Resumen:
Several parasitoids simultaneously exploring a host may experience competition between adults (extrinsic) or between their larvae within the host (intrinsic). An intrinsically inferior competitor will coexist with an intrinsically superior one if it locates the host more easily. Piezodorus guildinii (Hemiptera: Pentatomidae) is an important soybean pest and its main natural enemies are the oophagous parasitoids Telenomus podisi and Trissolcus urichi (Hymenoptera: Platygastridae). Our objective was to evaluate the ability of these parasitoids to locate and parasitize hosts. There were no differences in host manipulation between these parasitoids, and both would have similar host location abilities.
