Abstract

Native parasitoids of eucalyptus gall wasp, Leptocybe invasa (Fisher & LaSalle) (Eulophidae: Hymenoptera) and implications on the biological control of the pest.

Abstract

Several hymenopteran parasitoids emerged from eucalyptus plant material infested by the gall wasp, Leptocybe invasa (Fisher & LaSalle), collected during October 2008. These include Aprostocetus gala Walker and Aprostocetus sp. (Eulophidae), Megastigmus sp. (Torymidae) and Parallelaptera sp. (Mymaridae). The extent of combined parasitization ranged from 49 to 74 per cent on severely infested early stage galls (2nd and 3rd). Among the parasitoids, Megastigmus sp. was the most dominant (90.74%) followed by Aprostocetus sp. (6.52%) and A. gala (2.72%).
