The biological control of soybean stink bugs in Brazil is based on mass rearing in the laboratory and field release of the egg parasitoid Trissocus basalis. Today the brown stink bug Euschistus heros is the most abundant pentatomid on soybean crop, besides, Telenomus podisi has been considered as an important egg parasitoid of soybean stink bug. Laboratory studies were conducted to test the suitability of E. heros eggs to mass rearing T. podisi and T. basalis, compared to the standard methodology (T. basalis multiplied in N. viridula eggs). The eggs of E. heros were exposed to parasitoids by different ways. When individualized eggs were exposed, the parasitism was high (> 96%) but adult emergence rates were low (51.2 and 26.1%, respectively), showing that this egg distribution was inadequate to parasitoid multiplication. When egg masses were exposed to parasitism with eggs on the normal position, obtained emergence rates of 83.1% for T. podisi and 50.6% for T. basalis compared to values of 79.9% and 63.1% with eggs exposed on the positions, did not differed significantly, and showing that the egg mass pulverization methodology was adequate. On cardboard tickets, 162 egg masses or 1193 eggs of E. heros were laid, being 38%, 36.6% and 25.4% of the eggs on lateral, normal and inverted positions, respectively. Parasitism rates of T. podisi and T. basalis (ca. 99%) were similar to that observed with the standard methodology (99.7%). Nevertheless, the emergence rates (50.5& for T. podisi and 60.4% for T. basalis) were significantly lower, probably due a high number of eggs with lateral shrinking, in which there was no development of the parasitoid.
