Abstract
Bathi lake in Davangere was studied for insect composition and Physico-chemical as well as trace metal parameters at five sites, for a period of six months from April to September 2019. A total of 11 species of aquatic insects belonging to 04 orders and 07 families were recorded. Among orders, Hemiptera consists of 08 species followed by Trochoptera, Ephemeroptera and Araneae with 01 species each respectively. Human activities, agricultural runoff and discharging of waste water creates threat to the biota of the lake by altering the water quality. Different parameters studied were pH, electrical conductivity, nitrogen, phosphorus, zinc, copper, iron and manganese levels. The results obtained from the current study indicated that the water pH of Bathi Lake was alkaline in nature, EC, nitrogen and phosphorus contents were in moderate concentrations. Manganese and iron levels of sediment sample in Bathi lake shows maximum level of pollution and ecological balance is disturbed. One-way ANOVA and Tukey HSD test were calculated to know the significant difference between the samples.
