A study was conducted from 2020-2021 to identify the tephritid species in fields of Pumpkin, Bottle gourd, Mango, Guava, Ber and Citrus. Through Methyl Eugenol traps, two species namely Bactrocera dorsalis (Hendel) and Bactrocera zonata (Saunders) were collected. Through cue-lure traps, six species namely Zeugodacus tau (Walker), Zeugodacus cucurbitae (Coq.), Bactrocera rubigina (Wang and Zhao), Zeugodacus caudatus (Fabricus), Bactrocera divenderi Maneesh, Hancock and Prabhakar and Dacus longicornis (Wiedemann) were collected. Four species namely Zeugodacus tau (Walker), Zeugodacus cucurbitae (Coq.), Bactrocera dorsalis (Hendel) and Bactrocera minax (Enderlein) were recovered from infested fruits of pumpkin, bottle gourd, cucumber, ber and citrus. According to the Shannor-Weiner Diversity Index, species diversity was maximum in pumpkin among different fields and maximum in ber from infested fruits. Understanding the species diversity and determination in a crop ecosystem aid in strategising the management options. Clumped distribution was observed in several fields.
