Abstract

Nasonia is a genus of parasitic wasps, consisting of 4 species. N.vitripennis, N.giraulti, N. longicornis and N. Oneida. Previous research shows that not only females but also males display host specifity. This research controls for and builds further on this research and is divided into three different topics. These topics are related to male host specifity in this genus of wasp. The four topics are: Host specificity on same species, Host specificity between species and the Genetic region of host specificity in males. The setup used in the experiments is an arena setup, where the virgin males got to choose between 2 or more choices. The arena was divided into 8 or 6 parts with alternating options. The results showed consistent and inconsistent results with research previously done by Prazapati et al.. It was found that male N.vitripennis showed a significant preference for the parasitized pupae, but contrary to their work in this research it was found that males could not distinguish between mixed and all male brood. Furthermore it showed that when the male “chooses” a mixed brood pupae it does it at random rather than maximizing the proportion of females inside. For the interspecies host specifity it did not show any significant results for its own or other species. For the BKBWG strain the results were all insignificant except for the white eyed males having a significant preference for parasitized pupae
