Study revealed presence of aquatic insect order Hemiptera, two families (Gerridae and Notonectidae) and three species (Anisops sp. , Gerris sp. and Buenoa sp.) from the ponds located around Cement factory, Badarpur. Anisops sp. was found eudominant in all the ponds except pond 1 where Gerris sp. was eudominant. Ponds (pond 5 and 6) located around Bokajan Cement Factory revealed presence of two aquatic insect orders (Hemiptera and Odonata), five families (Notonectidae, Gerridae, Nepidae, Coenagrionidae and Libellulidae) and eight species (Gerris sp., Anisops sp., Limnometra sp., Ranatra sp., Pseudogrion sp., Ischnura sp., Libellula sp.,Sympetrum sp.). In Pond 5, Gerris sp. was found eudominant . In Pond 6, Anisops sp. was found eudominant. In each of the five ponds diversity index (Shannon H' Log Base 10)values we...
