In this paper, the author provide a world-wide list insects that destroy kissing bugs and others triatominae and tell about results obtained up to now in essayes made for the use of them in biological control against those plagues. They also make a special reference to his experiences made for that purpose. The hymenopterous Oolathron mireyae, new genus and species of Aphelinidae, reared from eggs of Triatoma infestans at Córdoba province, is described and figured. The authors have introduced, under technical control, two species of exotic oophagus parasitoids: Telenomus costalimai Ortiz et Alvarez, 1959 and Ooencyrtus trinidadensis venatorius De Santis et Vidal, 1976, both of them Venezuela. The former does not fell any attraction by T. infestans eggs; on the contrary  the later does. Among the exotic oophagus hymenopterous known up to now and that have been used in experiences against kissing-bugs, O. t. venatorius is the only capable of piercing the corion of eggs with its ovipossitor. Both, the authors and Dr. Mireya M. de Brewer, have obtained argentine generations raised from eggs of T. infestans. Nervertheless, the authors think the releasing of these generations mentioned above in not at all advisable in our country because Conde and Rabinovich have proved in Venezuela that in simultaneous attacks they destroy competitive larvae of T. costalimai and supposethey will behave similarly towards other species of that genus, for instance Telenomus fariai C.
