Among the insect pests that affect crucifer crops in Mexico are    Delia   planipalpis    (Meigen) and    D.   platura    (Stein). They are a threat to the production of these vegetables since the damage they cause directly and indirectly affects yield, quality, and commercialization of these crops. Nevertheless, the existence of natural enemies of these dipterans is still unknown. It is fundamental to determine which parasitoids or predators can be considered possible biological control agents in an integrated pest management program.The sampling sites were located in Guanajuato, Puebla, and the State of Mexico, where plants of   Brassica   oleracea   L.   var.   italica   Plenk andcapitata    L.,    B.   napus    L., and    Raphanus   sativus    L. infested with    Delia    spp. were selected. The symptoms observed were wilting, yellowish, flaccid leaves and individuals less developed than the rest of the crop. These plants were extracted with their root and the surrounding soil. Also, wild crucifers were collected, such as    Raphanus   raphanistrum    L.,    Brassica   campestris    L., and    Sisymbrium   irio    L. The first records of    Aphaereta   pallipes    Say (  Hymenoptera  ,   Braconidae  ),    Trybliographa   rapae    (Westwood) (  Hymenoptera  ,   Figitidae  ), and    Aleochara   bimaculata    Gravenhorst (  Coleoptera  ,   Staphylinidae  ) are reported parasitizing the puparia of these anthomyiid flies on cultivated and wild crucifers. This represents only a starting point for the continuous study of these parasitoids, which is needed to consider them useful for the biological control of    D.   planipalpis    and    D.   platura   .
