The biology of Euschistus heros (F.) (Heteroptera: Pentatomidae) was studied in laboratory under 24±0.5ºC, 70±10% RH and photophase of 14 h. The mean development time from egg to adult was 38.6 d, and highest mortality (10.4%) occurred during the 2nd nymphal stadium. The mean longevity of adults varied according to sex and sexual activity. Males and females reached sexual maturity at 11.4 and 11.2 d, respectively. The mean time for oviposition after the 1st mating reached 9.1 d for females which mated just once, and 13.9 d for females which mated several times during their life span. The mean number of eggs/female varied from 108.5 to 130.5 depending on the number of times females copulated. It was observed the deposition of single egg and egg masses, at percentages of 71.7 and 77.8 respectively, according to the number of matings of each tested female.
