Abstract

The order Hymenoptera are composed of many species that are beneficial as pollinators and majority are parasitic in behaviour. The presence of an ovipositor instead of a sting distinguishes parasitoids from other hymenopterans. The faunistic composition and relative abundance of parasitic wasps (Hymenoptera: Apocrita: Parasitica) were studied in three study sites with contrasting types of habitat, namely agricultural area, peat swamp forest and urban area by using ten yellow pan traps. A total of349 individuals, 142 species, eight superfamilies and 20 families were recorded from all three locations. The abundance and diversity between each study sites were found to be different. Scelionidae (superfamily Platygastroidea) were found to have the most abundant species in agricultural and urban area. The most abundant species in peat swamp forest was Diapriidae (superfamily Proctotrupoidea). Based on the Morisita-Hom Index, the peat swamp forest has the highest species similarity, while Shannon's Diversity Index revealed that the agricultural ecosystem has the highest species diversity among the other sites. The study also resulted in one species from the genus Mymaromma was sampled, which indirectly adds a second record of the rnymarommatoid species in Borneo. It was concluded that the abundancy of certain families of parasitic wasps are related to their biology as in either being generalist or specialist, as well as the presence of their arthropod host.
