Conteúdo: 	Laboratory studies were conducted in Londrina and Piracicaba to develop an artificial dry diet for phytophagoys heteropterans. The diet components were: soybean protein (15g); potato starch (7.5g); dextrose (7.5g); Sacarose (2.5g); cellulose (12.5g); vitamin solution (5.0ml); soybean oil (20.0ml); wheat germ (17.9gr); and water (30.0ml). Six different diets with slight variations in their components were tested: 1) Basic diet with rough textura cellulose; 2) Basic diet with rough texture cellulose plus anticontaminant (nipagin) (0.44g); 3) Basic diet with fine texture cellulose plus anticontaminant (nipagin) (0.44g); 4) Basic diet, with half soybean oil and half olive oil, with rough texture cellulose; 5) Basic diet, with half soybean oil and half olive oil, with rough texture cellulose plus anticontaminant (nipagin) (0.44g); and 6) Basic diet, with half soybean oil and half olive oil, with fine texture cellulose plus anticontaminant (nipagin) (0.44g). All diets were  oven dried for 4 hours at 75 C. Diets were wrapped in aluminum foil and kept in the refrigerator. Small cubs of 5x5x5mm were offered to 2nd instars (n = 30) of Nezara viridula (L.) Piezodorus guildinii (Westwood), and dichelops melacanthus (Dallas) (Pentatomidae) at 25 C, RH 60 +- 10% and 14hL:10hD photoperiod. Diets 1,2 and 3 allowed N. viridula nymph survivorship of ca. 70%. With diet 1 all adults abtained were  normal. Survivorship of P. guildinii and D. melacanthus were smaller (range of 12.5 to 50.0%, and 20.0 to 30.0%, respectively, fed on diets 1 to 3). Additional studies with  N. viridula using the basic diet with soybean protein (7.5g) plus lyophilized soybean pods immature (7.5g), yielded the best results, with > 80% nymph survivorship and adult reproduction.
