Small cabbage white butterfly, Pieris rapae is the most important insect pest of the plants belonging to family Brassicaceae. In order to identify its parasitoids, sampling was made in the cauliflower fields of southern Tehran from June until October 2011. The pupae were collected from fields and then reared under controlled conditions of 27°C, 60±10% Rh and 14L:10D photoperiod until the emergence of parasitoid adults. These parasitoids were put in alcohol 75°. One parasitoid wasp specimen was collected from the pupal samples. This parasitoid was identified as Brachymeria albicrus (Klug) (Hymenoptera: Chalcididae). This species is a new host record from P. rapae and distribution record from Tehran for the fauna of Iran.
