders were identified
including individuals of one unidentified species. During the study period the most
abundant order was Diptera in pre monsoon and Hemiptera in monsoon. The diversity
index, species richness and evenness of the insects were recorded higher in the monsoon
in comparison to pre monsoon. The relation of diversity with physical parameters was
correlated by using Karl Pearson’s Correlation Coefficient which shows positive relation
with temperature, pH and alkalinity but negative with DO in pre monsoon. In monsoon,
diversity shows positive correlation with alkalinity but negative with temperature, pH and
DO. The analysis showed Chironomus sp. as most abundant during the study period.
