The present research describes the defensive behavior of Haplostegus nigricrus Conde (Hymenoptera: Pergidae) larvae exposed to the stink bug predators Podisus nigrispinus (Dallas), Supputius cincticeps (Stal) e Brontocoris tabidus (Signoret) (Heteroptera: Pentatomidae). The main defensive strategy of H. nigricrus seems to be the regurgitation of toxic compounds and the continuous exhibition by the mouth, because all predators died until 24 hours after the direct contact. Only B. tabidus reached the adult phase with H. nigricus larvae as diet what suggests the higher tolerance and hability for detoxication of chemical compounds from that Symphyta.
