Scelio pakistanicus comprised 32.7% of the total parasitism. In nature it attacked Shirakiacris shirakii (17.6%), Spathostermum prasiniferum (29.4%), Aiolopus thalassinus (41.2%) Oxya multidentata (5.9%) and Stenohippus spp. (5.9%). Of the field collected eggpods, S. prasiniferum was the most suitable host followed by A. thalassinus whereas in the laboratory, successful parasite emergence was highest in A. thalassinus (97.3%) followed by Phlaeoba panteli (90%), and Eyprepocnemis plorans (83%). O. multidentata was not a suitable host for development, however, it was parasitized in nature under stress. Since it is a non-specific parasite the predominant grasshopper species will vary from year to year, depending upon the species that was left un-parasitized.
