A comparative study on the abundance and the diversity of soil arthropods in organic and inorganic turmeric fields of Jagityal, erstwhile Karimnagar district, Telangana

Abstract

The present study has been undertaken in the Turmeric crop fields located at Shankarpally, a village in Jagityal district of Telangana. A total of 1132 insects from 13 orders were recorded during the study period of 2 years, from July, 2019 to February, 2020, from all the 32 sites. The present study was concentrated only on 13 orders. The abundant insect orders were Hemiptera, Collembola, Aranea, Thysanura, Coleopteran, Orthoptera, Carabidae, Dermaptera, Millipede and Isoptera. The Simpson index D value was calculated as 0.133, 1-D dominance value is 0.867, reciprocal index is 7.536; Shannon index H is 2.34 and evenness value is 0.91 for organic turmeric crop field. The present investigation revealed the relative abundance of the insect orders from the inorganic turmeric crop field is little varied with the taxonomic identity.
