The extent of competition between Asobara tabida Nees von Esenbeck, 1834 and Leptopilina heterotoma (Thomson, 1862), coexisting parasitoids of fruit-inhabiting Drosophila larvae, is still object of study. We investigated whether the two parasitoid species prefer different host species and distribute their eggs differently over the host species available. We studied their behaviour towards the two most important host species, D. subobscura and D. melanogaster, when these hosts were offered in equal numbers. Both parasitoids accepted D. subobscura more often for oviposition than D. melanogaster; accordingly, D. melanogaster was more often rejected. A clear preference for D. subobscura thus existed; this preference was stronger in L. heterotoma. At different host densities, the difference in host selection behaviour between A. tabida and L. heterotoma probably is greater. There is certainly an overlap in the host range of the parasitoids, because both prefer the same host. Some niche differentiation with regard to host selection may nevertheless exist.
