Potential competitive outcomes among three solitary larval endoparasitoids as candidate agents for classical biological control of Drosophila suzukii

Single vs. two species release in an additive design: the combined impacts on the suppression of host Drosophila suzukii were negative by Asobara japonica (AJ) and Leptopilina japonica (LJ) due to interspecific competition but additive by L. japonica and Ganaspis brasiliensis (GB) due to strong interspecific discrimination by G. brasiliensis, regardless of host density.
