Aquatic Insect Fauna and Diversity in Urban Fresh Water Lakes of Tripura, Northeast India

Freshwater lakes are integral part of urban ecosystem and provide numerous benefits to human beings directly or indirectly. An inventory was carried out to study the aquatic entomofauna, their diversity and distribution in three urban freshwater lakes of Tripura, northeast India during January to May, 2012. A total of 2159 individuals representing 31 species belonging to 23 genera, 15 families and 4 orders were recorded. Maximum of 30 species and 1191 individuals of aquatic insects were recorded in vegetation rich Maharaja Bir Bikram College Lake and minimum of 11 species and 215individuals were recorded in vegetation poor Laxminarayan Bari Lake. Insects belonging to the orders Hemiptera (32.26%) and Odonata (32.25%) showed higher species richness followed by those belonging to Coleoptera (25.81%) and Diptera (9.68%), respectively. Maximum diversity (H = 3.03) and least dominance (D = 0.06) and minimum diversity (H = 1.50) and maximum s s s dominance (D = 0.06) of aquatic insects was recorded in Maharaja Bir Bikram College Lake and Laxminarayan s Bari Lake, respectively. Richness estimators Chao 1 and Chao 2 provided the best predicted value of species richness. Three species are reported here for the first time from the state. Dominance of hemipteran and coleopteran insects suggested that urban lakes of Tripura are relatively less polluted.

Distribution and diversity of aquatic insects of Vellayani lake in Kerala

The diversity of insect fauna of Vellayani lake in Kerala was represented by 60 species classified under 37 families and 8 orders. Among the entomofauna collected from the lake, the order Coleoptera was diverse in number of genera (22). Shannon index was highest in station 2 (3.214) and lowest (2.839) in station 4. The higher richness index was also recorded in station 2 (6.331), though the lowest species richness was observed in Station 1 (5.205). The order Ephemeroptera is represented in Vellayani lake by the families Baetidae and Caenidae, which are considered as an indicator of water quality. Of the 15 metrices selected, taxa richness, Composition measures, Tolerance and Intolerance and Functional groups were also found out for all the stations. In the present study, the percentage of Ephemeroptera, Plecoptera, Trichoptera (EPT) taxa richness and diversity remained high in Station 1, 2 and 3 but reduced drastically in stations 4 and 5. The high HBI value recorded at station 4 is due to the abundance of pollution tolerant taxa such as Chironomidae, Tabanidae, Culicidae and Anophilinae. The results of the study reveal greater diversity of aquatic entomofauna in Vellayani freshwater lake and suggest the possibility of using insects effectively for biomonitoring programmes.

Diversity and Community Structure of Aquatic Insects in a Fresh Water Lentic System of Purba Medinipur District, W.B., India

Indian Journal of Biology, 2016

29 species of aquatic insects have been recorded from a weed infested man made wetland near Tamluk Station. Hemiptera was numerically the most abundant group comprising 39% of the total aquatic insects followed by Coleoptera (36%) and Odonata 25%. Hemiptera and Odonata were represented by 10 species each while Coleopteran was represented by 9 species. Of these only one coleopteran species, Canthydrus latitabilis was found to be dominant. The water body under investigation was considered moderately polluted. On the basis of Diversity index, Evenness value and Dominance value indicated the equitability and heterogeneity of the aquatic system. While Coleoptera and Odonata exhibited a peak in July and May respectively but no distinct peak could be seen for Hemiptera. Correlation between the abiotic factors and insect species revealed that abiotic factors had some regulatory effects on aquatic insect population.

Use of Aquatic Insects to Assess the Biological Status of a Perennial Pond in Assam, Northeast India

Indian Journal of Entomology

An investigation was carried out on “Hazara Pukhuri”, a perennial pond in Sonitpur district, North East India, between July 2019 and June 2020. To assess the health of the waterbody, various biotic and diversity indices were applied, with aquatic and semi-aquatic hemipteran populations functioning as bioindicators. The pond’s hemipterans include 17 species from 13 genera and 8 families, including Gerridae, Corixidae, Pleidae, Notonectidae, Nepidae, Belostomatidae, Hydrometridae, and Mesoveliidae. The biotic indices Average Score per Taxon (ASPT), Stream Invertebrate Grade Number-Average Level (SIGNAL-2), and The Biological Monitoring Working Party (BMWP) Score, as well as other diversity indices, were assessed to indicate that the waterbody was unpolluted/ slightly polluted. The presence or lack of littoral vegetation and flooding and drying of nearby shallow water pools and swampy areas were important drivers of the distribution, abundance, and community composition of aquatic and ...

A comparative study of the aquatic insect diversity of two ponds locatedin Cachar District, Assam, India

TURKISH JOURNAL OF ZOOLOGY

Ponds play a vital role in the conservation of aquatic biodiversity at the local level apart from other lakes and rivers. A comparative study was carried out on the aquatic insect diversity of two different ponds, one in an urban area (urban pond, UP) and another in a rural area (Jalinga pond, JP). Two seasonal collections (postmonsoon and winter) were made to check the pollution status of the two ponds based on the aquatic insect community and physicochemical properties of water. Consequently, 29 species, 17 families, and 5 orders of aquatic insects from UP and 17 species, 8 families, and 3 orders from JP were recorded. Aphelonecta sp., Cloeon sp., and Micronecta sp. were the eudominant species recorded. According to the Shannon (H') index, UP was more diverse than JP. Family level biotic indices and scores further proved the better water quality of UP than of JP. Hence, it can be said that urban ponds have an important role to play in biodiversity conservation.
