WebThe results suggest that interference by the autoparasitoid reduced primary parasitoid density, but with no concommitant disruption of host suppression. The results support theoretical predictions that no disruption should occur when both parasitoids are equally efficient and suggest that an autoparasitoid may be as efficient as a primary ... WebMay 25, 2011 · These are expected to be factors that affected autoparasitoid evolution. As for facultative autoparasitoids, males may have different origins, conspecific or heterospecific hosts. In this study we found that the males originated from different host species affected parasitism of autoparasitoid females.
