abstract
Incidence of fruit flies in different cucurbitaceous crops were studied during the present research work. Nine species of Dacine fruit flies viz., Bactrocera (Bactrocera) dorsalis (Hendel), Bactrocera (Bactrocera) latifrons (Hendel), B. (Hemigymnodacus) diversa (Coquillett), B. (Sinodacus) hochii (Zia), B. (Zeugodacus) caudata (Fabricius), B. (Zeugodacus) cucurbitae (Coquillett), B. (Zeugodacus) tau (Walker), B. (Parasinodacus) cilifera (Hendel), and Dacus (Callantra) longicornis (Wiedemann) associated with cucurbit crops have been recorded for the first time from Tripura, a North Eastern state of India. B. (Sinodacus) hochii and B. (Parasinodacus) cilifera are the new country records for India. Brief description of the species recorded and taxonomic keys for identification of these fruit flies are provided.
