The competition between Telenomus podisi Ashmead and Trissolcus teretis (Johnson) parasitizing eggs of Diceraeus melacanthus (Dallas) and Euschistus heros (Fabricius) was studied in three different laboratory bioassays to gather knowledge in order to improve stink bug management and to strengthen the preservation of naturally occurring parasitoid species. The impact of parasitoid sequence and time intervals (4 to 192 h) between parasitoid species was evaluated. Competition of Te. podisi and Tr. teretis for the same host favored the parasitoid encountering the egg host first, as it usually outcompetes the second parasitoid. We conclude that it is unwarranted in a short-term goal to release both species together in augmentative biological control programs since the repeated release of Te. podisi led to higher parasitism than any other studied variation of parasitoid sequence. However, simultaneous release of multiple species could be important to help the preservation of the diversity of scelionids in the agroecosystem, a hypothesis that needs to be further investigated in future research.

在三种不同的实验室生物测定中研究了Telenomus podisi Ashmead 和Trissolcus teretis (Johnson)之间的竞争，寄生在Diceraeus melacanthus (Dallas) 和Euschistus heros ( Fabricius) 的卵中，以收集知识以改善臭虫管理并加强自然保护发生的寄生物种。评估了寄生物种之间的寄生序列和时间间隔（4 到 192 小时）的影响。Te的竞争。波迪西和Tr。特雷蒂斯因为同一个寄主偏爱寄生物首先遇到卵寄主，因为它通常胜过第二个寄生物。我们得出的结论是，自反复释放Te以来，在增强生物控制计划中同时释放这两种物种的短期目标是没有根据的。podisi导致比任何其他研究的寄生序列变异更高的寄生。然而，同时释放多个物种对于帮助保护农业生态系统中 scelionids 的多样性可能很重要，这一假设需要在未来的研究中进一步研究。
