In november/89 in the insectary of Centro de Estudos "Emmanuel Dias"/Bambui-MG a high infestation by the microhymenoptera T. fariai was found. Among the 529 eggs examined from P. megistus and T. vitticeps, 375(70.9%) of them showed a total of1045parasites (91.4% females and 8.6% males). Later on it was found that T. infestans eggs were also parasitised by T. fariai but not those from R. neglectus. The observedparasitoid/egg average was 7.9 in P. megistus; 8.7 in T. vitticeps and 10 in T. infestans. The present report has special importance considering the real possibility ofT. fariai infestation due to the access of infested triatomine eggs from field captures inducing great damage to colonies maintainedfor research purposes. These eggs have to be carefully examined, isolated and eliminated. This procedure and the closing of triatomine containers with thin net (0.25 mm) is show to be efficient in T. fariai control.
