Parasitism and survival among rangeland grasshoppers in response to suppression of robber fly (Diptera: Asilidae) predators

, : Parasitism and survival among rangeland grasshoppers in response to suppression of robber fly (Diptera: Asilidae) predators. Environmental Entomology, 141: 20-23

Asilids were manually removed from 0.28- or 0.55-ha circular field plots in Montana 4 or 5 times a week for 6 weeks in order to reduce predation upon dipterous parasites of grasshoppers including Melanoplus sanguinipes and Ageneotettix deorum. Three species that prey upon Diptera, Efferia bicaudata, E. staminea and Mallophorina guildiana, constituted 94% of the asilid population.
