In the present investigation is an attempt to assess the relative abundance of insects in different microhabitats of study site in Sirumalai hill i To identify the composition of insects fauna at genus level ii To study the stream habitat types and iii To determine the diversity and distribution of insects in different microhabitats The total of taxa belonging to hemiptera true bugs coleopteran beetles and odonata dragonflies were collected in all the three sites Hemipteran group contributed to the total community while the values coleoptera and odonata were and The mean abundance number m per month was ranged between and for hemiptera coleoptera and odonata respectively The Shannon rsquo s index values were and for sandy pool rocks and riffles while the Simpson rsquo s index was and There were no significant difference in the relative abundance of insects between taxa and microinvertebrate of the stream indication that the evenness of taxa at the sampling sites The understanding of stream ecology a comprehensive approach integrating biotic and a biotic components of stream is essential hence a preliminary report on biodiversity of aquatic insect community in Sirumalai hill stream was investigated |
