Abstract:
Orthoptera collected from rice fields of Coimbatore and Bhavanisagar, India comprised Acrididae (4 species), Pyrgomorphidae (1 species), Tetrigidae (2 species), Tridactylidae (1 species), Tettigoniidae (4 species), and Gryllidae (3 species). The assemblage included herbivore (9 species), carnivores (3 species) and omnivores (3 species). Conocephalus rentzi Farooki and Usmani, 2018 (Tettigoniidae) is recorded for the first time in Tamil Nadu. The dominant fauna included Oxya hyla, O. fuscovittata (Acrididae) and Metioche vittaticollis (Gryllidae). Abundance of Hieroglyphus banian (Acrididae) and Eucriotettix tricarinatus (Tetrigidae) were observed to be minimal. Among the two places of study, the species richness, diversity and evenness of Coimbatore (α 2.34, 2.62, and J ̍ 0.44) was higher than that of Bhavanisagar (α 2.03, 1.66, and J ̍ 0.37). Jaccard index shows 67% of similarity between Coimbatore and Bhavanisagar.
