Keywords: Abstract:
Diversity of The present investigation deals with the studies on water quality
Aquatic insects parameters and Diversity of Aquatic insects from Bori reservoir,
from Bori Naldurg, Dist-Osmanabad, Maharashtra. The work was carried out
reservoir during the year 2021 (January to December) the abiotic parameters
were studied from month to month. The diversity of water insects
was studied. The species were found during the study period.

INTRODUCTION
The quality of water play a vital role in the growth of aquatic animals and their
population. The water quality standards below and above the optimum level may lead to stress
or death among the aquatic animals. The quality of water may be changed due to pollution of
water body. The quality of water depends on physical, chemical and microbiological factors.
Aquatic insects are important group of organisms in freshwater bodies and plays an imp
role in the processing and cycling of nut nets. According to Larrnberti Moore (1948), Aquatic
insects belongs to several feeding groups i.e. filter feeders, deposit collectors scrapers, shredders
and Predators. Aquatic insectors are are bioindicators of water pollution Wieder Holm, 1948 :
Metcaffe (1989). These insects form a link between the nutritional cycles of aquatic ecosystem.
The workers like Sinha and Sinha, Kaushik et al (1990), Pandey et al (1992), Singh (1993). Arvind
Kumar (1994), works on seasonal water quality of fresh water bodies.
Due to lack of information about the water and Aquatic insects interrelationship the work
was undertaken.

MATERIALS AND METHODS
The Aquatic insects were collected by insect collecting net made up of nylon cloth having
mesh size 40-80 cm . The samples were cleaned and preserved in 5 percent formalin. The
2
identification of insects was done with the help of standard literature of Tonapi (1959), Michael
(1973), Macan (1959).
Monthly collection of water samples was done by using plastic containers of 5 lit. size. The
samples were brought to laboratory for analysis. The metrological parameter i.e. air temp. and
humidity were determined in the field. The samples were analysed by using standard methods
of water analysis given by Trivedy and Goel (1984), and APHA, AWWA, WPCF (1985) and
Kondarkar M.S. 1995.
