Experiments were conducted in Londrina, PR, Brazil, under rearing room conditions (25ºC, 60% RH, 14hL:10hD), to evaluated the nymph development and the reproduction of brown stink bug Euschistus heros green stink bug Nezara viridula (Hemiptera: Pentatomidae) as hosts in the eggs parasitoids multiplication. One hundred eggs of E. heros and N. viridula were put into the cage (50x50x70 cm) with soybean plant plus dry soybean and peanut seeds used as diet. Dialy observations were made until adult emergence, and the duration of nymph development time and the survival of adults were calculated. The nymph development time were 33 days for E. heros and 34 days for N. viridula, with survival average of 65% and 71.3%, respectively and there was no significant difference between the trataments. The reprodutive capacity of laboratory and field populations of E. heros and N. viridula were evaluated during February-April 1999. During 13 weeks the egg production per cage was studied with one hundred pairs of stink bugs/cage with the same diet. Dialy observations were made and egg masses were collected. Adults of E. heros reared under laboratory conditions produced 2.08 times more eggs than that collected in field, 5547 and 2262 eggs/ cage to laboratory and field rearing adults, respectively, being this population with high rate of parasitism by Hexacladia smithii, that reduced reproduction and longevity and of adults. The N. viridula adults collected in field produced 1.75 times more eggs than adults reared in laboratory (6304 and 3609 eggs/ cage) and, in this period, it was observed low density of adults parasitized by tachinid flies in the field population.
