Abstract:

Abstract: The parasitism of Orgyia ericae, which causes damage to Ammopiptanthus mongolcus,Heclysarum mongolicum,Hedysarum scoparium and Caragana korshinskii was investigated in Hangjin Qi and Etuoke Qi of Erdosi in Inner Mongolia. The results showed that 8 insect species of the natural enemy were found to parasitize the O. ericae, including Tetrastichus sp. at egg stage, Pimpla disparis、Itoplectis viduata and Aprostocetus sp. at pupa stage, Monodontomerus minor and Aprostocetus sp. at larva pupa stage, Exorista larvarum and one species of Apanteles spp. at larva stage. Among them the ichneumon flies and chalcids were found sometimes to parasitically co-live in a pupa. There was significant difference in parasitism rate on H. mongolicum between the two regions in the same stage, and was also significant difference over the different stage in the same regions and hosts.
