Influence of intra- and inter-specific competition between egg parasitoids on the effectiveness of biological control of Euschistus heros (Hemiptera: Pentatomidae)

•Parasitoid competition can reduce the parasitism rates on brown stinkbug eggs.•In primary parasitism, the parasitoid offspring viability was reduced by superparasitism and multiparasitism.•Trissolcus basalis reduced the reproductive success of Telenomus podisi.•T. basalis was incapable to discriminate parasitized eggs by conspecifics.•In sequential parasitism, the pattern of parasitoid emergence curves changed and it can lead to asynchrony of host-parasitoid dynamic.
