(Phaeogenini), Gen.et sp. indet. (Pimplini), Temelucha pestifer, T. sp. nr.pestifer, Temelucha sp. 1 and Temelucha sp. 2 (Hym.: Ichneumonidae); Telenomus dignus, T. rowani, T. sp. nr.rowani and T. (Aholcus) sp. (Hym.: Scelionidae) on Tryporyza incertulas; Trichospilus diatraeae (Hym.: Eulophidae), Apanteles pallipes and Tropobracon schoenobii (Hym.: Eulophidae), Apanteles pallipes and Tropobracon schoenobii (Hym.: Braconidae); Anilastus sp., Gen.et sp. indet.
