Biodiversity and Distribution pattern of Hemipteran insect bugs associated with Rice field Ecosystem of Sivaganga, TamilNadu, India

Resumen

In the present investigation, an attempt has been made to assess the relative abundance of Hemipteran insects associated with the Rice Field Ecosystems in the selected study area of Sivaganga District, Tamil Nadu, India with an aim to identify the composition of Hemipteran insect fauna at species level and determine the diversity/ distribution pattern of Hemipteran insects. A total of 21 taxa belonging to Hemipteran (true bugs) insects were collected from the study area. The mean
abundance (number/m 2 ) per month was ranged between 0 – 25. Shannon’s index value was 2.888, 2.853, 2.722, 2.853, 2.795, 2.767 for Jul, Aug, Sep, Oct, Nov, Dec respectively, while the Simpson’s index 0.9362, 0.9333, 0.9167, 0.9315, 0.9272,
0.9274 for Jul, Aug, Sep, Oct, Nov, Dec respectively. There was no significant difference in the relative abundance of insects between taxa from the sampling sites.
