Euschistus heros is considered a major pest of soybean in Brazil. In the 1996/97 growing season, the parasitoid Hexacladia smithii was reported for the first time afecting adult populations of the brown stink bug E. heros at the region of Londrina, Parana. In the 1998/99 growing season, the natural incidence was evaluated by colecting 50 female samples at 15 days intervals at Embrapa Soja experimental fields in Londrina. In the laboratory, the reproductive capacity of females was studied during and after soybean season, comparing healthy and parasitized females. From a total of 900 E. heros females collected from December 1998 to August 1999, 40.3% were parasitized by H. smithii. The parasitism varied from 93.3% to 0% with higher occurrence in the months of January and February. At the end of the soybean season the parasitism decreased down to zero by the end of August. When the reproductive potencial of females was evaluated the total average number of eggs layed by healthy females (1133.8) was 5.2 higher than those deposited by parasitized females (216.8) reaching a maximum diference of 9.5 fold in January. The size of egg masses and egg fertility were not influenced by H. smithii parasitism. Results indicated that parasitsm by H. smithii was important for the reduction of the E. heros population during the soybean growing season but its effects was insignificant on the population on diapause. Parasitism also affected the reproductive potential of E. heros females, its influence being drastic on offspring of the populations in December and January, when it acted as a natural control agent.
