Diversity and abundance of insect fauna in groundnut at IIOR-Narkhoda farm of Southern Telangana Zone, Telangana, India

AbstractPresent research is aimed to determine key diversity indices, including the Shannon-Weiner diversity index, Margalef species richness index, Pielou’s evenness index, Simpson diversity index, and the relative abundance of species, genera, and families from various insect orders. A total of 6,306 insects belonging to 13 orders, 57 families, 78 genera, and 91 species were recorded using different trapping methods. Hemiptera emerged as the most dominant order, comprising 28.75% of the total insect population and representing 18 species, while Thysanoptera accounted for 20.52%. Diptera exhibited the highest Shannon-Weiner diversity index (H = 2.108), species richness (R = 1.615), and Simpson diversity index (1-D = 0.853). Odonata demonstrated the highest evenness (e = 0.991).
