The present study was conducted on the incidence of parasitoids of Melanagromyza obtusa (Malloch) at Research Farm and Laboratory, Agricultural Entomology Unit, Agriculture Research Station, Badnapur (Vasantrao Naik Marthwada Krishi Vidyapeeth [VNMKV], Parbhani), Maharashtra, India during Kharif season of 2014-15. Six hymenopteran parasitoids recorded were; Eduderus sp. Ashmead, Systasis dasyneurae Mani, Torymus sp. Dalman, Epitranus sp. Walker, Eurytoma sp. Illiger and Ormyrus sp. Walker. As per the literature available and reviewed; Systasis dasyneurae Mani, Torymus sp. Dalman and Epitranus sp. Walker are the first ever record for new host association reported from M. obtusa maggots and pupae as ecto and endo-parasitoids. The incidence of natural parasitism of Systasis dasyneurae Mani, Torymus sp. Dalman and Epitranus sp. Walker ranged from 1.69 to 7.32, 5.08 to 29.27 and 2.13 to 4.88 per cent, with a mean parasitism of 0.98, 9.70 and 0.64 per cent, respectively. The new record of natural parasitism of M. obtusa larvae and pupae by Torymus sp., Systasis dasyneurae and Epitranus sp. would add knowledge on biological control of the pest.
