Abstract
Effects of 5 species of entomopathogenic nematodes(Heterorhabditis spp.and Steinernema spp.) on the energetic contents in hemolymph of 5th larvae of Galleria mellonella was presented.In all the species the number of hemocytes decreased by over 85% and hemocyte shape was obviously changed 24 hours after treatment.The total volume of hemolymph of 5th larvae infected with nematodes decreased by 73.61%,while esterase activity and content of protein increased.The decrease rate of total carbohydrate content was 14%70%.The results revealed that the entomopathogenic nematodes destroyed the host immune system and dramatically changed the content of energy source in the hemolymph of the host.
